Giving Up Alternating Current

An anonymous reader writes: Yesterday we discussed Soylent, the artificial food substitute created by Rob Rhinehart and his team. As it turns out, this isn't Rhinehart's only unusual sustainability project. In a new post, he explains how he gave up on alternating current - a tough proposition for anyone living in the U.S. and still interested in using all sorts of modern technology. Rhinehart says, "Most power in the US is generated by burning coal, immediately squandering 67% of its energy, then run through a steam turbine, losing another 50%, then sent across transmission lines, losing another 5%, then to charge a DC device like a cell phone another 50% is lost in conversion. This means for 100 watts of coal or oil burned my phone gets a mere 16." The biggest hindrance was the kitchen. As you might expect for the creator of Soylent, he doesn't cook, and was able to get rid of almost all kitchen appliances because of that. He uses a butane stove for hot beverages. He powers a small computer off batteries, which get their energy from solar panels. For intensive tasks, he remotes to more powerful machines. He re-wired his apartment's LED lighting to run off direct current. Have any of you made similar changes? How much of an effect does this really have?

Epson Is Trying To Kill the Printer Ink Cartridge

An anonymous reader writes: Inkjet printer cartridges have been the bane of many small businesses and home offices for decades. It's interesting, then, that Epson is trying something new: next month, they're launching a new line of printers that come with small tanks of ink, instead of cartridges. The tanks will be refilled using bottles of ink. They're reversing the economics, here: the printer itself will be more expensive, but the refills will be much cheaper. Early reports claim you'll be spending a tenth as much on ink as you were before, but we'll see how that shakes out. The Bloomberg article makes a good point: it's never been easier to not print things. The printer industry needs to innovate if it wants us to keep churning out printed documents, and this may be the first big step.

FAA Has Approved More Than 1,000 Drone Exemptions

coondoggie writes: The Federal Aviation Administration today said it has issued 1,008 exemptions to businesses wanting to fly unmanned aircraft in the national airspace. Such small drones have been on the bad side of the news in the past few days: there have been at least three complaints about the diminutive aircraft flying near the flight path of JFK airport in New York. All three of the flights landed safely but the events prompted New York Senator Charles Schumer to call for "tougher FAA rules on drones," as well as geofencing software that could prohibit a done from flying higher than 500 feet, and keep it two miles away from any airport or sensitive area.

Municipalities open their GIS systems to citizens

Many public administrations already use open source Geographic Information Systems (GIS) to let citizens look at public geographic data trough dedicated Web sites. Others use the same software to partially open the data gathering process: they let citizens directly add geographic information to the official, high-quality GIS databases by drawing or clicking on digital maps.
