A great acheivement, and it must be absolute fun to drive around, dodging the occational rogue streamer from the mother coil. Cheers, Finn Hammer
Thanks! The fun part for me is realizing that the screaming motor is driven by something as ethereal as an ambient electric field.
The rogue streamers aren't really an issue; they're short-lived, and so far haven't come close to the roadster. I suppose if they did connect I might lose some coil components, but I have spares. The new aerial shields the driver quite well; I can't feel the e-fields at all, whereas with the smaller old one I had to wear heavy gloves!
I do think it would be more interesting to have a serpentine track rather than just always turning in one direction. So when we set up outside again, we're going arrange a 400-500ft long track that weaves about around the coil. A little more of a technical challenge as the range and direction varies. From the msmts I've made so far, should be no problem to get sufficient field coupling across a track of that size.
Also hoping to get more folks to put together some prototypes. There's one fellow so far, who wants to convert a Razor 'crazy cart' to wireless.

This one includes a bunch of improvements over the first one. Lower rolling resistance, better drive ratio, and better tuning and coupling for the onboard Tesla coil. All of the small improvements had a much bigger impact than expected: https://youtu.be/NfKOD0XqR14 There's some wireless history at the beginning, test starts at 2:22. Cheers, Greg
