Abstract.  
A cost of industrial production and the chemical ones too, depended on a cost of energy consume for them. During years time to time I search methods and devices to maximally cheapening of a Capex and OPEX of renewable energy generators, solar and wind ones based on fundamental engineering - The smaller such generators, the lower USD / kW and USD / kWh of them in comparison with gigantic ones being in order of magnitude more expensive.  [1], [2]. 

Small HAWTs are fixed to a rope being distributed on it. The said rope is fixed at down and stretched above by a balloon with a gas, is lighter than air.  Each HAWT is equipped by passive stabilizers.  The HAWTs are rotated in opposite directions each to neighboring ones to diminish the rope's loads. Being small, the said HAWTs is negligible in sum vs. whole cost of the system. In its turn the lion share of the cost is the cost of its electric generators being about USD 100 / kW. 
They are much preferable to be operated on seas and oceans vs. on-shore being very problematic in many aspects:  scaling, low winds, security and so on.  If open sea placement, electricity produced by a HAVT is converted in fuel components, e.g. in hydrogen, and/or carbon monoxide and so on. Such components are transported to floating terminals and converted on them in end products or in more transportable forms. 

The said HAWTs electricity is about USD 120 / ( 5 years payback * 8000 hours) = 0.3 US cents /kWh ~= 0.4 cents /kWh with reserve.

The system can be folded while lowering for treatment.

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 ...

Progressive Transportation Manifesto

Progressive Transportation Manifesto. Author: David Judbarovski, systems engineering, retired engineer, Israel judbarovski@gmail.com , Linkedin: David Judbarovski  http://judbarovski.livejournal.com ,  http://judbarovski.blogspot.co.il   It can be three levels global transportation system. (1) Urban traffic is provided by specially designed cars only and being electric pilotless cars fed from electric grid, with a tiny battery needed for emergency occasions only and offered as a new market products being a city taxi analogously to the UBER taxi optimized by time of delivery, number of passengers and cargo load. It’s ecologically friendly transport can save a lot of money and time for its users. It will avoid a human factor and traffic accidents.    (2) Personal cars must be avoided from cities’ roads and collected on the personal cars stations outside the cities and serving for suburb’s or rural routes up to about 700 km range. I can o...

Fresh look, Japan offshore

Central Research Institute of Electric Power Industry Japan, https://criepi.denken.or.jp/cgi-bin/en/inquiry/inquiry_entry.cgi   Dear Secretary, I can suppose you to be no big professional in engineering, so please forward my very interdisciplinary message to your institute professionals of Energy Innovation Center and/or to your Planning Group having intellectual Property Sectors, as its high importance merits for Japan energy security and economics and independence.   1.5.2019 Abstract During last three years the Japan government’s energy authorities declared and then rejected different Strategic Energy Plans (“SEP”), each more stupid than the previous ones, but the all of them need some trillions USA dollars of budget and being depended from foreigners. Being uniquely educated & experienced engineer (see short CV in attachment), I can confirm that Japan can be energy independent after three years of works by about one milliard USA dollars of total b...
