Japan space scientists make wireless energy breakthrough

Tokyo (AFP) - Japanese scientists have succeeded in transmitting energy wirelessly, in a key step that could one day make solar power generation in space a possibility, an official said Thursday.
Researchers used microwaves to deliver 1.8 kilowatts of power -- enough to run an electric kettle -- through the air with pinpoint accuracy to a receiver 55 metres (170 feet) away.

So What you say?

The oil companies will never let it be developed you say?

Suppose someone made it into a weapon...
 
There's not a lot of space in Japan...

;)

I read about researchers doing this some time back. Very cool stuff.

If there was ever a nation that wanted to tell the oil companies to fuck off, it would probably be Japan.
 
They already did this in a Bond movie.

It didn t end well.

Except for Bond; he nailed Halle Berry.
 
The problems are as follows:
1) Distance. 170 feet isn't very long. In 1900, we managed to turn on lightbulbs from 100 feet away. An extra 70 feet isn't that impressive a century later.

2) Energy loss. Telsa had to use 20 megavolts to light his three lightbulbs. This time they delivered 1.8 kilowatts... but how much energy did they use altogether? The article doesn't say.
 
Morgan and Rockefeller put the squeeze on Westinghouse.

The money trails always leads to these families and their circle of friends, the central bankers.
 
I wouldn't say this is exactly a breakthrough. It's been done before. Perhaps not at this level, though 1.8kW isn't exactly a lot of power. Japan uses 100V systems so that's 18 Amps of available current. For reference, most hair dryers are about 1.5kW.

We are a looooong way off from generating power in space.
 
that's the same paranoid language my father uses when he babbles about antigrav. makes me want to punch him, too.

Because it makes the post seem super paranoid. Why else?

Also, why would you want to make this into a weapon? Are we going to slightly shock someone with this power? Imagine the first degree burn blisters and the messed up hair those tucking terrorists would have with a whopping 1.8kW of power running through their body! We'd show those freedom haters, alright!

'Merica, fuck yeah!!!
 
People can already be microwaved from a distance; electrocuting them from a distance would be redundant.
 
As far as weaponing.... It depends on how fast you dump that 1.8KW and how much area is involved at the target. Go ahead.. get in front of a 11.8KW laser and lets see what happens. Or open up your 1KW Hair dryer and grab the coils. You aren't getting 1kw of energy delivered to your head from that hair dryer.

Now the possibility of solar power generation for ground use? Fascinating concept and currently not feasible. But ideally you would use a wavelength the atmosphere is VERY transparent too. Then have a large array to receive the power so that in any one spot the energy density is low enough to not be dangerous. Say just a few watts per Square meter, for example, at 100 watts per meter, a one square kilometer array could process 100MW of power. At that point short term exposure would probably be non-life threatening.
 
I tend not to get my scientific news from anywhere that refers to "space scientists".

Not even close to running some of my favorite industrial strength vibes either.

This thread is a jip.

Tesla was right, guess we should have gone with him instead of Edison.

We did go with Tesla and Westinghouse over Edison. Alternating current as a wide scale distribution system won out over Edison's advocacy of direct current. DC power appropriately reigns over applications where battery power is typically used, but DC power would have been far too unwieldy to run homes and businesses covering a large geographic footprint.

Tesla was working on this in the early 1900. Look up Wardenclyffe. If I remember, he killed one of his assistants with microwaves from the tower.
