Hey, let’s pour water in a volcano and see what happens:
Geothermal energy developers plan to pump 24 million gallons of water into the side of a dormant volcano in central Oregon this summer to demonstrate technology they hope will give a boost to a green energy sector that has yet to live up to its promise.
They hope the water comes back to the surface fast enough and hot enough to create cheap, clean electricity that isn’t dependent on sunny skies or stiff breezes — without shaking the earth and rattling the nerves of nearby residents.
Renewable energy has been held back by cheap natural gas, weak demand for power and lack of political concern over global warming. Efforts to use the earth’s heat to generate power, known as geothermal energy, have been further hampered by technical problems and worries that tapping it can cause earthquakes.
Even so, the federal government, Google and other investors are interested enough to bet $43 million on the Oregon project.
The rest here.
