I came across an article on a mechanism that can extract hydrogen from normal gasoline, a process that could greatly increase the potential for fuel cell-based electric cars. The item, called a reformer, would allow for twice the efficiency of existing gasoline-based engines, produce half as much carbon dioxide, and would go a long way toward solving the fuel distribution problem. Current reformers are too large to feasibly be used in existing electric vehicles, and there is a 15-minute delay between refueling and producing enough hydrogen.
