Sometimes truth is stranger than fiction — and solutions come in a lot of different packages. A group of Indian engineering students were told to make something that had never been made before, so they created a motorcycle that runs on…air. Yes, *just* air. I’m not talking about Hagrid, flying around in the air, or magic in general — it’s simply a motorcycle that runs on compressed air. I can’t embed the video here but you can click here to watch it. The motorcycle is currently pretty slow — it only goes about 18 km/hr (that’s about 11 mph), but it creates absolutely no pollution and it looks like it can be hand pumped. It’s hard to say how long it lasts, but it does not run on combustion at all and I suppose it would be possible to just stop and pump it up again. This is one of the most innovative things I have ever seen — and Marti, just so you know, it was created by grad students. 
Hello Missy , I just read your post on the air bike.
There is also an air car. I wish they had them here so I could get one. This is the website, http://www.mdi.lu/english/index.php
That is totally cool! I want the convertible one.
