So the LA Auto Show held a design contest for creative new sustainable vehicles, and some of the entrants are pretty insane. The winning entry is a Hummer (crazy, eh?) filled with panels of algae to supposedly offset the carbon dioxide it produces. As much as I want to believe this to work, the biologist in me is pronouncedly unexcited. The algae in something like this is equivalent to a summer puddle, and obviously would never come close to offsetting production and use of a car like this, let alone the creation and maintenence of roads. Some smart people worked on this… now if only they could work on something practical. Check the ideas.
