Beacon Power, DOE loan recipient files for bankruptcy

Beacon Power, who makes flywheels for grid storage and load balance, received $43 million in loan guarantees from the government and just filed for bankruptcy.

I’ve followed Beacon for a long time. This loan was comparatively small and doesn’t seem to be stinky or politically connected like Solyndra’s (with its private investors getting debt seniority over the government.)

Dang, Beacon was doing innovative things and has tried hard for years. This will hurt renewable energy even more.
