AKL,

Be careful not to come into contact with this form of gas . It contains the very rare and exotic elements of DO2; danger dioxide . Scientists won't disclose this, but it's known to stimulate a person's erogenous zones.

Great photo of a squashed Halloween mask. You can make out the mouth and nose at the bottom but only one eye is discernible. Either that or some quick shots of fresh road kill. Keep up the good work J.D. Good to see you are getting out more.

"(night vision is basically a camera that detects IR light). "

Let's be careful in using terms so we don't confuse anyone - there are actually three types of technology used for night vision:

The technology that most people call "night vision" works by amplifying the very low level of visible ambient light that our eyes cannot detect. A better name for this technolgy is "light amplification". This technology creates the classic "green" scene images that we've all seen from the military. The military likes this approach because it is passive in nature and will not give away a soldiers position.

Alterntively, other night vision devices use an energy source (just out of the visible range in either near-wave IR or UV) to illuminate a scene in a wavelenth that humans cannot see. This is an active technology and is kind of like mounting your old hippie black light from your garage to a camera that detects the black light. Obviously the military doen't like this approach because this type of device can be easily dectected by an IR or UV sensor which would immediately give away your position but it is useful for other situations and can provide very good quality images because there is an actual source of energy illuminating the scene. These images are characteristically black and white (not green) with a bright spot (more white) where the illuminator energy is strongest.

Otherwise, true IR cameras detect heat or thermal energy and can be used for night vision but only objects with different temperatures can be resolved. This can be helpful when searching for a Sasquatch (hot) in a forest where the ave temp of the background forest is colder than the Big Foot or any other hot blooded animal but many objects can go undetected or unresolved because they are same or close to the same in temperature as the surrounding background (e.g. cold blooded animals or made made objects). These images are recognizable by their wide range of full colors (red, yellow, green, and blue) with bright red being the warmest and dark blue being the coldest.

The other issue that is rarely concentrated on is how burning fossil fuels at these global levels dumps unprecedented amounts of mercury into the enviorment. That ends up in the air you breathe, the water you drink and the fish you eat. Warming or no warming.

to say nothing of all the mercury in those new ugly light bulbs we are now going to be required to buy. Just don't break one when the children are around or you be in for it. Keep a chemical suit ready for your home cleanup. Looks like we are all dead in the end anyway. :ah:

the amount of mercury in a CFL is around 125 times less than the amount of mercury used in your old-style lever operated thermostat. have you replaced those yet?

In addition to carbon dioxide fossil fuel combustion emits sulfur dioxide and nitrogen dioxide- all of which makes water more acidic, and it all comes back down as acid rain, which has proven to change environments drastically. There are plenty of reasons to move away from fossil fuels (and combustion in general) other than global warming.

Then can we assume you have gotten rid of all your vehicles that use fossil fuel? How about your electric, does it come from coal or oil? If so have you disconnected from the line. Kinda like Al Gore riding around in his private jet complaining about carbon footprint. If all of you advocates would give up your use of fossil fuels we all would be better off, no? Until that time....

Oh absolutely, show me a viable option and I'll jump on it. Unfortunately, no viable option exists. But we all know that, the point is that green technology should be emphasized and innovated on. You can't just switch the entire world onto non-carbon energy overnight.

Also, that political argument does not work as an attack to the scientific fact that fossil fuel burning is changing the world dramatically.

Thanks for the information, I'm not very educated in military technology myself and it was unwise to use it as an example. However, I think you understand what I was trying to say.
