Kaleidos produces a portable nuclear microreactor that replaces diesel generators. It is a compact nuclear reactor (1 MW) with all the necessary equipment to generate electricity for remote villages and facilities, as well as backup power for hospitals and data centers. It requires no on-site water consumption thanks to the use of fans for air cooling. Helium conducts heat away from the core and does not become radioactive, eliminating the impact of leaks. Meltdown-resistant TRISO fuel, consisting of uranium particles coated with a ceramic coating, has been used in more than 30 grid-scale reactors since the 1960s. The reactor is assembled and fueled at the factory and delivered by truck or plane. Kaleidos mass-produces microreactors for US military bases.

Antares designs and builds microfission reactors for strategic energy applications, including space missions, commercial and military energy resilience. The R1 microreactor can produce from 100 kilowatts to 1 megawatt and uses TRISO fuel, which consists of uranium spheres coated with carbon and ceramics, embedded in graphite. The company performs high-precision machining of the nuclear graphite in-house, speeding design iterations. The optimized reactor design simplifies deployment with a minimal number of actuators. The control drums, made of graphite and boron carbide, have independent actuators, inspired by the designs of historical space reactors. Antares has a manufacturing facility in California and has already tested the first electrically heated demonstration unit (EDU).

Aetherflux is building a constellation of small LEO satellites to beam solar energy to Earth using infrared lasers. This approach differs from traditional space-based solar power (SBSP) concepts, which rely on massive geostationary platforms transmitting power via microwaves. The US Defense Department has allocated funding for the development of this technology to ensure the energy supply to remote military bases and contested areas. Additionally, the Aetherflux satellites will have an orbital computing node that utilizes continuous solar power and radiative cooling to enable high-performance data processing in space. The node uses optical inter-satellite links and advanced relay networks to ensure continuous availability, consistent with ground-based application servers.
