Novel take-off & landing device Author: Judbarovski David, systems engineering, principle inventor judbarovski@gmail.com , Linkedin  The Article is not correct, because supercritical regions of gases at 1300 atm Abstract The take-off & landing device is four special water jets. The water is thrust out through a nozzle by gases at high pressure after ignition of “unitary liquid combustible” (ULC), i.e. stoichiometric composition of ammonium nitrate with urea, and liquefied by water as a solvent.   Take-off and then lending of aircraft of 10.0 ton full weight consume about 2.0 m3 of water for the water jet and 235 kg of ULC.   G = Q * t ; Q = F / v ; v^2 = 2 * g * 10 * P Here G (kg) – water consume for take-off or landing (1.0 m3) Q (kg/s) – water consume (200 kg/s) t (sec) – a time of take-off or landing (5.0 sec.) F (Newton) – the water jets total thrust (near 10 ton) v (m/s) – water outlet velocity through the nozzle (550 m/s) P (...

Breakthrough cheap water desalination Author: Judbarovski David, system engineering, principle inventor  judbarovski@gmail.com Note: Referring to my archive of several decades of work, being constantly upgraded and updated, I can declare that solar and wind energy can be USD 0.01//kWh, even several times cheaper (as heat as electricity), even if at engineering level of past ages. It can be pairs of small mirrors of about 1.0 m2 each and made of plastic foils and thin iron strings and sheets, and totally USD 15.0   The first mirror is planar and redirecting the solar beams onto the second mirror being a solar beams concentrator and can be motionless with motionless solar spot in its focus, so being reliable in operation. For southern regions it is about 3 m2 plant area per kW. Technology of the water desalination by series of evaporators/condensers (EC-s) is well known. Vapor of previous EC is evaporating the treated water by its heat of condensation. In...

CO2 production in huge amount at attractive cost from air Author: David Judbarovski, systems engineering, principle inventor judbarovski@gmail.com Introduction   Being twice/triple more energy effective, and much more convenient and save in usage vs. fuels, electricity can be practically only energy source for human live and global economics, if being cheap and inexhaustible and made from renewable primary energy and by recyclable cheap materials and tools for them. Carbon dioxide is one of the said materials, and can be produced from atmospheric air, then to produce carbon based chemicals to store such energy in compact and easy transportable form, and for other applications. It can save our planet against global warming. Here I will show a method of such CO2 production at attractive cost by cheap energy Note: Referring to my archive of some decades of work, being constantly upgraded and updated, I can declare that solar and wind energy can be cheaper ...
