Recently, the Germans have developed a solar system to convert water and
CO2 to 80 liters of diesel fuel per day. If you have a diesel van this
could be a real boon. Thats approximately 20 gallons of diesel fuel per
day! Given the additional mileage you get with a diesel the could be a
wallet saver. You could run around a week on one days solar production,
building a daily reserve of 20 gallons a day. By weeks end there would be
enough for a serious trip and other things. Anyone looked into this?
