Abstract: The invention includes: 1. One or more stainless boiling chambers 2. Mechanisms for low cost heat production, 3. Mechanisms channeling air molecules flow into the non potable water chambers or mechanisms absorbing air from the drinking water chambers and other chambers and mechanisms of the system, through folded long and spacious tube in a grid shape or in the form of cyclic coil, thus reducing water vapor pressure [BERNOULLI], lowering boiling temperature and increasing evaporation rate, 4. An intermediate chamber to separate water vapor from the droplets of non-drinking water, 5. A tank to feed boiling chambers 6. A single or dual function thermostat or a system of two thermostats, 7. Ion trapping mechanism, 8. Mechanisms for cooling, refrigeration, compression, ice packs and fans to condense water vapor, 9.

Abstract: The present invention relates to a device which indicates the safety limits of the air pressure in each one of the pneumatic tires of a vehicle by transmitting appropriate information from the wheels to the driving control board. Transmission of information is based on the capacitive coupling between rotating and non-rotating conductive annular surfaces (2-5, 12-19, 72-75) which are mounted into channels of insulated bases (6-9) fixed in the available space between the bearing flange, the braking system and the wheel bearings (66) and are forming cylindrical and plane capacitors. An electronic circuit incorporates these capacitors as basic elements for its operation, and also an AC bridge (20) to give an automatic compensation by measuring the differential capacitance for each pair of the wheels to avoid faulty indication due to causes like humidity, temperature, etc. Also a simple electronic circuit can be used for each one of the wheels.
