AltaRock is the developer and manufacturer of geothermal systems for baseload power generation. Their technology taps into the stores of very high-temperature heat deep in the earth's crust to yield up to 10 times more energy than a conventional geothermal well. They seek to develop the technologies required to massively scale these systems around the world. AltaRock is currently headquartered in Seattle, WA. It was founded in 2007 by Susan Petty.
