I read this article. Don't you find it more than a little annoying that Mr. Tesla is nowhere mentioned? This is important. No doubt everyone other than auto mechanics and people who like the hear the vroom-vroom would like to switch to electric cars. The problem is there doesn't seem to be eno

I read it but it seemed flakey. This could be closer to scam than to reality. No one really knows the loss-rate of wireless for high power uses or the dangers involved. There is not much reason to suspect that there is a breakthrough here nor that this makes either scientific or economic sen

I see what you mean. I was unaware of their focused beam method. OTOH, Tesla did invent radio as we know it , but no one seems to know that.. I'm not a slavish Tesla fan, but the history is reasonably clear. This system wouldn't solve the power distribution problem either, since the lack of en

They are careful to say it's not CF. Sure seems like it originated in CF methods. https://spectrum.ieee.org/energywise/energy/nuclear/nuclear-fusiontokamak-not-included

Ha! The new and improved new wording is interesting in a semantic sense... but get real... Of course it is the demon cold fusion, but now we can pivot around that stigma and instead present it all in on a different geometry... very little changes but the word salad. IOW it is the same old col

Hi, Consider this, to split a deuteron costs 2.2 MeV. Hot fusion of two deuterons yields about 4 MeV. At best this would never yield more than about a factor of 2and that's not taking into account any of the losses. And those losses will be very significant. 1) Maybe 1% of the electrons wi
