Alt-week 9.22.12: Quantum Scotch tape, moving walls and scientific beer

Alt-week peels back the covers on some of the more curious sci-tech stories from the last seven days.

Altweek 92212 Quantum Scotch tape, moving walls and scientific beer

Sometimes, here at alt.engadget.com, we're literally on the bleeding edge of technology. We get to explore concepts and ideas that are almost nebular in nature. Not this week though, where there's a distinct utilitarian aroma in the air. The glittery overcoat of future science is replaced by the rolled-up sleeves of good old-fashioned engineering. A bit of sticky tape, a proof of concept omnidirectional bike and a hardware matrix wall. After all that, you'll probably want a beer to wash it down with. Fortunately for you, it's all here. This is alt-week.

Researchers create record-breaking solar cell, set bar marginally higher

Researchers create record-breaking solar cell, set bar marginally higher

Solar cell development is typically a small numbers game, and a group of researchers at the University of Toronto have managed to eke out a few more percentage points in efficiency with a new record-breaking cell. Setting a high mark for this type of cell, the team's Colloidal Quantum Dot (CQD) film harvests both visible and non-visible light at seven percent efficiency, a 37 percent increase over the previous record. The breakthrough was achieved by leveraging organic and inorganic chemistry to make sure it had fewer nooks and crannies that don't absorb light. With the advantages of relatively speedy and cheap manufacturing, the technology could help lead the way for mass production of solar cells on flexible substrates. In the meantime, check out the source for the scientific lowdown.

Insert Coin: Atlas human-powered helicopter gunning for elusive Sikorsky prize (video)

In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

insert-coin-atlas-human-powered-helicopter

The AeroVelo group, a team of students and professional engineers, wants its Atlas helicopter to hover for one minute, reaching at least three meters (10 feet) powered by human muscle alone. If the grunt-powered machine succeeds, it'll nab the American Helicopter Society International's $250,000 Sikorsky Prize, which has gone unclaimed since it launched in 1980 -- with the best efforts barely leaving the ground. But the University of Toronto-based team reckons it has the chops, with two PhDs aboard and Snowbird, the first successful human-power ornithopter, under its belt. The Atlas will feature four rotors like a 1994 design from Japan, which flew for 19 seconds, a simple and stable configuration that required less pilot power than other models. The would-be flyers have rustled up more than $27k toward the $30k target with 35 hours left, so if you'd like to help out -- and fulfill the dream of eccentric inventors everywhere -- hit the source link for details.
