Les VÉ récupère de l'énergie au freinage, mais pourquoi ne pas en récupérer en roulant??? Une petite éolienne placé en dessous de l'auto couplé à un dynamo et voici une source faible mais quand même présente d'éolien en roulant!

Il existe plusieurs façon de prendre l'énergie de la nature, l'eau, le vent ou le soleil. Mais chacune d'elle comporte des inconvénients et/ou des périodes moins rentables. Par exemple, l'energie solaire ne fonctionne pas la nuit, l'éolien ne donne rien sans vents.. Une seule source d'énergie ne manquera jamais et est toujours stable, la gravité. Regardez un exemple de comment la gravité pourrait nous fournir de l'énergie durable, constant et sans fin : http://www.theguardian.com/artanddesign/architecture-design-blog/2012/dec/14/gravity-light-sand-powered-lamp

There are some cities that have a community garden and based on that I think there should be a community compost. Some people are unable to have their own or there is no pick up of that type of thing but they want to take part in doing it.

Many people are getting sensitive to the chemicals in our cleaning products.And as the chemicals from the dryers are vented outside,it would be better if people would use healthy alternatives like balls.
