The new Thorizon startup wants to make a 100 MW molten salt reactor that uses a mixture of nuclear waste and thorium as fuel. Those kinds of small nuclear reactors are interesting tools because they offer the possibility of recycling nuclear waste. That makes the nuclear fuel cycle more effective. However, those systems also offer the possibility of creating new, non centralized energy production solutions. 

Those systems are not so vulnerable to strikes. That thing increases national security. Another reason the small miniature nuclear reactors are under development is the increasing need for electricity. New data centers require effective energy solutions. And things like directed energy weapons DEWs require confirmed high-power energy production. Microwaves and lasers are the most effective weapons against drones and drone swarms. As well as against stealth aircraft. 

The microwave system can create microwave fields around targets. Those high-power microwaves can have the purpose of heating the drone's and aircraft's bodies. Those systems can cause material damage and that can turn fatal. The system denies its aircraft operations in those areas. And they can have a very bad effect on the birds that go in those microwave fields. The megawatt-class microwaves require lots of energy. Miniature nuclear plants can also offer that power supply.

The futuristic power unit can use a radioisotope thermoelectric generator, RTG, or RITEG systems for energy supply. The system can look like a normal nuclear reactor. But there is a series-, and side-by-side connected RTG systems. The RTG also offers the possibility to offer independent energy production for every calculation- or central unit. 

Another thing that offers interesting energy use is a radioisotope thermoelectric generator, RTG, or RITEG. The RTG is a normal electric battery. Except its energy comes from nuclear isotopic decay. The kind of batteries used in the Voyager space probes. The RTG systems can be connected side by side. Or into a series and those systems can offer electricity for a very long time. 

The Voyager spacecraft was sent on its journey in the year 1977. And it still works. So RTG technology can offer an energy solution that stands, for at least, almost 50 years. That kind of system can look like the nuclear reactors, but there is a series and side-by-side connected RTG systems. That kind of system is also interesting to give energy to many other systems. Like small nuclear submarines and portable laser and radar systems.
