Scientists from the land of the rising sun closer to beaming solar power in from space

Japan's suns and daughters are becoming quite the great group of suntists. Scientists working for JAXA, Japan's space administration, have announced a major breakthrough in wireless power transmission ... in that they've actually been able to do it with a high degree of accuracy for once. The team reportedly beamed 1.8 kilowatts, enough juice to power an electric tea kettle, more than 50 meters to a small receiver without any wires.

 

How on earth were they able to do it? 

 

 

 

The researchers were able to do so by first converting the electrical signal to microwaves, then beaming them to a remote receiver, and finally converting them back into electrons. This successful experiment is the first time scientists have been able to move electrons over any appreciable distance with such a high degree of accuracy

 

JAXA has also been at work on the SSPS effort (Space Solar Systems) which aims to harness the power of Helios himself and beam it to earth (into a global grid) via microwaves. 

 

 

 

 What's more, these orbital arrays would never have to deal with obscuring cloud cover or darkened nights as their terrestrial counterparts do.

 

 

 

Additional info

 

 

Mitsubishi Heavy Industries has announced that they've performed a successful ground test using technology that will ultimately form the basis for SSPS (space solar power systems). A 10 kilowatt microwave beam was sent from a transmitter to a receiver 500 meters (1640 feet) away, causing an LED display to illuminate upon receiving the electromagnetic radiation.

So many sun puns.

[GuruMeditationError]

tl;dr but...doesn't that happen already? :confused:

quit photon the urge...Ray on the puns fellas

[CtW]

Gotta love that font!

I would be interested in seeing what kind of damage that would cause if it hit organic matter. It would be pretty awful if the space solar array beamed all that power to a city by accident. Pretty much any part of the ems with enough power to make this work would destroy anything it hit. So what happens when a plane passes through the transmission?

[wolfgang]

An impressive step forward. All hail the age of orbital electronic weapons.

I always find it funny how Nikola Tesla pioneered wireless power almost a hundred if not more than a hundred years ago, yet we still have no idea how to make it available to industries or consumers.

that brightened up my day,  and after reading that article I feel illuminated.

 

 

Now on a serious note,  what happens if you get caught in the microwave? radioburn?  sounds nasty.

Thats a good question. But a better one is what happens if one is in the Caribbean and there happens to be a total calypso of the sun? I try to read up on these things, but I find that only while sunbathing can one truly be well-red.

it does happen, kinda although the aiming part is the biggest breakthrough, it seemed impossible to aim.

guess that it depends on what the plane does with it, it might bounce of the beam, making it go around the world or reflect it to the transmitter, which would mean it attempts to send the beam again, if it's able to react to such a situation.

i think it is also dependent on the wavelength of these waves, with the right wavelength they should be near harmless and pass through matter/metal(except for lead)

 

Ion Cannon ready

 

LoIC reporting for duty

 

"converting the electrical signal to microwaves, then beaming them to a remote receiver, and finally converting them back into electrons"

 

Must be joking...

How is that possible?

To produce a current you need a continuous flow of electrons.

And if you somehow transmit them one way, where do they end up going?

From electrical signals to microwaves to electrons? What??

 

i think that the microwaves only carry the amount of energy coming form the signal, where as the receiver mostly converts the microwaves to something more useable, like let's say, heat to boil water, creating steam which makes a turbine spin, to create power. Im not sure if it's able to work such a way but the basic idea is to pass energy form electron group A to electron group B, which theoretically(so far i know/think) should be possible if you pass energy through a transmitter to a receiver, which only act as a link between the groups.

Damnit, selective reading sucks, I read 'land of the midnight sun' and was about to get all patriot up in this bsns.

 

Though, this is hella cool, Japan.

[Nineshadow]

 

Woooo.

[ADM-Ntek]

here some material

but this is what lord Musk has to say

"How on earth were they able to do it?" Sorry, but this pun cannot be forgiven

[atomicmonkey101]

what about all the microwave though? possible issues there? idk, just asking.

[Trik'Stari]

Bad jokes and energy weapons jokes overload....

[LabRat]

that's what the ancient egyptiand used the pyramids for. Now look, it's a desert.

[elfensky]

Why, instead of (trying to) transfer 'electricity' (which is hard and comes at a powerloss, doesn't it?), don't they (simply) but a solar mirror array in space (where there's always sun) and use that to drive turbines?

Save space on Earth + it's still 'clean' energy since the only thing you're doing is heating up water so it (violently) changes to steam and spins the turbine(s)

..

[LabRat]

you know those solar plants with all mirrors focused on a central tower.......... ever wonder how hot that gets and how much of that heat gets trapped in the earth's atmosphere? talk about global warming.

[GoldSrc]

Sweet, that Comic Sans tho.

Yeah no, don't bring conspiracies here please.

[kuddlesworth9419]

Just gonna post this graph here to correct the misleading graph in the video.

conspiracies..........no, just a little humor.

[Bsmith]

as long they don't bounce of things(example airplaines) there shouldn't be any issues.

don't worry, those take time to charge up.

the problem would be the heat going form space to earth, the atmosphere deflects alot of the heat, absorbs a part and the heat get's trapped.

to be a bit more exact, the ozonlayer contains O₃ when being hit with radiation and heat of the sun the particles split in oxygen (O₂) so simply said  2 O₃ --> 3 O₂ and the other way around due to the lack of other elements, increasing the heat in that area would make it harder for O₃ to form and thus decreasing our protection(ozonlayer hole problem)

 

you know those solar plants with all mirrors focused on a central tower.......... ever wonder how hot that gets and how much of that heat gets trapped in the earth's atmosphere? talk about global warming.

 

if im not mistaken they reach roughly 500^oC, atleast enough to melt certain salts, but since it uses heat that's already inside the atmosphere it hurt's less for the envoirment, the only thing they actually do is focusing the light/heat into a single point where it normally would be spread over an area.

 

Just gonna post this graph here to correct the misleading graph in the video.

 

thanks for posting this, gives an idea of how "stable" the envoirment is by it's self, if you look at this it might even raise the question, "does humanity really increase the effect of global warming?"

opinions on that are pretty broadly spread across the board.
