Today, the whole world started to notice the "natural resource" crysis and there has been no perfect solution to get rid of it. There are some traditional and dominating technology - which may prove to be useful if utilised at a massive rate.
Solar energy, wind energy, nano-tech and some un-expected scientific method to generate electricity from virus - can really make the world green -- if utilised properly.
All of the Alternate source of energy have some limitation and benefits, which defines their usability. Solar energy has been widely used since a very long time and a few major companies have adapted it to feed their power hungry machines. It is a clean and unlimited source of energy which can minimize the pollution at a huge scale. The main disadvantage of using solar enegy is - its liquid fuel. Solar panels tends to leak over a small period of time, which makes it less cost efficient.
Researchers at Northwestern University have found one way to stop the leak -- get rid of the liquid used in solar panels. A new variation on the Gratzel Solar cell replaces a short lived organic dye with a solid alternative.
The molecular dye the solid substance replaces was corrosive, at risk of leaking and only lasted about 18-months -- by replacing it, researchers plan to pave the way for a more affordable (and less toxic) alternative.
Northwestern's new design flaunts a 10.2-percent conversion efficiency, the highest ever recorded in a solid-state solar cell of its type -- but that's still only half of what traditional sun collectors can do. Researchers hope to improve conversion in the long run, but expect that the cost reduction alone will be enough to get the party going.
It may not be the greenest solar technology we've ever seen, but who are we to judge?
