    It's most definitely not cheap ($3,500 + a few thousand for a AC-DC inverter and some solar panels), but the implications for this technology are huge. I could see a smaller, cheaper version of this filling the gaps in developing countries' power grids and bringing electricity to those who can't get it (or can't get it reliably) in a few years' time.

      It's interesting, because it will easily pay for itself in the medium term. It's not cheap in the short-term, but in the medium to long term it's a good deal. And that's normally what the housing market is built on.

      However, it's technology, so in the medium term it will no doubt get cheaper and more powerful. That $3500 battery you buy today will in two years probably be $2000 with twice the capacity. And so on. Do you invest more and upgrade for more returns later on or just stick with version one...
