This Solar-Powered, 'Low Tech' Website Goes Offline When It's Cloudy (vice.com)
An anonymous reader shares a report: Every website and product connected to the internet would not be able to exist without a vast network of wireless routers, fiber optic cables running underground and underwater, and data centers that house the servers which bring the internet to life. Data centers in the U.S. alone eat up 70 billion kilowatts of energy per year, according to a 2016 estimate from the Department of Energy -- that's 1.8 percent of all energy use across the country.
The internet is not ethereal, and a new project from the blog Low-Tech Magazine aims to make that issue more tangible. Low-Tech Magazine -- a blog operated by Kris De Decker that has run on Wordpress since 2007 -- launched a "Low-Tech," solar version of the site that's designed from the ground-up to use as little energy as possible. (Check out the solar version of the site here.) In a Skype call with Motherboard, De Decker said that he doesn't think people don't care about how much energy it takes they use the internet, they just don't understand the extent of the problem. "There's this idea that the internet is immaterial, it's somewhere floating in clouds," he said. "Of course, it's a very material thing that uses resources, materials, energy -- and quite a lot actually." -

Electric Velomobiles: Urban Transportation For the Future, Available Now
An anonymous reader writes with this excerpt from Low-Tech Magazine: "Both the velomobile and the electric bicycle increase the limited range of the cyclist — the former optimises aerodynamics and ergonomics, while the latter assists muscle power with an electric motor fuelled by a battery. The electric velomobile combines both approaches, and so maximises the range of the cyclist — so much so that it is able to replace most, if not all, automobile trips. A quarter of the existent wind turbines in the U.S. would suffice to power as many electric velomobiles as there are Americans." One thing I wish was included in the article — worth reading for the photos alone! — is a chart with prices and worldwide availability for more of the vehicles mentioned. They do mention, though, that the eWAW ("the Ferrari of the velomobiles") costs 7790 Euro. -
Ski Lifts Can Could Help Get Cargo Traffic Off the Road
An anonymous reader writes with this except from a beautifully illustrated, thought-provoking article: "These days, we use them almost exclusively to transport skiers and snowboarders up snow slopes, but before the 1940s, aerial ropeways were a common means of cargo transport, not only in mountainous regions but also on flat terrain. An electrically powered aerial ropeway is one of the cheapest and most efficient means of transportation available. Some generate excess energy that can be used to power nearby factories or data centers. An innovative system called RopeCon (not to be confused with a role-playing convention held annually in Finland) can move up to 10,000 tonnes of freight per hour." -
12 Small Windmills Put To the Test In Holland
tuna writes "A real-world test by the Dutch province of Zeeland (a very windy place) demonstrates that small windmills are a fundamentally flawed technology (PDF of tests results in Dutch, English summary). Twelve much-hyped micro wind turbines were placed in a row on an open plain. Their energy yield was measured over a period of one year (April 1, 2008 — March 31, 2009), the average wind velocity during these 12 months was 3.8 meters per second, slightly higher than average. Three windmills broke. The others recorded ridiculously low yields, in spite of the optimal conditions. It would take up to 141 small windmills to power an average American household entirely using wind energy, for a total cost of 780,000 dollars. The test results show clearly that energy return is closely tied to rotor diameter, and that the design of the windmill hardly matters." -
Computer-Controlled Cargo Sailing Vessels Go Slow, Frugal
An anonymous reader writes "Big container ships are taking it very slow these days, cruising at 10 knots instead of their usual 26 knots, to save fuel. This is actually slower than sailing freighters traveled a hundred years ago. The 1902 German Preussen, the largest sailing ship ever built, traveled between Hamburg (Germany) and Iquique (Chile): the best average speed over a one way trip was 13.7 knots. Sailing boats need a large and costly crew, but they can also be controlled by computers. Automated sail handling was introduced already one century ago. In 2006 it was taken to the extreme by the Maltese Falcon, which can be operated by one man at the touch of a button. We have computer-controlled windmills, why not computer-controlled sailing cargo vessels?" -
Underground Freight Networks
morphovar writes "The German Ruhr University of Bochum is conducting experiments with a large-scale model for an automated subterranean transport system. It would use unmanned electric vehicles on rails that travel in a network through pipelines with a diameter of 1.6 meters, up to distances of 150 kilometers. Sending cargo goods through underground pipelines is anything but new — see this scan of a 1929 magazine article about Chicago's underground freight tunnel network (more details). Translating this concept to the 21st century would be something like introducing email for things: you could order something on the Internet and pick it up through a trapdoor in your cellar the next morning." -
Email In the 18th Century
morphovar forwards a writeup in Low-tech Magazine recounting an almost-forgotten predecessor to email and packet-switched messaging: the optical telegraph. The article maps out some of the European networks but provides no details of those built in North America in the early 1800s. Man-in-the-middle attacks were dead easy. "More than 200 years ago it was already possible to send messages throughout Europe and America at the speed of an airplane — wireless and without need for electricity. The optical telegraph network consisted of a chain of towers ... placed 5 to 20 kilometers apart from each other. Every tower had a telegrapher, looking through a telescope at the previous tower in the chain. If the semaphore on that tower was put into a certain position, the telegrapher copied that symbol on his own tower. A message could be transmitted from Amsterdam to Venice in one hour's time. A few years before, a messenger on a horse would have needed at least a month's time to do the same."
