Nuclear fusion is coming, says noted VC Wal van Lierop:
Chrysalix’s optimism is pinned on an angel investment the company made in General Fusion, a Canadian company that says it has found a way to hurdle many of the technical problems surrounding fusion. The company’s ultimate plan is to build small fusion reactors that can produce around 100 megawatts of power. The plants would cost around $50 million. That could allow the company to generate electricity at about 4 cents per kilowatt hour, making it competitive with conventional electricity.The company uses a technique called Magnetized Target Fusion (MTF) model. In this scenario, an electric current is generated in a conductive cavity containing lithium and a plasma. The electric current produces a magnetic field and the cavity is collapsed, which results in a massive temperature spike.
The lithium breaks down into helium and tritium. Tritium, an unstable form of hydrogen, is separated and then mixed with deuterium, another form of hydrogen. The two fuse and make helium, a reaction that releases energy that can be harvested. So in short, lithium, a fairly inexpensive and plentiful metal, gets converted to helium in a reaction that generates lots of power and leaves only a harmless gas as a byproduct. MTF has an advantage over other fusion techniques in that the plasma only has to stay at thermonuclear temperatures (150 million degrees Celsius) for a microsecond for a reaction to occur, according to the General Fusion’s Web site. General Fusion has also filed for several patents.
