If you're interested in cars that can run on water, you may also be interested in news surrounding a company called EEStor that claims to have created a supercapacitor capable of rendoring current battery technology obsolete. For example, the claim is they have technology you can charge an electric car for 5 minutes at a cost of $9 and then drive that car 500 miles.
Many news outlets picked up the story and so I decided to create another blog devoted to it.
Here's the blog. I've included links to articles on CNN, New York Times, etc.
