6:30 pm — 7:30 pm on Friday 04 July 2014 at The Royal Society, London, but turn up at 6.15 pm as this is bound to be a full house for a world renowned climatologist and terrific speaker. Guaranteed to … Continue reading
“Environment Research Letters” has just published an intriguing assessment of the harm which high-flying aircraft inflict on the earth’s heat budget – and how a simple rerouting of long distance aircraft, laterally or vertically, could preclude this effect almost entirely. … Continue reading
Here is a really interesting update – thanks to the BBC – on a question which has worried climate science for a long time – does the exhaust gas of high-flying aircraft make global warming worse? It is not only … Continue reading
Would batteries still have a place in this brave new hydrogen world? And what about fuel cells? We always see in the media the yoking together of hydrogen and fuel cells – is there a reason for this?
As for batteries, yes, we will always need them in some form or another, but only on a comparatively small scale – they simply don’t “scale up” to the capacity which our society needs for town supply or for … Continue reading
Good and necessary question! Certainly, hydrogen will never be able to compete with the way natural gas is stored in nature, dumbly waiting for human technology to access it. However, the supply of water is not in doubt, so … Continue reading
It will not be cheap! But neither are our present fuel bills – and we must not forget that we are preventing enormous future expense for those coming after us, if we cut right down on the planet-heating emissions … Continue reading
Easily, and safely! – but only if it is introduced in a measured way, with public education, and the preparation of all the devices and machines which we are used to. We could take as an example the replacement … Continue reading
