Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Article is a little light on details but I was wondering at the tech... the losses... the range...

Anyone any better info?

We have uWave towers all over this country, beaming line of site communications data from hilltop to hilltop, as a tech I used to help install and maintain them. Powers were a few tens of watts, tight beams, large circular focusing antenna. Largely replaced by fibre cable now.

Reading this article last week made me laugh, high tech version of snake oil; the costs would be prohibitive and dangerous at high power levels, end to end efficiencies would be very low.

More cost effective to pop up some PV arrays and a battery bank.

Hahaha. Yep, saw this last week linked from another web site I follow. The web site Wasn't so much about the process, but more about how the Government's 'Tech Development' department was gullible enough to throw tax payers money at the idea. Another Martin Jet Pack

a bit like the HYPEerloop then... and solar roadways... lots of well paid experts with bigger wallets than experience/expertise, well to the left of the DK curve.

Any "star trek" tech gets a raised eyebrow from me. Any energy transference not operating in a vacuum will have enormous losses over distance, and even then if the beam confinement is crap. Even the super confined laser they fire at the moon is almost a mile across when it hits the surface. Agreed it's a big ask to do a quarter of a million miles and way greater scale than anything here but ...
