Fully protected payment cards supported by national database for transactions Author: David Judbarovski, systems engineering, retired engineer, Israel judbarovski@gmail.com , Linkedin: David Judbarovski The world without the money is possible in nearest future, while all transactions can be transparent and fully protected against all sorts of criminals. If being supported by national database for all transactions (NDBT), any criminals can be simply and quickly and cheaply detected automatically.   It needs the following steps. (1) The Payment Cards are personalized, even if for businesses.           (2) The Payment Cards are protected by personal identification by face, voice, finger print, signature, passwords of any sorts, and alarm. Such protection is using AI (artificial intellect) application. analogously present practice. (3) Before first transactions, there are used a learning of the said AI and its testing. (4) Nobody is able to pay from your Payment Card,

Smart bomb protected from countermeasures Author: David Judbarovski, retired, judbarovski@gmail.com The smart bomb is offered to be protected and controlled by two different means: (1) a microchip delaying input signals can allow to detect electromagnetic attack of defense and to protect and to delay automatic setting as the start coordinates as the end ones for the smart bomb’s microcomputer;             (2) well known precise inertial control by accelerometer can provide precise hit and additionally allows maneuvering in the air;

Novel electric vehicles fueled by gasoline and saving 50% of it Author: David Judbarovski, principle inventor, systems engineering   judbarovski@gmail.com , Linkedin The main obstacle for mass introducing of hydrogen as a clean and very powerful fuel and fuel cells consuming the hydrogen as high efficient electricity source, there are flammability and highest explosion hazard of the hydrogen, and practically 100% lack of hydrogen refueling stations in comparison with gasoline ones being everywhere, while the gasoline much less dangerous in usage and very suitable. In another hand, hydrogen fuel feeding direct hydrogen fuel cells allows potentially very high energy efficiency near 100% and practically now being about 65% and very low cost of about USD 40.0/kW as constantly declared about them by DOE (Ministry of Energy) of USA, but underlining that them can be reachable if being mass produced not less than 100,000 -500,000 units annually.     Being summarized all the sa
