How long before fuel becomes 'unaffordable'

[TheGuru]

SNP folks its the only way to go, once we get ourselves sorted out we can help you guys out.
Can any of you mind the old Tomorrows World on the BBC, There was this old guy on who had invented some type of new Internal combustion engine, It was a 3 Litre but the size of 2 shoeboxes that used very little juice, never heard a thing since it was probably bought by the big oil companys or maybe even the goverment and shelved until they have fleeced us all.
Incidentally if any of you guys are storing fuel remember and treat it for diesel bug, we get a big problem with this at work on all the emergency generator tanks, because of the percentage of Bio fuel in the diesel it allows a little micro organisim to live in the fuel and it eventually bungs up filters and pumps and stuff ye ken.
