Avalanche Energy

Avalanche received a $275K grant from the National Science Foundation (NSF) to study the efficiency of its Orbitron fusion device.

Avalanche says its compact fusion machine has a core small enough to hold in one’s hands and could fit in a pickup bed when fully integrated. The page contrasts this with the large cores and infrastructure common to other fusion efforts.

Avalanche Energy says it is working toward making the next generation of space exploration a reality.

Avalanche is a Seattle-based start-up developing enormously energy-dense compact fusion machines for clean power generation.

The company says humanity’s future demands power that moves with people, scales quickly, and reaches land, sea, and space.

Seattle-based Avalanche Energy reports that its desktop fusion machine operated for hours while maintaining 300,000 volts. The company describes the sustained operation as a key milestone on the path toward a desktop fusion reactor.

Avalanche Energy operates its desktop fusion machine for hours while maintaining 300,000 volts, a milestone the startup says advances its effort to build a compact fusion reactor. Its design uses electrical currents to pull ions into tight orbits around an electrode, where collisions can produce fusion; the company targets reactors from 5 kilowatts to several hundred kilowatts. Washington State awards Avalanche $10 million to build FusionWERX, a testing facility for fusion companies and researchers.
