I don't understand why you say experiment... It's a proven technology, clean, safe and with over 1 million wells frac'd in the US it's not exactly new. We've frac'd wells onshore and offshore in the UK, until it became another cause celebre of the green movement, then it became 'dangerous'.
Inject some water, increase the pressure until the fracture pressure of the aqifer is exceeded, fill the resultant fractures with sand to prop them open and a little biocide to protect the groundwater in case of migration. Drop the pressure, recover the water and dispose of safely and then let the gas flow to surface.
It's very simple, and safe.
Please, please don't believe the propaganda!

It's the protection of the ground water that worries me the most. In the US they don't need to disclose the chemicals they pump into the ground during the process. Some law about trade secrets. Ground water is a precious resource that should be protected. LA's huge reserve was well and truly polluted by industry in the last century and now with our drought, is unusable to a great extent. Fracking is of huge economic benefit and the US has done well to lessen dependence on dodgy parts of the world. Seems there is some connection to small earthquakes also.

I beg to disagree about the kids. I think the young generation are more aware of the grim state of the planet than any before. Sadly politics tends to be run by old people.

Must admit, there have been times in my life where I've mad bad decisions, and ended up in some bad places.
Thing about bad places is that they have limited resources. The fortnightly giro filled my cupboards and fridge for a week, and I'd be able to buy 50g of golden virginia and a box of rizlas. But that's only if I budgeted properly, and I really didn't a lot of the time.
So the roll ups would be smoked, and I'd run out of money. The liebig's minimum in this case was tobacco. I had plenty of papers and ways of combusting, even if it meant using the hob of the cooker. But after rolling a skinny one from the dust at the bottom of the pouch, I had no means of obtaining more, without subbing from my parents or selling something to cash converters.
So I would never empty the ashtray. This, towards the end of the fortnight was a useful resource.
The tobacco I pulled from my dog ends was not as nice as the stuff from the pouch, but it was tolerable. 50g of tobacco from the pouch though, would only yield perhaps 15g of dog end tobacco.
If 50g lasted me 10 days, 15g would last for 3. Sometimes though, for whatever reason, I'd be raiding the ashtray after a week. Two or three days later, and that resource was drained, and I'd be using third hand tobacco.
Now that was getting seriously vile. Not far from par with picking up butts from the floor of the local bus station. I've done that too.
Beyond that? 4th generation tobacco was really not worth smoking.
Given a choice, I'd pick the tobacco from the pouch every time. The only time I'd start pulling apart butts from my ashtray is when the pouch stuff had gone.
What shall we do when the light sweet crude has gone? Well frack for it, and drill the deep oceans and arctic wildernesses.
When's the next giro due?
