What is better for fossil fuel economics?   Author: David Judbarovski, systems engineer, principle inventor judbarovski@gmail.com This could halve decrease the global market of oil and gas for transport, and collapse exporters’ economics…but save global environment and money and health of consumers.   Nevertheless, no one of NG/oil exporters agree to clean it for such purpose and to dig his own grave, but it can be made by importers, even if they would need   at first to gasify LNG and then after purification to liquefy it again for further transportation for consumers. Such transformation is not so expensive, consuming relatively negligible parts of the LNG.     I wrote (see “Vehicles’ fueling by reformed hydrocarbons”, posted 20.12.2020 in https://judbarovski.blogspot.com/2020/12 ): “The purified NG/liquid hydrocarbons is reformed by the water steam in excess quantity and at high temperature creating a gaseous mix of hydrogen and carbon dioxide ...

  Power boosting of commercial PV-panels, re edited Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com            Abstract The commercial PV panel is exposed to the sun and a thin film reflector adds more sun to it For sunny regions of subtropics, it is totally 160 % solar power of the said PV-panel and can be cheaply controlled vs. conventional two axis tracking, needs more heavy and costly mechanics. The reflector is attached to one side of the said PV panel  If the sun is at A-angle to horizon and tracking reflector being at B-angle to horizon, and B = 45 + A/2 > A, the solar flux is reflected perpendicularly on such panel   For 1.0 m2 panel, optimized W(kWh) ~= (Direct Normal Irradiation = 2400 kWh/yr.) * (0.85 * Sr * (Sin (B – A) = Cos B) + Sin A + 0.15). here Sr = 2 m2 is the reflector area. For example, for Israel and South Australia, a 1.0 m2 panel of 1...

Vehicles’ fueling by reformed hydrocarbons Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com   Abstract Full cycle of a vehicle fueling by purified hydrocarbons reformed by water steam would consume twice less fuel than by Internal Combustion Engine (ICE)   It is: (1) The oil/NG purification after its extraction from the production wells and before transportation to consumers. For that purpose, the oil/NG contaminants are avoided either by the aerated seawater or by its analog in a form of mineralized fresh water aerated too. (2) The purified oil is refined by a refinery. (3) The purified NG/liquid hydrocarbons is reformed by the water steam in excess quanyity and at high temperature creating a gaseous mix of hydrogen and carbon dioxide in moles ratio of 4 : 1, directly on-board of a vehicle. The said steam reforming is endothermic and consumes about 210 Joules/mol. (4) The said carbon dioxide is poiso...
