Those numbers seem off. Lets assume you not cutting it off right out at the sea, but a bit closer in, for the simple reason that a dam 50km in length is well probably not going to work in the deeper areas, ecologically or economically. Closer however we can assume a triangle shape and lets be optimistic and assume 20km wide and somehow the greenies sign off on that (seriously ecologically this is a really hard sell). That 20km wide 20km long with a 5m head. This is very unrealistic, we are assuming we can empty and fill the lagoon instantly at peak head: 20kmx20km/2*5=1Billion m3. Potential energy with a 5m drop, rise x2 drop x2 is 1e11J. Or 27MWh per day. This is no where near 25% UKs power needs. Wiki claims average consumption of 840GWh per day.

Ships cost a bit to buy. But cost far more to run. Running costs is everything. A crew of 50, boom just salaries are costing a lot and charge out rates need to cover the costs when the ship is not in use, and for technical ships crews are typically larger, highly skilled and well paid. It would easily be 100k + per day and wouldn't take much to get it into the 1M per day.

Or perhaps there mega stars theory is correct (whatever its called). It has more metal that expected. There are many things that could account for this. But early on massive stars may have been possible and would burn out very fast into huge supernovae, populating a very young universe with metals earlier than expected.

Personally i can put up with rats in the toilet if i have WiFi.

On a more serious note. It is only the top end expensive places that charge for internet. The backpackers and cheap motels i have stayed not only have free internet, but it was fast as well. Hell even some campsites i have been too have free internet.

Yea alot of the old shit was done to a very low standard. I mean really Shit Standard. These days we demand stuff that is better. Just because its old doesn't make it good.

Sure it may have seemed good the first time because you where like 5 years old. Trek was and always will be "pop" TV and Cinema.

Ya'll hear about the geometer who went to the beach to catch some rays and became a tangent ?
