GE Announces New Line Of Efficient Tankless/Hybrid Water Heaters
Tankless water heaters always seemed to make a lot of sense to me. I mean, hot water on demand as opposed to hot water sitting and waiting — seems smart, right? Everytime I go away on vacation, I lower the temp on my water tank to conserve energy, but I know I’m in a small minority. Most people probably go along heating water even when they’re not home for extended periods of time.
Which is why I’m jazzed about GE’s new line of tankless water heaters. For those that don’t need tankless, the electric-hybird heater they’ve got waiting in the wings looks pretty sweet as well. According to the release, the gas tankless on-demand heaters will “save 25 percent in water heating costs on an annual energy bill in comparison to a standard 40-gallon gas tank.” Additionally, the unique design can help avoid up to 25 percent of CO2 emissions tied to water heating.
Even better, earlier today the U.S. Department of Energy created the first ENERGY STAR standard for water heaters. Ironically, water heating was the only major residential energy product that did not have an ES designation — even though it’s one of the largest energy consumers in the household.
Of course, not everyone has access to gas (and truly, for those of us building green homes, reducing the use of fossil fuels is probably on the short list) so GE is getting ready to launch an Electric-Hybrid water heater for next year. According to early tests, this hybrid would reduce typical water heating energy consumption by more than half. While the typical home might use 4800kwh/year, the GE model consumes only 2300kwh/year. Plus, it would retain the same footprint of standard water heaters allowing easy installation.
Harnessing The Power Of Luffas For Shade And Sponges
If you’re a regular reader, you no doubt know we here at Groovy have a fascination with the seemingly magical properties of the Luffa. Not only can it be harvested to create the sponge-like scrubber most people love in the tub, but it can also help shade your home and keep things cool in the heat of summer. Just ask John Lawvere — an entire side of his trailer in Arizona is shaded from the sun with several Luffa vines. Additionally, he makes some extra cash from his crop by selling the “sponges” for $5/each come harvest time. Says John,
“I teach Physics at a community college in Tucson, AZ. My remodeling/plumber friend helped me a lot at building supports for Luffa vines. We have an idea about building structures over parking lots (near apartment complexes and other businesses) to save those people money on air conditioning while producing a valuable crop.”
Not a bad idea, right? We applaud John and his amazing “Luffa Tunnel” — something he says “convinced my girlfriend’s mother (in Belarus) that I was a good man.” Ha, nice.

A Treehouse For Adults That’s Also Yours To Rent
I’ve passed this treehouse before while stumbling online, but on my second time ’round I thought it was beautiful enough to pass a mention here on Groovy.
Located in wild, gorgeous British Columbia, this 15ft. tall platform home is built upon 7 trees. As one would expect, it also features some incredible design characteristics that look like something out of The Lord of the Rings; including carvings, 2 handmade spiral staircases, and rustic furniture. You’re even treated to a beautiful view of the Rocky Mountains from the living room. All this, and it’s only $150/night with access to over 320 acres of hiking, fishing, and lake activities.
Interested? Jump on over to enjoy life in the trees. Your inner-kid will thank you.
Beijing’s Olympic Aquatic Centre Is A Green Wonder
Just in time for the 2008 Olympic games in Beijing, the official grand opening of the Olympic Aquatic Centre took place this past Monday in celebration of its unique architecture and eco-friendly characteristics.
The building, four years in the making, is nicknamed the “Water Cube” and is a rectangular-shaped steel design covered by a membrane of brightly lit blue bubbles. Not only are these stunning to look at, but they also serve an important purpose in reducing energy costs by 30%. The membrane is made out of a material called ETFE, (Ethylene Tetrafluoroethylene) which absorbs solar radiation and reduces thermal loss. Very similar, I suppose, to the way a solar cover works on a pool.
Not only is ETFE recyclable, but it’s also very strong; capable of bearing up to 400 times its own weight. Gizmag fills us in on additional details,
Green Roof Proposed For Stretch Of California Highway
This sounds like a wonderful idea — if anyone happens to have $200 million lying around.
A plan has been submitted to cover a stretch of California highway with a 24-acre park. It would be built on a deck constructed over the below-grade portion of the Hollywood Freeway (US-101). Organizers argue that by placing a “cap” over one of the world’s most congested freeway systems, the necessary ventilation system would clean the air before re-circulating it back into the environment — creating a positive improvement in air quality for LA. Additionally, the park would also provide a nexus between East Hollywood and Central Hollywood–”alleviating the strain on the community from the initial creation of the freeway through this section of Hollywood.” From the site,
Eco Sac: The Water Bladder For Your Home
If giant rain barrels aren’t aesthetically pleasing or you lack the room for installation, you may want to consider the Eco Sac; a flexible rainwater bladder storage system that hides away under decks or floors. Each sac is manufactured using “industrial strength fabric sealed by high frequency welding.”
According to the site, the eco sac is better than your average rain barrel because a.) it captures water faster than rigid tanks, b.) you can use multiple bladders which all fill at the same rate and at the same time c.) it is guaranteed not to leak and d.) it is algae resistant and the water stored is potable.
Pretty cool idea for those with limited space to capture rainfall. There are 54 different sizes to choose from, ranging from 2,200 liters to 8,600 liters. Apparently, you can join multiple sacs together to get up to 50,000 liters or more water storage.
Much like the portable grey water recycler we wrote about earlier this week, this product is currently only available in Australia. Something tells me however — with the water woes currently affecting parts of the U.S. — that we’ll be seeing more of these stateside shortly.

Town Decrees Solar Panels Ugly, Family Fights Back
I always find amusing the rules that some of my friends around the country must abide by when living in community housing developments. Your grass can only be so high, children’s toys must be kept to a minimum outside, your house can only be certain shades of color, etc. etc. It’s a frightening utopia of meaningless laws and trivial worry. When I heard that the town of Scarsdale denied a family the opportunity to put up solar panels — on the basis that they were ugly and “not in keeping with the character of the community” — I immediately wanted to cry/laugh. You have got to be kidding me.
But then I thought that such reactions are probably not too uncommon. We live in a world with designer water, designer shampoo, and animal spas. People have become so accustomed to modular cookie-cutter homes with white picket-fences and weed-free sidewalks — that they’ve actually forgotten there’s a world of people out there who could care less and actually would like to live a unique existence; with character and vision for their own lives. So, when you move to a place like Scarsdale, and they deny you the ability to lead that existence based on the above criteria, what do you do? You call their bullshit and fight back.

How To Build A Hobbit House (That You’d Actually Want To Live In!)
Just found this link to a beautiful ‘How-To’ that takes you through the steps of building your very own low-impact woodland home. It’s appearance is very similar to the Hobbit homes featured in Lord of the Rings, but the aesthetics of the design also make it a piece you might find in Better Homes and Gardens. The cost? The author estimates total expenditures of about $6,000. This, and about 1000-1500 labor hours to put everything together. From the site,
“Take one baby, a toddler and a building site. Mix well with a generous helping of mud, combine with 6 weeks of solid welsh rain whilst living under canvas. Do this in candle light without a bathroom or electricity for three months. Chuck in living with your father for good measure. Top with an assortment of large slugs. The result a hand crafted home of beauty, warmth and health for about 3,000.”
