Your cellphone has 10 sensors, and your car has 400. But your body has none - that's going to change.

Not thinking it's possible is a failure of imagination.

It doesn't matter what your probability of failure is. If there's a 90% chance of failure, there's a 10% chance of changing the world.

For electric power generation, we are very optimistic about solar-thermal technology, and we’re intrigued by the potential of enhanced geothermal energy to replace coal-based power generation. Traditional carbon capture and sequestration-based coal power generation is somewhat unlikely to be competitive.

Certain food-based biofuels like biodiesel have always been a bad idea. Others like corn ethanol have served a useful purpose and essentially are obsoleting themselves.

Now it will take a long time to scale biofuels, but I'm the only one in the world forecasting oil dropping in price to $35 a barrel by 2030. I'll put it on the record: Oil will not be able to compete with cellulosic biofuels. If you do it from food, the food will get so expensive you can't make fuel out of it.

The U.S. has fallen well behind Europe in recognizing climate change and the implications of climate change.
