Hi Guys,
After Russell's suggestion of  induction charging for the van, I had s bit
of a look around and although there is a lot of info on theoretical systems
I can't find any practical DIY applications of the principal. As any of you
played with this before and what power levels are achievable?
In principle it doesn't even need to be be two flat inductors, I would be
happy with let's say to have the receiver coil wound around a pipe and
stick the tx coil inside it. Just worried this is just a east of time as
you would not be able to get a good magnetic coupling.
Thank you.
