he believed we could harness hydroelectric, geothermal and solar energy to power the world for free. In theory we can and we do already to some extent except people like making money so it's not really free. He also believed he contacted aliens.
Perpetual motion is never going to be possible ever because of everything we know already. Tesla certainly didn't believe a perpetual motion machine was possible because he had a good understanding of physics.
Where can I learn more about time crystals? what is that a quote from?
Google, quantum time crystals.. It's trippy, as is most of the quantum stuff. It's interesting how perpetual motion could not even take place in a "frictionless" vacuum apparently due to decaying atoms exerting a force or something. I'm actually not that sciency to be honest I'm more curious about the nature of consciousness and it does seem the only way we can actually know something of the outside world is to know the nature of consciousness because the two are inextricably one and the same, science is only really beggining to realise objective reality is essentially made of consciousness. I do think alternative energies are purposefully suppressed and that there is untold amounts of useable energy in the atmosphere, the torus, van allen radiation belt (which has never been passed by man and probably not even machine).. I do wonder about what secrets are being kept from us in Antarctica, I think it's the only treaty that has never been broken...
I don't google things

There you go, the laws of physics are inviolate.
It is perpetual
But you cannot make energy from their motion, E=MC2 still applies.
Did you read about the ones they created? they required massive amounts of energy and only exist briefly.

There is no model of these things where they can be used for a perpetual motion machine. They explicitly say that energy is conserved, as it always it. If you want free energy buy some solar panels or a micro hydro unit, build or buy a biomass gasifier, time crystals and geet engines are not ways to generate energy.
"Tesla envisioned a very long bundle of metal rods, extending from the earth to outer space. The earth is warmer than outer space so heat would be conducted up the bars along with an electric current. Then, all that would be needed is a very long power cord to connect the two ends of the metal bars to a motor. The motor would continue running until the earth was cooled to the temperature of outer space."
that would probably work, but the question is how efficient would it be?
space and earth are about 60 miles apart vertically and a rod of a certain width can only conduct a certain amount of heat.
It would take either some very large rods or many masses of them.
I think we have many places on earth where we can find temperature differentials that are closer together
A lot of people heat their homes with heat pumps that work on a similar principle but by putting pipes into the earth or a body of water where it is warmer.
Thermoelectric generators that generate energy when exposed to different temperatures have been around for a long time, that's a real technology that you can experiment with at home. the problem is they are not that efficient. They are used in cheap 12v electric coolers.

none of these things are free energy though, Tesla would be exploiting the energy in the heat of the earth like geothermal plants do now.
