Overview
The impending consequences of the earth's dwindling water supply are no mystery. The question that we all need answered, however, is how to replenish it. French physicist Jérôme Kasparian, may have a solution with his new seeding condensation method.
'Laser-assisted water condensation' is a water-collecting technique which employs powerful lasers. At the flip of a switch, a laser pulse carries trillions of watts of energy into the atmosphere, removing electrons from atmospheric molecules. The removal of electrons creates charged particles, which form water droplets as more and more water molecules accumulate and stick to the original particle.
Kasparian's method seems a good alternative to other current precipitation-inducing techniques, which are expensive, risky, and environmentally damaging. It isn't a magical cure-all to drought and drinking water shortages, but it is definitely a step in the right direction.
