It was pure coincidence that aroused Hans Weigele's interest in pyramids.

A TV programme sparked off his professional curiosity when he realised that the solutions presented to explain the construction of the Egyptian pyramids were unsatisfactory. On the one hand, the concepts had not been fully worked out, since the problem of how to build the top, particularly in relation to the final capstone, or pyramidion, was not even dealt with. On the other, the proposed construction processes were so complicated that they were not worthy of consideration as realistic solutions.

For example, in the case of the ramp theories, the total building involved in constructing the ramp would have been about three times that needed for the actual pyramid. After the pyramid was completed, it would have taken decades to dismantle the ramp, and yet no trace has ever been found of such a clearance process.

Hans Weigele was used to constantly having to find solutions for technical problems throughout his professional life as a mechanical engineer, and so he wanted to find a satisfactory answer that was both practicable from start to finish and also in conformity with the state of technology at that time. An analysis of the technical possibilities of the period soon showed that, apart from gravity, the only resource available was muscle power. Therefore the key to a successful construction method had to lie in making use of gravity.

The solution for a viable technique - called the gravity lift technique - is based on two factors:

That men carry up to a target position the equivalent weight of the stone block that is to be raised, in small, manageable portions.

That the single small weights, collected in a counterweight container, move downwards in accordance with gravity, causing the stone block to be pulled up to its target position on the working level.

The fact that a construction method works in theory as far as the laws of physics are concerned does not necessarily mean that it will work in practice. Dimensions, weights and forces, as well as the equipment and tools required, have to be adapted to a human framework. Time, in this case the lifetime of a pharaoh, was also limited. Only money was no object.

The task was to find a way of combining gravity and human work in such a way that a satisfactory construction method could be developed.
