Energy for lighting is one of the main resource hogs around the world. Staring at an image of the earth at night, it doesn’t take much to see how dependent we are. The recent shift to the CFL bulb has helped ease the burden of paying for energy costs, but its role in the lighting world may only be a stepping stone to the next, great efficient successor: the LED.
LEDs (or Light-Emitting Diodes) will slowly become the lighting standard over the next decade. But light bulbs won’t be the only products to take advantage of their efficient properties. A variety called OLED (or Organic Light-Emitting Diode) are thin, organic materials sandwiched between two electrodes, which illuminate when an electrical charge is applied. This technology is behind all those cool flexible displays and electronic ink displays we’re always seeing. They’re so thin, that they could be applied to rooms as a type of wall paper to glow at the touch of a finger or when someone enters the room. Till now, the process of commercially manufacturing OLEDs has remained expensive. However, a recent breakthrough from GE hopes to lower the cost-barrier and show that OLED can be created “roll to roll”. From the article,
We’ve all heard of alternative sources of energy from sunlight, water, and wind — but how about blood? An inventor by the name of Jim Mielke has created a bluetooth-ready, wireless, blood-fueled display that uses tiny microscopic spheres, somewhat similar to tattoo ink, to display images. Here’s how it works:
The basis of the 2×4-inch “Digital Tattoo Interface” is a Bluetooth device made of thin, flexible silicon and silicone. It´s inserted through a small incision as a tightly rolled tube, and then it unfurls beneath the skin to align between skin and muscle. Through the same incision, two small tubes on the device are attached to an artery and a vein to allow the blood to flow to a coin-sized blood fuel cell that converts glucose and oxygen to electricity. After blood flows in from the artery to the fuel cell, it flows out again through the vein.
Green SAHM is one of my favorite blogs in my RSS reader. Her latest post is on saving energy when cooking. Tips vary from keeping a lid on the pot on the stove, to analysis of energy costs of different cooking methods (microwave, electric oven, gas oven, slow cooker. Definitely worth a look!
From How to Use Less Energy While Cooking
As a kid, no sandbox was complete without a fleet of Tonka dump trucks. Today’s kids have much cooler options; particularly if this design from Haishan Deng makes it from the drawing board and into the real world. It’s called the Super Tipper Truck and features independent suspension and electric motors in all four wheels. This allows for greater versatility in loading and unloading positions; as well as the ability drive down into pits and deliver cargo — something normal tipper trucks would have difficulty doing.
For more details, as well as a great in-depth interview with the designer, head on over to gizmag.
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,
Got 14 minutes? With this new eco-friendly washing machine from Beko, you’ll be throwing some clean clothes up on the line pretty quick. Its latest release is a tricked-out, energy efficient marvel with a 14-minute wash cycle. The benefits for those that are energy-conscious are evident, but the technology inside this thing also calculates the exact amount of water required according to the type and quantity of the laundry. For those suffering through some intense droughts, this might be a wonderful option for conservation.
Beko has already received an eco-award for its energy efficiency. The only thing one hopes is that the models will be carried beyond the UK. Current price is a reasonable £349.
One the largest hurdles to people and businesses embracing solar energy is the cost. The panels themselves make up a great deal of total expense, but there are also additional components to consider to get that energy working with your home. The most common accessory to any good solar installation is the inverter. This piece of equipment converts the solar panel’s DC energy to AC. A new firm called Enphase Energy hopes to remove this cost and produce micro-inverters; so small that each panel will receive their own. From the article,
A company named Marquiss Wind Power has successfully finished raising $1.3 million for development of its Ducted Wind Turbines. Unlike their much larger counterparts, ducted turbines are boxy and stand about 19ft tall. Despite what appears to be aerodynamic disadvantages, this shape actually allows the turbine to re-orient itself according to the direction of air flow; something that can be a bit random in urban centers. The ducting is intended to increase wind speed as it approaches the blades. According to the website, these factors combine to allow the power output from the MWP turbine to exceed that of any traditionally designed comparable turbine. From the article,
At the moment, two models are sold — one intended for areas with wind speeds of 6-10 mph, and another for higher average speeds. The turbines are intended for buildings between one and three stories tall.
It sure ain’t elegant — but there’s a lot of science at play with this design. I especially like that AeropointT500 can operate in low wind speeds. I have no ideas on price — but hopefully that $1.3 million will go a long way to fleshing this product out a bit more.
While we’ve seen solar cell efficiency squeak past 40% in labs this year, we’re still stuck commercially with panels that at most convert about 20% of what hits them into energy. Then there’s the whole “darkness” thing that cuts into production for part of the day.
Researchers at the Idaho National Laboratory have potentially solved both issues by turning to another hot field: nanotechnology. From the article,
With this new technology, millions of extremely small twists of metal are molded into banks of “microantennas”, which can be placed on almost any material, including plastic sheets. These spiral shaped “microantennas” are about 1/25 the width of a human hair. They are so small that they resonate from the interaction with the sun’s infrared rays. This resonation can be translated into energy. During the day, the Earth soaks up a lot of this infrared energy, which is then radiated out at night — enabling these microantennas to collect power even after the sun has set.
With a top speed over over 70mph and a range of almost an equivalent amount, the Veunturi solar car allows you to draw stares while commuting to work in Formula One style. 3.6 sqm of photovoltaic cells operating at 21% efficiency work to power what is considered the first ever commercial vehicle that’s capable of using absolutely no fossil resources. From the site,
“Capable of working with very little energy (16 kWc motor) and of recharging even when in motion, this vehicle of another era does not need to be permanently exposed to the sun in order to move. Its last-generation NiMH Venturi NIV-7 batteries ‘liquid cooled’ in fact enable it to restitute stored energy, whether solar or from the electricity supply, making it the first electro-solar hybrid vehicle. To attain this level of performance while using very little energy, Astrolab has been designed like a Formula 1 : its carbon monocoque chassis is ultra-light and serves as an oversized protection cell ensuring the safety of its occupants in the event of a collision. Its profile recalls the aqua-dynamic design of great racing yachts.”
Yum.
Our friend Ruben Miller sent us an email on an alternative energy concept him and his wife submitted to the Metropolis’ Next Generation 2007 competition and we think it’s pretty cool. While the idea of harnessing human energy has been around for awhile, this one actually seems feasible. From the article,
“Imagine a nightclub where dancers generate the venue’s electricity just from the impact of their steps. With Redmond’s innovative flooring system, this vision of a human-powered energy source may be close to a reality. The floor tiles, cast in durable concrete and recycled glass, are fitted with piezoelectric brass-reinforced ceramic plates covered in nickel electrodes. With the impact of each footstep, a metal pointer inside the tile compresses the ceramic plate, generating an electric impulse. The resulting voltage activates four LED lights, visible through the glass surface, allowing energy-generating participants to see the power of their steps.”
This type of technology is intended for high-traffic areas; sidewalks, playgrounds, school hallways, etc. Obviously, you could do away with the LED lights and incorporate the idea into flooring that makes the whole thing less obvious. We love the concept, however, and hope Elizabeth and Ruben keep pushing to make it a reality.
I don’t care who you are, this right here is pretty darn cool. What an interesting way to reuse an old car and make a nice commuter vehicle, although it appear he may have gone overboard!
When the starting light flashed, the Datsun, known as White Zombie, shot silently past the Corvette and kept widening the lead as the two cars faded into the distance. “Oh man, right off the [starting] line he had me,” said the Corvette’s owner, Robert Akers, shaking his head.
The electric car renaissance is barely spreading ink on the canvas and already plans are in motion to have a viable charging infrastructure in place. Earlier this week, Tesla Motors — the crew behind the highly anticipated 2008 Tesla Roadster — received a grant from the California Air Resources Board (CARB) to develop a 16KW station that could be installed at hotel chains across the state. While the stations would be commercially based, we have no idea if they might also be autonomous through solar power; much like the stations Vectrix is planning on introducing in Europe.
Tesla also recently announced plans to form a new division that will sell batteries to other car manufacturers.
“The electric-car startup said it will initially provide advanced lithium-ion battery packs from the new Tesla Energy Group to Think, a Norwegian maker of electric cars. The deal is expected to bring Tesla $43 million over the next two years. The new division will also develop and make battery packs for Tesla’s two-seat roadster that is set to go into production this fall, and for a four-door sedan set to debut later this decade.”
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. From the article,
Imagine if to go wireless, mobile phones companies made you purchase a kit to install your own tower for $8k, and then shipped you a box of minuscule widgets and a soldering gun that you have to somehow assemble into a Razor. I’m pretty sure the market density of cell phones would be about as weak as that of PV, because that is the marketing strategy that Solar Energy is currently operating under.
Now imagine you could sign a contract, and have clean, green solar energy installed at your home by professionals and pay a nominal monthly fee based on your usage with no initial outlay. Tempted? The Citizenre Corporation is counting on it. What they are offering is the chance for average Americans to have the privilege of a Solar Array on their roof. According to their website it will be as simple as having one of their technicians do a site assessment, the signing of a 1,5,or 25 year forward rental agreement (FRA) and a safety deposit of $500 (reasonable for $25k in equipment!). At the signing of the agreement you will lock in your current cost per KwH and pay Citizenre that amount for any watts their equipment sends into your home thru an interconnected inverter. For anyone who is remotely Eco Aware this is Earth Shattering. But that elation is followed immediately by “where’s the catch?”. Talk to a REnU rep and they answer simply “there is none!”. Hmmm.
News from the EPA:
“EPA is the first and only major federal agency to purchase green power equal to 100 percent of its estimated annual electricity use nationwide.
As of September 2006, EPA will be purchasing nearly 300 million kilowatt hours (kWh) of green power annually in the form of renewable energy certificates (RECs) or delivered product. This amount is equal to 100 percent of the total estimated annual electricity consumption at all of EPA’s nearly 200 facilities across the country enough electricity to power 27,084 homes for an entire year.”
“616,279,179 pounds of carbon dioxide (CO2) emissions will be avoided annually the equivalent to removing 53,824 cars from the road for an entire year.”
I think this is good news, now if the rest of the U.S. Government will follow the example of the EPA we will see some huge changes… something tells me this may be a ways off.
I’ve recently received a number of emails calling for me to Kick the Oil Habit by supporting E85 which is a liquid fuel made up of 85% ethanol and 15% regular gasoline.
Bobolink has the same email in his inbox starred and ready for comment, and has been wondering what to do with it.
It’s just his luck that James from the Alt-E blog took the words right out of his mouth…
Is Ethanol / E85 Fuel the Solution?

This post tackles frugality, and offers up some simple ways to save some dough:
Cell phones are cool and all–but most people simply shove them in a drawer–or worse–chuck ‘em when they’re finished. In fact, almost 130 million surplus cellphones are created each year in America–weighing in at clost to 65,000 tons! Well, TerraPass has some up with a unique way of solving this problem by partnering up with RIPMobile. From the press release, “RIPMobile recycles used cell phones and PDAs. They also happen to be leaders in their industry for environmental best practices. Unlike many recyclers, RIPMobile will accept any used cell phone, regardless of economic value. They’ll even pay your postage. RIPMobile handles all materials according to EPA standards and in compliance with the stringent requirements of the Basel Action Network.” The great thing about this new partnership is that TerraPass will pay you in gift certificates for your old phones. So, if you’ve been delaying off-setting your SUV with some carbon credits, now’s your chance to kill two birds with one stone! Almost every phone will net you some type of value–from a lowly old Motorola for $2 to a new RAZR for $75. (My expired Samsung came in at $32–not too shabby!). Check it out at TerraPass and–while your’re there–get that car taken care of!
