Me thinks the solar tumble dryer is good idea.

I've been wondering about the solar tumble dryer and perhaps it would have a bigger effect than I thought.

If only Americans would hang their laundry out to dry – and commit 16 other acts of environmental kindness – they could slash US carbon dioxide emissions by 7.4 per cent by 2019.

"This study is the best estimate we have to date of how effectively behavioural change could cut US greenhouse gas emissions," says Ruth Rettie, who leadsProject Charm, a group based at Kingston University in London that investigates ways in which people's behaviour could be influenced.

"Everyday household practices – for example tumble drying or using air conditioning – are resistant to change because they are embedded in conceptions of comfort and convenience," says Rettie. "But with the right combination of policy tools and social marketing, interventions can result in major behaviour changes."
