brain teaser

have you ever thought of a new way to power cars? comment on what you think. please put the energy type and how you plan to do that

my example is : i think cars should run on water. the cars would run through gears and turn the moater. their would be a bin at the top of the car to collect water. then instead of gas stations, we would have water stations. if any questions about this, leave me a note at the contact me tap at the top of the page.
