'Did you hear...'

Dress for success. Techies generally scorn the hot fashion trends set by top designers like Vera Wang or Manolo Blahnik. But they're surprisingly forward-looking when it comes to geek gear. This month's Buzz fashion flash: the new Solar ScotteVest, fitted out with solar panels to power devices in 30 hidden gear pockets; the Gadget Tie, decorated with a tasteful pattern of cell phones, PDAs and MP3 players; and the Momodesign Talk'n'Ride motorcycle helmet, embedded with Bluetooth wireless connectivity. Climb off the bike and settle down in the Verte advanced ergonomic chair, whose dynamic 'spine' adjusts in three dimensions just like human vertebrae.

Lyrical geeks. Almost 600 Beatles fans have voted in the JoyPoll run by www.geekculture.com on their favorite Paul McCartney-parody song titles. Current winner: 'Bandwidth on the Run.' The lame lyrics: 'Stuck inside these four walls, never seeing no one, sounds like T1 heaven.'

Spinach sandwich. Handheld computers and wireless phones have a ravenous appetite for nickel-metal hydride and lithium-ion battery juice, and soon-to-be-announced portable devices will get a charge out of hydrogen or alcohol fuel cells. But who knew batteries could emulate Popeye the Sailor Man? PhysOrg.com this month reported that MIT researchers, bankrolled by the Air Force, Defense Advanced Research Projects Agency and National Science Foundation, have come up with a solid-state power source based on ground-up spinach chloroplasts mixed with detergent. The spinach sets up a teeny-tiny electronic circuit when laser light falls on it. Power, we need power at buzz@postnewsweektech.com.
