i bet there ace !

id love to see one in the hands of a Touring Car World Champion !

Just in case people still might be thinking that this is too good to be true.. IT IS TOO GOOD TO BE TRUE!

dont believe the hype.

Batteries rule!

I hadn’t noticed that :D just saw the pinion missing lol!

It’s a shame Speed Passion hasn’t released any more information to help answer all our questions!

of course the power wires have been cut off - it's a wireless power solution :woot: :p :woot:

I like to think I am open to most 'new' stuff,

but I can't honestly see how on earth they can get 'wireless' power? I mean WTF?

does that mean I can tap into another cars power while I am racing? or do they run like bumper-cars with a wire going up to a metal roof?

jimmy 26-02-2008 09:14 PM

sound like a big bunch of bollocks to me

Cooper 26-02-2008 09:15 PM

or 1 big electricity field over the track and the cars all take energy from that, like 'boxing cars' or whatever it's called in english.

LOL dodgems cooper :lol:..

i wonder how it actually works :eh?:

It's actually a very simple: resonance
http://news.bbc.co.uk/1/hi/technology/6129460.stm

Still, I'd like to see it work in RC at high volts/amps

Mutant 26-02-2008 10:12 PM

If there is any substance to it then it will probably be based on the 'WiTricity' principle using resonance coupling.

http://en.wikipedia.org/wiki/WiTricity

It appears that they had a rig a few years back capable of 60W transmission at 40% efficiency, could this new device be a reult of refinements to the technology?

martboy21 26-02-2008 10:12 PM

puzzled...how do you send enough power wirelessly to power a brushless motor/esc? seems against all laws of physics to me,

i mean yeah we have wireless internet etc but that that needs power from both ends to work, router/modem and laptop power,seems weird to me!!!???

Northy 26-02-2008 10:26 PM

It is not possible (yet) for the amount of power we use.

i guess that is why devices are unavailable then............

We will just have to see if anything develops. However It does appear to be theortically possible, and a reasonably 'high power' laboratory proof of concept appears to have been carried out.

dave g 26-02-2008 11:35 PM

we wouldnt need as much power because you wont have cells to lug about,time will tell i spose.

Huw333 27-02-2008 05:09 PM

From what i've read in the articles, people are correct in saying its can be done but only for appliances that require very low power.

It seems to me that Speed Passion have designed this box with an ariel to demonstate what it might look like if the technology actually comes available.

The reality of running a 50A motor from a wireless power source could be possible in the future but it certainly isnt at the moment. Thats just my opinion though!

If you want a simple explanation, the way i understand it, the therory works on resonance. One device would emit a frequency, causing the other to resonate, and generate electricity. Similar to how a speaker can make an object vibrate - except this works on much higher frequencies.

Northy 27-02-2008 05:13 PM

Nothing to see here, move along....

IT IS NOT POSSIBLE.

My bet is on details being released on 1st of April. ;);)

There will be Hydrogen Fuel Cell powered cars first. :eh?: (cool smilie)

IT IS POSSIBLE and whats more is its an amazingly simple principal!

NOT at the power levels we use! :p
