Biofuels could work, but using agricultural land to do it is stupid. We have deserts and oceans to grow bacteria, seaweed, or other fast-growing non-consumables that could be made into biofuel rather than corn.
Of course, the real reason for using corn is because of agricultural lobbying of congress. The real innovation here is that the agricultural industry found a way to latch on to the global warming hysteria. That is the only type of innovation that the government promotes today.
good post, thanks. your comment isn't surprising since the "government" is infested with liberal loons and doesn't look like or operate anything close to what the framers of the constitution intended
