China designs nuclear reactor without cooling water
A molten salt nuclear reactor that uses thorium instead of uranium could be built in the desert and provide electricity for 100,000 people.
The first nuclear reactor uses new fuel
India is planning to build a nuclear power plant using new materials, thorium, which has a low radioactivity, safer than using uranium.
Technology can provide enough energy for humans for billions of years
Cold War-era molten nuclear reactor technology has been proven to be used to create clean, sustainable and safe energy for Earth for tens of billions of years.
