Abstract.
CO2 + 3 H2 = 2 H2O + CH2 (abbreviation of Hydrocarbon fuel)
Disclosure.
1) KOH + CaO + H2O reagents continuously enter in a reactor & mixer. The natural air) continuously bubbles through the reagents and reacts at first quickly with KOH as a catalyst, and then with CaO, producing growing layer of CaCO3 sediment.
(2) CaCO3 + 2NH3 = N2 + 3 H2 + CaO (recycled) + CO2 (target product). Here 2NH3 = N2 +3 H2 is reversible reaction, serves as a catalyst, reducing temperature of CaCO3 decomposition from 850 C down to 375 C.
Because all reagents used here are circular and practically free, the target product of CO2 is breakthrough cheap too.
Ship powered by sun PV-cells
Ship powered by sun PV-cells Author: David Judbarovski, systems engineering, Israel, retired engineer judbarovski@gmail.com , Linkedin: David Judbarovski A real ship of 165,000 ton tonnage with optimal power of 37.000 kW would need about 37,000 * (8000 /1600) / 0.2 ~= 1.0 million m2 PV-cells = 1000 m * 1000 m, can be towed by light foldable sectioned construction being unfolded in open sea and folded before entrance to a port. Now, such towed solar power plant is no more than 100.0 million USD, while the said ship total cost is 185 million USD. Certainly, we have to consider a costly power storage and three days = 72 hours storage can be quite enough, while I can recommend to use Li-H fuel cells can be as a power source for the ship. A total weight of the said fuel cells is negligible vs. the ship tonnage, while the fuel (Li and H2) of such Li-H fuel cells can be thermally recycled without any interrupting of its work by Joule heat of the said PV-cells’ electricity. ...
