The lighter a vehicle is, the more efficient it is.

Yes, they sit around a lot of the time, which means at work it would be great to charge them in the parking lot with solar power, that would be half of the power requirements met for free (assuming they were fully charged by the end of the day), but when they get home they would need charging again.

Moving weight around takes a lot of energy, and batteries are *heavy*, ideally an electric vehicle should have just enough battery to get you where you need to go, plus a little for unplanned emergencies. The extra power it takes to log around heavy batteries is also wear on the batteries themselves, so not only are they burning extra energy to move themselves around, but they're also wearing out faster.

If you want a battery at the home to store up off-peak or solar power for use later, then it makes a LOT more sense to have it stationary at the place you need it, instead of lugging it around with you to work, the grocery store, your daughter's dance recital, etc.

You have to send a picture of your genitals. If there's hair, you're in. If there's no hair, they go to jail for having kiddie porn.

The weather has never been predictable, life on this planet is capable of dealing with changes in climate. Watching trees adjust their growing cycles in reaction to changes in the entire climate isn't scary, it isn't bad, it's proof that they can handle a little change even if it scares the crap out of us hairless monkeys Plants have more CO2 which makes them healthier, they have longer growing seasons, which makes them bigger. The "Green" movement is literally fighting against something called "Global Greening" right now, and if that doesn't make you laugh, then you just need to chill.

Dumpster diving, museum is likely on public property:

And there's no law against owning moonrocks:

Does anyone else thing the moonrock collector guy is whiney? "No fair! if can't keep moonrocks, then you can't either!"

some guy using the name TimothyHorrigan made one change that was almost immediately reverted.

I'm no Palin supporter, but this isn't news, it's just sensationalism.

awesome, the anchor tag is empty, just "a", not "a href=..."

I'd love to see 3D printers become more common and affordable, and see open source move to physical objects (like an open-source car!)

Heh, maybe you should do a little research on rapid prototyping. Usually the printed material is plastic.

I think this is a great idea. Not only should we come up with good theories, we should test the best one on an asteroid that is relatively close, and have the necessary preparations done for a future quick-launch mission in case this ever does happen.

Because, after all, the amount of time between when we hear about an asteroid on a collision course and when it would actually hit the planet is likely to be a LOT less than the amount of time it would take to ready a space mission (or build a special rocket, or borrow China's anti-satellite laser!)

So, what, we're supposed to have a different password with special characters and nothing significant to us (like dates) for each of the 150 online accounts we have? Oh, and if we write down the passwords somewhere so we don't forget them we're dumb too? Whatever! Maybe if we all had photographic memories that would be a realistic options, but there's just no way it's going to happen like that.

It's just a crappy system, we should be using public key encryption with our private keys stored on a USB key - or some other similar scheme, where we don't have to memorize a million randomized passwords in order to not have our identity stolen.

if you look at it another way, you can turn your laptop on it's side and you're gaining vertical pixels while losing horizontal ones, make it *better* for reading A4 ;)

"Transplant" means to move from one body to another, they likely meant "implant" unless some robot somewhere literally gave up a component to save that boys life ;)

Mirasol? Really? A technology that's not even on the market yet? Why not go with the already available and commercially viable pixel qi screen tech? It' the best of both worlds, a dual mode screen for indoor and outdoor use! And you can already get one! Just add touch-screen capabilities and you have the perfect tablet.

Actually, if you're going to store them for a long time (years) without running them, you'll probably need to keep them cold.

I hear (from someone that kept HD's on a shelf for years) that the oil will run out of the bearings if the drives are left sitting for years, causing the platters to freeze up when they were turned on.

Admittedly, this is old information, and who knows what the new drives do (maybe they have better seals?) and I'm not even sure that keeping them cold will help, spinning up the platters for 15 minutes once a week might work too.
