Cattle industry poised to lead the way to a cooler Earth
In discussing how to counter global warming, it’s pretty easy to argue that nuclear should be the major electricity source and heat producer to replace fossil fuels. At 6 grams per kilowatt-hour, it has the lowest carbon emissions of any energy source, according to the United Nations, and is objectively the safest form of energy for humans and the environment alike, again from a recent UN report.

A low aspect ratio tokamak device has been designed and constructed in University of Tokyo. A cylindrical vacuum vessel is employed. The vessel is divided toroidally into two parts insulated each other. In the vessel, central core composed of ohmic coils and a part of toroidal coils is installed. The aluminum shell is installed to keep the vertical and horizontal equilibrium of the plasma. As the result of several efforts to lower the aspect ratio, the predicted minimum value of the aspect ratio reaches less than 1.2. The predicted advantage of low aspect ratio tokamaks is verified by simulation. The analysis of MHD activities and fluctuations will be carried out, after the assembly is completed.
