As others have said, California is going to be in a world of kharmic hurt come this summer considering its going into one of the worst droughts on record.

How do they keep the solar cells from overheating? They get a lot less efficient as they get hotter.

That simulation was really cool. I wonder how many particles they used, whether they allowed shattering or just energy loss due to inelastic collisions, and how long it took to render.

And it's mostly the heat from the turbine that's dominating the photo.

Don't forget that it's not triangulated, so even if the tubing were round, it would flex like a bow. "Laterally rigid and vertically compliant," heh.

Yeah, congratulations for going off track there.

Yeah, it seems braindead to have to tell a website what the card is, but I think it's also to help the user figure which card to use. Rather, if the radio boxes are for Amex, MasterCard, and Visa, then you know you can't use your Discover card.

Great, no false positives. Now, what about false negatives?

Yeah, it needs a courtesy mode- back out to let out the car next to it, then park back in again.

What's interesting isn't the fonts, but the technology behind all this.

Good thing the adhesive is over the whole back (vs. just along one edge) or else this could have meant a resurgence of the 3M "Scotch" brand http://en.wikipedia.org/wiki/Scotch_ta…

The rigging may have been from something else- certainly if it were for that purpose, they would have had a better launch area, say a platform that sloped down more than the zip line sagged.

If there's no better material, it sounds like these components are optimally designed.

Meh, I've got all those individual pieces in a box in my garage.

These cheap lights are now half the price that they were last year.

Wasn't the iBOT wheelchair the predecessor to the Segway?

I've got to RTFM. Yeah, 3D printing is great for complex inner shapes, but I'm not too sure about for orifices, though I guess there can be another drilling process after that.

A solid rod of iron weighing 300 pounds and measuring five inches in diameter would then be 4-1/2 feet long. Seems like it would be an axle for the wheel. Reduce the density by about 20% (made up number) to account for air voids and you know, actual mechanisms instead of solid iron, and that rod would be over 5-1/2…

Yeah, because if you have the hubris to claim room temperature superconductivity or cold fusion, we all know how well that goes.

You mean, like a regular old Maglight? (oops, saw that that's already been answered.)
