Comment Let's see... (Score 1) 221

tires heat up a little, so this tire converts the increased temperature to electricity to recharge batteries. How much does a tire heat up? How much energy can be extracted from that heat? How complex is the mechanical coupling that moves that recovered energy to the battery?

Sure you can get some electricity from a temperature difference. It might be enough to run your wristwatch. Recharge an electric car's battery? Yeah, sure, youbetcha!

Comment Re:Wrong kind of drone? (Score 2) 280

Don't be silly!

Have you ever seen the view from a tall building? How about from an airplane? From 18k feet you can see a lot of ground. Predator drones can stay up for many hours (maybe even days at a time).

Parrot drones fly at rock-throwing altitudes for about 10 minutes at a time. How many thousands of them (and people to operate them) do you think it would take to view the same area as one predator flying at 18k feet?

Comment What kind of counterfeits are they worried about? (Score 2) 207

The part being copied would have to be something that is unavailable otherwise and/or very costly to be worth the time/effort to counterfeit it with a 3D printer. It would have to be something for which the market is very small but very willing to pay, because if the market were large, 3D printing wouldn't make sense- you'd fabricate the counterfeit in a way that's more cost effective for producing large quantities (and would probably give a higher quality result).

Maybe parts for exotic sports cars? But who isn't going to inspect and quickly know they're looking at a fake? What exotic sports car mechanic is going to risk his reputation by buying and installing counterfeit parts?

Jewelry? Too much scrutiny applied there, too.

Nope. Anything that costs a lot is going to be scrutinized. Anything that doesn't cost a lot isn't worth counterfeiting, especially not with a 3D printer.

Comment I drink your milkshake (Score 1) 168

If there's a drone directly over my property it probably isn't looking into my home, but my neighbor's.

If someone wants to look into my windows with a drone they are probably going to do it from some distance away from my property, thus affording a better view. Unless you can get your neighbors signed up for this you're screwed.
