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.

Cavitation phenomenon has long been a difficult problem that regarded as negative event to fluid machines or industrial facilities. In the latest, however, some engineers became to understand the power of cavitation and use it to cleaning wall after developing cavitation nozzle. In this paper, we introduce new concept for power-generation system using cavitation jet flow maid by nozzle and impulse turbine in vacuum condition. The vacuum needed to make cavitation is generated naturally by Torricelli's vacuum, 10.23m effective head drop without additional power. We analyzed water's boiling and the steam's mean free path according to vacuum purity levels for nozzles and turbine blades. The nozzles make water accelerate in the neck and boil in expansion section of the nozzles. The shape of the impulse turbine is designed for absorption of the molecule's kinetic energy of the steam.
