Renewables-2017

July 01. 2026 Dear friends, spokepersons of DG Mobility and Transport. Ms. Anna-Kaisa Itkonen (Climate, Energy, Transport, Environment). Mr. Olof Gill (Economic Security). Mr. Ricardo Cardoso (Competition, Simplification). Here I appeal to your professional broadth of vision and contacts. Really, present Strait of Hormuz crisis reminded once again about bottlenecks of maritime transport and logistic, but it can be helped by blimps (foldable airships with flexible thin walls), as a panacea in all aspects of allegendly maritime competitiveness, transport temes (1) sustainable and cheap transport (2) mobility strategy, (3) militery mobility, (4) security and safety, (5) infrastructure and investmens, (6) research and innovations, (7) international relations More detailed see in "Airships instead of tankers and other sea ships", judbarovski.blogspot com/2026/06, posted on June 26.

Airships instead of tankers and some other sea ships. David Judbarovski, 86, systems engineering, principle enventor, . judbarovski.blogspot.com, judbarovski@gmail.com, +972-54-6000514. Date: June 26, 2026. Abstract. Here is considered a big fleet of foldable airships with flexible thin walls and carrying a tank for cargo. Each tank equipped by engine and four tiny and cheap sensors of altitude and some propellants for soft landing, especially if crash cases, wartime etc.. Such airships are filled by light gas, e.g. hydrogen or ammonia or methane. For example, for import/export of 2.0 milliard ton cargo annually, it can be a fleet of 400,000 standartized airships used and manufactured distributelly. (USD 15,OOO, 36 km/h, 250 kW. 70 ton cargo, 10% of its weight is a fuel for 5,000 km range. Thay can be and must be manufactured automatized by total cost being negligible USD 6.0 milliards.)

June 12, 2026 (1) N2 + 3 H2 = 2 NH3 is circular, so practically free. dH = -92 kJ /mol, dS = - 200 J/mol * K. T 580 C. A cost of the hydrogen of the water thermolysis is a cost of the heat for reaction (2) minus a cost of electricity as a by-product of exothermic reaction (1) and totally such hydrogen product is practically free too. Really, if heat is USD 0.004/kWh, [1], and heat in electricity is OPEX. References. [1] 2021 Annual Meeting. (397e) Cheap Energy is a Key to Competitive Artificial Fuels. www.aiche.org/conferences-events . A cost of primary energy of Solar and Wind in the order of magnitude can be cheapened by reducing their frontal dimension down to about 1.0 m2 unit, so such units are thinner proportionally and is negligible vs. a cost of electric generators being a lion's share per kilowatt, and cheaper than 0.5 UScent/kWh.

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 small physical items" (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 by exits and entrances along them. Claim 2. It is Claim 1, which transports are equ...
