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.
The latest edition of the Civil Service Quarterly from Her Majesty's Government accidentally included a satirical poster from Scarfolk, the nightmarish alternate reality of a perpetually renewed decade of Thatcher/Cthulhu crossovers.
Back when I was a teen Car Wars player, one of my great pleasures was kit-bashing toy cars together with arms and armor from tank models to make Mad Max-ish battlewagons to use in our autoduels (a friend with family in the USA used to help us blow up our cars with smuggled in firecrackers […]

It’s good to be proactive, but when it comes to preparing for an emergency situation, one of the most important items you can pack is a flashlight. After all, whatever else you include in your kit won’t be of much use if you can’t see what you’re doing. The Viper 1000-Lumen Tactical Flashlights not only […]
Chances are you took a handful of language classes in high school, and aside from a smattering of conjugations and vocabulary words, the only things you likely remember are the dry, rehearsed sentences that did little to make you speak like a true native. If you’re still hoping to learn a new language but want […]
