So this is a pretty interesting one, I have serious doubts about this one, but here it goes. As we make our way to a oil-less future, hopefully sooner rather than later, the questions remains: what do we do with all the old infrastructure? One possible relic is the gas tanker. Now the Gas-off, no pun intended, of the internals of the tank leave me very skeptical. Perhaps a good scrub, then a grinding of the top inner layer might do it. But potentially we could be left with 10′s of thousands of these tankers, here is Aristede Antonas take on how to upcycle these.
