Maybe, but just by culling the top 5% of the polluters, thats 25% of the pollution cured, this will reduce the need for expansion in china, so improving survival rate. In the short term anyway......... Yeah, AG has been soft peddling, damn commie republican Martin

The 'plug-in' hybrid hugely improves efficiency when it can run on battery power alone as is often the case.

Conserving it (mainly not squandering it with huge V8 SUVs and the like) would help cheap oil last longer though. Graham |
