Water thermolysis at breakthrough lower temperature with a help of CatERR. January 12, 2026 Note: CatERR is a new kind of catalysts are an exothermic reversible reaction being combined with another reaction in joint chemical process, to make it happen at designed conditions and to restore the said reversible reaction's reactants. David Judbarovski, systems engineering, principle inventor, retired, judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. Here CatERR can be 0.5 N2 + 1.5 H2 = NH3, dH = - 46 kJ, dS = - 103 J / mol * K, and the water thermolysis is (NH3) + 0.25 (H2O = H2 + 0.5 O2) + (0.5 N2 + 1.5 H2), dH = 46 + 0.25 * 242 = 106, dS = 103 + 0.25 * (131 +102 - 180) = 116, and dG = 106,000 - 116 * T 640 C. Moreover, because all reagents here are circular and practically free, a cost of the hydrogen is equal the cost of energy consumed, while the heat of the CatERR can be converted effectively in electricity and sold, the H2 is 106 kJ * 1.1 - 46 * 2.5 = negligible + Cap...

January 05, 2026 Novel possibility to power EV-s indirectly from remote solar and wind plants. [1], [2]. David Judbarovski, systems engineering, principle inventor, judbarovski@gmail.com judbarovski.blogspot.com Abstract. It is possible for solar PV-panel to be equipped above the roof of electric vehicles, partly to compensate electricity consumption by their batteries. For example, if sun light is 1500 kWh/m2 annualy on the said PV-panel with its energy efficiency 20% and area being 1.5 m2, it can add maximally 450 kWh to the said battery annualy. so negligible for the batteries daily, but very sufficient economy for regional and global electric grids. Really, for the Los Angeles city only, [3], [4], the system offered here can save 450 kWh * 7.0 million cars registered now * 25% EV in total cars in 2035 yr., so about 1.0 milliards kWh, so to substitute about 0.5 Gigawatt power of new built thermal and nuclear power plants (TPP or NPP ) by clean and cheap renewable energy. Referen...

David Judbarovsk, 86,retired, systems engineering, principle inventor. judbarovski.blogspot.com, judbarovski@gmail.com Abstract. It is trasport and transportation for conventional vehicles and conventional cargo. Aircraft velocity, but not aircraft. It moves on the ground inside vacuumuized tubes, but their vacuum not more than in the sky above clouds at 7-10 km hight now used for ordinary airplanes. No traffic jams and no aicing on fuselage. No wings, but air cushion. 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 1,5 milliards). The tubes can be thin-wall reinforced domes.

New kind of catalysts are an exothermic reversible reaction being combined with another reaction in joint chemical process, to make it happen at designed conditions and to restore the said reversible reaction's reactants. David Judbarovski, systems engineering, principle inventor, retired, judbarovski.blogspot.com, judbarovski@gmail.com. Abstract. (1) CO + H20 = CO2H2 - formic acid, it is the said catalyst, beinmg the said exothermic reversible reaction. (2) (CO2H2) + 0.5 H20 = 0.5 H2 + 0.25 O2 + (CO + H2O). It is the said joint chemical process to split the water at quite mild conditions and served to produce cheap hydrogen. Really. Energy for those can be renewable and as cheap as less USD 0.01 /kWh down to 0.4 cents or less. [1], [2], [3], [4], [5] and so on. Reaction (1) is classical. dH = - 73 kJ, while dS = - 247 J/mol * K. Reaction (2) goes at dH = 73 + 0.5 * 242 = 194 kJ. dS = 247 + 0.5 * (131 + 102 - 180) = 274. dG = 194 - 274 * T 435 C. Because all reagents here are circ...

New kind of catalyst. December 22, 2025 New kind of catalyst is an exothermic reversible reaction being combined with another reaction in joint chemical process, to make it happen at designed conditions and to restore the said reversible reaction's reactants For example, it can be thermochemical water splitting in hydrogen and oxigen. (a) CO + H2O = CO2 + H2 - 41 kJ. It is exothermic reversible reaction being classicsl one. dH = - 41 kJ, dS = - 34 J/mol*K. T 2000 C, while conventional thermal water spliting needs much hither temperature. Here CO2 and CO are circular and practically free, so a cost of H2 is a cost of energy consumed. Heat can be renewable energy and 0.4 US cents/kWh [1], and heat in electricity can be 30% energy efficiency and 3.0 US cents /kWh tariff for sale. So the hydrogen cost is here by (0.33 * 242 kJ + 41) * 1000 * 0.004 / 3.6 - 41 * 1000 * 0.3 * 0.03 / 3.6 = USD 30 for 0.66 ton H2 product, so 30 / 0.66 - USD 45 /ton H2, Opex, vs. the water electrolysis 286 ...
