"power-beaming technology"


Sarcasm?

Even uBeam does work, it's just not very efficient


I have no doubts beamed-power is possible, I just assume it's effectively an energy weapon and the real magic is at the receiving end harnessing the power without getting destroyed.

But if you aim it somewhere other than the receiver, it's a weapon, no?


I'm not convinced. I forgot the exact numbers but when I was trying to look at studies 5G alarmists cite* with an open mind some Energy Densities in question (being applied to animal subjects) were stronger than standing in front of one of those enormous ballistic missile tracking phased arrays (Which given the subject of this thread are also used for tracking satellites)

* My absolute favourite one was "Sleeping next to a mobile phone is correlated with lack of sleep" hmmm I wonder why

Thank you for implicitly putting me in the company of 5G alarmists.

We're not talking about 5G here.


It's an extremely inefficient weapon, is my point. Sending energy from orbit to earth sufficiently strong to kill someone would need something like thousands of gigawatts as a point source I think

It doesn't need to kill people to have utility as a weapon.

Just look at how the unexplained alleged "sonic attacks" on the US embassy in Cuba played out.

I also presume there's potential for damaging sensitive electronics.

I'm not in objection of any of this, it's a military mission in nature. It just seems obvious to me that anything capable of beaming useful amounts of energy from space to power drones or anything portable on earth also has potential for direct use as a weapon. The energy density must be relatively high for things having such limited area to collect it.


A sufficiently large antenna would reduce the power requirements significantly.


I think the expectation is that a deployed system will be used to keep drones airborne longer.


Kind of a useless thing to say, no?


it doesn't have to be efficient, it just has to keep drones aloft indefinitely


uBeam works only as the longest-running scam in the Sillicon Valley.

But workable options are in fact possible when you switch from ultrasounds to beaming EM radiation.
