5 Technologies....Wall Street Journal

Here is the on-line version of the article Keith brought in to class today. My favorite is the algae biofuel technology. "Algae grow fast, consume carbon dioxide and can generate more than 5,000 gallons a year per acre of biofuel, compared with 350 gallons a year for corn-based ethanol."

RE space-based solar power,  I don't want the microwave receiver anywhere near my backyard (even though the microwaves are reportedly safe).

Thanks Keith!
