A gas generator includes an oxygen inlet, a gaseous fuel inlet, a water, steam and/or CO2 inlet and a water borne fuel inlet. The water borne fuel is combusted within the gas generator along with the oxygen and the gaseous fuel to produce products of combustion including substantially only steam and carbon dioxide. The water borne fuel can be a water fuel solution, emulsion, mixture or other combination. The water borne fuel can either provide only a small portion of the total fuel into the gas generator or provide up to all of the fuel input into the gas generator. The combustion products are discharged from the gas generator and then power is extracted, such as through a turbine. The products of combustion can then be separated, such as within a condenser. Carbon dioxide is thus removed and can be readily sequestered away from the atmosphere to avoid emission of greenhouse gases.

Utilisation of geothermal energy in depths above 5 km could contribute considerably to resolving the global problems related to a lack of energy and to glasshouse gases from fossil fuels. The invention describes innovative equipment which makes deep holes in geological formations (rock) by disintegrating the soil into blocks carried to the land surface through the excavated hole filled with liquid, using transport modules yielded up by gas buoyancy interaction in the transport module utilising supercavitation. In an opposite direction—by help of negative buoyancy—the necessary energy carriers, materials and components, or entire devices required for rock excavation, are carried to the bottom. The opportunity to transport rock in entire blocks reduces energy consumption considerably, because the rock is disintegrated in the section volumes only. Some of the extracted rock and material carried from the surface is used to make a casing of the hole using a part of the equipment. The equipment also allows the generation of the necessary high pressure of liquid at the bottom of the hole, to increase permeability of adjacent rock. The equipment as a whole allows by its function that there is almost linear dependence between the price and depth (length) of the produced hole (borehole).

The invention relates to direct conversion of coal into electricity in a high temperature electrochemical generator in a single step process. This novel concept promises nearly doubling the conversion efficiency of conventional coal-fired processes and offering near-zero emissions. The improved efficiency would mean that nearly half as much coal is mined and transported to the power plant, and half the greenhouse gases and other pollutants such as sulfur, mercury and dioxins are produced. It also offers several crucial distinctions from conventional coal-burning processes. Since the process does not involve the combustion of coal in air, it does not involve nitrogen and hence generates practically no NOx. Accordingly, there is also no latent heat lost to nitrogen. In this process, the oxygen necessary to oxidize coal is supplied through an ion selective ceramic membrane electrolyte. The resultant product stream primarily consists of CO₂ and, hence, it is easier and cheaper to capture and sequester, compared to waste streams from conventional combustion processes where CO₂ ordinarily constitutes about 15-20% of the flue stream, in which case it may first be separated from other constituents before sequestration.
