Planet of the Apes (1969) — If you’re a space-faring, time-traveling astronaut who crashes on a strange planet, it behooves you to bring a firearm with you in the survival kit — especially if you’re likely to run into a bunch of highly evolved, human-hating apes. I’ll leave it to the experts as to whether a Colt Model 1903 Pocket Hammerless is the best gun for the job.

Clear material on windows harvests solar energy - A new type of “transparent” solar concentrator can be used on windows or mobile devices to harvest solar energy without obscuring the view. Past efforts to create similar materials have been disappointing, with inefficient energy production or highly colored materials. “No one wants to sit behind colored glass,” says Richard Lunt, an assistant professor of chemical engineering and materials science at Michigan State University. “It makes for a very colorful environment, like working in a disco. We take an approach where we actually make the luminescent active layer itself transparent.” The solar harvesting system uses small organic molecules developed by Lunt and his team to absorb specific nonvisible wavelengths of sunlight. “We can tune these materials to pick up just the ultraviolet and the near infrared wavelengths that then ‘glow’ at another wavelength in the infrared,” he says. The “glowing” infrared light is guided to the edge of the plastic, where it is converted to electricity by thin strips of photovoltaic solar cells. “Because the materials do not absorb or emit light in the visible spectrum, they look exceptionally transparent to the human eye,” Lunt says.
