that's remarkable that so much energy is, is wasted. streetline has looked at the problem of parking, which has not been looked at for the last 30, 40 years. we wanted to rethink that whole industry, so we go and put out these sensors in each parking spot and then there's a mesh network that takes this information, sends it over the internet so you can go find exactly where those open parking spots are. the collaboration with citi was important for providing us the necessary financing; allow this small start up to go provide a service to municipalities, citi has been an incredible source of advice, how to engage with municipalities, how to structure deals, and as we think about internationally citi has been there every step of the way. so the end result is you reduce congestion, you reduce pollution and you provide a service to merchants, and that certainly is huge.
