Mama always told you not to stare into the sun. She might have added lasers to the list of no-nos — looking directly at the concentrated beams can burn your retinas. So who’d have thought they’d make an ideal light source for televisions? Mitsubishi’s 65-inch LaserVue taps this tech to produce an astonishingly vivid picture. The rear-projection set’s color range is twice as broad as a typical HDTV’s, yet it consumes 33 percent less energy than a similar-size LCD. Though this 3-D-ready TV may seem straight outta Solaris, you don’t need to fear its newness; unlike most nascent technologies, lasers have stamina. The company claims they’ll never need replacing. So go ahead and screen those Lost DVDs 24/7. Or if you’re feeling reckless, fire up your Blu-ray player to savor Angelina in all her Beowulfian glory. Kind of like staring at the naked sun, only hotter.
