This
is an invention that might possibly modify the civilization as we know it: A
compact fusion reactor presented by Skunk Works, the stealth experimental
technology section of Lockheed Martin. It's about the size of a jet engine and
it can power airplanes, most likely spaceships, and cities. Skunk Works state
that it will be operational in 10 years.
Aviation
Week had complete access to their stealthy workshops and spoke to Dr. Thomas
McGuire, the leader of Skunk Work's Revolutionary Technology section. And
ground-breaking it is, certainly: Instead of utilizing the similar strategy
that everyone else is using— the Soviet-derived tokamak, a torus in which
magnetic fields limit the fusion reaction with an enormous energy cost and thus
tiny energy production abilities—Skunk Works' Compact Fusion Reactor has a
fundamentally different methodology to anything people have tried before. Here
are the two of those techniques for contrast:
The
old-style Soviet tokamak scheme of the International Thermonuclear Experimental
Reactor, a huge system being constructed in France.
The
crucial point in the Skunk Works arrangement is their tube-like design, which
permits them to avoid one of the boundaries of usual fusion reactor designs,
which are very restricted in the sum of plasma they can sustain, which makes
them giant in size—like the gigantic International Thermonuclear Experimental Reactor.
According to McGuire:
“The traditional tokamak designs can only hold so much plasma, and we call that the beta limit. Their plasma ratio is 5% or so of the confining pressure. We should be able to go to 100% or beyond.”
The Skunk Works' recent compact fusion reactor design.
This
design lets it to be 10 times smaller at the same power output of somewhat like
the ITER, which is anticipated to produce 500 MW in the 2020s. This is
essential for the use of fusion in all kind of uses, not only in huge, costly
power plants. Skunk Works is committed that their structure—which will be only
the size of a jet engine—will be capable enough to power almost everything,
from spacecraft to airplanes to vessels—and obviously scale up to a much bigger
size. McGuire also claims that at the size of the ITER, it will be able to
produce 10 times more energy.
The
one thing here to remind everyone is that Lockheed Martin is not a stupid dude
working in a garage. It's one of the world's major aerospace and military
corporations. McGuire also understands that they are just starting now, but he
says that the architecture of this compact fusion reactor is sound and they
will progress rapidly until its final operation in just a decade:
“We would like to get to a prototype in five generations. If we can meet our plan of doing a design-build-test generation every year, that will put us at about five years, and we've already shown we can do that in the lab. So it wouldn't be at full power, like a working concept reactor, but basically just showing that all the physics works.”
After
five years, they believe to have a completely operative model prepared to go
into full-scale construction, capable of producing 100MW— which is enough to
power a huge cargo ship or an 80,000-home city—and its size will be 23 x 42
feet only which is quite amazing.
It's a Stellerator.
ReplyDeleteIt would be cheaper and easier if 'we' built Advanced Design Fission Reactors and Molten Salt Thorium Reactors to take us thru the next 40 years until Fusion reactors can be perfected. That, along with Renewable energy resources, would finally get us off of coal, oil and Natural gas.
ReplyDeleteThat's what I was thinking as reading this. Ditto William.
Deletecould you specify which "advanced" design you mean, because if I wiki "Advanced Design Fission Reactor" I get many types. I would like to read up on this subject. Thanks.
