Express diagnostics of CAVID-19 and its variations Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com , Linkedin CAVID-19 and its variations and their any stage as many other pulmonary diseases can be diagnosed/detected even if in quite earlier stage as quick as some seconds per capita and as cheap as some cents by a voice analysis both by hardware and by ear after short training. It is well known technique of patterns recognition, and can be developed at practically negligible investment and by tiny group of engineers or even by one engineer and worldwide scaled in a quite short time. And the only obstacle can be probably lack of political request to get rid our mankind of this pandemic, if the last being globally planed as a sort of the fourth world war to get rid   our world of “populations garbage”, and simultaneously to save infrastructure for healthy part of mankind.      

Siemens energy storage in rocks vs. the mine- Upgraded   Author: David Judbarovski, system engineering, principle inventor judbarovski@gmail.com , Linkedin The Siemens scheme is realized by rocks heating of 30 MWh in 2000 m3 of rocks. Their scheme disadvantage is a variability of the temperature after the storage, when input energy varying and its output are unstable. So a block with turbine-generators works unstably, and it decreases their energy efficiency and reliability.   It is two blocks scheme and with underground counter-flow heat exchanger at the rocks being cheap and abundant natural stuffs. The first block is charging circuit for transforming the wind farm electricity in the heat of high temperature, and the second block is steam circuit and its output electricity goes to grid. The rocks can be heated and store solar energy too, as electricity as thermal onee. In the last case I can recommend two mirrors as solar thermal units of about 1.0 m2 of sol...

Sustainable Food Systems Nutritious & Lands saving panacea Team Leader David Judbarovski Bookmark to Your Dashboard Report this solution /I was invited by MIT SOLVE Challenges on 25.02.2020, and submit my solution on 2.03.2020 16:40/ 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 countries and regions, and will save environment now destroyed more and more 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 tradi...
