Well as Earth Hour approaches and we realise we need a green and non-electric light source, we could do worse than turn to tree power using a traditional Greco-Roman technology...
These handy lamps cost about 2.3p so we can make lots and construct a green and eco-friendly light installation to celebrate #EarthHour2019 (this Saturday) and commemorate our shared European Civilisation whilst we can :)
Meet as usual at the hut.
