Renewables-2017

A cost of primary energy of Solar and Wind in the order of magnitude can be cheapened by reducing their frontal dimension down to about 1.0 m2 unit, so such units are thinner proportionally and is negligible vs. a cost of electric generators being a lion's share per kilowatt, and cheaper than 0.5 UScent/kWh. [1]. (1) Al2O3 + 3 H2O = 2 Al(OH)3, heating and pressure 10 - 100 bars. 2 Al(OH)3 + k * (H2O = H2 + 0.5 O2) + Al2O3 + 3 H2O. All reagents are circular here, so they are practically free. Total energy consume is energy for the water thermolysis only, and at k = 1, being a heat of 242 kJ/mol H2 at T = > (150 + k * 242) / (450 + k * 54) = 500 C. vs. 2500 C conventional. If k = 0.5, T => 300 C. H2 product can be 242 kJ * 10^6 * 0.004 /3600 sec./2 = USD 133 /ton H2, (2) Catalyst: CO2 + H2 = HCOOH - formic acid. Joint target reaction: HCOOH + 0.4 * (H2O = H2 + 0.5 O2) + CO2 + H2. dH = 32 + 0.4 * 242 = 128 kJ. dS = 214 + 0.4 * (131 + 102 - 180) = 234. dG = 128 - 234 * T...

(1) CO + H2O (gas) = CO2 + H2, dH = - 41 kJ/mol. dS = - 86 J/mol *K, and T (41 + k*242) / (86 + k*54), and at k = 0.25, T>750C. So H2 (OPEX) = (41 + 0.25 * 242) * 1.1 / 0.5 - (41 * 10^6 /3600) * 0.15 * 0.03 = USD 170/ ton H2

July 01. 2026 Dear friends, spokepersons of DG Mobility and Transport. Ms. Anna-Kaisa Itkonen (Climate, Energy, Transport, Environment). Mr. Olof Gill (Economic Security). Mr. Ricardo Cardoso (Competition, Simplification). Here I appeal to your professional broadth of vision and contacts.

Airships instead of tankers and some other sea ships. David Judbarovski, 86, systems engineering, principle enventor, . judbarovski.blogspot.com, judbarovski@gmail.com, +972-54-6000514. Date: June 26, 2026. Abstract. Here is considered a big fleet of foldable airships with flexible thin walls and carrying a tank for cargo. Each tank equipped by engine and four tiny and cheap sensors of altitude and some propellants for soft landing, especially if crash cases, wartime etc.. Such airships are filled by light gas, e.g. hydrogen or ammonia or methane. For example, for import/export of 2.0 milliard ton cargo annually, it can be a fleet of 400,000 standartized airships used and manufactured distributelly. (USD 15,OOO, 36 km/h, 250 kW. 70 ton cargo, 10% of its weight is a fuel for 5,000 km range. Thay can be and must be manufactured automatized by total cost being negligible USD 6.0 milliards.)
