An electrosurgical instrument that is capable of generating high-quality RF energy carriers at one of three different frequencies and combining any of the three carriers with any one of four electrosurgical mode waveform modulations and selectively supplying the modulated carriers to either a monopolar or a bipolar handpiece. In a preferred embodiment, the first carrier frequency is in the range of about 3.8-4.0 MHz, the second carrier frequency is in the range of about 1.7-2.0 MHz, and the third carrier frequency is in the range of about 400-600 KHz.

A cable carrier (10) has top (18) and bottom (16) longitudinally continuous sides, with one side (18) more flexible and the opposite side (16) less flexible. The sides are made of continuous sheets of material to define a closed tubular shape in which energy carriers can be housed and supported. The sheets may be integral, or have integral parts, and can be extruded. The carrier may be longitudinally openable with a zipper structure (125) to permit loading of energy carriers.

Utilization 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 utilizing 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 discloses a process and an apparatus thereof for low-temperature cracking and high-temperature gasification of biomass. By adopting superheated vapor steam as oxidizing agent and an energy carrier, the process comprises the following steps of: firstly, carrying out the low-temperature cracking on the biomass fuel in the temperature region of 500-800 DEG C and obtaining the crude synthetic gas and the coke without containing alkali metal oxides; secondly, carrying out the high-temperature gasification on the crude synthetic gas and the coke in the temperature region of 1200-1600 DEG C to obtain the initial synthetic gas without containing tar component; finally, cooling, dust-removing, deacidifying and drying the generated initial synthetic gas, i.e., acquiring the pure synthetic gas of high quality. The apparatus mainly consists of a cracking furnace, a gasifying furnace, a low-temperature plasma torch heater, a high-temperature plasma torch heater, a water storage tank,a water delivery pump and a heat exchanger and the like. The process of the invention has the advantages of easy control, low energy consumption and investment cost and high efficiency of cooled coalgas; the generated synthetic gas has high calorific value and does not contain tar and alkali metal compounds. The invention is suitable for not only biomass gasification combined cyclic power generation, but also preparation of biomass liquid fuel.

A process is disclosed process for converting a solid or highly viscous carbon-based energy carrier material to liquid and gaseous reaction products, said process comprising the steps of: a) contacting the carbon-based energy carrier material with a particulate catalyst material b) converting the carbon-based energy carrier material at a reaction temperature between 200° C. and 450° C., preferably between 250° C. and 350° C., thereby forming reaction products in the vapor phase. In a preferred embodiment the process comprises the additional step of: c) separating the vapor phase reaction products from the particulate catalyst material within 10 seconds after said reaction products are formed; In a further preferred embodiment step c) is followed by: d) quenching the reaction products to a temperature below 200° C.
