Is this the future of energy? Lockheed Martin's Compact Fusion Reactor packs the power of the sun into a truck-sized device.

A Return to the Atomic Age

Lockheed Martin has released details on a pint-sized fusion reactor that could one day power just about everything.

So far, the efforts to feed our seemingly insatiable appetite for energy have all been massive operations – windmill farms towering across the countryside, solar arrays the size of football fields, nuclear and coal plants lurking at cities' edges.

But a new project coming out of the Skunk Works team at Lockheed Martin (IW 500/30) is taking a different approach. A radically different approach.

Today, the team announced progress made on a compact fusion reactor (CFR) that packs the same power capacity of those large-scale systems into a device small enough to fit on the back of truck.

Potential applications for the device are endless – from interplanetary spacecraft and city power stations to nuclear-powered aircraft that can fly practically forever without refueling.

If it works out, it could basically answer all of our global power needs and effectively end our dependence on fossil fuels. It has already been called the "holy grail" energy breakthrough we've been waiting for.

Those are all big claims, of course, but after 60 years of work, this project is suddenly starting to seem like a pretty big deal.

CFR Details

Basically, the CFR is straight out of a comic book villain's lab.

It uses a system of high-powered electromagnets to hold together a mass of plasma reaching millions of degrees, roiling at the heart of the device.

There, superheated deuterium (produced from sea water) and tritium (derived from simple lithium) fuse together, producing energy 100 times more powerful than chemical reactions and three-to-four times stronger than the fusion reactions that drive our current nuclear power facilities.

It is basically a pint-sized steel sun that (once completed) will be ready to power our cities, power our ships and planes, charge our cars and light our homes.

The fuel is said to be effectively inexhaustible and its waste deemed safe after just 100 years (a heartbeat compared to what fission reactors throw off).

A viable prototype of the CFR is still about five years away, Lockheed researchers say, and the devices are still probably a decade from actual deployment.

But with the technological breakthrough this project represents, that timeline seems almost frighteningly fast.
