High-power facilities able to deliver into the load tens megaampers of current for microseconds are applied now world wide to solve a whole set of scientific and applied issues. Now more and more energy and power are required from these facilities. By now several stationary machines have been created such as Pegasus-II with the energy more than 1 MJ, Shiva-Star up to 9 MJ, new Atlas facility for 25 MJ is in the process of construction and the idea of creating Jupiter for 100 MJ. Large experience in creation of single action explosive magnetic generators - EMG has been accumulated. VNIIEF has created EMG which can deliver more than 200 MA of current into the load with the full magnetic energy more than 100 MJ. Stationary facilities are more expensive than EMG, but they enable many experiments to be conducted, because the cost of one shot with a stationary machine is less than EMG cost. However, with the increase of energy, released in one shot on a stationary machine the cost of disposable elements increases, so the cost for one shot increases faster than the energy increases. It is estimated that if the energy of a shot is about 100 MJ this is equivalent to the explosion of about 25 kg of trotyl, the cost of one shot may exceed the cost of EMG. That is why the use of high-energy EMG is very reasonable not only because the stationary facilities of required energy and power have not been yet created, but for the purpose of saving money now and in future.
