Novel class of Warming window glass (WWG)

Novel class of Warming window glass (WWG) Author: David Judbarovski, systems engineering. principle inventor Material of the window glass invented and its outer surface are ordinary ones, but its inner surface has roughness of 10 micrometer or so. Such window is transparent for seeing both from inside and from outside, but reflecting the infrared radiation from inside the room. Such window glass can be made while hot rolling, so it is as cheap one as ordinary window glass

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.

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...
