Meet Mark Suppes, a 34-year-old freelance computer programmer, who built a homemade nuclear fusion reactor in a friends warehouse, in Brooklyn, NY.
The project is legal and not considered dangerous – but people who live near the reactor aren’t convinced.
Some parts of the reactor were purchased on eBay!
The machine is about the size of a filing cabinet. At its center is a core of deuterium atoms that, when heated to 100 million degrees Celsius (about six times hotter than the Sun’s core), should fuse into helium and release a huge amount of safe, clean energy.
The reactor comes in right under $50,000 total cost so far.
