i think we also need to work on a long life battery system that is relatively harmless to the environment when destroyed.

You know I think the issue is the grid itself and our perception that we need hundreds of volts and amps being pumped in to our homes, really we dont, you can power all your lighting and most household appliances from 12/24 volt's already and the technology to store and generate 12/24 volt's is already with us, you can easily step up the 12/24 volts to 110/230 for the things that need it, homes can be powered as caravans/boats and we could really scrap the grid now for domestic purposes cause 12/24 volt solar panels and wind turbines and leisure batteries just aren't that expensive.
