Reinventing the Tuktuk

In large cities across Asia, auto rickshaws (tuktuks) are one of the most important means of transportation. These tuktuks produce considerable CO2 emissions and air pollution, and their drivers are underpaid. Students participating in the Hybrid Auto Rickshaw project sought to cut CO2 emissions by 40%, while improving the economic positions of drivers.

Windshields to Reflect Sunlight, and Perhaps Produce Electricity

The California Air Resources Board will require new cars sold in California to have windows that reflect or absorb heat-producing rays from the sun. Starting in 2012, windows must prevent 45 percent of the sun's total heat-producing energy from entering the car, and the windshield must reject at least 50 percent. In 2016, this increases to 60 percent.

Creating "Cool" Cars

Operating the air conditioning is the largest auxiliary energy drain on cars. In December 2008, DOE announced a project to study and develop thermoelectric heating and cooling systems. As partners in the project, NREL will team up with Ford to research efficient ways of cooling vehicles.
