And you thought your car was cool because you can plug a DVD player into it. Hybrids Plus unveiled a Toyota Prius hybrid yesterday at Colorado State University that has been modified with plug-in technology. While current plug-in hybrids (PHEV, which are all after-market mods) can get amazing mileage numbers – Hybrid Plus' Prius gets 125 mpg – what's really cool about the Hybrids Plus plan is the possibility of Vehicle to Grid (V2G) technology.

V2G means that the car can draw power from the grid when needed and it can feed power to the grid when it has energy stored up. Hybrids Plus is working on V2G along with the Colorado Governor's Office of Energy Management and Conservation, A123Systems, the U.S. Department of Energy's National Renewable Energy Laboratory (NREL) and Xcel Energy. Xcel Energy and NREL will soon conduct a study to assess the collective effects of thousands of PHEVs on the power grid.
