Abstract: The present system produces electrical power from burning coal or natural gas, with almost zero air pollution. In its lack of air pollution is similar to air and wind power, but less costly. Its power may be produced day and night and when the wind is not blowing. Its power is less costly than nuclear power, and without the possibility of radiation damage, melt down, and log-term radiation storage. The US tax law provides a $10 or $20 credit per ton CO2 for sequestration in “Secure geological storage”. See 26 USC §45Q. The estimated cost of this system's CO2 carbon capture is below that tax credit. The tax credit of $20/ton (large coal power station—800K tons of CO2) would generate a profit of millions of dollars. This system's capture cost for CO2 is about the same in gas or coal plants. However, coal plants generate about 3 times the CO2 tonnage of gas plants per unit of electric power. In one example, the system uses combined cycle gas turbine-steam units (CCGT) thermal efficiency of 50-60%.

Abstract: The present invention discloses a system for the separation and non-polluting disposal of carbon dioxide derived from the exhaust of burning fossil fuel, including a gas separation system which includes: a first stage of gas membranes C02 separators, means to transport exhaust gas to the first stage, the first stage separating C02 from other gases in the exhaust gas, a second stage of gas membrane C02 separators, means to transport permeant gas that passes through the membranes of the first stage to the second stage, the second stage producing C02 permeate gas of purity greater than 90%.

Abstract: A hybrid lead acid electric storage battery uses conventional lead-acid secondary battery chemistry. The battery is a sealed battery or an unsealed battery. The battery has a set of positive battery grids (plates) having cores of thin titanium expanded metal with a thickness, if flattened, preferably in the range 0.2 mm to 0.7 mm and most preferably 0.3 mm to 0.4 mm. The grid cores are of a titanium alloy containing a platinum group metal. The cores are coated with hot dip lead and are not lead electroplated. The negative plates are carbon based assemblies. Each such assembly has a metal core, preferably a sheet of expanded copper, a corrosion shield sealing the metal core, and an outer layer primarily of activated carbon covering the shield.

Abstract: A lead acid electric storage battery uses conventional lead-acid secondary battery chemistry. The battery may be a sealed battery, an unsealed battery or a conventional multi-cell battery. The battery has a set of positive battery grids (plates) which are constructed with a body portion of thin titanium expanded metal having a thickness preferably in the range 0.1 mm to 0.9 mm and most preferably 0.2 mm to 0.4 mm. Typically the battery would have over 250 grids in a 12 inch long battery case.

Abstract: In a lead acid electric storage battery using conventional lead-acid secondary battery chemistry, the battery may be a sealed battery, an unsealed battery, a conventional multi-cell battery, or a bi-polar battery. The battery has a set of composite negative battery grids (plates) which are constructed with a thin aluminum core having a thickness preferably in the range 0.05 mm to 1.3 mm and most preferably 0.2 mm to 0.6 mm. A layer of aluminum oxide removal metal, preferably zinc or tin, covers the aluminum core. Optionally, a protective film of tin dioxide, preferably less than 0.1 mm thick, and most preferably 1-20 microns, completely covers the removal layer. The tin dioxide layer, or the removal layer, is covered with a thin protective coating film of conductive fluoropolymer plastic. Preferably the grid cores are of expanded aluminum metal.
