over the top
Look I love Dean Kamen as much as the next guy--- sure the Segway wasn't exactly the "it" we were promised (of course it never got the fuel cells needed to make it a serious machine), and his water tratment systems are GENUIS. But the latest story, about the Kamen making a "Hybrid Stirling Engine Scooter" is stupid. Yes, I said it, it's just wasteful and shows whats wrong with more than 1/2 of the EV "market."
Kamen is now working on a stirling engine hybrid scooter. That means a scooter that uses gas, but also has some hybrid electric motor, and now his fancy stirling engine (which works with TH!NK but not so much on a scooter). Why why why??? There is no need for this.
See, until the police pried me off my electric scooter, I ran around Montreal for years and never once ran out of electricity. That's just the nature of the beats-- a scooter that only goes 75 kmh can not go on highways, hence the average commute on a scooter is less than 30km. LEAD ACID BATTERIES ARE PERFECT FOR THIS! There is no need for li-ion (like many scooters are now selling as an 'upgrade') and certainly no need for a hybrid motor. This is what Yamahaha is said to be doing as well, put out a hybrid scooter. These are BS. There is no need to have both an electric motor and an ICE, you can get everything done on Lead Acid Batteries (and LABats are infinitely more recyclable than lithium, cadmium, little metal hydrides....).
This is the same as the EV industry where people just wont buy an electric car if it only has a 100km range, and I'm sorry for sounding like a jerk, but this is just pure stupidity. People pay no attention to how much they drive per day-- if they did, they would know that they drive less than 50km a day! This means that for 99.9% of your average 2-car owner's driving, simple (and cheap) Lead Acid batteries and a 9" electric motor is all they need! Face it, you're not in college anymore, the Grateful Dead no longer tour, and there will be no big road trip (except for maybe driving the kids to Florida over Xmas).
If one were to convert their car to electric, or buy a preconverted electric, with lead acid, the money they save from EV commuting would afford the commuter to rent a rolls royce for their once annual road trip. And still pundits daliy bemoan the fact that EVs batteries don't go 300 miles on a charge! WHO DOES A 300 MILE COMMUTE????
I love ya Dean, but go back to the water and th!nk cars....
