Because the car's factory engine is still powering the vehicle, all the car's original accessories still function. The radio, air-conditioning, power windows and safety equipment all work as they were designed
The original 1990 Mercury Cougar XR7 uses a supercharged V6 (the LS model was not supercharged), which makes it an ideal donor for gasification conversion. The supercharger forces more gas into the engine cylinders, resulting in a wood-burning car that feels more like the gasoline powered vehicles we're all used to.
The car is still using an internal combustion engine, but it's not direct combustion like a gasoline powered car. In the Beaver, the material can be burned more completely because it's burned at a higher temperature than gasoline burns inside the engine of a modern automobile. This makes the wood burning car cleaner because the fuel source has been burned almost completely, leaving no ash or particulate matter.
There's even a way you can use garbage to run the Beaver. By soaking any organic material in water, even garbage, then using a press to make bricks, those bricks can be loaded into the gasifier and will run the car.
It may come as a surprise to some that the idea of running a vehicle on gasified organic material isn't new. During World War II many buses, tractors and even personal vehicles throughout Europe were powered by wood/gas generators. The downside is that the amount of energy stored in a wood pellet isn't nearly as much as that stored in gasoline. A wood burning car might not be as quick or powerful as a gasoline powered car, but, add it to the list of intriguing alternatives to burning fossil fuels.
