Energy storage
Mass production of the DIY home electricity system could be highly beneficial. It could perhaps be facilitated trough a link-up with existing car manufacturers (see http://docs.google.com/View?id=dcwtr665_286fb6wwbfq and http://docs.google.com/View?id=dcwtr665_2794fsjsgp4)

Other projects that facilitate a move to a sustainable society would also be cost-effective. See
