Climate CoLab: MIT's Solution to Stop Climate Change

Any ideas on how to stop climate change? Ideas such as convincing us to eat less meat sound as grandeur as this one from MIT. Christopher Fry, a research scientist at the MIT Climate CoLab, proposed the idea to add installation of personal rapid transit (PRT) systems on densest US. areas.

Fry says: "We can eliminate cars, buses, subways and short-haul airplanes from our urban areas with a grid of 1-mile square cells of mag-lev guideways, 20 feet above a city containing 2 person 'pods’ that are waiting for customers at an average distance of 1/4 mile from every point in the grid. These pods use less energy and money per passenger mile than any practical electric car, bus or rail (light or not) and are safer and faster."

In fact, PRT is already used by NASA, in an experiment called the Skytran, a system of two-person pods attached to guideways above streets and roads. The pods can stop every half mile or so for anyone who needs to get off. Will the government invest in this system that requires a major change and costs in our transportation system?
