Buying a light bulb used to be a no-brainer. Now it's a brain teaser; the transition to more energy-efficient lighting means choosing from a dazzling array of products.

We've long identified bulbs by their wattage, but that is actually a measure of electricity, not the brightness of a bulb. The amount of light a bulb generates is measured in lumens.

Just last week I was lamenting a severe lack of comedy-based video games, where perhaps getting a hearty laugh is the goal rather than quelling a rebellion or fighting off hordes of zombies.

Inside one in a series of abandoned homes along a blighted block of Detroit's Brightmoor neighborhood, filmmaker Tom McPhee walks through the remnants of a life — broken furniture, scattered knickknacks and a flooded basement.

"This is fresh water that's coming into the basement here," McPhee points out. "All of that plumbing has been ripped away 'cause someone found a value in it, so they don't care that it's running. This is all over the city."

I hit the streets of San Francisco to ask strangers their favorite search terms for online pornography. It was not hard to get answers, even on the record.

"Teacher porn, student-teacher fantasy," Jason Ravel says at a coffee shop. "That's who I was around most often in grade school. I was a really good student."

Chanelle Dorton, who's passing by a train station, is into ebony lesbian sex. "I don't like straight porn," she says.

Cab driver Neel Bell likes "heterosexual porn that doesn't involve porn stars. It lets you think that it's a real-life situation more."

If you can barely swing a hammer, you can still build your own home.

Builders at the Maker Faire in New York City proved this point last fall, with something akin to an old-fashioned barn-raising.

The event celebrates the do-it-yourself aesthetic, particularly when it comes to digital fabrication and open-source construction plans. Using wooden mallets cut from plywood, a crew of eight banged together the slotted frame of a WikiHouse without a single nail.

The result: a livable home.

AUDIE CORNISH, HOST:

From NPR News, this is ALL THINGS CONSIDERED. I'm Audie Cornish.

And now to All Tech Considered.

(SOUNDBITE OF THEME MUSIC)

CORNISH: Today is a tricky business of keeping some American technologies out of foreign hands. When a man from Hong Kong met with an aerospace company in Seattle last week, he was really dealing with an undercover Homeland Security agent. See Kee Chin allegedly tried to buy $85,000 worth of highly specialized accelerometers. He was arrested and charged with trying to smuggle the parts to China.
