GE Announces Breakthrough For Low-Cost Organic LED Production
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,
Electronic Tattoo Display Draws Energy From Your Blood
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.
Cutting Down on Cooking Costs: Green SAHM’s Got Some Tips
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!

Green Ideas We’d Like To See: The Electric Super Tipper Truck
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.
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,
New Eco-Friendly Washing Machine Takes Only 14 Minutes To Get The Job Done
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.
Smaller, Smarter Inverters Equal Cheaper Solar, Greater Efficiency
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,
The Venturi Astrolabe: A Street-Legal Formula One Solar Car
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.”

The PowerLeap: Harnessing Human Energy With Floor Tiles
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.
Electric drag racer
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.
