@rplst8 posted:It's true, there are plenty of lithium batteries out there in many different forms. However, a lot of the things you mentioned are built by large corporations, a few are very large. The drone is probably the most comparable thing to trains. I'm not doubting that it's possible that there might be a line of battery powered trains soon, or even that we may see this become mainstream. I just see it as a potential hurdle, and I think on the fly charging removes most of that as well as bringing a lot of user friendliness.
Absolutely! One of the main things about a system is that it works with a charging track. And that is the only power on the track so that dirty track become irrelevant.
