Nuclear pulse propulsion was the subject of Project Orion. One of the more explored concepts is the nuclear thermal rocket, which was ground tested in the NERVA program. Įxamples of concepts that use nuclear power for space propulsion systems include the nuclear electric rocket (nuclear powered ion thruster(s)), the radioisotope rocket, and radioisotope electric propulsion (REP). The more powerful TOPAZ-II reactor produced 10 kilowatts of electricity. Īfter a ground-based test of the experimental 1965 Romashka reactor, which used uranium and direct thermoelectric conversion to electricity, the USSR sent about 40 nuclear-electric satellites into space, mostly powered by the BES-5 reactor. The United States tested the SNAP-10A nuclear reactor in space for 43 days in 1965, with the next test of a nuclear reactor power system intended for space use occurring on 13 September 2012 with the Demonstration Using Flattop Fission (DUFF) test of the Kilopower reactor. A radioisotope heater unit is powered by radioactive decay and can keep components from becoming too cold to function, potentially over a span of decades. Small fission reactors for Earth observation satellites, such as the TOPAZ nuclear reactor, have also been flown. The most common type is a radioisotope thermoelectric generator, which has been used on many space probes and on crewed lunar missions. Another use is for scientific observation, as in a Mössbauer spectrometer. Nuclear power in space is the use of nuclear power in outer space, typically either small fission systems or radioactive decay for electricity or heat. White RTG with fins is visible at far side of rover. If nothing else, $3,000 could buy you a lifetime supply of “nice purple light.Mars Curiosity rover powered by a RTG on Mars. The student also says the setup’s electrical transformer shouldn’t be left on for more than 20 minutes, meaning your window to begin producing neutrons is quite brief. This is required to start any potential nuclear reaction, and is also a $50 value, but yours with the price of purchase of the plasma generator. The student included 20 grams of deuterium oxide-heavy water-with the purchase of the plasma generator. If he’d made the $3,000 he was asking as a starting bid, that would have paid for well over half of an average New Zealand college education’s tuition cost, which is just over $4,000. So our unnamed Kiwi salesperson is the latest in a legacy of illustrious young nuclear engineers, but he seems to be the first to try to sell the results of his experiment. Wilson, now 25, spent his teen and young adult life designing innovative, low-cost versions of technologies like molten salt reactors and radiation detectors. But Wilson had his parents’s blessing and support, and he worked safely. Wilson was just 14, and he was motivated by how costly it is for people to receive nuclear medicine treatments. More recently, we learned about Taylor Wilson, who in 2015 was “one of only 32 people to build a nuclear fusion reactor themselves,” National Geographic reported. ![]() This Powder-Not Gas-Could Rescue Nuclear Fusion.The Tiny Nuclear Reactor That Could Change Energy. ![]() The Navy May Have a Working Compact Fusion Reactor.“The purpose of the reactor currently is just to make nice purple light, the potential for the reactor is to produce neutrons for other projects,” he says. “The next step is for a very brave person to start a nuclear reaction with the deuterium and some silver,” he wrote in the now-closed listing.įor the low low price of $3,000, a buyer in New Zealand would receive “a beautiful plasma generator” that “has been completed by a qualified electrical engineer.” The student made the generator for a science fair project. He also says the plasma reactor could be brought online by an intrepid amateur scientist. The young man says his goal was to raise money for his tuition. The student is the latest in a legacy of young people building nuclear reactors in their backyards or schools.Ī college student in New Zealand tried to sell a “potential” nuclear reactor on a local version of Craigslist.Most plasma fusion research is getting grander and more ambitious, but you can't buy that on Craigslist.This student's "nice purple light" could become a nuclear reactor if you add heavy water and silver.
