Electric car charger
It's a new business but one that could develop as electric vehicles take to the streets--Aerovironment is one of a handful of companies that are making electric car charging stations for households. Cars such as the Chevy Volt and Nissan Leaf can be charged with existing household outlets. But upgrading to a higher-voltage charging station, which need to be installed by an electrician, will cut charging time roughly in half.
