Recharge from WiFi?

[Murley]

A wireless charging mat is a totally different and VERY practical technology. You could build it yourself and its not based on radio waves

Ahh OK, thought it was just a small step for man etc etc

[=Stevo=]

one small step for man, one giant cancerous tumour for mankind

Tesla had wireless power working in the early 1900s.

Suddenly his funding from JP morgan dried up when they discussed the issue of how to meter/charge (as in $$$) it....

There was a guy in Canberra who harvested power through induction coils in his walls picking up energy from the nearby 44kw low freq. Naval transmitter. Of course he didn't factor in the normal output was something like 10% so when they ramped it up to full power, his house burnt down...allegedly

HMAS Belconnen. Amazing place, did a tour there with my dad in the 90's (he was ex-navy radio/radar).

250kW or so 44kHz transmitter, huge power. The place was full of capacitors the size of 44 gallon drums. It was held together with wooden dowels, as the magentic fields induced would rip nails straight out of walls.

Submarines could pick up the signals in the Mediterranean.

HMAS Belconnen. .

Actually NTS Belconnen as it's an out station of harman same as bonshaw receiving station.

I was stationed at 'Bells' for a couple of years and can tell you some stories

But you're quite correct. It was 44khz not kw. My bad. All the emf has fried my noggin. :p

In a similar vein... wireless electric bus:

Electric Bus Charges Wirelessly?!





edit:
as stated, wireless power transmission = inefficient. however, if you can get enough/excess of power via clean methods (solar, hydro, wind, whatever) then who cares how inefficient it is?
