This may seem to be a bit way out for this field of engineering but there might be some mileage in considering the method. Norton Motorcycle company produced a very fast racing machine in the fifties

Really, the cooling of the tank circuit can be done numerous ways. However, amateur equipment manufacturers look at the cost. They want to build an amp that they can get the most out of with the less

Dear Traian, Breeder-type reactors especially use liquid sodium cooling in the primary circuit. The problem found was that under severe neutron flux, the sodium metal became itself radioactive and th
