An absolutely stunning concept.
How much would it have cost though, realistically? Plus the upkeep.etc etc
It's a nice idea but but practice? Likely not.
They do need to sort out Hammersmith though, but it seems the government doesn't wish to fund it. Not sure why not, maybe it's a pettiness thing against Kahn.
However the government is willing to pay something like £80 million for a new a120 option which just so happens to afford the opportunity to build god knows how many new homes and to serve a waste incinerator
