Bill Gates 2, Innovating to zero! (script)
Summary
This was a long talk. There are lots of problems which we have to solve in our world there. It's too many and too difficult to summarize.
What is innovating to zero?
The speaker Bill Gates was a parson who performed exactly a miracle about computers we use now. His current activity is to help the poorest two billion live better lives. When he thought of it, he realized that for reducing poverty, energy is very important. They can't use it enough. However, now people in the world use it too much. It leads to climate change. It'll make them become poorer, because their crops won't grow. However, using it is not able to stop.
All energy can't change the renewable sources, because the sun doesn't shine and the wind doesn't blow every day. It leads to the price of energy has come up. It'll again send them poorer. He had reached the conclusion which is to zero now releasing CO2.  We have to use miracle which is innovation to zero again like our computers. This time, there is a limitation.
And then, he surprisingly hope to proceed the idea of TerraPower. It's because 1) just using nuclear is usually costly. 2) Above all, it doesn't release CO2.  3) This crazy idea can solve the problem that is about the waste of nuclear. He also said that you have to think of our problems as long team one, because here are many things that we can't solve for short term. The now skeptics probably pay for the mistakes a lot later.
However, the talk was told before 2011. 2011 is the year when the big nuclear accident occurred in Japan. Thus, I think that it should be strongly proceeded. Probably he also thinks that, but the world will be put in a more difficult situation.
In this TED talk, he introduced some speakers.
