I went to my local Walgreen's today and got a surprise. They had a charging station for electric cars. This was a first for me as I didn't know that we had any set up yet, but had heard of talk about them being installed. All of these are owned by a company called Chargepoint.net and they charge $3 per hour to charge your electric car. While this is a cool idea, I think that when you charge your car at home and have to pay somewhere around 25¢ per KWh the price is a bit steep.I went to my local Walgreen's today and got a surprise.

Patrick Pinhero, an associate professor in the MU (university of Missouri) Chemical Engineering Department, is developing a flexible solar sheet that captures more than 90 percent of available light. Today’s solar panels only collect 20 percent of available light. Prototypes could be produced within the next five years.
The device the team is developing — essentially a thin, moldable sheet of small antennas called nantenna — is designed to harvest industrial waste heat and convert it into usable electricity. Their ambition is to extend this concept to direct solar facing nantenna devices capable of collecting energy broadly from the near infrared to the optical regions of the solar spectrum.
The team, which is seeking funding from the U.S. Department of Energy and private investors, also envisions an energy-harvesting device for existing industrial infrastructure, including solar farms and factories that generate waste heat.
Within five years, the research team believes they will have a product that complements conventional PV solar panels by capturing currently unused infrared energy. Because it’s a flexible film, Pinhero believes it could be incorporated into building materials and infrastructure.
The team envisions several commercial product spin-offs based on the core technology. These include improved contraband-identifying products for airports and the military, optical computing, and infrared line-of-sight telecommunications.

Matrix 3D can use new or recycled paper and using colored paper gets users a color model. The printer laminates the paper and then cuts it with a blade as it builds solid structures one layer at a time. The finished model has a consistency similar to carved wood. Mcor notes that the operating costs of the Matrix 3D are fifty times less than other existing rapid prototype machines.

The video explains it.
But I want to know why I never hear this concept brought up when people talk about the many possible sources of safe, renewable, and envriornmently friendly energy?
The video does not say when the Tower was built though I suspect it has been there for about a decade.
You hear how Solar Panels can only work during the day and that Wind Mills can only work when it's windy.
So why don't you hear about a renewable energy technology that can work a day long?The video explains it.

A team of gearheads at the University of Wisconsin-Madison have developed an engine that can handle a blend of gasoline and diesel fuel. It outputs low emissions, and offers up to 20 percent greater fuel efficiency.
The fuel injection system, called "Fast Response Fuel Blending," mixes the fuels in the combustion chamber to precise proportions. Because the control is so precise, the engine runs at a lower temperature, which means less heat-related energy loss. Also, because the fuel mix is carefully optimized, there's less wasted fuel in the combustion process.
The proportions adjust on the fly according to real-time situations a vehicle faces. Depending on how much weight a truck is carrying and work an engine is putting in, you might see the gasoline-to-diesel ratio vary from 85:15 to 50:50--it really just depends.
Traditionally, the two fuels won't combust when mixed in a diesel engine -- "any attempt to use such a mixture as a motor fuel would be disastrous," says one source -- but the research team says that by controlling the amount and timing of the diesel spray, they can successfully cause combustion.
Team leader Rolf Reitz presented his study at a Department of Energy conference yesterday, and says that they're regularly meeting the EPA 2010 fuel efficiency standards with this blend. He also thinks it could reduce auto-related oil consumption by 33 percent.

People have armchair debates all the time about how realistic it is to get off the grid and totally green, "It's not viable" they say, "impossible". Well this guy has proved them all wrong.
This guy is obviously a one off, but he goes to show that it is totally possible to get these things done. Instead of believing the hype that we need to stay on fossil and other traditional energy sources, open your mind to the possibility of being self-sufficient. If an ordinary person can do this on his own, then there's not a chance on gods green earth that this can't be done on a large scale.People have armchair debates all the time about how realistic it is to get off the... more
