Tubes is Tubes

Much of the world's food supply is transported via an inefficient, polluting, and dangerous system of highways and trucks. The overwhelming share of the fuel used to move food powers cumbersome vehicles, only eight percent is really needed to transport the cargoes themselves to supermarkets, according to one estimate.

So what's the alternative? Move the whole system underground and set up a "transport industry Internet," says the United Kingdom based Foodtubes Project, a consortium of academics, project planners, and engineers. Siphon veggies, corn flakes, and cans of baked beans about in high-speed capsules (one by two meters) traveling through dedicated pipelines lodged below our cities. And why not? That's the way we transport water, oil, gas, and sewage, isn't it?
