Thorium power

The most efficient path to carbon free transportation comes by way of small thorium reactors. These are built in factories, assembly style and shipped to the use point. At scale they produce almost endless quantities of electric power and at low cost. This power is used to separate water into hydrogen and oxygen and use the hydrogen for fuel, the only by product being water. Hydrogen can then be combined with carbon dioxide taken from the air to synthesize diesel and aviation fuel. When this is burned the CO2 returns to the air in a neutral cycle. Cars and trucks can still be driverless as technology allows. Thorium is four times more abundant than uranium, produces less dangerous by products and offers walk away safety which prevents melt downs. China has been operating a thorium reactor for the past two years.
