The first fuel cell was invented in 1838 and this is the tech used on NASA missions. Essentially, it takes hydrogen and mixes it with oxygen to make electricity and water.
Eight years ago, I purchased Stella, my silver green Lexus. In the last 8 years, we have traveled over 137,000 miles at an average of 15.4mpg. At 20lbs of carbon monoxide per gallon, we have put almost 180,000 lbs of carbon monoxide. Sorry to the atmosphere but I didn’t have many choices back in 2007.
