Pulp-based computing

Computer chip embedded in paper In computers, we have software and hardware. Jokingly, the human brain is sometimes called wetware. Up next: pulpware!

OK, technically it’s hardware–wires, sensors and computer chips–embedded in paper or cardboard. A spiral of conductive ink can be a speaker, or a touch sensor. Two layers, and a page can tell when it is being bent. Among the possible creations are books that talk or light up when their pages are turned (personally, I can’t think of anything more annoying!), or boxes that can tell you how much their content weighs. (Maybe with voice messages. "Don’t even try it, buddy! I’m a hernia-in-waiting!")

The project was outlined at the recent International Conference on Ubiquitous Computing in Innsbruck, Austria. Here’s a video of the production process and some applications. Here’s the original paper. And here’s the research project’s website.

Dirty water in, clean water out

Lifesaver water purification bottle The Lifesaver is a water bottle–but not just any water bottle. Through "an advanced ultra-filtration membrane that incorporates a high specification carbon block" it can convert dirty water to clean in a matter of seconds–you put in the water, pump it through the filter a few times, then drink. The cartridge is supposed to be able to filter out waterborne pathogens and eliminate bad tastes and odors, too. The replaceable cartridge has a filtering capacity of 4,000 to 6,000 litres, so it’s not short-lived: 700 litres is a year’s supply of water for one person. The military is interested, naturally, but an even more important application would be to supply clean drinking water after disasters such as the Boxing Day tsunami in 2004 or Hurricane Katrina: instead of distributing bottled water, you could distribute bottles that clean the water that’s at hand. And even in the absence of disasters, access to clean water is a worldwide problem.

Hmmm. My daughter’s water bottle is starting to smell funny. Maybe I should be getting her one of these…

Or maybe the Lifestraw is the way to go. It’s a plastic pipe filter 25 centimetres long and 29 millimetres in diameter that costs just a few dollars and can purify up to 700 litres of water.

A word of advice, though: when giving a Lifestraw to a suffering disaster victim, find a different way to instruct him in its use than telling him to "suck it up."

Fixing the future – Karl Schroeder on technological solutions for climate change

Design concept for a 'vertical farm'Many of the commonly tabled options for dealing with the incipient ecological crisis our planet is facing involve turning our backs on technology. One of the people taking the opposite position – namely that sustainability isn’t a zero-sum game – is Canadian science fiction author and foresight consultant Karl Schroeder, who talks about the potential of technologies like fusion power and vertical farming to avert catastrophe without destroying the potential of the human species in an interview at EcoGeek.

And sometimes you just need to look at the bright side of things – for example, the rising cost of gasoline might reduce the incidence of obesity. It all ultimately boils down to personal lifestyle choices, though, at least as much as technology – so maybe we should think seriously about having less children.

Eye-tracking tech to replace mouse within five years

eyeball close-upAs someone who started using computers back in the good old days when you had to bash every instruction into the keyboard at the command prompt, I still feel kind of grateful for the revolutionary interface change that the now-standard mouse brought with it. But after a few hours trawling the web, my right hand starts telling me that there has to be a better way. And there is, thanks to a bunch of boffins from Stanford University who’ve developed a system that allows you to replicate the functions of a mouse interface using a few keyboard hotkeys and the motion of your eyeballs.

What a great cover-up for hangovers in the workplace that will be – “Your eyes are bloodshot – heavy night out?” “Nah, stayed at home and read a Doctorow novel.” [Image by babygoldfish]
