Cool, quite literally

New type of solar structure cools buildings in full sunlight | phys.org, new technology based on nano tech material that tunes reflective / radiative properties of a surface, so efficient that its as effective as air conditioning powered by a similar sized PV panel. But this passive tech does not need to face the sun, radiating the heat back to space through the narrow band of frequencies that provide a window through our atmosphere.

Your first e-vehicle could be an e-bike | Machine Design

Your first e-vehicle could be an e-bike, I was thinking this very thought watching some guy in full gold wing touring togs whining along on his bright metallic red red scooter. The monocoque bodied eBike with 0-60 times as good as a good sedan and space for modest shopping would be an ideal 2nd / 3rd vehicle, useful 80 to 90% of the time.

Gyro stabilization makes the vehicle practical, if reliable enough.

China Aircraft Carrier / Navy needs proper context

Wired and others have been nattering about the Chinese carrier, it’s nascent flight wing, how crappy the hardware is, how hard the job is, etc, etc. working to defuse the China threat they think is being blown up by the Pentagon and congressional hawks.

Look at the two pictures above, the time from first flight to rational threat back ‘in the day’ was a few years, the big gun guys were laughing the whole time. That Fighter struggling off the Lianoning is a threat today if need be, and you do not have to impress an admiral to be able to sink his fleet. No it’s no realistic threat today but don’t make the mistake of equating little with none, the US capability with the capability required to be a threat, or today with forever. The US CVN capability is essentially static or downtrend, China is on the edge of asymptotic rise, with a century and millions of man years of prior experience across the world to pull up on. As other articles in have discussed, what really is a CV in the 21st century? So how long could it be till a Chinese CV threat is more than a wild card? Not long is my estimate.

Cool tech at NASA cutting manufacturing time from 9 months to 9 days. This is for the STS Senatorial(pork) Transportation System that I’ve no love for but proving tech like this is one of the ways that government R&D tax dollars provide broad value since success is not squirreled away as a trade secret.

Going quietly (slowly) into that good night

Wired, Danger Room piece on after the aircraft carrier.

The Montford Point landing platform is essentially a cut down supertanker ( the predecessors of today’s Ultra Large Crude-oil Carriers, ULCC) which can ballast down and ‘lean’ so hovercraft can come aboard in open sea. One option is to similarly use this type of craft or similarly modified commercial hulls as cheap almost disposable carriers as needed. A sub divided double hull tanker is very hard to sink and the hull plates are sufficient to keep out small arms and splinters. Plus armoring and fire fighting kits are available and cheap today. The ‘fighting’ bit’ would essentially be a mod kit (a skin) that can be updated, moved around, even stored ready for war, the hull could be almost any commercial large bulk carrier. Heck large container ships are very fast today as are some RoRos, so you don’t even lose much strategic deployment speed.

Why Silicon Valley Is Winning the Robocar Race

By Virginia Postrel Mar 17, 2013 6:30 PM ET

Good short piece, I think it’s pretty obvious but needed saying. Articles out of ‘Detroit’ talk about decades, about lawyers killing it, about the joy of driving, no the joy of striving. In fact this is another area where differential change is required, relative change, change suited to the specific here and now of the individual or local group, not society writ totalitarian.
