Dear prof. Diana Golodniysky. See forwarded massage. Это для who is who. У меня к Вам будет необременительая просьба насчет зачем это я. Как до вас удобнее дозвониться, и по какому номеру телефона? ---------- Forwarded message --------- От: David Mj Date: вс, 26 апр. 2026 г., 11:19 Subject: New kind of catalysts for low temperature water thermolysis To: palkovits@itmc.rwth-aachen.de , David Mj , david judbarovski , Prof. Dr. Regina Palkovits. RWTH, Aachen CCE Center for Circular Economy. Dear friends. Apr. 26, 2026. (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. Because renewable energy of solar and wind can be cheapened in order of magnitude down to USD 0....

May 29, 2026. New kind of transport and transportation. Edited and slightly upgraded. New kind of transport and transportation. December 27, 2025 David Judbarovski, 86,retired, systems engineering, principle inventor, Israel. judbarovski.blogspot.com, judbarovski@gmail.com, +972-54-6000514 Abstract. Aircraft velocity, 720 km/hr. and 2600 kW only if standard container, but not aircraft. It moves on the ground inside vacuumed thin-wall tubes, but their vacuum is 0.2 bars, not more than in the sky above clouds at 7-10 km for ordinary airplanes. No traffic jams and no ice on fuselage. No wings, but ordinary air cushions of 200 kW. Computerisation is not sophisticated. There are no need to break anything, but to create such system from zero it would be cheap and quick (10,000 km would be about USD 100-millions.). 1.3 kWh/10 ton-km !!! Note. (1) Such system is many relatively short tubes eguipped by entrances and exists and connections each with others for "survivelance" and ...

Potassium chloride from sea water is unlimited resource. May 23, 2026. David Judbarovski, systems engineering, principle inventor judbarovski.blogspot.com, judbarovski@gmail.com. Freezing of the water consumes much less energy than evaporation. Solar and wind as a primery energy, the both can be about USD 0.004 / kWh or even less. [1]. Multy-stage freeze-thaw technology allows dewatering of 95% - 99% if constantly removing the ice from the water of natural seawater composition, and remaining is a targed product, potassium cloride 2.2 kg KCl/m3 seawater, inside the mix 16 kg with MgCl2 and MgSO4. Such KCl alone is eatimated by me as a cost of seawater freezing + 100 %. 1.0 m3 is by 6.1 kJ/mol = 330,000 /3600 sec./hr. = 92 kWh = 92 * 0.004 = USD 0.36 /m3 = 2.2 kg KCl = USD 170/ton KCl + 100% = USD 340/ton with a big reserve, vs. now fob price of USD 400 .

May 19, 2026 David Judbarovski, systems engineering, independent investigator, 86. judbarovski.blogspot.com. judbarovski@gmail.com, +972-54-6000514. Abstract. Temperature of the water thermolysis is reduced in the order of magnitude by different ways based on novel kind of catalysts invented. Thermal water splitting effectiveness is near 100% here. A cost of primary energy of Solar and Wind in the order of magnitude can be cheapened too 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 US cent/kWh. (1) Closed-loop H2O thermolysis. A catalyst is Ca(OH)2 = CaO + H2O. (a) Ca(OH)2 = CaO + H2O, dH = 109 kJ /mol, dS = 144 J/mol * K. (b) CaO + H2O + k * (H2O = H2 + 0.5 O2) + Ca(OH)2. T > (k * 242 - 109) / (k * 53 + 144). a mistake was here!!! At k = 0.8, T >= 180 C. Hydrogen is USD 160 / ton OPEX. judbarovski.blogspot.com/2...
