No more plugging in. You just get on the bike, fire it up and everything is getting charged just because you're on it. Dongle free riding for those who must remain connected at all times.

I don't see the need for myself since other than a single GPS I don't gloss over "devices" or heated gear and HUD helmets but it seems like a natural for those who get into that stuff.
Not really, that's a lot of amps to be transfering through induction. Charging a SENA via gloves would be possible but it negates the the 'fraying' connector argument to make the situation considerably worse.

Not to mention the obvious problems with putting inductive coils into something like a glove, that moves and bends all the time.

I like this thought exercise.

Metal-to-metal connections are the most efficient and reliable. Wireless inductive charging is less efficient and can be considerably less so (function of distance to coil, alignment positioning, coil area, etc). Like jumph4x says, getting coils into a glove is a challenge given the bending and conforming that occur plus your hands tend to move around while riding.

To inductively pass a lot of current you need larger coils so a the seat seems like prime real estate. Like fubar929 says, make the seat a large charge coil pad kinda like Aerostich's bead seat (is there really a market for this?!?)

Quilting in photo = pick-up pads (not my ass btw ) which, in turn, are wired to a vest. Gotta run wires from cheeks up to vest. Easier on a 1-piece. A 2-piece suit would still require a physical metal-to-metal-contact connector in the circuit

Bottom line you have to weigh the cost of an expensive wireless charger vs a $1 connector.

What if you are stalked by a Quilt-Fetishist? Some people might get a Charge from those pants that you'd rather avoid.

And inductive coils by themselves are pretty inefficient. Usually, some sort of ferrite core is required which adds to the bulk.

The efficiency of the charger is nice in theory but in practice does it really matter much? It's not like the source (bike's charging system) is often overtaxed and it's also not a race to see how fast something would charge.

So does it really matter much in reality if a metal to metal connection is more efficient than some other means? If plugging in via connectors is idea for you by all means but more and more things are going to way of wireless charging. So long as whatever is being charged is charges adequately does it matter is one way is less efficient than another? If so, then just what happens to the excess energy being shunted to ground? It's wasted. That can't be efficient.

I guess the thread title is wireless charging and I thought for a while how I could make my own for my go-pro. I think the topic morphed into heating gear and now efficiency?

I've never personally seen one of these...

Better, but(t) you still have freedom of movement in rotation. Few riders sit in one place while riding. Anyways I wasn't thinking one giant coil but several arrayed across the charging surfaces.

Right. Losses, given off as heat, are arguably minimal but overtaxing can be a concern depending on the power draw and the bikes output. Inefficiency adds cost and limits design options. For example, you might make up for losses by expanding the charge area - seat space is finite (esp. if you have a skinny ass). Some might suggest adding coils to other areas of the bike like the tank in which case you might end up with this:

Burned up stators are pretty common, especially if you have a shunt type R/R. Under taxing the electrical system causes the stator shunt it's full output to ground.
Most bikes don't have all that much capacity to run gear. Heated grips, aux lights and a heated jacket will put most electrical systems at or above their max capacity.

Your commentary ruins the hyperbole effect of that image.

Sitting on a bunch of ferrite coils would be uncomfortable, I would imagine. And precise alignment of the coils on your gear and the coils on the seat would still be required. Though not comfortable, a single large coil with a post in the middle would probably work best.

Once we can miniaturize super conductors, this will all be possible.

Not any less comfortable than many stock seats.

I dare say, watching some people on long rides slide back an forth and squirm they could probably generate enough energy to charge anything.
