When you think about it, it may not be a bad idea, glow in the dark trees replacing street lights and saving energy. Dutch designer Daan Roosegaarde thinks what we learn from nature could help develop innovative ideas.

His idea is bioluminescent planets that don’t run on batteries or solar power but comes from splicing DNA of fireflies and jelly fish that already glow. You put the DNA in the plant and it emits a soft glow, the glow would have less of a glow than a street light, but on streets where there are a lot of trees and planets, it could light-up nicely.

According to Roosegaarde it would be environmentally friendly and would save energy, is it practical? That is yet to be seen!
