And you think its going to sit there just working for 25 years without maintenance? And yea if there is just 1 crane in the world that can do what you need to do. Expect to pay a perimuim, and have very long lead times. don't forget the expensive underwater cables as well.

I approximated the bay as a triangle so its half the volume. 2.5m of height is 1000kg*g*h for a potental energy of 24500J per m3. That is far less than .272kWh. 1kWh is 3.6MJ. So you over estimated the potential energy of a m3 of water by a very large factor. Also where did 100 million come from?

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.

It is based on a bit more than 2 things. Early elemental abundance, cosmic microwave background radiation, large scale structure or lack thereof... etc.

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.

Data caps? What century are you in. I haven't had a data cap on my connections since about 2000. 20Mbit down, and 2Mbit up. No limits.

Interesting. And what about heat generated from the Eric Derexlers machines? That always seems to be ignored or estimated at very low levels. My BOTE was some portion of inter atomic bonds, ie ~1eV or so, and that results in quite a bit of heat.

Diets and supplements is 10B a year industry and won't go away anytime soon. Also don't forget that average effects is not the same as specific effects. We know that metabolism variation among individuals is pretty huge.

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.

Technospeak in star trek is called techobabble.It is actually a thing, about mixing words that make no sense at all, to sound technical. It has less chance of becoming tomorrow future reality than Harry fucking Potter.

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.

the electric sun theory explains exactly nothing. The electric universe theory explains even less. Your explanation makes less sense than the star trek technospeak.

Its uses the new H26 whatever codec and it has over 50 patents claimed. That is what licensing.

We will now have world peace since you sorted that out.
