After leaving the Grand Canyon, the biotruck green team is traveling through Death Valley where they are experiencing the high and lows. By that we mean that they are at altitudes ranging from below sea level all the way up to 6,000 feet. As anyone that has driven a regular gasoline powered vehicle knows, changes in altitude can have drastic effects on performance. Well with the gasifier, these altitude changes had just as much, if not more effect on the operation of the system. So Wayne has had to spend some time making adjustments along the way. Here are a couple of pictures taken as they traversed Death Valley.
