Mr Couch, would you please could you please cease and desist with all this off-topic nonsense? Your attempts to hijack this forum are not appreciated, nor is your persistence which is nothing more than flame-baiting.
While the devices you have been mentioning may be of interest to you and a select few within this group, they are not of interest to the majority of this group. If some people have unfortunately felt it necessary to lower themselves to conduct similar to your own, it is because you show a complete and utter disregard for basic 'net etiquette and continue to post message traffic that does not belong here. I, like many others joined this group to learn about the design and construction of the multi-machine. I believe the vast majority of us have plenty of ideas on how we intend to power our device.
Pat has been including information on powering various devices because it is in keeping with the original concept of the multimachine - a modern machine tool made primarily with parts from commonly available scrapped equipment in poor and un/under-developed countries. The devices that you have been trying to press on the group are neither practical nor affordable to the people whom Pat is trying to help.
Due to the work Pat has done in Africa, he has seen the need for some things that we take for granted like refrigeration for blood supplies or vaccines. While off-topic from a strict interpretation (non-multi-machine), ideas were solicited from the group with the understanding that it would be to be implemented in the country where Pat has been working, with cost and availability of parts/materials being one of the prime considerations. Again, the ideas you have mentioned do not meet the criteria of the problem since in many if not all cases your ideas include materials that are not commonly found, are cost prohibitive, or require advanced capabilities beyond the current state of the art in the part of the world Pat is working.
While there is probably sufficient interest to warrant a forum for the ideas that you have brought up, this forum is not that place. You have been invited to start your own forum, or join one with like minded individuals.

The Tesla Pump is supposed to be the very most simple, efficient and useful pump in the World. No valves needed. Just a pack of disks on a shaft with an input to the middle and an output on the outer edge.
