Aaron apparently, in his own words in this podcast thinks suppression of technology, at least in some circumstances, is "just good business practice". https://www.podchaser.com/podcasts/the-higherside-chats-27046/episodes/aaron-murakami-jeremiah-ferwer-150784081 Hard to determine who are t...

I think your first pic, of the contact strips, is possibly the best, but I would put them on opposite sides of the displacer, and use a metal wheel as the other side of the connection. I'm worried about the weight that all of this would add to the displacer though. The most interesting thing about ...

Or maybe generate a current within the displacer?

Or maybe the wires could be routed up through a hollow connecting rod:

Maybe transfer the electrical current through via some contact strips ?

Somehow the above scenario seems highly unlikely to me. For one thing, the efficiency of Peltier devices generally is notoriously rather poor. For the above to be true, it would suggest that ALL the heat generated by the input current would somehow only appear on the hot side of the chip. At any rat...

Ah yeah since his previous partner died. But Jeremiah was going in the heated fluid direction before already. ... Perhaps it was the departed partner who was into the ambient heat aspect. In that case I wouldn't expect anything more of interest to emerge from the new partnership. Compress_20240530_...

Jeremiah has been under his supervision for the past couple of years.

Missed one detail. Jeremiah is working with a heated vacuum tank on one side and an ambient condensor on the other. ... That appears to be the case recently, His older videos from several years ago were much more targeted on utilizing ambient heat. I think he's perhaps being taken down a different ...

After reading several articles about Peltier device efficiency and COP, when used as a heat pump, efficiency can be greater than 100% This is because the device is not only moving heat but the applied power is also converted to heat as well. When using it as a heating device, the efficiency will be ...

After watching this video: https://youtu.be/vsTIWhZ-6HM I've been trying to think how to utilize both the hot and cold side of a Peltier device without having to use two engines. Heat pipes? That might work, but kind of difficult to implement and bound to lose a lot of heat in transport. What if, .....

I missed some posts I see. With the vacuum cleaner analogy in mind. I'm not proposing to have the motor/pump pull so hard that it creates a cold vacuum because of decompression. What would happen in you plugged the hose of the vacuum cleaner with your hand and leave a small gap. Air rushes in and y...

In the past I didn't always get what you (Tom) were talking about. But I think I've come to a similar conclusion as you during my recent research. I've been looking into Tesla turbines in great detail and have a configuration in mind that eventually might work as an ambient heat engine. This is goi...

Just thought I would mention, I'm designing a new-ish kind of little butane heat pump to run a Stirling engine. A conventional heat pump is designed for either heating or cooling, but a Stirling engine can utilize both. The problem is, to make cold, a heat pump is designed to "reject" heat...

... "heat of compression" , a misleading statement. No heat involved. ... Your dissertation does not address Work . Seems to deny a work-heat relationship. "Heat of compression" is a transfer of energy. Work input results in an increase in temperature. Calling that increase in t...
