Solar Power For Humanity

By Anupum Pant

This is a solar collector developed by the engineers at IBM which you could call a concentrated solar collector. It consists of a huge mirror for concentrating sun onto a semiconductor chip and can convert it to electricity. Of course solar panels do the same, but this one can sustain the deathray and make an extremely high power density source. So much that if 2% of the sahara gets covered by this device, it could power the whole humanity (2% of sahara BTW is 188,000 kmĀ²).

Also, the device produces intense heat which can melt the semiconductor chip. So it has to be cooled. The water which is used to cool it takes away the heat and this energy is used to desalinate water. And that’s just the by-product of this awesome device.
