222 examples of Fusion in a sentence
This is rather warm, and this is why
fusion
is so hard to do.
Now, I caught my little
fusion
bug when I did my Ph.D. here at the University of British Columbia, and then I got a big job in a laser printer place making printing for the printing industry.
But I've decided to get my bit to solve global warming and make
fusion
happen.
Now, so the first thing I did is I looked into the literature and I see, how does
fusion
work?
So the physicists have been working on
fusion
for a while, and one of the ways they do it is with something called a tokamak.
Then they throw a huge amount of heat in there to try to cook that to
fusion
temperature.
So this is the inside of one of those donuts, and on the right side you can see the
fusion
plasma in there.
Now, a second way of doing this is by using laser
fusion.
Now in laser fusion, you have a little ping pong ball, you put the
fusion
fuel in the center, and you zap that with a whole bunch of laser around it.
And if you squeeze something hard enough, it gets hotter, and if it gets really, really fast, and they do that in one billionth of a second, it makes enough energy and enough heat to make
fusion.
Now, most people think that
fusion
is going nowhere.
This is a curve of the gain in
fusion
over the last 30 years or so, and you can see that we're making now about 10,000 times more
fusion
than we used to when we started.
It's a big tokamak donut in Europe, and this machine in 1997 produced 16 megawatts of
fusion
power with 17 megawatts of heat.
It's a big laser machine in the U.S., and last month they announced with quite a bit of noise that they had managed to make more
fusion
energy from the
fusion
than the energy that they put in the center of the ping pong ball.
So this is a big collaboration of different countries that are building a huge magnetic donut in the south of France, and this machine, when it's finished, will produce 500 megawatts of
fusion
power with only 50 megawatts to make it.
Actually, the science to make those machines was really in time to produce
fusion
during that curve.
Now,
fusion
is often criticized for being a little too expensive.
Now, we spend one half of a percent of that on
fusion.
Now I can say that, but I'm a little bit biased, because I started a
fusion
company and I don't even have a Facebook account.
So when I started this
fusion
company in 2002, I knew I couldn't fight with the big lads.
Now magnetic and laser
fusion
are pretty good machines.
They are awesome pieces of technology, wonderful machines, and they have shown that
fusion
can be done.
They're way too big, way too complicated, way too expensive, and also, they don't deal very much with the
fusion
energy.
When you make fusion, the energy comes out as neutrons, fast neutrons comes out of the plasma.
So back to the literature, and I read about the
fusion
everywhere.
One way in particular attracted my attention, and it's called magnetized target fusion, or MTF for short.
And then you have some pistons driven by pressure that goes on the outside, and this compresses the liquid metal around the plasma, and it compresses it, it gets hotter, like a laser, and then it makes
fusion.
So it's a bit of a mix between a magnetized
fusion
and the laser
fusion.
And finally, all the energy to make the
fusion
happen comes from steam-powered pistons, which is way cheaper than lasers or superconducting coils.
So finally, most people think that
fusion
is in the future and will never happen, but as a matter of fact,
fusion
is getting very close.
