Breakthrough cheap and simple water splitting, if using micro-waves generator Author: David Judbarovski, systems engineering, retired, Israel judbarovski@gmail.com , Linkedin: David Judbarovski As an idea it goes me back to ~ 2014 Conventional vacuum micro-waves generators are characterized by very high energy efficiency of industrial quality electricity transforming into electromagnetic field at normal operational conditions (up to 80% for industrial quality samples) and can produce EM-energy up to many Megawatt in pulse of tens or hundreds kW average. It allows to use the EM energy concentrating on a small spot under  the water surface, on the small target to reach about 2500 Centigrade being enough to split the water on hydrogen and oxygen, the both are instantly cooled down to normal temperature by surrounded water, isn't needed to be distillate, and any water vessel can be a cheap plastic. Input electricity can be USD 0.001-0.002/kWh or even cheaper, and the electrici

Breakthrough ways to prolong a patrol or/and combat mission of helicopters Author: David Judbarovski, Israel, system engineer retired judbarovski@gmail.com , Linkedin: David Judbarovski The core idea goes back to ~1985 yr.   A helicopter can be paired with a mobile mother port (MMP) being a sea or land small high speed transport carrying a fuel and can be equipped by high voltage electric generator powering the helicopter in many practical cases by high voltage thin cable, and additionally it can carry some ammonia being a liquid at 20 bars pressure and a tiny heater can transform the ammonia in hydrogen by simple heating. That hydrogen can fill a flexible walls balloon can lift and fix the said cable to the helicopter at the sky, when it returns after its mission to repeat or prolong it. Additional analogous balloon, but much bigger one carried by MMP in its folded form, can be used to save a lot fuel at pauses in the helicopter combat mission.   The MMP can carry
