Sorry about that - it also appears my resend as text failed. Some days
it's not worth posting. :)
Here's what I wrote earlier:
Hi Dennis,
This had been discussed at some meetings prior to my joining the group.
The biggest issues with the front mount are safety and EMF emissions. If
you have the bottom mount, you have the entire bottom of the vehicle
protecting live objects. The vehicle also acts as a shield, keeping the
emissions within safety limits.
You won't have the ground clearance issue if you design the vehicle with
this in mind. We've also done attachments to vehicles that do not
interfere with ground clearance.
Not sure about the 44Hz, that's not my area of expertise (I'm the
communication guy for our team) - it appears that 85KHz is going to be
the standard worldwide.
Completely agree that out-of-box thinking is much more fun. :)
Cheers!
P.S. Had to scrub the HTML out of the response - sorry.

Peter,
Looks like you last post didn't work...
I'd be interested to know the answer to Lee's question, though in practical
terms I can see the appeal of the road-based solution. As far as that goes, is
there talk of being able to lower the car coil or is it assumed it will be
fixed? If objects getting in the way is going to be a problem then I can see
something will have to be done to prevent it - perhaps a deployable skirt to
keep things out. If you're going to do that, you might as well make the coil
itself lowerable and get the bonus of more efficient and reliable power
transfer.
Not wanting to shoot your work down but I am reminded of (I think it was) Lee's
idea of using an auto engaging charger connection which would be much more
efficient, much cheaper and only marginally less practical. SOmething like the
airborne re-fueling system is what I had in mind. MW
