Electric Handmade Car

Another of Life's wonderful ironies is that I was once offered a retail subsidy of ~$4,000 to install PVs (photovoltaic cells) on my roof BUT there is no equivalent subsidy for taking a petrol-guzzler off the road - which reduces air pollution and stops consuming hard-to-replace oil. 

The PV subsidy was an attempt to distort 'normal' macro-economic behaviour, and it worked. Clearly too well, as it has largely been dismantled here in Perth, Australia. The effort we put into 'getting the settings right' when we want to effect long term change can be remarkably effective.
