Broadband infrastructure is generally efficient, but it fails to function in catastrophic
situation such as earthquake, typhoon and so on. Therefore, local power supply based on renewable energy is important. However, the energy is unstable and changeable and it is difficult to meet supply and demand. The present authors addressed effective lifting because it is necessary to store unstable energy in pumped hydropower. In this re p ort, water model experiments on Archimedean screw pump were carried out and the effect of screw angle and rotation speed on capacity of pump.
