I think, if you live in an uninhabited country, that coastal hydro makes a lot of sense. But at least where most of us live the idea of flooding the coastal plains is a fairly drastic solution, not much different to the threats of rising sea level which may or may not turn out to be significant..
Nuclear power plant of 800 MW shall be adopted for the area of 5 x 5 km ... 64 km square So it have any 3 such power ... but here is 12000 MW of free space for 15 nuclear power plants .. that is the difference, ie 12 will surface to be used for example to residence .. of course, the surface of the sea with swimmers will be pumping big ..
:wave:
Can someone pay me for finding 300 square km of free land in the UK? :lol:

That if to fill all unused spaces up on ships with this polystyrene foam, most probably they stood unsinkable .
Thanks to the fact that it wouldn't be possible to sink them,
a lot of people so that it is possible to rescue.
And next
then to the shipyard it would be possible to tow away
Recently I noticed ,that the aircraft would be very useful by the ability to swimming

tu142 http://en.wikipedia.org/wiki/Tupolev_Tu-142
If such a shortcut poliuretane foam for construction of such parameters:
Specifications specific gravity after hardening 11 - 16 ,3 kg/m3* Base polyurethane Productivity of 825 ml – 66 litres * c 100 mb of the stream about the diameter of 5 2 cm * Pyłosuchość 8 - 10 minutes * Time of processing 15 - 30 minutes * Time of hardening from 5 up to 48 h (full mechanical load capacity) * a free access of air is Necessary. One should not apply foam in rooms closed tightly. Resistance to UV rays weak in outside applications one should shelter the surface of foam from the UV radiation. Structure of cells of c 70 % smoothed, evenly closed cells thermal Resistance after hardening from – 40 ° C to + 90 ° C (short-term to + 140 ° C)
15 bottle give 1 m^3 (1000 litres) cost about 80 $ , this can swimm 1 tones
Tupolew 142 have 80 ton weight 80 x 15 = , need 1200 pieces bottles this foam .
All cost of foam 80 x 80 $= 6400 $.
Whole weight of the foam to allow the total buoyancy such an airplane is 1200 KG
It is only 1% of the total weight of the aircraft.
Wig area is 311 m^2 , 80 m^3/ 312 m^2 = 0,25 m the average amount of surface foam on the inside wings. I think that in this plane is so much unused space.
And such buoyancy of the aircraft would also be found useful for Airbus over the Atlantic, as well as the Boening over Hudson.

If my ideas and name were not banished, supposedly in the interests of different groups, it can now this flight Malaysia Airlines Flight 370 would have ended differently .. no but tell me not to fight with the Windmills of Don Quixote .. I think you are the wiser and better knowledge of what to do .. instead of listening what to do .. I wonder if those who are on hand this banning, feel at least some share of responsibility for what happened ...
Anyway, but now it comes to airplanes .. According to my old calculations in 1 square meter for the TU 142 to have a buoyancy should be an average of 25 cm of foam .. or on each side of the plate from inside the 12 cm ... It's such a little thicker siding ..

Hi
We have drifted of the subject here
"That if to fill all unused spaces up on ships with this polystyrene foam, most probably they stood unsinkable ."
My criticism of this idea "Also off the subject". Even more TOXIC SMOKE in case of a FIRE.

I subscribe to this thread and have always enjoyed your posts, so keep them going.
Regarding the use of foam to prevent aircraft from sinking when lost at sea, I don’t have the statistics, but anecdotally, I assume that most deaths are not due to drowning, but due to impact, or other high energy violent endings. I believe the scenarios you are discussing likely have adequate solutions in place (life rafts, etc.).
I think an excellent area for the use of that type of foam would be in help reduce the death toll for passenger and roll on/off ferry accidents. These seem to happen in rough seas, or in overcrowding conditions with sometimes large loss of life.

Thank you very much Richard for a good link and my subscriptions. I Normally you need only the broad outlines of the new ideas I present .. they require much development, by many people .. then they really for us is profitable ..
Such inspirational posts like yours, Richard causes that describes more about the innovation ..
Here I would like to say that the majority of pilots for emergency landing was going to make sure you water, if she was sure that the plane did not sink .. The waters, even on land is not much, for example, a lake or river. This launch is a big advantage. There is minimal risk of fire aircraft .. The most spectacular example is the "Miracle on the Hudson"
Here you can see how little is needed to plane could swim ..

The plane actually has a tower of different things. plumbing, electrical .. But still has Most sending of empty unused space. . Of course you have to think 10 times, where we can insert each of 1 decimeter foam. Part needs to be done easily removable, in plastic bags or specially shaped profiles, that can be had for service to remove and after the back insert. It's a plane, one of the most complicated machines .. in addition with the high standards of reliability .. so it will not be pumping air into the inner tube ..
