Eco-Friendly Steam Dishwasher
Washing dishes in a full-loaded dishwasher without pre-rinsing saves water (particularly expensive hot water) over washing by hand. This steam dishwasher designed by Vincent Liew saves even more water and energy!
As the title suggests, this dishwasher uses pressurized steam to dislodge food particles on dishes and sanitize them. A hearty rinse after the cleaning process gives you squeaky clean dishes!
Now for the Eco-friendly part. Since no detergents are used, there is less of “ozone depleting solvents” going around. The water used in the steam and rinsing is collected in the recycling bay and using “Membrane Technology” (read more info on this here), the grime and food particles are separated from the water. The clean water is recycled to be used again for the next wash.
Contaminated water, too harsh for reusing is discarded via an outlet and only then is a fresh load of water consumed.

The Uncanny Future of Electricity
Everyone talks about alternative energy these days but mostly in terms of water, wind and solar. What about cars, cows and tornados?
To meet our future energy requirements, we need to rely on a huge range of alternative sources. Let’s not forget the whimsical beginnings of our efforts to harness electricity (I’m referring to the kite of Benjamin Franklin). It’s only fitting that electricity generation technologies come from left field.

Scientists Set to Ignite a Tiny Man-Made Star
Photo: Lawrence Livermore National Laboratory
Scientist at the National Ignition Facility in Livermore, California, are getting ready to do something spectacular: ignite a tiny man-made star inside a lab and trigger a thermonuclear reaction!
Scientists at the National Ignition Facility (NIF) in Livermore, nestled among the wine-producing vineyards of central California, will use a laser that concentrates 1,000 times the electric generating power of the United States into a billionth of a second.
The result should be an explosion in the 32ft-wide reaction chamber which will produce at least 10 times the amount of energy used to create it.
"We are creating the conditions that exist inside the sun," said Ed Moses, director of the facility. "It is like tapping into the real solar energy as fusion is the source of all energy in the world. It is really exciting physics, but beyond that there are huge social, economic and global problems that it can help to solve."
Inside a structure covering an area the size of three football pitches, a single infrared laser will be sent through almost a mile of lenses, mirrors and amplifiers to create a beam more than 10 billion times more powerful than a household light bulb.
Igniting a tiny man-made star, what could go wrong? Seriously though, this is pretty nifty: Link | National Ignition Facility website | video clip at Wired Science

Electricity-Generating Roadways
Israeli energy company Innowattech has created a new type of road that generates electricity as cars drive on it:
The supercharged surface is embedded with piezoelectric crystals, which transform kinetic energy from passing vehicles into an electrical current. With widespread adoption, the technology could feed energy back into the nation’s burgeoning electric vehicle grid, transforming congested roadways into a clean green source of energy.
The amount of electricity produced isn’t that much (400 kilowatts per kilometer or 645/mi), and there’s no mention on how cost effective it would be. But given the sheer amount of roadways we have (the US has over 4 million miles of roads and streets in its highway system alone), it’s an interesting albeit niche approach to generate electricity.

New Light Glows For 12 Years
Litroenergy is a new type of material that emits light for 12 years without needing electricity or sun exposure. The self-luminous micro-particles are called Litrospheres and are said to be non-toxic, inexpensive and equivalent to a 20 watt incandescent bulb.
The Litrospheres give off a continuous illumination, and can be designed to glow in any color. In addition, they are not affected by heat or cold, and are 5,000-pound crush resistant. They can be injection molded or added to paint. The fill rate of Litroenergy micro particles in plastic injection molding material or paint is about 20%.
The constant light gives off no U.V. rays, and can be designed to emit almost any color of light desired. What a cool product!!
