Physicist Seeks Alternative Fuels

 Forum Introduction
Steven Chu Nobel Prize-winning physicist Steven Chu is leading the Lawrence Berkeley National Laboratory's efforts to develop cleaner forms of energy, including new types of solar cells and new biofuels. He answered viewer questions about his research and the future of alternative fuels.
QUESTIONS
Do you believe we will find technology to reverse global warming?
Will "paint-on" photovoltaics be available soon?
What about developing technology to remove existing carbon dioxide from the atmosphere?
How will biofuel production affect our water supply?
Is enough being done to ensure that biofuels help the environment more than hurt it?
What's more important in advancing alternative fuel use, individual lifestyle changes or national policy?
Do you question the ethics or motives of your laboratory's funders?
What about conservation?
Can I run my car on salad oil?
Should we be partnering with researchers in other countries to solve our energy problems?
Julie Rotherham of Charlottesville, Va. asks:
How important is it for people to buy flourescent lights, drive hybrid cars, and take individual steps? Should grassroots efforts be focused on the individual or on national issues to find alternative fuels? Where should I send my donation dollars?
ANSWERS
Steven Chu responds:

All of these things are important. Also, you should let your congressional representative know that an electricity bill that is 10 to 20 percent higher than present is a small price to pay for saving the planet.
