The capacity of our digital storage devices has skyrocketed in recent years. But there’s one storage medium that still kicks the crap out of our state-of-the-art solid state, and humans didn’t invent it. It’s called DNA. Read more…

A Century-Old Device May Be the Future of Electronics

There’s a new device in the works over at DARPA, the agency known for pushing the technological envelope with mind-controlled prosthetics and drone-launching submarines . This latest innovation? The vacuum tube. You might remember it from the first time humans invented it, way back in 1904. Read more…

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? Read more of this story at Slashdot.

Soylent 2.0 Comes Bottled and Ready To Drink

An anonymous reader writes: Soylent has announced today their latest product, Soylent 2.0. It comes premixed and ready to drink in recyclable bottles. Each bottle is one fifth of a scientifically balanced daily meal plan, will last up to a year unrefrigerated, and will cost you $2.42. A Soylent blog post reads in part: “Not only are its ingredients vegan, Soylent 2.0 reaches an unprecedented level of environmental sustainability with half of its fat energy coming from farm-free, algae sources. This next generation agricultural technology has the potential to reduce the ecological impact of food production by orders of magnitude, signifying a major step towards a future of abundance, a world where optimal nutrition is the new normal.” Read more of this story at Slashdot.

Berlin Spends $16 Million a Month To Maintain This Never-Opened Airport

As the EU’s self-appointed morality police, Germany publicly spanked Greece earlier this month for being so financially frivolous. Well, Germany has its own money troubles! Namely, a catastrophe-riddled $6 billion airport that the country continues to pour money into—with no opening date in sight. Scheiße! Read more…

Why Airplane Flights Are Taking Slightly Longer Every Year

In the future, hopping on a plane from LA to Honolulu might take a minute longer than it does today. You probably won’t miss that lost moment, but the airline industry will: The tiny additional flight time could amount to thousands of extra hours and millions of dollars of additional jet fuel each year.

What Are All Those Weird Noises You Hear on an Airplane?

I used to work at Boeing and repaired the computerized part of the machines which put together 747’s. People not familiar with airplanes are scared because they are forced to be quiet and go along with acting normal while stuck in a tube hurtling through the air at 600 miles an hour, and 30, 000 feet above the earth. What could go wrong? Read more…

G7 Vows To Phase Out Fossil Fuels By 2100

Taco Cowboy writes: The G7 group of countries has issued a pledge that they will phase out fossil fuels by the end of this century. The announcement was warmly welcomed by environmental groups. “Angela Merkel took the G7 by the scruff of the neck, ” said Ruth Davis a political advisor to Greenpeace and a senior associate at E3G. “Politically, the most important shift is that chancellor Merkel is back on climate change. This was not an easy negotiation. She did not have to put climate change on the agenda here. But she did, ” Davis said. The G7 plege includes a goal proposed by the EU to cut emissions 60% on 2010 levels by 2050, with full decarbonisation by 2100. Read more of this story at Slashdot.
