Can you store solar energy in rust and water
What if you could run a car on only yard clippings and expired diet soda?
What if you could capture the energy of the sun in scarpe hogan donna outlet rust and then convert it scarpe hogan outlet donna to hydrogen?
As oil becomes more expensive and the environmental aspects of mining processes like fracking are tiffany e co challenged, the race to find inexpensive louboutin and clean energy is on. Sometimes the energy brainstorming gets a little crazy (like that first idea, which you should feel free to try out). The latter idea, however, isn't the dazed thought of nike tn officiel a mad scientist. It's actually the very rational louboutin chaussures process of some extremely intelligent and decidedly sane scientists. Better yet, they did it cheaply.
The idea of creating hydrogen from solar energy has actually been around for a while. Scientists from Ecole polytechnique fdrale de Lausanne (EPFL) in Switzerland originally found a hogan outlet sito ufficiale way to produce hydrogen from just water in the 1990s. While it sounds like busting up water molecules and turning them into hydrogen and oxygen would be a mess air max pas cher of scientific jargon, it's actually pretty easy nike tn to understand. Essentially, it's just using a semiconductor that creates scarpe hogan online the reaction to generate oxygen and a solar cell that then frees the hydrogen. And, of course, we can't forget the all important electrons. tiffany outlet negozio Or the light. air max 90 pas cher (Don't worry, we'll go into that more on the next page.)
As we've said, the Swiss contingent had already giuseppe zanotti sneakers pas cher successfully managed this process two decades ago. But in 2012, they gave themselves barbour femme soldes the challenge of doing it without extremely expensive equipment. team managed to make a similar product that air max pas cher pour femme produced a chaussure louboutin pas cher 12.4 percent efficiency a big number, as it means that they were able to convert 12.4 percent of the solar scarpe hogan online originali light into hydrogen. Unfortunately, the product translated to a gasp inducing $10,000 per 10 tiffany sito ufficiale square centimeters surface cost [source: louboutin pas cher femme Pousaz]. Not exactly competitive consumer pricing.
So why in the world do the scientists optimistically predict they can create a chaussure nike tn pas cher 10 percent efficiency prototype at a cost of $80 per square meter [source: Pousaz]?
