Peter Lindemann talking about different designs for an ambient heat engine, and a few different variations of the same concept.
The state-of-the-art would be a refrigerator or heat pump that would only require a heat exchanger outside to absorb heat, but otherwise would run for 'free' with the only biproduct being refrigeration.
Peter Lindemann talking about Tesla's Ambient Heat engine and various potential ways to accomplish it. Got some good ideas from this one, though much is repeat of older material.
Very good chance I will be building a design based on this concept within the next few months😁
Experimental spark-gap radio transmitter (very old style)Tesla magnifying transmitter (to work in tandem with the radio transmitter to see how far a small signal would propagateGEET engine (supposed to run on a mix of gas and water instead of gas alone). Probably nothing fancy but it's always nice to see people actually building stuff.Bedini Ferris wheel (part of the 'free energy gimmicky thing. More fancy+flash than practical invention, but I am curious to get a few measurements on it to model how it works from a Tesla-Steinmetz Parametric Variation POV)Another smaller bedini-type motor
Didn't get any good shots of the Tesla Turbine presentation, but Jeremiah's got an enticing setup that I did spend much time replicating last year.
