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.)

June 12, 2026 (1) N2 + 3 H2 = 2 NH3 is circular, so practically free. dH = -92 kJ /mol, dS = - 200 J/mol * K. T 580 C. A cost of the hydrogen of the water thermolysis is a cost of the heat for reaction (2) minus a cost of electricity as a by-product of exothermic reaction (1) and totally such hydrogen product is practically free too. Really, if heat is USD 0.004/kWh, [1], and heat in electricity is 0.25 effective, and USD 0.03 /kWh sold, so USD (210 - 200) = 10 / (2 * 0.4) = USD 12.5 /ton H2 product is negligible OPEX.

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.

Environmentally harmful impact can be corrected June 05, 2026 David Judbarovski, 86, systems engineering, principle inventor, Israel, [1] CV-2023, judbarovski.blogspot.com, judbarovski@gmail.com, +972-54-6000514. Environmentally harmful impact of the human activity has to be and can be corrected, see (1) widespread deforestation, can be corrected, see [2]. (2) fossil fuels for energy and extensive agriculture must be and can be corrected too, see: Drastically land saving technologies to provide all mankind needs by energy and foods.
