Metal Velcro
RotJ writes "British scientists have developed technology that can grow structures up to 2 millimetres high and 0.2 millimetres in diameter on metal surfaces. Dubbed Surfi-Sculpt, it 'will act like ultra-strong Velcro to form much tougher joints between metals and lightweight composite materials'."
Really? Strange, since the modern zipper was invented by Canadian Gideon Sundback.
One line blog. I hear that they're called Twitters now.
Did you read the article:
The projections could be used to encourage bone to grow onto artificial hips. They could also be used in electronics to produce heat sinks of just about any shape.
it's not like dragging your finger through clay though
when you use the beam, then drag it, the metal will accumulate near the start point, not where the beam is
in all, it's a pretty cool application of physics, really, and deserves this patent
at least they're not trying to patent electrons

"Dance says his early tests show that these joints will last far longer than current composite-metal joints, which are held together by adhesives."
It doesn't "use lasers to melt the metal and tease the structures into being".
The process uses a beam of electrons; a laser is beam of photons. The process relies on surface tension to form the structures; they form on their own and are not "teased" at all.
You are neither interesting nor informative. I was going to mod you down, but because this process has tremendous commercial potential, I decided that it was more important to point out the facts are not in agreement with your summary. You're welcome.

The gains would be much more noticable in a system where the bulk of the coolant action comes from a high specific heat with low fluid motion, as in a liquid cooled system. It would increase the efficiency of still air, but could end up decreasing the efficiency of forced air.
