Use the energy from the nuclear power stations
That's the nice thing about using H2/O2 as a fuel, you start with water, reduce (I'm using the chemical term reduce here) the hydrogen using electrolysis storing the oxygen too, then you oxidise the hydrogen out of the bottom of the rocket and get loads of water again.

Well if we don't go for space, we can always send it to the sea bed, it's not like it's going to float to the surface!
The cost of decomissioning is apparently less than 5% of the total electricity generation costs according to the Wold Nuclear Association.

I agree we need to stop messing up the planet, but such changes *HAVE* to come from the top down. There's no point in you or I saving a little here or there if other governments and industries are doing their damndest to ignore the problem entirely. |
Definitely agree.
The politicians can't spend anymore time faffing about undecided.
They need to actually do something.
Show people how safe the new nuclear power stations are.
The problem is, nuclear scares people, they don't understand that waste from a nuclear powerstation can be dealt with more safely than a fossil burning powerstation, where the waste flows out into the atmosphere and causes global warming along with acid rain.
Both produce nasty pollution, but at least with nuclear we can keep it contained and if some does leak the global environmental impact is much smaller than CO2 etc.
If possible convert any oil or coal burning power stations to gas (don't know if it can be done), it will help a little until they're no longer needed.
Encourage people to use low energy light bulbs. Did you know that a 2p increase in fuel does less for the environment than making everyone use at least one low energy light bulb, but costs the public so much more?
