RE: NATURE INSPIRED INVENTIONS --- Photovoltaic cells; the reason for the non-reflecting eyes of the moth.
As a citizen of a Mediterranean island country that has sunlight year-round, I often wonder why every single house's roof isn't lined with photovoltaic cells. I haven't been able to come up with an answer, except for stupidity and short-term thinking (the government waited for water to get completely exhausted before deciding to build desalination plants, for instance...).
Probably, they felt using hydropower for electricity generation would be quite cheaper for them. But am sure with this recent advancement in photovoltaic cells, they will surely have a rethink. Thanks for stopping by @alexander.alexis
