Back in June I posted about American Express' "Members Project," a contest where cardmembers submit project ideas on how to make the world better. For every cardmember that registers at the site (either with a project or just to vote), AmEx will donate $1 towards the winning idea, up to a max of $5 million dollars. So, if 4 million people register, the project gets $4 million.
The top 5 projects were recently announced and one is in the renewable energy category. The project idea is to create a small solar power unit that would be simple and small enough to use in any home. Read the full description or vote here.
The winner will be announced August 7.
