A recently designed (but old concept) Mini Nuclear Power Plant is now for sale for roughly $25million. The mini-plant is capable of powering 10-20,000 homes and would only need refueling every 7-10 years. On top of that, it has no moving parts, no weapons-grade material, is only a few metres across (the size of a Land Rover), and would be difficult/pointless to steal, as it’s a concrete block, buried underground and when opened the fuel immediatley cools. The potential applications are amazing.
