From the Ted Talk by Michel Laberge: How synchronized hammer strikes could generate nuclear fusion

Unscramble the Blue Letters

Now we know of two ways of making nuclear energy: fission and fusion. Now in fission, you take a big nucleus, you break it in part, in two, and it makes lots of eergny, and this is how the nuclear reactor today works. It works prttey good. And then there's fusion. Now, I like fusion. Fusion's much better. So you take two small nuclei, you put it together, and you make helium, and that's very nice. It makes lots of energy. This is nature's way of producing energy. The sun and all the satrs in the universe run on fusion. Now, a fusion plant would actually be quite cost-effective and it also would be quite safe. It only produces srhot term radioactive waste, and it cannot melt down. Now, the fuel from fusion comes from the oacen. In the ocean, you can extract the fuel for about one thousandth of a cent per kilowatt-hour, so that's very, very chaep. And if the whole planet would run on fusion, we could extract the fuel from the ocean. It would run for billions and bnloilis of years.

Now we know of two ways of making nuclear energy: fission and fusion. Now in fission, you take a big nucleus, you break it in part, in two, and it makes lots of energy, and this is how the nuclear reactor today works. It works pretty good. And then there's fusion. Now, I like fusion. Fusion's much better. So you take two small nuclei, you put it together, and you make helium, and that's very nice. It makes lots of energy. This is nature's way of producing energy. The sun and all the stars in the universe run on fusion. Now, a fusion plant would actually be quite cost-effective and it also would be quite safe. It only produces short term radioactive waste, and it cannot melt down. Now, the fuel from fusion comes from the ocean. In the ocean, you can extract the fuel for about one thousandth of a cent per kilowatt-hour, so that's very, very cheap. And if the whole planet would run on fusion, we could extract the fuel from the ocean. It would run for billions and billions of years.
