Biological Fluid Dynamics: Swimming at low Reynolds numbers.

An electric generator using imploding plasma dynamics for generating electric energy from fuel energy, which includes a substantially cylindrical vortex chamber bounded by a cylindrical chamber wall having an axis, an inward curved fuel inlet end wall, and an opposite inward curved exhaust end wall; a shroud surrounding the vortex chamber forming an air space between the chamber wall and the shroud; at least one air inlet entering the air space at an angle tangential to the air space; air compressor means fluidly communicating with the air inlet for injecting air into the air space; fuel-air mixture injection means disposed in the fuel inlet end wall; a mixing chamber in the fuel-air mixture injection means for mixing fuel with the air fluidly communicatng with the air space; a plasma expansion cone having an inlet fluidly communicating with the mixing chamber for receiving fuel-air mixture from the mixing chamber; ignition means in the plasma expansion cone for igniting the fuel-air mixture, and forming at least one imploding plasma vortex in the vortex chamber; and electric energy take-off means connected with the vortex chamber for taking off electric energy generated by the imploding plasma vortex.
