Green and cheap water and electricity from the air and centrifuges

Israel. 2.4×10^9 m3 H2O annually = 80 m3/sec. = 80×10^6 gram/ (11 g/m3 air humidity) = 7.2×10^6 m3 air/sec. Centrifugal air separation in (3 steps x 6 min = 0.3 hours in a step = 25,000 in a year . So 7.2 × 10^6 m3 air ×3.600 sec/25,000 = 10^6 cenrifuges, or 7.2 m3 air for one step of separation. 2.4×10^9 m3 H20 × 10^6 g × (40.66 kJ/mol)/(18 g/mol)/3.600 sec. = 1.5 ×10^12 kWh × 0.3 = 500×10^9 kWh electricity as a by-product.

Ship powered by sun PV-cells

Ship powered by sun PV-cells Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski A real ship of 165,000 ton tonnage with optimal power of 37.000 kW would need about 37,000 * (8000 /1600) / 0.2 ~= 1.0 million m2 PV-cells = 1000 m * 1000 m, can be towed by light foldable sectioned construction being unfolded in open sea and folded before entrance to a port. Now, such towed solar power plant is no more than 100.0 million USD, while the said ship total cost is 185 million USD. Certainly, we have to consider a costly power storage and three days = 72 hours storage can be quite enough, while I can recommend to use Li-H fuel cells can be as a power source for the ship. A total weight of the said fuel cells is negligible vs. the ship tonnage, while the fuel (Li and H2) of such Li-H fuel cells can be thermally recycled without any interrupting of its work by Joule heat of the said PV-cells’ electricity. ...

Progressive city-car realization and powering-Updated,#1

Progressive city-car realization and powering-Updated, #1 Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Archive since 2017 yr: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com [3791]-3/11/2017,   My three levels’ conception of progressive transportation was disclosed in http://www.judbarovski.blogspot.co.il/2017/05/progressive-transportation-manifesto.html  (Progressive transportation manifesto, May 02. 2017). Its first level is a city-car.   Special designed city-car is a car moved electrically and equipped by very small battery as a city-grid element, and it isn’t big news now. Such cars are to be much cheaper and simpler than conventional cars and save a lot of energy. But I can suppose strictly to reject all sorts of powering them from underground, because it is energy ineffective and ...

Fresh look on wind power generation

Fresh look on wind power generation Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski [3749]-25/06/2017, {149}-( 1 4)- 0 8. 07 .2017 Abstract   It is a new kind of a wind power generator. Its energy effectiveness can be close to 100%, while it has very simple design, and its electricity is about 0.3 USA cents per kWh, because a lion share of the said cost is a share of a geared electric generator. It works in open sea in principle, while global wind kinetic power is about 20.0 milliard kW. The power generation unit is a small pilotless boat with a flat sail. Four small floats placed symmetrically at a distance from the boat, are serving to compensate a torque force of the wind on the sail. A relatively small water wheel with three blades in a form of window leaf each (WWWL) is fixed underwater to the boat moved by the sail. At any moment only one window leaf is closed by the fron...
