Speed Limits And De-restricted Signs Don’t Add Up

All public roads in Britain have a legal speed limit. What then are so-called ‘de-restricted’ speed signs about?   I spend many hours every year on motorways and travelling between various towns (especially at Christmas: no trains – safest and greenest way to travel – so we have little choice but the car).   But must road experience be confusing as well as so un-eco?  Is it time to change the way vehicle speed controls operate?  And maybe also time to challenge current road culture?  More RoSPA, less Jeremy Clarkson perhaps?

Green (Solar) Energy To Resolve Greek Debt?

Could the sun resolve Greek (and Spanish) problems with national debt? Some three years ago now Dreaming Realist lamented the inability or unwillingness to capture the power of Greece’s annual 2,000 hours of sunshine. Perhaps the current European economic crisis means the time is now right to revisit this omission. The Greek deficit is alarming. Carbon (sunshine) now has formal monetary value.

Discussion of these recommendations has produced some interesting ideas about what might constitute almost zero carbon food, even zero carbon meat. Hill grazing sheep, jellied eels and lobster aquaculture are amongst the food items and techniques proposed.

Hot Water Bills In The Land Of 2000 Hours’ Sunshine

Energy is a commodity with variable value, it seems, depending on where you are. ‘We Greeks,’ said a fellow-traveller on the train as we departed Athens, ‘could have free hot water and free lighting all year; but we prefer to pay… Why put an annual 2000 hours of sunshine to good use, when we can produce energy more expensively in other ways?‘ He was, of course, being ironic.
