Trondheim is tiny – at least to someone who lives in the shadow of London. So it was eye-opening for me, over four short days, to immerse myself in the fully formed tech scene of a region with a population 2% of that of London’s.
Ocean Space Research at Marintek
Ocean Space – I’d never heard the term before so it took me a moment to understand, that as opposed to outer space, this refers to the vast unexplored regions below the sea-line which we know less about than the surface of the moon. This is the heart of what Marintek do, and they were the hosts for the science working group meeting I was there for, but more about that later. The work done at Marintek is fascinating, but I will limit it to my 3 highlights:
- Ocean labs and towing tanks are used for simulating conditions at sea, for example, oil rigs in the ocean. Yes the tanks are bigger than swimming pools. Yes they could generate all sorts of waves. No we couldn’t swim in them (or take selfies for that matter).
- Floating wind turbines – I heard about them first here – harnessing wind power in the deep sea, amazing!
- Cavitation tunnels – first the science lesson: air bubbles under pressure actually boil at low temperatures, causing implosions aka cavitation – how great is that? So great, I’m linking to this video again so you don’t miss it. Well, actually it’s not so great for badly designed propellers. Luckily this can all be tested for in a cavitation tunnel.
The icing on the cake for the visit was hearing about the plans for a bigger and better ocean space centre, opening in 2020 (assuming the politics all works out as planned). Who knows what else the great depths have to offer mankind?
