Breakthrough kind of electric vehicle - Upgraded

Breakthrough kind of electric vehicle – Upgraded Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com, Linkedin Abstract LiH + H2O = LiOH + H2 + 108 kJ at quite mild conditions, because at 370 C 108 kJ / (2.26 + 56 * 0.37) = 47 gram H2O = 2.6 moles H2 = H2/air FC = 268 kJ * 0.75 (efficiency) = 215 kJ 108 * 0.4 = 43 kJ, and totally 215 + 43 = 258 kJ = 258 / 7 / 3.6 = 10.2 kWh electricity / kg Li cheaply recyclable Materials are looped, so practically free ones. For comparison, 3.75 kWh/ kg gasoline, so 2.7 times less mileage. Reformed gasoline is 6.7 kWh, so 67% less mileage, and expensive, creates harmful exhaust, needs complex and long preliminary cleaning, and for recycling by competitive cost needs a lot of extremely cheap electricity, with its system efficiency is as small, as 25% LiH-fuel recycled industrially consumes 19 kWh/kg, so system efficiency is 10.2 kWh * 7/8 / 19 kWh = 47% . Indeed, LiH-fuel recycling by electr...

Very cheap. compact and effective offshore storage of huge energy

Very cheap, compact and effective offshore storage of huge energy Author: David Judbarovaki, systems engineering, principle inventor, judbarovski@gmail.com, Linkedin Abstract Invented type of huge energy storage is very cheap, compact and well scalable. It is pneumatic and inverted version of pumped hydropower storage (PHS), but isn’t needed in very specific terrains for deployment. Capital investment per kWh is practically free, while energy efficiency is 65% for charge and 80% for recharge. . Charge Surplus electricity is powering several air membrane compressors of total outlet up to 100 bars, and the pressed air is filling underwater reservoir covered. E.g. at depth of 1000 m. the cover is loaded on both its sides and compensated practically to zero. For example, 6.0 m3/c of the air at 100 bars is enough for each 1.0 GW electricity supply of 70% average capacity factor, while 100.0 hours reservoir can need less 0.5 km2 deep sea bottom of natural rigged surface area wi...
