As you all know, when I was young I did think of some astonishing ways (Here and Here) in which alternate energy could be harnessed. I was well in the course of redefining what alternate energy was, but the exams took over my life!
This article is another brilliant idea in the same direction. I guess you all know about Solar energy and Solar panels. For the information, Solar panels convert light into electrical energy.
On one May afternoon in Chennai when I was young, I casually opened the tap water to wash my hands. I couldn’t keep my hands for more than two seconds in that flowing water – it was so hot!! Ok, this happens every summer.
Me being me, who sees an opportunity in every adversary, came up with this startling idea. While the westerners were busy converting light in to energy (which is what they have), why not convert heat from sun, into energy? (which we have in abundance).
So, basically what I am doing is – I am converting water in to steam, using the heat from sun. This set up includes a hemispherical transparent (thin) glass kept at the terrace, which contains some water.
The glass should be thin enough that most of the sunlight and heat can pass through it, but steam generated from the heated water below cannot pass through. There can also be reflective mirrors all around this hemispherical glass, that could concentrate more heat from outside into the water. And besides, glass does not allow heat to go out easily (remember green house effect?)
The generated steam could be used to generate electricity by some means. So, what do you people think? Is it feasible?
PS: The photovoltaic cells on the solar panels convert light into electricity. It would be good if they find out some element that could directly convert heat into electricity to avoid the complicated procedure mentioned above.
