In his words, "The bucket was moved to different locations to demonstrate the various shapes of the beam from different angles to the target. The beam clearly demonstrates the 'inverse square law'. The energy bounced off the lens can be "tapped" at whatever distance suits the target. This is just as effective either in front or behind the actual focal point. The heat transfer to a can of water was most effective when the beam was spread. A number of experiments were carried out to examine the effects of different coloured target surfaces.

abstract	In his words, "The bucket was moved to different locations to demonstrate the various shapes of the beam from different angles to the target. The beam clearly demonstrates the 'inverse square law'. The energy bounced off the lens can be "tapped" at whatever distance suits the target. This is just as effective either in front or behind the actual focal point. The heat transfer to a can of water was most effective when the beam was spread. A number of experiments were carried out to examine the effects of different coloured target surfaces. I also invented a shaped surface designed to capture some of the energy that is lost through secondary emission. The off set angle experiments showed how the mirror loses efficiency as the angles are increased and the aperture that the incoming energy has is reduced. One side benefit of many was that I have the design for a fixed focal point cooker that allows the pot to remain in one fixed spot while a super-lightweight reflector can be tracked round it to follow the sun. An 'inverse polar mount' is what it is." With some background work provided by Rollins, there may be a new design direction that can be expanded upon, which incorporates a lightweight reflector that can easily change it's postion to the cooking pot for maximum efficiency.
