First Light claims to have achieved fusion energy by shooting a projectile at a fuel target for four miles a second and releasing energy.
First Light Chairman Bart Markus said in a statement that they have identified a genuine route to commercial fusion.
The company claims to have demonstrated its approach by fusion atoms using its device, but has yet to achieve the ultimate goal of harvesting more energy from fusion than was needed to start the reaction.
Most scientists working on the problem have decided to heat the plasma to extreme temperatures, around ten times the temperature of the Sun, to bind atoms together in a process that can release a lot of energy inside a huge, donut-shaped reactor.
Scientists at the UK-based Joint European Torus (JET) lab broke their own 25-year-old record earlier this year, producing 59 megajoules of energy over five seconds.
The Big Friendly Gun is a device that shoots small projectiles at small fuel targets at ten times the speed of your average rifle bullet.
The targets could be made for $10 to $20 each, according to First Light.
The CEO of the company told the Financial Times last year that it was the ultimate espresso capsule.
The company claims that it could be enough to power an average UK home for two years.
This pursuit of practical and affordable fusion will give us the clean and abundant baseload power that we desperately need in our effort to address global warming.
The proof is in the pudding, or in this case, tiny packets of deuterium.
The UK start-up achieved a breakthrough.
There are amazing video shows inside the fusion reactor.
