Google, one of the first few companies to see its top management drive hybrid vehicles to set a good example to the rest of the world, continues with their green binge by investing $168 million in the construction of a new solar power tower. This tower is being developed by BrightSource Energy in the Mojave Desert, where it is tipped to generate 392 MW of solar energy. Also known as the Ivanpah Solar Electric Generating System (ISEGS), this project can be said to be famous for its structure. While solar power towers do work in theory, they are far and few in between in the US, as the technology requires the use of field mirrors to concentrate the sun’s rays on a receiver that is located on top of a tower. The receiver will then generate steam, spinning wildly to create electricity in the process. This solar power tower is tipped to be completed when the year 2013 rolls around. Hopefully concentration of the sun’s rays will also be able to zap aliens out of the sky while they’re at it.
