Helion Energy has been working to make a pulsed commercial nuclear fusion generator 1,000 times smaller, over 500 times cheaper, and realizable 10 times faster than other approaches. Helion Energy received $10.6 million in 2015.
Helion is creating technology it calls “The Fusion Engine,” which would use helium from engine exhaust, according to the company’s website. The helium, along with deuterium fuel from seawater, would be heated to become plasma and then compressed with magnetic fields to reach fusion temperature, which is more than 100 million degrees.
Helion Energy has become quite active on twitter announcing new devices and advances.
They have made a new Turbomolecular pumps.
Turbomolecular pumps like this one let us pump out all the air to 1E-8 Torr (1 Trillionth of an atm!). Rotating at 33,000 rpm, they pump Hydrogen (and Deuterium), operate at high temp, and support continuous fusion operation without regeneration (unlike Cryopumps). #fusionenergy pic.twitter.com/FL2EUX1YNj

Turbo pumps also have a unique feature – the Drop. They operate most efficiently when the gas transitions from fluid flow to molecular flow (individual particles), dropping OoM in seconds. Watch it in action – top is foreline, bottom is chamber pressure. #fusionenergy pic.twitter.com/MuLTuyFBc7

Helion Energy’s research team has discovered that under high voltage (10 kV+), 3-D printed polymers act like very high voltage Zener diodes. Unexpectedly, the printed plastic structure conducts electricity at high voltages, but only in one direction! pic.twitter.com/9i4vxyLKQV
