These are going to become a common sight everywhere...right next to the handicap parking....then there will probably be robotic car parking and shared car(uber, zipcar etc.) parking, compact car parking,,,,let's face it if you expect to get a parking space in the future you'll need to fit into one of these groups....

I accidentally stumbled onto the NASA website and learned that the policy now is to share technological developments and innovation with industry. There are webinars such as the one involving rolling element bearings with a flexible metallic surface. I was surprised to get a call from an engineer after I had put forth a question following the webinar, about vfd induced eddy currents.
