Switchable Magnets.

Here's a video on drilling holes in "Pyrex" with the Porsadrill diamond bit system. A "T" coupling can be added to a cooler recycling tube to replenish water to the outermost boiler. This setup can be turned into a fine piece of laboratory equipment with a few simple modifications. Naturally a thermostat needs to be positioned inside the boiler away from the heating element and cooling inlet and connected to the temperature controller. (See below):

Thanks, that is very nice but probably would not have net usable work out
over the input work to twist the setup....
But  it could trigger something further..
