You all forget one eenzy weenzy fact. It takes 6 units of plant protein for US to make 1 unit of meat protein (in our body-mass) too! So when we eat steak, we are getting concentrated protein, or we'd have to eat a LOT of bran which also takes a lot of energy to grow, be processed, packaged, bought, delived and eaten.

A double-wammy win! That's it! In order to make the cow walk it will have to be fed (kinda carrot on a stick) this would mean the food will have to be brought to it. Much too much energy waste there. So places where this MUST BE DONE ANYWAY, like in winter, these treadmills might just work. Even to offset the cost of warming them, or maybe the walking will make them warm themselves. A double-wammy win!

How do they breathe and receive food? even the cells of our bodies need circulated blood in vessels to receive oxygen and food. How would they do it if the weren't attached with vessels in between?

Thank heavens! Someone who sees sense and knows what he's talking about! What almost all don't realise is that you are only thinking of one thing at a time. If a high-speed photo were taken of a musician's brain it would be seen to be, for that moment, concentrating on ONE thing. But alternating between the tasks at light speed. Like a CPU. They are saying that we are like two CPU's RUNNING IN PARALELL. Geditt?

Most are missing the point entirely. A computer can only do ONE THING. The on/off or hi/lo thing. But it can do it very quickly. The research says we can do TWO things AT THE SAME TIME! Like two processors running in parallel. Geddit?

When the meanings of words change for most of the population there is a danger because people ASSUME you mean alien craft, not a possible plastic packet, when using'UFO'. As with the 'organic vegetable' craze. ALL vegetables are organic, and any farmer can sell them as such. Whether they are organically GROWN is another matter entirely!

Yes but won't the sunlight reflected back heat the atmosphere AGAIN? On it's downward route, then off the Bubbles (heating them as well), then re-heating the atmosphere again. What the 'ex-spurts' don't realise is that the sunlight entering our atmosphere will dissipate it's heat one way or the other, if one does not reflect it all the way out of the atmosphere, back into space!

Why is it that 'Ex-Spurts' are so narrow minded? The Christmas Tsunami was the result of volcanic activity in the Indian Ocean. The Himalayas are fold-mountains caused by India moving North and China having non of it. The epicentre of the Chilean Quake rose more than a meter (3 feet) in a matter of seconds. What goes up can come down. Even a sandbar island.

What about LEISURE SUITED LARRY IN THE LAND OF THE LOUNGE LIZZARDS?? Surely one of the first 'talking' interaction games?

"Leisure Suited Larry in the land of the Lounge Lizards" made me buy my first PC after having Commadors and ZX's, etc.

Before my C64 I had a VIC2o, but the funnest was a Heathkit DIY computer that had a 'HIGH LEVEL LANGUAGE'! It was called TINY BASIC and tiny it was. It only had 12 commands! Was like explaining to someone over the phone what to do, but only having 12 words to explain it to him. Yes, it was EXACTLY like that!

Remember how hungry you were after writing a two hour exam at school? The working brain is an energy drain. It's a fat burner. Watching a movie pulls the brain with it, you use as much energy as you would sitting on a park bench watching traffic. Power to the Puter!

It is a well documented fact that the San (Bushman) marked individual ostrich eggshell containers as proof of ownership. These were mostly used as water containers and buried in areas where there is no surface water for long periods of time (eg the Kalahari Desert). The San have been doing this for, quite literally, time immemorial and, indeed, do so to this very day. It must also be remembered that the ostrich eggshell is NOT 'fragile'. They could store water for hundreds of years if the opening was sealed with fibre and melted bees-wax. Far longer than any wooden, skin or earthen-ware container would. Also, in a cave deposit, OSTRICH eggshell will outlast pottery, even bone, only stone will survive longer than Ostrich eggshell. So when is a symbol of ownership deemed to be 'writing' or 'art'. Are we to now say these inhabitants weren't illiterate? The Howiesons Poort shelter gives it's name to a specific tradition that corresponds with the European Mesolithic (in South Africa called the Middle Stone Age), which goes back to 80,000 years BP. That's a LONG time ago!

Now we know why gold was so important to civilisations world wide. Maybe that ET thing is not so far fetched! The Nazcar lines etc?
