Sustainable Food Systems Nutritious & Lands saving panacea Team Leader David Judbarovski Solution Overview Solution Name: Nutritious & Lands saving panacea One-line solution summary: My solution is three steps way to introduce insects as Nutritious & Lands saving panacea in conservative meals cultures Pitch your solution. Insects being nutritive and rich by protein and fat like meat and fish, it have a very promising potential to solve a food problems of growing mankind population and its growing needs by the insects farming as it is practiced now in some counties and regions, and will save environment now destroyed more and by traditional agriculture. My solution is only way to introduce the insects as a panacea in meals cultures world widely, by use industry processing to reform the insects into traditional food forms, at first as additives, and then as a surrogate of traditional meals as it is practiced now by wide use of coloring agents, taste improve etc. It allows in...

Method to save a lot of world forests from extermination. It is repost from my letter to Greta Tumberg site some years ago. https://www.blogger.com/blog/posts/4646848601498022946: David Judbarovski, systems engineering, principle inventor, judbarovski@gmail.com Now the world markets consume annually about 600 million ton of papers and cellulose, but a half of it is recycled. For another 50% producing, it exterminates about 750 million ton of high quality trees and other plants on area ~ 3.0 million sq. km lands, because about 30 years needs for its restoring for such industry. Craft paper roll is ~ USD 200/ton, and cellulose is twice more expensive. Much more productive small aquatic plants and algae being reach of fibers, they are much more cheap and 100% alternative of present deforestation. A farming technology offered by me 9 years ago, it is a channel in a form of a double spiral for the water circulation. It can provide possibility to harvest triple more biomass of floa...

Realistic land transport and transportation with very high velocity. June 01, 2026 Absract. Supposed invention is vacuumed tubes and their nets allow cargo and/or passangers transportation with very high velocity upto about 700 km/hr, and economically increadible down to 0.1 kWh /ton-km, including train mode too. Background. "Today, while the vision of high-speed, continent-crossing vacuum trains remains largely theoretical, the underlying pneumatic technology from the 19th century is still actively used for transporting physical items (such as blood samples and documents) inside large hospital networks and secure facilities" (Google AI, May 31, 2026). Other concurrents are Maglev and Hyperloop, their material and parts are very sofisticated and so expensive ones, but being simply destroyable in wartime and in any other extremally times and cases. Claim 1. Trnsportation through vacuumed tubes is competitible and well scalable as a net of relatively short tubes, equipped ...

CV-2023, David Judbarovski, systems engineering, principle inventor, Israel cooperation and consulting 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. Short professional CV I was born in former USSR in 1939. 1962 –I was graduated as Dipl.-Eng. in Mechanics and Technology with emphasis on control and automation in chemical industry and mathematic simulation. 1962 –I was starting my professional career in systems engineering, at first with emphasis on applied mathematics methods. Through my life I had a duty experience in course in: (1) air traffic control, (2) microbiological industry, (3) pulp and paper industry, (4) technology of microelectronics, (5) capital construction, (6) typical design, (7) concrete i...

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 ...
