Make blog posts about an art installation that uses over a thousand fluorescent bulbs that are powered from the ambient energy surrounding power lines.
It’s a pretty incredible sight.
On a more practical level, though, I’ve not seen a better visualisation of energy waste from centralised power generation (that is, mammoth power stations in far-away places shipping energy to cities). And no better case for shifting to a more decentralised, renewable energy future (i.e. solar panels and mini-wind generators on roof-tops etc.)
