I have seen exactly this problem when I am compose-typing, never when I'm copy-typing. My guess, like yours, is that the part of the brain that is doing the thinking, is in someway communicating with the part of the brain which does the typing, through a mechanism that is similar to the way the brain processes heard speech. I'm glad that you've posted this, it's nice to know that the phenomenon is not just in my imagination. Thanks for that.

If you're interested in printing your own, I'd recommend a visit to a quality camera shop. Ink jet printers with archive quality inks and varnish, and appropriate acid-free paper, creates photographs that will last for a very long time. I recall this kind of printer being available at my local camera shop for approximately AU$180. The inks work out to about 10 cents per A4 page (IIRC).

Kudos to you. I changed my habits and retrofitted my home with insulation, solar-water heater, awnings and a rain water collection system (with a mains pressure pump). More recently I've added a 1.5kW solar system, with the money put up by the electricity retailer (on a two-year interest free loan). Because I had my own consumption down to such a low level before I went solar, I find that my system generates twice as much electricity as I use. The system will be paid off in two months, and I'm currently sitting on a $600 credit with the power company. These things are achievable now, and you don't need to live like a cave man to do it. I have whole of house air-conditioning, space-heating, computers, television, internet, etc. Individuals can make a difference with a little bit of thought.

It is part of the hidden cost of nuclear power plants. If nuke plants paid insurance, the power generated would not be cost-competitive with other sources. Therefore governments all must give all nuke operators an iron-clad "hold harmless" clause, guaranteeing to make the pubic wear the cost of any "accidents". Are you starting to understand why so many people despise nuclear power yet?
