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 front flow, rotates the wheel and the generator with highest energy efficiency, while two other window leafs rotates free of resistance being opened by the front water flow.   

The said boats go there and back. They harvest the wind energy and transform it into electricity. 

 Certainly, we can ask me about a way to store and to transport such electricity from the thing floatng in the open ocean? I suppose the electricity to be transformed on-board into chemical energy of a liquid, and the best it can be ammonia. The gaseous ammonia is liquefied at quite low pressure. The ammonia is excellent for energy storage and for energy transportation, and then for distributed power generation.

The ammonia can be produced by nitrogen-hydrogen fuel cell or by classical Haber-Bosch process or by metal hydride and nitride chemical cycles;  

At first, on-board the said electricity is feeding some small magnetrons and their microwaves are concentrated on a tiny focus inside a small vessel with the water and thermally splitting such tiny area of the water giving the hydrogen, is used on-board for ammonia production from the said hydrogen and nitrogen. The last is delivered periodically for the said boat in storage quantity in compact pressed form from a floating factory serving to extract the nitrogen from the atmospheric air. The small part of the said ammonia gives energy for the factory, while a lion share of the ammonia in its liquefied form is the end product of the business.

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 creates additional

Equipment for Short Take-off and Landing (E-STOL)

Equipment for Short Take-off and Landing (E-STOL) Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com , Linkedin Abstract My E-STOL comprises a aerodynamic resistance of quite small area (SAR), being rigid and turnable, and a water jet device (WJD), comprising high pressure water jets in corners of quadrangular frame. The SAR can be very quickly erected or downed to turn it into additional wing-kite for short gliding in the sky. The WJD provides stabilization below stall speed and serves as start support, while landing or take-off. It is very attractive for Navy aviation, because allows high cruise speed, extremely short runway, and better reliability vs. helicopter, and we can repeat approach, if taking a portion of ambient sea water, in flight by simple pails.     The water is thrust out through the jets by gases at high pressure after ignition of “liquid vigorous combustible” (LVC), e.g. stoichiometric composition of amm

Breakthrough new fuel is better than oil

Breakthrough new fuel is better than oil David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract Lithium hydride being reformed by water vapor in hydrogen then by fuel cell can create 5.25 kWh electricity/ kg. LiH, vs. 3.75 kWh per kg gasoline, while that LiH needs for its recycling 10.3 kWh renewable electricity , so system energy efficiency is 50% without any harmful exhaust. For the oil, analogous technology or by burning the both are followed by the oil recycling, they are 25% energy efficient with a lot of harmful exhaust.. Really For Lithium hydride, it was evaluated by me in the article : “Breakthrough kind of electric vehicle” in https://judbarovski.blogspot.com /2022/11 , posted at Nov. 05, 2022 For the oil, it is recycled from atmospheric CO2 and hydrogen produced by the water splitting.
