Дурак-немец правда наполняет свой парус гелием, но можно ведь и природным газом, тоже ведь вдвое легче воздуха, зато дёшего и всем доступно, и не опаснее, чем пользование газовой плитой, и подстраховать это не дорого. у немца управление компьютеризированное и на этом он забуксовал пока, а спортсмен и без сложного софта легко управится... А насчёт наво...

Mutual beneficial energy deal to save EU and Ukraine David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract It can help Ukraine and Europa to survive coming winter at fuels shortage now and forever. . Recently invented wind power generator (SVAWT), being simple, cheap, compact and reliable, it can be made of common and mass traded materials and parts, allows breakthrough cheap and distributed energy consuming totally minimal area, when Russia invasion and present extermination of infrastructures in Ukraine. Background The said SVAWT (special vertical axis wind turbine) was disclosed and evaluated as for politics and economist popularly, and as for professionals. Surplus power creates competitive fuels. (see “Promotion, new wind power, October 2022” , posted on October 12, 2022, in https://judbarovski.blogspot.com/2022/10 ). SVAWT is slightly heated at danger of freezing... As for Ukraine, it can be recommended in the said war time, to...

The slogan It’s possible to reach energy independency sooner and forever based on new look on wind power generation and common materials and parts mass produced and traded domestically, and maximally saving the nature and conventional fuels infrastructure and economics. What have to do for it? – Only to do it! As soon as possible. Synthetized fuels cheaper USD 70.0/bbloe, and how to reach it David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Promotion, popularly for politics and economists, followed by Disclosure for experts at the bottom To close 150 milliards m3 deficit of natural gas, it is enough about 50 milliard dollar budget. More than one year ago, Ministry of Energy (DoE) USA publicly admitting that more than 100 GW offshore Wind power capacity built in USA, is not an achievement, but disaster, and were forced to seek help outside their system for ideas (Request for Information (RFI) DE-FOA-0002389 asked by the DoE Office of Energy Eff...

Synthetized fuels cheaper USD 70.0/bbloe, and how to reach it David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Abstract New kind of wind power generation being a multi-sectioned rope fixed below and stretched upward by a balloon lighter than air, while each section comprise a frame with pair of tall and thin VAWT-s symmetrically to the rope and rotated each in opposite direction to the another one to neglect torsion loads to the rope. Totally its electricity is much cheaper USD 0.01/ kWh - limit allows cost competitive fuels from CO2 of the air and H2O split. It can be deployed as at the land as abundant and cheaper in seas and oceans, even if local deepness down to 3 km or deeper. At the last case, the rope is fixed to a small container filled by air underwater near water surface, while the container is fixed to deep water bed by ropes at its three different points Really: (1) The lion share of such electricity cost is a specific price of e...

Thin tall wind turbine with paired horizontal units David Judbarovski, systems engineering, principle inventor judbarovdski@gmail.com It is a new kind of wind turbine. It is stretched by aerostat to a height up to some hundreds meters with more wind velocity. Its paired units on both sided to the tall axle are rotated in opposite directions, so diminish drastically its torsion loads and the axle is very thin and light rope can be fixed to a sea deep bed . All construction and its units in particular, have big power-to-weight ratio, and a lion share of a total cost is a cost of electric generators. The specific price of their generators is about USD 100.0/ kW, so a cost of electricity would be no more than $150 / (9000 kWh/yr.* 5 years payback) = 0.35 cent/kWh
