	There is also the [http://www.solarfire.org/Prometheus-System-Calculator Prometheus Calculator], written in Open Office Calc (spreadsheet). The calculator is a sort of prototype for the simulator; for instance, the calculator can only give you the ideal inclinations of the reflectors for a given sun angle, whereas the simulator can calculate all the ideal. which is far more powerful and can create the graph sequences of the focal point, seen below.

They are currently working on a larger machine that they estimate will be about 33% less per watt, and run the steam engine seen in the video continuously.
