Using Solar Power to Extract Oil...

Here is a rather unusual use for Solar Power:

"Chevron disclosed...plans to use...solar thermal technology to enhance oil recovery from an aging well in central California. The system will use 7,000 mirrors on Chevron-owned land to reflect light onto a tower to make steam...The steam will be pumped underground to heat up heavy oils and make them easier to extract. Right now, Chevron uses natural gas to make steam."
