Bill Gross 1 : A solar energy system that tracks the sun (transcript)

Summary

The speaker said that he got interested in solar energy when he was 15 years old. He has known about an energy crisis and worked for it from over three decades ago. It led to solar systems.

And then, solar systems are, now, gradually becoming a fact. Converting solar energy was a very practical cost though it took a long time to store, it had to store more to use on cloudy days and another problem appeared.

That was about us. Even if new energy is invited, we can't save our earth from energy crisis if our habits are not changed. We have been indifferent to using all energy anytime and anywhere. Oil is also solar energy concentrate. It took a lot of time to make it though we consume it at incredible speed. We still have to create usage renewable energy at the same pace when we’re using the energy. We don't have time to make usual one yet.

P.S. This story leads to next his TED talk. He said that he had big detour though I didn't think so.
