The parked car is making itself useful these days. Just last month, new startup Getaround launched a peer-to-peer marketplace that dramatically reduces the cost of driving by allowing users to rent cars from strangers using an iPhone. While you're sitting at your desk at work, your car can be out earning you money. Or if you're without a car, you can rent one from someone nearby.
"Since the invention of the automobile, we've been conditioned to think that only one person should own and use each car," says Getaround Co-Founder Elliot Kroo. "Getaround is changing that paradigm by enabling people to access a vehicle instead of having to possess one."
Getaround's latest initiative will no doubt attract legions of early adopters: Members can now try out the $108,000 Tesla Roadster for just $25 an hour.
Of course the Tesla (which is owned by a private individual who wants as many people as possible to experience it) isn't the only car available at Getaround. And other companies are jumping in the EV rental bandwagon, too. Hertz started renting out electric Smart cars in December, and just last week, rented out the first Chevy Volt. And Zipcar has been renting out alternative fuel vehicles for years.













Every year one of America's top New Year's resolutions is to join a gym and get in shape. And every year America just gets fatter. So what if our workout facilities started hitting us where it really counts; not in our guts, but in our pocketbooks?
That's the main idea behind Gym-Pact, a new company in Boston that partners with local vendors to offer discounts to consumers in exchange for weekly workout commitments. If you fulfill your commitment and attend the gym as promised, you get to skate along at reduced rates. But, if you choose to loaf and skip your agreed upon workouts, you're penalized at least $10 per day.
Gym-Pact is the bright idea of two 2010 Harvard grads, Yifan Zhang and Geoff Oberhofer, who were inspired by a lesson from their behavioral economics class: "[P]eople are more motivated by immediate consequences than by future possibilities." According to Zhang and Oberhofer, because many gym fees are paid for up front, people tend to give up on working out fairly easily, as they consider the cost sunk regardless of whether they go. But by instituting an immediate daily cost, the motivation behind the penalty drastically increases.
