Step 5: Step 4. Add the Other Soup Cans. Put the last 2 soup cans under the two inductors. If your can has a coating, scrape a little off the bottom, on the inside with a knife. Make sure the cans are on a non conductive surface (not metal or water) and make sure they don''t get wet. Step 6: Step 5. Making the Wires.
2018425 · By Natasha Gilani. Electric power generation is typically a two-step process in which heat boils water; the energy from the steam turns a turbine, which in turn spins a generator, creating electricity. The motion of steam produces kinetic energy, the energy of moving objects. You also get this energy from falling water.
