By Michael O'Brien / Marketplace EditorToday you can drive your car down Commonwealth Avenue as your vehicle emits tons of exhaust into the atmosphere, continuing humanity's onslaught on the earth's environment. In the future, due to recent efforts by a joint research team from Boston College and the Massachusetts Institute of Technology, that exhaust might be used to power your car's battery. In more technical terms, these researchers have demonstrated a huge increase in thermoelectric efficiency - effectively introducing a new standard for the creation and use of heating, cooling, and power. Though the technology has been around for years, this specific advancement is important because it has paved the way for commercial application - ranging from refrigerators and air conditioners to solar technology to automobiles to semiconductors. The primary ramifications are that the products will be cleaner and will run more efficiently.
