> It's extremely, extremely unlikely that we're going to beat plants on efficiency of biomass production I'm not so sure this is true. If it turned out that a more efficient pathway is possible with solar energy collection via sheets of extremely pure crystalline silicon (i.e. solar panels), then I would not think that it's strange that evolution didn't come up with it first. Some solutions simply aren't accessible to evolution.
