On seeing this, my thought was that perhaps one day in the future solar power could be used to maintain indoor houseplants. Aside from our reactionary horticultural education system, light is the limiting factor for the use of plants in buildings.
What if we could position a small solar collector like this in a sunlit location? It could then power lights for our indoor plants. Solar power and highly efficient LED lighting could one day propel a great leap forward in the use of urban greenscaping and urban agriculture.
Let's all hope that we find the forward looking leadership to make it happen.
