Patent CA-2605835-A1 (CA)
Inventor: MACKELVIE WINSTON
IPC: F03D1/04
Filed: 2007-10-03
Abstract: The present invention is a method and apparatus to increase air speed through a turbine such as in a wind power generator. The method comprises creating a low pressure area behind (or, downstream) of the turbine so as to cause the wind entering the turbine to be accelerated thereby adding torque for the turbine to turn the generator. The apparatus comprises a generally conic shaped, open-ended hood that extends behind the turbine to act as an airfoil and so cause an increase in air speed along its lengthening outer surface, which, in turn, lowers the pressure in the interior of the hood. Wind will thus be 'drawn' into the resulting partial vacuum thereby raising wind speed. Also disclosed is a mobile use where a turbine generator is shrouded to the the rear of a vehicle with an opening to enable fir flow to enter the shroud and drive the turbine as the air seeks the naturally-occurring low pressure area to the rear of the vehicle and shrouded turbine.

IPC: C08F2/00
Filed: 2006-05-29
Abstract: Conducting polythiophene films are produced by the oxidation of bithiophene or terthiophene monomers using phosphomolybdic acid, wherein the reagents are first combined to form a metastable solution, the solution is then cast as a film, and polymerisation ultimately initiated by evaporation of the solvent The equivalent formation of polypyrrole via the oxidation of pyrrole using phosphomolybdic acid has been previously demonstrated, but this approach cannot be applied directly to thiophene, which has too high an oxidation potential Bithiophene and terthiophene have lower oxidation potentials, close to that of pyrrole This work suggests the previously demonstrated method is suitable for general application, requiring only the proper matching of monomer and oxidant redox potentials, and the selection of a suitable solvent and starting concentration Smooth, spin-coated polythiophene films having thicknesses of 100 to 200 run and conductivities in the range 0.2 to 0.3 S-cm-1 have been prepared.
