Could The World Be Powered By Lasers? Dyson sphere. Dyson sphere is a hypothetical megastructure that completely encompasses a star and hence captures most or all of its power output.
It was first described by Freeman Dyson. Dyson speculated that such structures would be the logical consequence of the long-term survival and escalating energy needs of a technological civilization, and proposed that searching for evidence of the existence of such structures might lead to the detection of advanced intelligent extraterrestrial life. Gaia. Deep ecology. Earth Paradigm. A Virus That Creates Electricity. A virus called simply M13 has the power (literally) to change the world.
A team of scientists at the Berkeley Lab have genetically engineered M13 viruses to emit enough electricity to power a small LED screen. M13 poses no threat to humans — it can only infect bacteria — but it could one day serve humanity by powering your laptop, or even your city. The secret of M13 lies in something called the “piezoelectric effect,” which happens when certain materials like crystals (or viruses) emit a small amount of power when squeezed. M13 exhibits this effect, and also has the handy ability to organize itself into tidy, invisible sheets of film. Imagine painting a layer of this film onto the casing for your laptop.
