Bacteria- devourers of metal

What once caused so much destruction and loss is finally bringing benefits to people. Corrosive bacteria have been known since the XX century when they were thought of as a menace but now, after a small genetic adjustment, they began to serve humanity.

Now you do not need to waste time on the complicated and expensive dismantling of old railway bridge pillars. Special robots apply a solution that contains bacteria-metal eaters, and after a while, without noise, dust and unnecessary costs, the old bridge pillars will disappear without a trace. Also, useless railways are disposed of the same way. The ecological balance is restored thanks to modern technology.

Luke Jost This would be great until some terrorist or crazy person finds a way to weaponize this technology. 06 Feb 2019
Dayton Sigurdsson Also wouldn't you want to save those materials for use in future projects? Waste not, want not. 06 Feb 2019
Will Longaphie Bridges have to collapse. It won't be anywhere as "without a trace" as you may think... certainly not without damage on some level. 06 Feb 2019
DJ DRAGON There is a thing called "self-repairing cement". It uses the same kind of bacteria. It is true, Luke Jost, that it could be weaponized, but it could save millions, if not billions of dollars. It would also save a lot of resources, because concrete would be used to fill in cracks and things like that. 06 Feb 2019
