Energy from vacuum and plasma

The discussion about the extraction of energy from vacuum has been going on with varying intensity for
more than 100 years. In this context, it is interesting to note that Tesla already in 1892 came up with its now once again increasingly noticed prophecy:
“Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe.” ..
….
“Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain;
if kinetic – and this we know it is, for certain – then it is a mere question of time when men will
succeed in attaching their machinery to the very wheelwork of nature. ”
By Nikola Tesla
From “Experiments With Alternate Currents Of High Potential And High Frequency” (February 1892)

After many years in the scientific shadow, in recent years the interest in clean and unlimited energy from vacuum and plasma has for obvious reasons come more and more into focus. Most famous are, of course, the extremely costly and yet completely fruitless attempts to move the sun to the earth and create electricity with the help of hot hydrogen plasma. Thankfully, several companies and institutions have long chosen to try completely different paths, and some now actually seem to be approaching their goals in different ways.
Several have already announced that they are planning demonstrations of environmentally friendly and highly efficient energy recovery (heat and direct/indirect electricity) from naturally delimited, medium-warm plasma where hydrogen in various forms plays a crucial role. However, the way in which these plasmas are handled in more detail and how close to a real commercialization one has come is still unclear and also differs considerably between different actors.
Here’s a current interesting example while this innovative company has chosen a different path.
Another supplier working with the direct generation of electricity recently promised an online demonstration of their first product on November 25 this year.
