First US Solar Power Tower

Idealab rebounds with recent focus on clean technology - Los Angeles Times



The hundreds of glass mirrors break the dusty field in Lancaster, a sea of silver in a landscape of brown.

When switched on for the first time today at an opening gala with investors, local politicians and others, they'll make up the first operational solar tower energy facility in the United States.

They reflect the sun into a tower in the middle of the field, boiling water into steam that travels through pipes to power a turbine and create electricity. The plant, created by Pasadena company ESolar Inc., will be able to power 4,000 homes.

Global Warming No, Earthquakes Yes

[T]he new project [near San Francisco] will tap geothermal energy by fracturing hard rock more than two miles deep to extract its heat. AltaRock, founded by Susan Petty, a veteran geothermal researcher, has secured more than $36 million from the Energy Department, several large venture-capital firms, including Kleiner Perkins Caufield & Byers, and Google. AltaRock maintains that it will steer clear of large faults and that it can operate safely.

But in a report on seismic impact that AltaRock was required to file, the company failed to mention that the Basel [Switzerland] program was shut down because of the earthquake it caused. AltaRock claimed it was uncertain that the project had caused the quake, even though Swiss government seismologists and officials on the Basel project agreed that it did. Nor did AltaRock mention the thousands of smaller earthquakes induced by the Basel project that continued for months after it shut down.

The California project is the first of dozens that could be operating in the United States in the next several years, driven by a push to cut emissions of heat-trapping gases and the Obama administration’s support for renewable energy.
