What is "foodtubes"

Foodtubes is a proposed network of underground pipeline capsules to transport food and other goods. The system would consist of 2m long metal capsules shifting through underground tunnels at speeds of up to 60 miles (100 km) per hour, directed by linear induction motors and routed by intelligent software to their destinations. The concept was initially developed by Noel Hodson and was engineered and developed for use in the United Kingdom.

The Foodtubes group estimates the system construction to cost only $5 million per kilometer (as opposed $28 million per kilometer for 4-lane highways) and claim that implementation of it could save billions of litres of fuel per year, reduce street level pollution and greenhouse gases, and free up congested roads. The group has developed a plan to link all the food outlets, schools and other major buildings in the London borough of Croydon with an estimated construction cost of £400 million and an estimated profits of £80 million per year.
