Nuclear fusion is different because it is when both are put together. It is much more controlled, less difficult and poses fewer dangers once used. I am not suggesting that we should go into that but we need a discussion on it, if only to rule it out. It could form part of the discussion that the Minister, Deputy Eamon Ryan, suggested we might have.

In the last month, BMW has put 200 hydrogen-powered cars on the market. This is basic science as opposed to nuclear science. Water, designated as H2O, comprises two molecules of hydrogen to one of oxygen. The separation of hydrogen from water produces the cleanest source of energy on the planet, and when used the waste is clean water. It represents the future and while it is possible to do it now it cannot yet be done efficiently. In other words, it takes almost as much energy to extract hydrogen from H2O as the energy the hydrogen would produce afterwards. In real terms, therefore, the game is not yet worth the candle but it will develop as a future energy source. We should be examining that possibility now.

We need more rail lines and park and ride facilities. There is empty space where the M1 and M2 meet the M50, so it would not be difficult to locate acres of parking space there, building underground if necessary. I do not know why it is not being done. If I were Secretary General of the Department of the Environment, Heritage and Local Government I would take such a decision within two weeks. I see no reason why it cannot be done. We have been talking about it for ten years whenever we discuss building standards, yet nothing has happened.

The capturing of methane from landfills also needs to be undertaken. While the building regulations are welcome, triple glazing should be encouraged by grants. All new houses should have an alternative energy source. I telephoned two local authorities recently to ask if they would give any preferential treatment in terms of seeking planning permission for a proposal to build a totally eco-friendly house. The answer was "No" and as far as I know nobody does it. We have had long debates about one-off housing but if somebody proposes to construct something that clearly does not damage the environment, is self sufficient and uses its own energy, we should encourage it.

Any community in any part of Ireland which puts its hands up and offers to take full control and responsibility for all its waste and energy requirements should be given a tax break. That can and should be done because it is not that difficult.
