Abstract
A device to focus to a point parallel electro-magnetic or sound waves, eg a solar power station, that consists of a reflector curved in one direction to a parabola, that reflects incoming waves onto a second reflector which is also curved in one diection to a parabola. The two reflectors are so placed so as to concentrate the incoming parallel waves to a point focus. The second reflector, unlike similar devices, is so mounted that its focal line makes an acute angle to the plane of symmetry of the first reflector. The device may be mounted on a mechanism to allow the device to track the source of energy, eg in the case of a solar power station the sun. The device can be mounted so that as it tracks the source of energy the focal point remains stationary. The operation of the device can be reversed to create outgoing parallel waves of energy from a point source.
