Abstract: This new invention of steam heating system is derived from my new steam baseboards. This new system combines the merits from hot water heating system and traditional steam heating system, but without the shortcoming. We can control the temperature of each room or every floor. This system is easy to apply for large apartment buildings. This system has several zone valves to control the steam flow. The zone valve will be controlled by thermostats. The returned condensation water will be pushed by John's effect. There is no need for the returned water pipes. The new steam baseboard is made of copper. The heat transfer is much faster than the traditional cast iron radiator. The room temperature is much faster to reach.

Abstract: This invention is to replace any mechanical wind wiper for a vehicle operation. We construct the air pump to blow the air to push the debris, rain water, and snow away from the windows. The pneumatic windshield clearing system includes an air source from engine assembly or and muffler coupled with vehicle, a metal pipes with small holes to have the high pressure pushed air from the top, bottom and side of windshield toward the surface of the windshield.

Abstract: It is a system to absorb the CO2 and release the oxygen (O2). We construct the mechanical and electrical instrument. We use solar panel to produce electrical power in DC. We add DC motors attached with rechargeable battery and solar panel. The motor will generate the current and bubbles to make air contact with sea water with dead zone in ocean (desert in ocean). We define the module which is independent platform will have the solar panel, rechargeable battery, 12 or 24 voltage, dc motor, anchor and current guide, bubbles generator. By this platform we can perform the photosynthesis to diminish CO2 and release the oxygen (O2). We can build many platforms to diminish CO2 and we are able to control global warming. We also establish the communication center to locate the position of the platforms.

Abstract: Condenser will create a lot of heat from compressor and exhaust heat has to be removed from it. This exhaust heat can be recovered to store in the hot water tank. More important the heat generated by freezer, air conditioner and refrigerator has to be removed either store in the hot water tank or dissipated by baseboard. We design this method to accomplish this goal. We use water to dissipate the heat and we do not waste the water. Water is very expensive about $5.00 per hundred cubic feet. This method will save fuel to pre-warm the water for hot water tank.

Abstract: Design the device Steam baseboard to use for steam heating. Water is not easy to get out and water creates the noise and does not easy to get out of the system. Water prevents the heating. We convert the hot water heating baseboard to steam baseboard by using the John's pipe and John's effect.
