As described above, the energy efficiency η 1 depends on the value of the parameter P of the electric circuit. For example, when P=0.4, the energy efficiency η 1 is calculated to be 56.7% by the above equations 8, 9 and 10. Accordingly, when P=0.4, concrete is crushed while the energy (electric power) stored in the circuit is reduced by 56.7%.
