I noticed that the Solar MH could travel a max of 174m ... that's a whopping 281km. I must have mis-heard. I would have thought that it would recharge while driving ... perhaps not enough to be 'self sufficient' & has to pause to fully charge. Might go back & have another listen.
I suppose that like many concepts we will find bits filtering into mainline RVs over time.
I don't think too many of these would survive our famous "tracks"! Smaller remote townships might be on the way out if tourists cannot get there to assist the economy.
Still I guess the designers will have to do some serious thinking shortly with electric vehicles being the preferred option of the future.
