I liked his reasoning behind it "I didn't like my devices to be recharged where I couldn't use them"

specofdust · 16th Nov 2006, 11:44

I'll believe it when I can buy it. Wireless power has been attempted for years and no-ones managed it thus far.

Garside · 16th Nov 2006, 12:37

Have to say this is brilliant. Wonder how much train companies will charge to use their recharge service!

The "would" there is extremely important. Just cos they're theorising new ways of doing wireless power don't mean it's about to happen. Like I said, people have been trying it for years, many theories have been made, so far nothings come of any of 'em.

Swafeman · 16th Nov 2006, 12:55

specofdush your so sceptical

wireless pads have already been created, if you'd been paying any attention, you stick your phone on it and itll charge your battery, not sure if you can buy them in this country yet, but theyve been made, and they work, its just over short distances, but its half way there

Buzzons · 16th Nov 2006, 13:27

Garside GNER don't charge for using their plugs on the trains, so meh

DougEdey · 16th Nov 2006, 13:33

Swafeman: Nothing like this at all. This does not require contact, the other ones rely on close proximity to induce a current.

There already have been "invisible" cables where the ground is used as a ground and power has been transmitted, the problem is that it requires a larger amount of power then is feasible.

Damn right wireless power works.

12V 1A at the charger will charge 2 2600mah batteries in 2 hours. If someone professional tried this, I'm sure they'd get much better results.

It's "Massachusetts Institute of Technology" not Michigan.

The sooner the better. I hate all cables with a passion.

You know I though that and thought I must be being thick or something!

Spearhead · 16th Nov 2006, 14:38

id love this if it worked, currently ive got no power sockets in my room or in my lounge (i moved into a shack basicaly

), so wireless charging would just be amazing for me

Godboy_g · 16th Nov 2006, 15:35

Didn't Nikola Tesla come up with a way to transmit power wirelessly? I think I remember reading an article about how he powered a car in this way.

easy mistake, that happens. Although there is a MIAT in Michigan.

How about this, in the early 1950,s a soviet listening device was found in the American embassy in Moscow (later displayed by the American ambassador in 1960). It was found in the emblem of the Great Seal of the United States above the ambassadors desk. At first western experts were baffled as to how the device worked because it had no batteries or electrical circuits. Peter Wright of Britains MI5 discovered how it worked and a copy (codename Satyr) was produced. A radio beam was aimed from outside the building, the power from this signal was used by the device as a power source.

Tyinsar · 16th Nov 2006, 16:08

Tesla would be happy (or feel that someone had ripped off one of his ideas yet again)

I, on the other hand, don't like the idea of yet more unseen things with poorly tested effects beaming through my body.

Confused Fishcake · 16th Nov 2006, 16:43

Why are you all so worried about negative effects? All the designs I have seen are just a transformer with an air-gap - all energy is "transmitted" magnetically. Unless you believe that magnetic bracelets etc work, you have nothing to worry about.

Tyinsar · 16th Nov 2006, 17:51

I don't Know that all the radio & microwave signals that we have around us (& through us) today have any measurable detrimental effects but at the same time I'm just not comfortable with the idea of even more.

Wireless KBs/Mice could become much friendlier.

Any 'spare' power being emitted could be re-absorbed back by the emitter device.

But how efficient could this be? I'm trying to reduce my power consumption.
