Ok so, Orbital Marine Power is actually pretty interesting. Harness tidal energy generated by large objects orbiting the earth I.e. the moon, and convert it into energy. Also happens to look fantastically sci-fi though, kudos

It’s interesting they use a model where they tie down the floating turbine to the seabed, but less capex than building a whole off shore platform. Also floating means that it’s easier to maintain, no need to submerge to do maintenance, also can be a boat so it’s moveable. Clever

The Orbital O2 generates about 2 Mega Watts which is about 2-3 MW is what a wind turbine generates. A 2MW solar farm is about 10 acres ish. 

2MW wind turbine is about ~$8000 per kW, solar is about ~$1000 per kilowatt and falling, wind offshore/onshore is about 2000-5000 per kW depending on the installation

Why would one ever be interested in tidal energy? I think one of the interesting things is reliability. While solar and wind have predictable and unpredictable uptime and downtime, unless the moon disappears, we have predictable energy source. 

The levelized cost of energy (LCOE) is going to have to come down a lot from $150/300 per MWh to about wind energy off shore wind 30 / 60 dollar per MWh prices. Is that possible?

Some interesting companies in the tidal space, but as you point out the LCOE is too high

Offshore turbines are 15MW now
