this<\/a>. A bit pricey, but facinating. They claim it can go 62 miles on a single charge without the rider pedaling, but I’m sure those are flatland numbers. I’ll bet you’d be lucky to get 20 miles out of it here in sine wave country. Still, you can supplement that with your own contribution, and it looks like it still works as a fully functional bike even when the batteries are depleted. <\/p>\nJust outstanding. <\/p>\n
Still no flying cars, though.<\/p>\n","protected":false},"excerpt":{"rendered":"
Take a couple of sine waves of differing wavelength and amplitude. Now combine them. The resulting waveform is going to be a lot like your average road in western Pennsylvania, which is any shape but flat. The only time you’re not ascending or descending is when you’re at a standstill.

<\/td><\/tr><\/table>Anyone traveling under their own locomotive power in this sort of setting will quickly come to appreciate just how much energy is wasted getting around like this. When I would hit a gentle downhill I’d think how nice it would be if my efforts could be somehow stored<\/i> for later (for the inevitable upcoming hill) instead of increasing my speed now. When I’d hit a steep downhill I’d have to do the most painful thing of all, which is throw away some of my hard-earned potential energy by using the brake. When I hit an uphill I’d think about all the effort I just threw away, and wish I could recover it somehow. <\/p>\n
