Electricity has been generated first time ever on the face of the planet by filling a tank with 200 liters of water roughly 15 m above the floor so as to generate a natural vacuum for the so-called BIG BANG for Big Industry Grade Boiling Accelerated Naturalistic Generator. A turbine and a generator were installed in the supercooled Torricelli vacuum chamber created on top of about 10.3 m high water column. With a 20 mm polyethylene pipe, a 6 mm glass pipe nozzle and a pressure gauge ready to go, a vacuum space was produced by use of a bypass line to discharge air into the suction pipe to kick off the proof-of-principle test for the BIG BANG setup. The boiling accelerated two-phase mixture of gas and liquid phases formed in the nozzle region is considerably cooled down in the vacuum and passed down to drive the turbine whereby generating electricity. When boiling is accelerated by difference between the atmospheric and ultra low, or almost vacuum, pressures, the working fluid’s thermophysical properties vary sizably from the liquid phase to two-phase mixture of liquid and vapor/gas phases. Specifically, its temperature plummets, specific volume soars, and thus its flow velocity picks up dramatically. This first-of-a-kind engineering endeavors to seek big industry grade fluid machinery to convert this fluid’s kinetic energy into mechanical energy of the turbine rotor all the way to electrical energy resorting to ecological, naturalistic, renewable, reusable, recyclable resources for the benefit of mankind.
