A real way to stop the global warming

Abstract

It is one of my other offers allowing the global warming to stop. Here it is special vertical wind turbines being very cheap and simple in manufacturing and installation, and their electricity being cheaper than one USA cent per kWh at sites with wind velocity equal or more than global average one being 3 28 m/s at land.
For example, the present electricity consume of USA can be satisfied by 0.7 cent/kWh ($ 300.0/kW for all), distributed in total on 0.7% of its territory not excluded for other usage .

Disclosure for experts

Our vertical wind turbine is a vertical chain of special units. Each unit comprises three plane blades of identical window leaf of thin steel sheet. The wind flow rotates the said units by closing alternately the window leafs or opening them, and it rotates a low speed gearless permanent magnet synchronous electric generator.
The neighboring units are rotated oppositely, so we can minimize torsion loads. The said turbine is hung in the air by a balloon with a gas, is lighter than air, i.e. by natural gas or hydrogen.    
The lowest end of the said chain is fixed by a rope through bearing connection to the land or by heavy load to the land.
The said turbine can be 200 m height (from 100.0 m to 300. 0 m above sea level) and 4.0 meter of blades width, can produce about 100 kW = 880,000 kWh. or much more

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.
