IREM ignites the Imagine Peace Tower by Yoko Ono
It was in 1965 that the artist Yoko Ono developed her concept of a LIGHT HOUSE and just two years later she was asked by John Lennon to build one for him in his garden; this was impossible though, as at the time the Light House was purely conceptual! It would take little more than 40 years until Yoko Ono converted the once conceptual Light House into the very physical experience of the ...

Steam from the sun - New spongelike structure converts solar energy into steam
Original story at MIT News The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is ...
