Novel power supply and consume Manifesto Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com , Israel Being very productive principle inventor and investigator on a firm basis of my work in wide spectra engineering and economics, I am sure that energy and production have to be and are ready to be green & cheap & abundant & inexhaustible, while all materials and parts and tools for that purpose can be recyclable.   I can declare that hydrogen economy and either hydrogen or hydrogen rich fuel like ammonia is a dead end paradigm that has been fooling humanity for decades.     I can declare that the best fuel is, was and will be a carbon based fuels produced from the water and the air by extraction a carbon dioxide of it, and the best way to consume such fuel as for stationary as for mobile applications, it is its high temperature reforming by the water vapor to produce clean hydrogen with carbon dioxi...

New look on cheap, effective fuel, incl. mobile applications Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com Abstract Shortly: Breakthrough novel sailed hydro-generators in oceans, transform wind energy in electricity of USD 0.0025/kWh used to produce on-board cheaply raw ethanol from water and air. The said raw ethanol  at USD 20.0/bbloe,  can be reformed by water vapor in hydrogen to produce electricity by fuel cells, stationary or on-board, .   To burn a steel cylinder with ethanol isn’t a simple task, and to explode it is impossible.  Now are known, intrusively promoted, and constantly exaggerated absolutely unviable hydrogen carriers. A small example: Can you imagine the ammonia leakage inside sea vessel? Where can you run from it?   Here is presented a fully theoretical solution of a problem of high contented hydrogen fuel, is safe against terrorist attacks and against its...

New kind of waterskiing/barefoot skiing. [4028]-27.07.2019 Author: Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com , Israel From idea to invention passed three days, and that delay was used for better understanding, why waterskiing now used in two variants only: (1) with a help of motto-boat towing or (2) cable waterskiing (see Wikipedia)   Water skiing/barefoot skiing is excellent and healthy as fitness and water sport. It activates all muscles, including legs' ones. And it doesn’t need special weather and geographic conditions. Moreover it can be used in severe weather conditions as an extreme sport. My offer is simple, small and light equipment of quite safe usage. In my case a rider doesn’t need a help of other persons and their boat, and even no skis as a variant. The rider can start with himself, and can safe himself if accidents. The rider needs the towing thing too, and it is a motorized and controlled lifesav...

Topic: Waste to Energy About typical mistakes of ideas to collect and even to sort the waste plastic Author: David Judbarovski, systems engineering, principle inventor, retired judbarovski@gmail.com , Israel I can’t deny a desirability to extract the waste plastic from nature and human living environment, even if being expensive in reasonable limits. Moreover, it can be profitable business in some practical cases. But to collect and even to sort any waste plastic at home before throwing, it is counterproductive and non-comfortable, and can be even not healthy, especially if food plastic. Much more reasonable the waste plastic to be thrown jointly with other unsorted home garbage to municipal garbage container for following garbage industrial treatment, e.g. for its gasification, and a most economical and clean way can be high temperature catalytic water steam reforming, and its high temperature heat as a by-product and its main product being   syngas (i.e. mix of...
