There’s activity on the construction side as well, with green stadiums opening in each of the last two years, and another one on the way for 2010. Citi Field, the new home of the New York Mets, just opened in April. Last season brought Nationals Park in Washington, the first Leadership in Energy and Environmental Design (LEED)-certified Major League stadium (it reached the silver level), and next season promises a new park in Minnesota seeking LEED gold.

Building from the ground up gives new parks environmental opportunities that existing parks don’t have. Both Nationals Park and Citi Field have energy-efficient field lighting and waterless and low-flow plumbing fixtures, for example, and both designs incorporate green (vegetative) roofs and white (reflective) roofs to battle the heat-island effect. Additionally, both projects emphasized using recycled steel and concrete, and minimized construction waste sent to landfills.

But it’s not only new stadiums that are getting a green makeover. The previous Red Sox owners were loudly on record as wanting to relocate to the city’s waterfront, where, if they’d wanted to, they could have achieved all sorts of green firsts ­ not to mention considerable new revenue streams. But the owners decided to update the current ballpark instead, preserving not only its historical allure but all its embodied energy, a fact acknowledged by the city last year when it named Fenway one of its 12 greenest buildings.

It is likely that the vast majority of green construction work over the next several decades will also be renovation, not new construction.  MLB is at the end of an epic building boom, and most parks are far nearer their beginnings their ends.

Stadiums “don’t simply get built and then remain intact for 30-40 years,” says John McHale, MLB’s executive vice president for administration. “There’s a lot of rearranging and re-purposing of space, probably at the 8-10 year mark, and then again at 20­about every decade. I expect the renovation work is going to be done with a much higher consciousness to LEED certification than has ever been the case.”

Expanding the Field

And the promotional opportunities are evident to more than just the National Resources Defense Council­which has partnered with MLB­and the teams. All four of the solar installations at MLB parks­at the homes of the Colorado Rockies, the San Francisco Giants, the Boston Red Sox and the Cleveland Indians­were funded in part by local utilities or nonprofits.

In Cleveland, the club was approached by the nonprofit group Green Energy Ohio, the host of the 2007 National Solar Conference, “because they wanted a show piece for the attendees to come see,” says Brad Mohr, assistant director of ballpark operations. The result was a 42-panel, 8.4-kilowatt array.

Mohr, a passionate proponent of renewable energy who now is investigating wind turbines for the club, thinks the panels will not only influence “the average person used to coal burning,” but could also yield an even broader benefit: “What I’m hoping for is that a startup will see that photovoltaics work at this latitude, recognize that Northeast Ohio has an incredibly skilled labor force from the car manufacturing plants that have closed,” and open a plant, he says.

How the Yankees Dropped the Ball

To environmentalists and residents in surrounding New York neighborhoods, a Bronx cheer seems the most appropriate response to the new Yankee Stadium project. They and some of the stadium’s Bronx neighbors are furious at the Yankees and the city for building over 22 acres of public parkland and cutting down 377 mature trees, 70% of the local tree population in a poor area that already had a sky-high asthma rate.

While the stadium accommodates fewer spectators (52,325, including standing room), it boasts more concessionaires, restrooms and nearly double the retail space of the old haunts. There are also more luxury suites: 56 instead of 19, plus 410 “party suites.”  Front-row seats sell for a Ruthian $2,500 each.

But don’t expect to see parks advocates lining up for them at the turnstiles.  “Kids were crying while they chopped down these trees with no warning whatsoever,” says Geoffrey Croft, president of New York City Park Advocates and outspoken opponent of the stadium project.

Critics cite among their grievances the secretive nature of the city’s deal to allow the Yankees to pave over popular Macombs Dam and John Mullaly parks, which was negotiated and signed before the public was informed, they say. Protests and legal actions against the project were unsuccessful.

“Everybody just loves the Yankees so much that they wouldn’t even consider what the people had to say,” says Karen Argenti, a board member of the Bronx Council for Environmental Quality, which also opposed the new stadium. “There were no elected officials who would stand up for the community. It was impossible to get a fair hearing on this.”

The brainchild of Grameen Foundation founder Muhammad Yunus, microfinance is a form of banking whereby financial institutions offer small loans to the poor. The idea behind the concept, which originated in Bangladesh in the mid 1970s, is that motivated and disciplined poor people could climb out of poverty if they had access to funding-even small amounts-that help get businesses off the ground. With access to revolving loan funds, these “micro-entrepreneurs” can build businesses, pay back the borrowed money, and continue to provide for themselves and their families in a sustainable manner.

A classic example would be a woman who borrows $50 to buy chickens so she can sell eggs to other members of her community. As her chickens multiply, she can sell more eggs, and eventually she can sell chicks as well. She pays back the money and has climbed out of a perhaps desperate situation financially-and the community benefits from having a new source of nutritious food.

“Having access to money to start a small business isn’t about fulfilling a dream, it’s literally about keeping their families one step ahead of starvation and putting a roof over their heads,” says Tracey Turner, founder of MicroPlace, an online “microfinance marketplace” launched by eBay in 2007. Individuals can put small or large amounts of money on MicroPlace and get a rate of return in the two- to three-percent range-better than a donation-and get the satisfaction of knowing that their cash is helping someone in a developing country improve their lot and that of their impoverished community.

On the environmental front, microfinance is, in and of itself, “green” in that it promotes businesses that can be sustained indefinitely. Example after example over the last three decades have proven the concept that when poor people are given opportunities to earn a living in a legitimate and sustainable fashion, they have little or no need to pillage their surrounding natural resources to shelter or feed themselves. Also, most of the financial institutions involved in microfinance hold up sustainability as a precondition for awarding loans. Others encourage greener businesses by offering lower interest rates to borrowers with sustainability-oriented plans.

While upstarts like MicroPlace and Kiva (which operates on a similar model whereby individual investors can get in on the microlending fun) are grabbing most of the microfinance headlines these days, Grameen Bank was the first microfinance lender in the world, initiating its first project in 1976 in the Bangladeshi village of Jobra. Today Grameen does a lot more than just offer small loans. It also accepts deposits and provides other banking services, and runs several development-oriented businesses including fabric, telephone and energy companies. And it has spawned thousands of other institutions doing similar things: World Bank statistics show that more than 7,000 microfinance institutions serve some 16 million people in developing countries with $7 billion in outstanding loans, 97 percent of which are repaid.

In 2006, Grameen founder Muhammad Yunus was awarded the Nobel Peace Prize for his efforts.

Dear EarthTalk: What is the so-called “smart grid” I’ve been hearing about, and how can it save energy and money? — Larry Burger, Litchfield, CT

America’s electricity grid is built upon what many consider to be an antiquated principle: Make large amounts of electricity and have it always available to end users whether they need it or not. It’s much like the way most home water heaters work in keeping water constantly hot even when it is not being used. It is also a strictly one-way relationship with utilities supplying power to end users, but not also vice-versa.

The smart grid concept is predicated on a two-way flow of energy-and information-between electricity generators and end users. The system not only delivers power to end users as needed, depending on demand; it also gathers power from end users that produce their own-homes and businesses that generate solar, wind or geothermal power themselves-when they have more than they need.

Some 42 states and Washington, DC already require utilities to have systems in place to buy excess energy generated by their customers. But, writes journalist Michael Prager in E – The Environmental Magazine, “because they can’t know in real time that power is coming in, utilities generate as much as they would have anyway.” He adds that when information flows both ways, end users will be able to send information back to the grid specifying how much power they need and when they will need it. They’ll also be able to communicate when they have excess power available to upload to the grid.

On the forefront of research into the feasibility of the smart grid on a large scale is the Future Renewable Electric Energy Delivery and Management (FREEDM) Systems Center, established in 2008 by the National Science Foundation and headquartered at North Carolina State University. FREEDM is partnering with universities, industry and national laboratories in 28 states and nine countries to develop technologies they say will “revolutionize the nation’s power grid and speed renewable electric-energy technologies into every home and business.” So far, some 60 utilities, alternative energy startups, electrical equipment manufacturers and other firms have signed onto the new partnership.

One such utility, Colorado-based Xcel Energy, has even begun to put smart grid technology into practice on a trial basis for a small percentage of its customer base. The utility has spent some $100 million outfitting 35,000 homes and businesses in and around the city of Boulder with automation and communications capabilities to enable two-way communication of electricity needs.

Xcel won’t have enough data to assess energy and cost savings until early 2010, but analysts are optimistic that the utility’s costly experiment will reap benefits down the road for consumers, utilities and the environment. Indeed, environmentalists and economists alike have high hopes that widespread implementation of such “intelligent” systems could help usher in a new age of unprecedented energy efficiency, emissions reductions and cost savings around the United States and beyond.

Also in the high-priced range is the Tributaries T12 power strip, with eight rotating power receptacles and Ethernet, phone and cable protection.

It’s $120, which is too expensive for anything labeled a “power strip” that doesn’t include a uninterruptible power supply/battery backup for your gadgets. I don’t care what brand or label it falls under.

That said, it’s a damn shame the T12 costs over $100, because it’s one of the handiest power strips/surge protectors I’ve ever used.

Eight of the 12 sockets rotate 90 degrees to get whatever AC adapter you’re using out of the way of everything else. The 12 also delivers 4320 joules of surge suppression. It’s rated for 15 amps for up to 1875 watts of load — enough for several computers or your entire home theater and much more. It also offers a $25,000 warranty on plugged-in devices.

We’re basically rounding out the year with this review, because we started 2008 by introducing everyone to the Powramid — an innovative pyramid-shaped power strip.

Like the Powramid, the T12 is superior in almost all ways (except cost of course) to traditional power strips. The sockets are arranged — and move — to accommodate all of your many gadgets.

Plenty of people on the blogs have asked why you need 12 plugs. I’m a big nerd, but I don’t run a multiple display setup or keep my video game consoles on my desk. I managed to basically fill up the T12 with what I would think is a normal amount of computer junk:

• Computer
• Monitor
• Cell phone charger
• Wireless mouse charger
• External hard drive
• Cable modem
• Router
• Printer
• Computer speakers
• Digital camera charger

So it’s not the plugs that are the problem.

Price is the problem, and there are somewhat comparable products out there for less.

Just be careful. Don’t go to the dollar store and buy “Joe’s brand surge protector” and be aware of the cheap imitations of the cheap imitations with fake UL certifications.

Bottom line: you don’t absolutely need to spend $120 for a decent power strip, but if you’re spending thousands on a home theater with all the trimmings, don’t think you can get away for a $5 one either.

With some 30 to 50 million Americans suffering from various degrees of lactose intolerance, and an estimated three million of us now eating animal-free (vegan) diets for humane, environmental and/or health reasons, the production of alternatives to dairy products has started to become big business.

But while substitutes for milks and ice creams abound, mostly soy- or rice-based blends that have come a long way since they first appeared on grocery shelves, finding satisfactory alternatives to the many varieties of cheese can be a challenge. But the choices are expanding rapidly.

The first place to look might just be your regular supermarket’s produce section-that’s often where you’ll find Galaxy Foods’ Veggie line of non-dairy cheeses. After all, they are made from soy, a crop. Galaxy’s offerings come shredded, grated, in slices and in hunks. Fans swear they taste just like the real thing. And they are all excellent sources of calcium without cholesterol, saturated/trans-fats or lactose.

Galaxy also offers cheeses made from rice. And while some of both the Rice Brand and Veggie line contain small amounts of cultured milk salt, dried skim milk protein and trace amounts of lactose, Galaxy also make two purely vegan varieties, usually found in the dairy sections of grocery or health food stores.

A few other popular brands made with rice include Rice Slices and Lifetime Low Fat Jalapeno Jack Rice Cheese. Check the shelves of your local organic or natural food market to find one or more to sample.

Another leading producer of dairy-free cheeses is Scotland’s Bute Island Foods. The company began making its own vegan hard cheese alternatives (sold under the Sheese brand name) in 1988, and has since expanded into cream cheese alternatives (Creamy Sheese) as well. From pizzas to sauces to sandwiches to spreads, Bute Island has vegan and lactose-intolerant cheese lovers covered.

Some other soy-based choices that get good reviews include Good Slice Cheddar Style Cheese Alternative (great for sandwiches), vegan-friendly Tofutti Soy Cheese Slices, Follow Your Heart’s Vegan Gourmet (pizza, anyone?), and Teese (it melts with the best of them), among others.

Do-it-yourselfers might want to experiment with making their own non-dairy cheese using ingredients such as tofu and yeast. A quick web search will yield many recipes for making cheese and for using non-dairy cheeses in favorite dishes. Many of the best are collected in Joanne Stepaniak’s The Ultimate Uncheese Cookbook, available in some bookstores as well as from Amazon.com and other online vendors.

With so many good choices, not to mention recipes for home cooked varieties, many a vegetarian may just make the leap into full-fledged vegan eating. And existing vegans can rejoice: French Onion Soup (dairy-free, of course) is back on the menu.

Dear EarthTalk: Can those energy-efficient compact fluorescent light bulbs that are popular now cause headaches because of the flickering they do? I converted my whole house over last fall and both my kids were complaining of headaches on and off. – Sandy, Eugene, OR

With a switch to energy efficient compact fluorescent (CFL) light bulbs already in full swing in the U.S. and elsewhere-Australia has banned incandescents, Britain will soon, and the U.S. begins a phase-out of incandescents in 2012-more and more complaints have arisen about the new bulbs causing headaches.

Many experts say that the issue is being overblown, however, that there is no scientific evidence that the bulbs cause headaches and that a kind of hysteria has grown out of a small number of anecdotal reports.

Industry experts acknowledge that day-to-day exposure to older, magnetically ballasted long tube fluorescent bulbs found mostly in industrial and institutional settings could cause headaches due to their noticeable flicker rate. The human brain can detect the 60 cycles per second such older bulbs need to refresh themselves to keep putting out light.

However, modern, electronically ballasted CFLs refresh themselves at between 10,000 and 40,000 cycles per second, rates too fast for the human eye or brain to detect. “As far as I’m aware there is no association between headaches and the use of compact fluorescent lamps,” says Phil Scarbro of Energy Federation Incorporated (EFI), a leading distributor of energy efficiency-related products-including many CFLs.

But Magda Havas, an Environmental & Resource Studies Ph.D. at Canada’s Trent University, says that some CFLs emit radio frequency radiation that can cause fatigue, dizziness, ringing in the ears, eyestrain, even migraines. You can test to see if CFLs in your home give off such radiation, she says, by putting a portable AM radio near one that’s on and listening for extra static the closer you get. She says that such electromagnetic interference should also be of concern to people using cell phones and wireless computers.

Sometimes headaches are due to eyestrain from inadequate lighting. When replacing an incandescent bulb with a CFL, pay attention to the lumens, which indicate the amount of light a bulb gives out (watts measure the energy use of a bulb, not the light generated). A 40-watt incandescent bulb can be replaced by an 11-14 watt CFL because the lumen ouput is approximately the same (490); a 100-watt incandescent can be replaced by a 26-29 watt CFL, both providing about 1,750 lumens. If you’re still skeptical, replace a 40-watt incandescent with a 60-watt equivalent 15-19 watt CFL, which will boost lumens to 900.

Another consideration is color temperature (measured in degrees “Kelvin”). CFLs rated at 2,700 Kelvin give off light in the more pleasing red/yellow end of the color spectrum, closer to that of most incandescents. Bulbs rated at 5,000 Kelvin and above (usually older ones) give off a less pleasing white/blue light.

The Environmental Defense website provides a handy chart comparing the watts and lumens of incandescents versus CFLs, along with further discussion about color temperature.

According to The Wall Street Journal’s Rebecca Smith, a 42-inch plasma TV set can draw more power than a large refrigerator, even if the TV is only used a few hours a day. This is partly because many newer models don’t turn off but go into “standby” mode so they can start up fast later with no warm-up period. “Powering a fancy TV and full-on entertainment system-with set-top boxes, game consoles, speakers, DVDs and digital video recorders-can add nearly $200 to a family’s annual energy bill,” she adds.

Smith recommends green consumers consider the Liquid Crystal Display (LCD) models, which typically uses less energy than comparable plasma sets. According to the U.S. Environmental Protection Agency (EPA), a 28-inch conventional cathode-ray tube (CRT) set uses about 100 watts of electricity. A 42-inch LCD set might consume twice that amount, while plasma could use five times as much, depending on the model and the programming. For the largest screen sizes (60 inches and up), projection TVs are the most energy efficient, clocking in at 150-200 watts-significantly less than the energy a plasma set would use.

“What scares us is that prices for plasma sets are dropping so fast that people are saying, why get a 42-inch plasma set when you can get a 60-inch or 64-inch one,” says Tom Reddoch of the non-profit Electric Power Research Institute. “They have no idea how much electricity these things consume.”

For its part, the industry is taking some steps to make its products more efficient, and to improve disclosure of energy usage. In June 2008 Sony pronounced its new 32-inch Bravia KDL-32JE1 LCD model “the world’s most energy efficient television.” Slated for sale in Japan in August 2008 for around $1,400, the new set utilizes fluorescent tubes to create higher levels of brightness with less energy consumption, but still delivers large resolution, a high contrast ratio and a wide viewing angle.

Beginning in November 2008, forward-thinking manufacturers will get a little boost from the U.S. government, which will start awarding the most energy efficient new TV sets “Energy Star” labels to help consumers identify greener choices. TVs bearing the Energy Star label must operate at least 30 percent more efficiently than standard models in both stand-by and active modes. Consumers can see which models qualify by visiting the televisions section of the EnergyStar.gov home electronics page. According to the EPA, if all TVs sold in the U.S. met Energy Star requirements, yearly energy savings would top $1 billion and greenhouse gas emissions would drop by the equivalent of taking a million cars off the road.

Of course, the greenest option of all (aside from getting out from in front of that tube and spending more time outdoors) is to keep or repair your existing CRT unit (a digital-to-analog converter will be needed after February 2009 when new signal specifications go into effect). Most CRT sets use less energy than any of the LCD or plasma models, and if it ain’t broke, why fix it? Buying a new TV, even a greener one, only generates more pollution in production and transport, and creates waste in junking the old model.

Dear EarthTalk: I heard that children are reaching puberty at earlier ages now and that it may have to do with environmental toxins and even their TV viewing habits. Can you enlighten? – Mark Abbot, via e-mail

To say that kids are growing up faster than ever these days may be more than just cliché. Recent studies have shown that children are reaching puberty at younger and younger ages, and researchers are starting to see links between this trend and other societal ills such as ubiquitous pollution and sedentary lifestyles.

In a 2007 report for the Breast Cancer Fund entitled “The Falling Age of Puberty in U.S. Girls: What We Know, What We Need to Know,” ecologist Sandra Steingraber argues that unfettered access to computers and TVs over the last 30 years has led to an increasingly sedentary lifestyle among kids in the U.S. and beyond. Active kids produce more melatonin, a natural hormone that serves as the body’s internal clock and calendar. This could explain why sedentary kids are likely to go through puberty sooner: Their bodies think their decreased melatonin production is a trigger to move into puberty. “[Melatonin is] an inhibitory signal for puberty,” says Steingraber. “The more melatonin you have, the later you go into puberty.”

Of course, sedentary lifestyles are also linked to childhood obesity, a condition that often continues-along with the many health problems that can accompany it-into adulthood. A recent National Health and Nutrition Examination Survey (NHANES) found that, between 2001 and 2004, 17.5 percent of children ages six to 11 were overweight-an effective doubling of obesity rates three decades ago. A study by the non-profit Obesity Society came up with a slightly higher figure-20 percent-with the percentages higher for Hispanic, African-American and Native American children.

Obesity is certainly one factor in the surge in so-called “precocious” adolescence, but chemicals are also thought to play a role. According to Erin Barnes, writing in E – The Environmental Magazine, a study comparing the body mass index of Danish and American girls found that the former group hit puberty a full year later than the latter even though their weights were in the same range. Another study found that wealthy girls in South Africa reach puberty a full year after their African-American counterparts. “Many researchers,” writes Barnes, “are studying the relationship between chemical pollutants like PCBs (polychlorinated bphenyls) and phthalates (commonly used plasticizers) and premature development.”

Some researchers believe that the preponderance of synthetic chemicals in more developed societies are interfering with human endocrine development and essentially “tricking” kids’ bodies into going through puberty prematurely. Also, precocious puberty in girls has been linked to breast cancer, as well as higher rates of drug abuse, violence, unintended pregnancies, problems in school and mental health issues.

“Shortening childhood means a shortening of the time before the brain’s complete re-sculpting occurs,” says Steingraber. “Once that happens, the brain doesn’t allow for complex learning.” She adds that the brain can only build the connections used to learn a language, play a musical instrument or ride a bike before it gets flooded with the sex hormones that come with the onset of puberty.

Carpenter ants may seem small and look harmless, but they can do serious damage to anything wooden in your home, including not only furniture but also the very framing and walls that hold up the house. If you are seeing a lot of ants or small piles of sawdust-like material in random spots in or around your home, you are most likely suffering from a carpenter ant infestation.

Ants are very social beings and form large colonies before spreading out to find additional nest sites. They thrive by hollowing out wood, especially in moist or rotten spots, to build their nests and then use their new home in your walls and chairs as a base camp from which to forage for food and water in their nearby surroundings. Indeed, their very presence is a good indication of moisture or rot problems in the wood, so homeowners may have more work on their hands than simply exterminating carpenter ants.

In the northern latitudes of the continental U.S. and in much of Canada, carpenter ants are the most common insect wood destroyer, surpassing even the mighty termite. But while many commercially available chemical pesticides will rid a structure of carpenter ants, homeowners are increasingly steering away from such toxins proven to impact the human nervous, respiratory and reproductive systems.

Perhaps the most economical and effective way to get rid of carpenter ants is by applying boric acid (also known as borax) to their nest sites and surroundings. This natural non-toxic element, mined from below the Mojave Desert in southern California, has a long history of use in exterminating brazen populations of cockroaches, palmetto bugs, waterbugs, silverfish, termites, and, you guessed it, carpenter ants.

Al Abruzzese, owner of the website Al’s Home Improvement Center, swears by boric acid to get rid of wood-boring pests. “This simple inexpensive, household chemical is deadly to all insects,” he says. “It has been shown to attack their nervous systems, as well as being a drying agent to their bodies.”

Beyond just being effective as an all-natural insecticide, boric acid is non-toxic to humans. Abruzzese says it is safe enough to use around children-it has been used in ointments and salves for diaper rash on babies in the past-and can be an important part of eyewash solutions as well, albeit in very diluted form (don’t try it at home). One common brand name to look for is Nisus Bora-Care, but any pesticide with boric acid or borax listed as an active ingredient will do just fine.

For those not into do-it-yourself pest control, calling in an exterminator that uses all natural products is a good option. Oregon’s All Natural Pest Elimination, for instance, services the entire four state region of the Pacific Northwest with products from Natureline-crafted from safe botanical extracts and essential oils, not synthetic chemicals-on all of its extermination jobs. Look in the yellow pages for exterminators in your area, and call each one you are considering to make sure they stay away from noxious chemicals.

Dear EarthTalk: What is “cogeneration” as a means of providing heat and power? – Jerry Schleup, Andover, MA

Cogeneration-also known as combined heat and power, distributed generation, or recycled energy-is the simultaneous production of two or more forms of energy from a single fuel source. Cogeneration power plants often operate at 50 to 70 percent higher efficiency rates than single-generation facilities.

In practical terms, what cogeneration usually entails is the use of what would otherwise be wasted heat (such as a manufacturing plant’s exhaust) to produce additional energy benefit, such as to provide heat or electricity for the building in which it is operating. Cogeneration is great for the bottom line and also for the environment, as recycling the waste heat saves other pollutant-spewing fossil fuels from being burned.

Most of the thousands of cogeneration plants operating across the United States and Canada are small facilities operated by non-utility companies and by institutions like universities and the military. For small cogeneration plants-those that generate anywhere from one to 20 megawatts of power-biomass or even methane from garbage dumps can be used as a front-end fuel source, but natural gas is far more common as the primary input.

For instance, Sunnyvale, California-based Network Appliance Inc., a computer networking company, relies on a one megawatt natural gas-powered cogeneration system to power the building’s extensive air conditioning needs, and for back-up power for use during peak demand times. The company estimates it saves around $300,000 a year in energy costs thanks to the cogeneration system.

In another example, Illinois-based Epcor USA Ventures operates three mid-sized (25 megawatts and up) cogeneration power plants in San Diego to power U.S. Marine Corps and Navy bases there. All three plants work in the same way: Natural gas turbines drive electrical generators that in turn exhaust hot gases. These are then captured to drive a steam generator hooked into the bases centralized heating and cooling systems. Since the systems generate power to spare, Epcor is talking with area companies about kicking in for a share of the steam to keep their energy bills and carbon footprints in check.

Cogeneration is not limited to stationary power plants. Honda is exploring the use of a specialized automotive cogeneration generator designed to improve the overall efficiency of hybrid vehicles by recapturing waste exhaust heat from the internal combustion engine and converting it to electricity to recharge the battery pack. The idea is still in the research and development phase, it could make its way into new cars within a few years, further improving on the already impressive efficiency of hybrid cars.

The “Powramid” is a six-outlet cone of a power strip that’s actually pretty smart. It lets you plug large power adapters into each socket and is extremely compact.

Kreative says several models of the product are coming, but right now, their website only shows one, the E-900H.

Now, there’s not much to say about a surge protector, but you have to give these guys some credit for doing something different in the relatively vanilla world of surge protectors.

The E-900H will retail somewhere between $17-25, said Bonnie Jiang, Kreative’s sales director, in an interview Wednesday. The product will come in a wide variety of body and indicator light colors as well.

They’re also offering free t-shirts to anyone who preorders.

Kreative plans to highlight their new toy at CES, January 7-10 in Las Vegas.
