Super high speed vehicle of big payload 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 Here it is disclosed and evaluated quite detailed an incredible vehicle, had been published as a principle invention idea and was archived in Russian in my blog more than 10 years ago (2007-02-18 10:37:27), but isn’t noticed in the world. It can be an Ultra heavy military transport, is better than Pelican Boeing Ultra (ground effect vehicle). Such conception can be helpful for many civil applications too as a super high speed transport of big payload. A key element of my invention is to add the water steam cocoon to the hull of conventional design of ship. Such method allows the friction losses of energy to be practically zero, so the hydrodynamic losses...

Natural gas import can be 5-10% cheaper The imported LNG’s cost is higher by about USD 80.0 per 1000 m3 NG, than sold by importer. The NG transportation by pipes and by ships for long distance is even more expensive vs. LNG transportation. A shipping (with operations in it) is ordinary USD 25.0 +/-   depends on a distance, and regasification can add another USD 13.0 and need special terminal on a sea shore and special tankers. If using instead transportation by sea, the transportation by air by blimps (nonrigid airships) can drastically reduce a cost of LNG transportation, if the said blimps are filled by NG (47%) in gaseous form under a tiny pressure and bearing the LNG as a cargo (53%), while about 1.5% of it is used as a fuel for the said transportation for 6,000 km. For European Union it can save now totally more than Euro 1.0 milliard annually for transportation expenditures alone, because NG import by European Union being now about 280 milliard m3 per a yea...

Super high speed ships that changes a game in transportation  For the present, it is without any consideration of upper water sructure of the ship, i.e its aerodynemic drag force It is later upgraded by other posts Authaor: 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 Here it is disclosed and evaluated quite detailed an incredible sea transport, had been published as a principle invention idea and was archived in Russian in my blog more than 10 years ago (2007-02-18 10:37:27), but isn’t noticed in the world.

Sea water desalination cheaply 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 {156}-(1)-2.04.2018 I show my technology and its introduction for Israel as an example. It is USD 0.1/ton of fresh water, and could need 12 million USD as a CAPEX for 1.0 milliard ton annually. It is some greenhouses comprise three layer of PET films as a roof with an air gaps between them and a layer of sea water as an input on the bottom, for solar evaporation up to saturated vapor at the greenhouse temperature. Another input of the greenhouse is an output of a heat exchanger has the said saturated vapor as its input for condensation by ambient air being its another input. The said condensate is conditioned in fresh water product by a little share of the wa...
