I thought it might be a good thing to have a topic devoted to this important subject.

Back to the nukes then........

 On the positive side, it will provide jobs and reduce our dependance on imported gas.  The greens are duty bound to poo-poo any new form of energy because it doesn't encourage us to use less of it.  

Its actually exactly the same stuff as the usual natural gas (impure methane) , except it's extracted from places it wasn't practical to extract from when it was cheap.

"Apparently it's worse for the environment than coal and can be extremely hazardous to those living in close proximity." - Calluna

There might be some exaggerated claims about danger because of the old method where they set fire to the shale underground to heat it up and drive out the gas and liquid. Now they use hydraulic pressure and Shell have a method where heaters are placed below ground which warm up the shale over a period of several years. I don't know which method they are using at the Bowland site. The main concerns from the public have been about possible groundwater contamination.

You'd have to read the whole article - I haven't time to precis it here. And yes, it is 'fracking' - my memory recall is not what it used to be!

One of our modern diseases is the illusion at 100% safety is attainable. How many deaths can be attributed to biofuel each year? The funny thing is that the same impossibly high standards aren't used to assess things like motor transport or home DIY. The ironic thing of course is that the safest method of energy production is nuclear. It is also the most expensive. Eventually we will have to bite the bullet.

Link now works. The process of adding links seems to be a bit hit and miss (for me anyway). I think you have to make sure you've given it a title or something.

Thanks for posting the article Cally and I've read it through. They make it sound like the end of the world, typical newspaper reportingof course - although I'm not saying there isn't some truth in it and a need for conceern. As I said above, groundwater may get contaminated. But I always mistrust phrases like "combined with up to 596 rock-dissolving chemicals". The words "up to" are key - they covers anything from 1 to 596 and it implies they are using 100s when all it probably means is there are hundreds of chemicals that *could* possibly be used to achieve the same thing. If I lived in the Bowland area I would be wanting to know more about Cuadrilla and what it was trying to do and how. And most of all I would want to find out what sort of people were in charge - it's the people who worry me more these days than the technology (same for nuclear).

Heather, the reliable way seems to be to copy the address, insert a word like link in the text, highlight it, click on the chain symbol in the box menu and paste the copied address into the appropriate box.  I only learned that this year thanks to a member who put me right. (Wonderful site)

I thought the same thing Tiz. Fear sells newspapers. I suppose the trick is to use your head and pick the bones out of it. One clue is often the fact that no benefits are mentioned. Mind you, I watched two TV progs last night, one on Chernobyl and one of the deep storage facility for nuclear waste being created in Finland. Fascinating stuff, planning a facility with an expected life of 100,000 years minimum. Then coincidentally I watched a C5 prog on supersized grime and one of the jobs was withdrawing spent fuel rods from the redundant reactor at Sizewell.  They played the film of the train crashing into a transport flask to test it, worth it just for that!

Yes, I do that and then click Insert. It looks as though it's been turned into a link when you go back to the post. When it doesn't work, you repeat the process and discover mice in the URL box (or summat about 'mce') where you pasted the URL. 

So you paste in the correct URL again, set the link to open in a new window on top of OG, give it a title and then it seems to work. Gentle curses also seem to chivvy it along.

Have a look at the graph on this web page of the US National Oceanic & Atmospheric Administration showing global monthly mean CO2 level. The red line follows the annual seasonal cycle and the black line shows the trend after correction for the seasonal effect. No sign of it falling yet!

Fascinating Tiz. Not much reason to be cheerful if that graph is correct! Given the source, it's likely to be right.

Interesting stat on Farming Today. Some of the worst hit counties have had below average rainfall for 13 out of the last 16 months. That's getting close to a trend!

Just  been announced on R5 that "fracking" in the Blackpool area has been suspended due to another small earthquake overnight.  Take care you people up there!

David, there was an interesting piece on the World Service about hydraulic fracturing this morning. They mentione the two tiny 'quakes at Blackpool and gave examples of other larger ones in the States. Problem is of course that shale oil and gas is the next big thing. The 'experts' say that Europe could be a net exporter of energy, evidently we have lots of shale!

It's official, The Met Office have collated all the figures and some drought hit counties are the driest they have been for 100 years. Overall, Spring 2011 is the second driest for 100 years for England.

I wasn't familiar with the development of cars powered by compressed air but my father-in-law directed me to this Wikipedia page. The pros and cons of the approach are interesting to read. I would have thought the production of compressed air might have been too energy intensive. Interesting comments also about carbon fibre storage tanks not generating shrapnel if they explode. That's especially relevant for me after having spent a week in Bude, Cornwall, where Sir Goldsworthy Gurney lived, the man who invented the steam-driven car. A flaw in the first design was placing the passengers immediately above the boiler!
