For example, at the moment I'm working on membrane technologies, not the membranes themselves but how to make holes in them. We can use lasers to drills tiny geometrically spaced holes in special membranes. Nanometre sized holes space just microns apart. But to be commercially useful you need ways to make this stuff by the square kilometre, at the moment the fastest we can go is about 2.5 Million holes per second, and that sounds like quite a lot. But when you are talking about nanometre sized holes spaced micrometres apart it's only at best a few square millimetres per second! That's at least two or three orders of magnitude away from being useful for industry. Yet there are people out there now selling this technology to politicians as the solution to energy storage or generation.
I did the sums the other day, if I can go at 2.5M x 50nm holes per second, at 1um spacing, that is 111hrs to make a 1m² sheet. I can add some more lasers, let's say 1m² / hr is needed so just use 111 lasers. The laser I use is worth US$1.3M a piece!
