Renewables-2017

Practical system for cheap energy for all mankind needs   Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ First version and publication of that breakthrough technology goes back to July, 2017 and was titled as “Fresh look on wind power generation”. That was really a fresh & new look now improved and upgraded ([3870]- 26.08.2018) into a system, can produce by 0.2 US cent/kWh and deliver the electricity reliably and safely to any point of the world in practically unlimited quantity by final cost of 0.4 US cents for any consumption schedule. The key idea originally was to transform a route energy of a sail boat into rotation of a generator equipped by a special hydraulic turbine with effectiveness near 100%.. Now I offer to hang the sail in a form of thin mattress filled by hydrogen at height of 200-300 m with much more wind pressure A small pr...

Self-dragger as a new type of high-speed HPV Author: David Judbarovski, principle inventor, retired engineer, Israel judbarovski@gmail.com   Short CV: https://www.linkedin.com/in/david-judbarovski-1390944a/ Last articles: http://judbarovski.blogspot.be Archive since 2006 yr.: http://judbarovski.livejournal.com {158}/ [3859],18/08/2018 - [3861], 20/08/2018 A breakthrough concept of muscle powered transport is disclosed here below and named by me as “a Self-dragger”. Really, it is impossible to break physical laws, and I absolutely don’t intend to do it.   A pilot of my Self-dragger is looked from outside   like a man pulling something along by pushing a belt by upper part of his chest using a force of his feet and legs, but under his feet there are a pair of cycled belts instead of a road. The last said belts rotate a pair of electric generators, which electricity is stored by a rechargeable battery, and their total electricity is moving the sai...
