'A skateboard, with a boost"
This ted talks was about a battery powered skateboard. This is an alternative to driving to get around the city and neighborhood one lives in. It is easily portable and is not a threat to the environment the way a car is with its pollution. And while I know this is not the alternative for everyone (like old people or people that find it dangerous), it could definitely work for some people, and it looks like a lot of fun. I really liked the innovative idea from this Ted Talks and would love to cruise around on one of those skateboards.
