"H2R" is the title of a project developed by Danish-Icelandic artist Olafur Eliasson. What's it all about? This is BMW's 16th art car in which the outer shell is replaced by ice. The H2R is a racing car powered by hydrogen, and it was developed to achieve speed records in terms of "sustainable mobility" (their words). Olafur Eliasson has removed the outer covering of the H2R prototype and replaced it with a complex skin of two reflecting layers of superimposed metal spanning the body of the car.
