Yesterday, I saw a demo of the Homebiogas bioreactor: it's essentially an artificial stomach that uses colonies of microbes to digest your home food waste (it can do poop, too, but people tend to be squeamish about this), providing enough clean-burning biogas to cook your next meal, heat your house, or run a generator -- what's left behind is excellent fertilizer.
Biogas is a pretty well-established technology (Marco Polo came back from China with stories of pipes coming out of subterranean middens that supplied clean-burning gas), but it has fallen out of favor in the past century or so. Bioreactors are small, cheap, odorless, and very simple -- the people behind Homebiogas also build open source bioreactors all over the world, in refugee camps, prisons, cold climates, hot climates, cities and the countryside.
Home bioreactors are small enough for apartment living, and provide a bridge for people trying to live on renewables -- powering generators or supplying cooking gas when the sun is down or the wind stops blowing.
My family and I just bought a house in Southern California and are planning a renewables renovation in the next couple years (depending on book advances!), and in addition to a solar roof, I'm definitely going to look at setting up our house to turn our food-waste into energy.

Daniel Moghimi, Berk Sunar, Thomas Eisenbarth and Nadia Heninger have published TPM-FAIL: TPM meets Timing and Lattice Attacks, their Usenix security paper, which reveals a pair of timing attacks against trusted computing chips ("Trusted Computing Modules" or TPMs), the widely deployed cryptographic co-processors used for a variety of mission-critical secure computing tasks, from verifying software […]

Sous vide cooking: It sounds fancy, but it’s actually one of the easiest and most reliable ways to cook. It’s the reason why many restaurants are able to put out delicious dishes with a consistent flavor. All you need is the right equipment, and that hasn’t always been available to those outside the resto crowd. […]
The more you use your computer, the more it becomes possible for others to use it too. Where there are anti-virus systems, there are hackers looking for a way to get around them. That’s why it’s important to get software that doesn’t just passively scout for viruses in the background. The folks behind GlassWire have […]
Knowledge is power. It’s a cliché, but sometimes things turn into a cliché because they’re true. If you’re making your way through the world of business and entrepreneurship, it only makes sense to read about the insights of people who have climbed that ladder before you. Trouble is, the modern workday doesn’t leave a lot […]
