Roughly 6 billion more years. Then the sun will expand and eat the earth.
There is no telling we give it an estimate of twenty years.
timber is expected to last at list 15-25 years.
As long as there are waves. Probably a few hundred million years - after that, at some moment the oceans are expected to evaporate as the Sun gets hotter.
it will not degrade and will last for long
A few minutes
it goes on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on. That's about it.
The UK has been nuclear for a very long time. It has lots of nuclear energy stations and lots of nuclear weapons.
Since most of the energy we get from the Sun is the result of nuclear fusion, I guess that would mean that we would receive ALMOST NO energy from the Sun. We WOULD receive some energy as a result of the Sun contracting due to gravity, but that wouldn't last long.
The energy of the nuclear fission is transformed in heat or electricity.The use of nuclear fuels is profitable on long term.
another 5 years
40 to 50 years
So long as there is a supply of fuel, yes.
