Nice shot of andromeda there at 1:14

Was this shot through your meade?

For people complaining about the Sims 3 running slow on a comparable MacBook, you must realize that the sims 3 was never compiled out for OS X. It is actually native code running inside a virtual wrapper. Transgaming supplied the wrapper, which is decent but not the fastest. It's basically identi...

That's the absolute biggest low temperature differential stirling engine I've ever seen. It's just not designed very well. Two pistons? That's part of the problem, because they both share the same displacement area. That just adds friction, and LTD's need to be friction less.

It looks like you used rustoleum enamel paint--I've heard of people doing that. It needs to be sanded down with each layer or you end up with that orange peel texture. Then you'll need to clear coat it if you want it to look shiny. You can't do it for $50 but probably could with $100. There's not...

'kinda upside-down like,' so does that mean upside down but only kind of? Maybe halfway upside down?

You can't compare a tablet to a netbook. These are two different platforms, both have advantages and disadvantages. One has a touch screen, one has a keyboard and trackpad. One runs on a mobile version of OS X and one runs a full OS of windows. Just because they both connect to the internet and h...

They aren't useless for work. The original comment was made awhile back. The problem is LTD engines can't do large amounts of work. They are more for demonstration. It only shows the concept at work. Given more heat on this, you could belt the flywheel up to a small dc motor and produce a small a...

Cool, so if she starts nagging you just hit the sleep button.

I pee in the ocean.

This is the reason the people with less assets can't compete. You are inflating the difficulty rate massively. But fuck it right? You'll never see your investment return on that. There's enough equipment there to buy a nice new CAR to get you to a JOB.

Night Vision devices work on amplifying existing light. You can't make something from nothing. That's a common misconception. Taking your nvg's into a light tight sealed room and turning them on expecting to see like the sun is blasting it's warm rays in there is completely wrong. PVS-14's use th...

It's clearly not that dark because the gentleman on the left saw the tree in front of him and braced the tree with his hand for support.

Love Monster much?

Ray's sense of humor...oh wait it needs to die first.

Ok now go build a real car.

Fail...you didn't hit the self destruct button.

Lemmings detonation timer hits 3..2..1..

This is what happens when you forget to turn off the stove before vacation.

That dude apparently plays too much grand theft auto.

@PoliceOwn Don't you remember? He was trying to do that for the longest time--you'd know this if you ever watched.

It's like hanging out with the ugly girl so the hot girl thinks you are a nice guy--except you don't get he girl and you end up with an ugly car.

It can't be real because there would be discoloration in pure white snow from bodily fluids

This isn't free energy, and there is no such thing as free energy. Energy is constant. They are just utilizing the work created by magnets and converting it into a usable source of power. Eventually the magnets lose their energy, but the amount of work required to build this machine and the creat...

Dan, I see the idea here and I think the stirling engine is a great idea--however I don't have the tools or technical knowledge to actually construct one. However, I digress...couldn't you improve cooling by making the flywheel a fan instead of a solid piece of metal? It could direct cool airflow...

I appreciate you pointing out that solar panels still collect photons at night under a blazing full moon but they probably aren't even producing enough voltage to pass the blocking diode. The best solution gathering wasted energy at night is to use wind turbines.

I am very concerned about global warning.

@aross345 You didn't answer this persons question so I will--this would not be a good way of powering an RC car. It requires lot's of heat to make the engine rev up, and being this is the only way to throttle up and down the engine, it means you'd have to find a way to make a heat throttle. The n...

As cool as the video was, it's not faithful to physics at all. Obviously, that was not an asteroid but more a dwarf planet.

You play COD like a Jew. I'm surprised you are giving anything away at all.

This is the american version scary japanese music.

Is this before you met Donna, or after?
