Here is a great little article from the BBC about a Brazilian man coming up with a bright idea:
I read something about the use of those lamps in the Philippines quite a while ago but didn’t know they were invented by a Brazilian. Thanks for sharing the link, Sanne.
But this only works during day time
It seems he is creative to made something new.
Well, I’m 50% brazilian and want to say that I never heard about this man after 20 years living here.
The media is concerned about world cup games and never show things that could change our lifes.
