[Also in Divisions H1 and H2] An arrangement for generating electrical power from a plasma comprises a spherical shell 8 at the centre of which there is supported a ball 10 of plasma-forming material, a plurality of lasers 4 being directed on to the ball and being simultaneously pulsed to create a plasma, the plasma so formed being subjected to the e.m. field of a coil 13 to constrict and modulate it as it flows upwards, and the modulated plasma generating an alternating current in a coil 14, this current being supplied to a transformer whose output may feed an electrical grid. As shown, the balls 10, which may be of deuterium or deuterium and tritium, are carried to the centre of the sphere 8 by an inert gas flowing through tube 11. Water and air-cooling systems are also shown. The Specification describes ways in which the laser beams may be focused on the ball (Figs. 1, 2 and 5, not shown), and the method whereby the lasers are triggered at the instant when the ball is in the centre of the sphere (Fig. 6, not shown). The Specification also describes so called " laser beam compression guns " for producing the pulses of laser energy. Fig. 7 shows an example of such an arrangement wherein laser energy is fed into the end of a tube 71 through a hole in a bullet 76, and is reflected at a diaphragm 73. When the bullet, which has a reflecting front end, is fired it travels up the tube compressing the energy until this bursts through the diaphragm to be focused by a lens 79 on the target ball 70. Several more elaborate examples are disclosed (Figs. 8-15, not shown).
