You can't keep radiation levels a secret !
All sorts of people will be measuring, near and far. After Chernobyl, for example, the pharmaceutical research site I worked at in England ( >2000km away) spotted the abnormal levels very quickly because they were concentrated on ventilation filters. It's so easy to detect extremely low levels of ionizing radiation
"Steam which has been superheated as in a reactor core can break up into hydrogen and oxygen"
NO IT CAN'T
People have been going 2H20 > O2 +2H2
The equilibrium for this reaction lies HEAVILY to the left at reasonable temperatures
Water only dissociates to 3% hydrogen 97 % water at 2000 C . The water has to react with something to generate significant amounts of hydrogen This would seem to be zirconium in the fuel rod casings by all accounts
He's quite correct water doesn't break down appreciably even at 2000 C. Even then it's in equilibrium with only a small percentage of free hydrogen/oxygen.
The only way of generating sig. free hydrogen is to react the water with some material such as zirconium as others have mentioned
What cross-grained moron downvoted this.
It's a FACT - my wife's TOURAN is the same - for that matter every car I've ever owned has been better than 20 mph /1000 revs (since 1969). My motorhome at 3.5 tonnes does ~30 mph/1000 revs.
For goodness sake disagree with an OPINION but this info. is available on VW's website
"They point to studies suggesting that a 10km/h reduction in speed saves closer to 5% on fuel rather than 15%. The government's own figures suggest it could forfeit large sums in tax revenue due to the fuel savings. And the bill for changing the road signs for just four months runs to 250,000 euros."
Mind this is the same BBC that has 130kph translating as 75 mph or 81 mph on two adjacent lines
Get yourselves a handful of 18F PICs (http://www.microchip.com/) and a programmer. It's easy to set one up to do all sorts of jobs and hook it up to a PC via a serial or serial/USB converter. One of mine is providing me with info about my house (temperatures etc.) via a small server program on my fileserver even though I'm 800 miles away in Switzerland.
Another is emulating a serial port chip on my homebrew FORTH 6809 system.
Cheap, robust, versatile and available in 0.1" pin spacings so PCBs can be made using laser printers by printing the mirror image onto photo paper, ironing that onto clean copper board, soaking off the paper and etching the board.
but it's certainly rather poor. Very fit, muscular athletes are often rather high BMI but low body fat
4 points.
It's better to be the 'correct ' weight AND fit, but it seems better for health to be fit and rather overweight than unfit and 'correct' weight.
There seem to be better measures of weight, BMI is just the easiest to measure but studies have shown that % of body fat or even just waist measurement are better predictors of poor health outcomes. Very fit, muscular athletes are often rather high BMI but low body fat
Exercise does seem to be VERY important for long-term good health.
Because of chance & biological variation lots of people will experience different outcomes.
PS: Could it be all that food they eat down south?
Seriously the combination of even a little too much food combined with too little exercise is enough to explain it all. A single slice of bread needs a mile of walking to burn it.. Eat just 100 cals a day over what you need and thats 36500 cals a year and that's ~4.5kg of excess weight. & that's ~1.5 -2 BMI units (OK BMI is a poor measure).
Yes I appreciate that - I was just puzzled by the comment "but he is very enthusiastic about the Atom family, particularly now that it runs 64-bit code," which makes it sounds as though this is a recent thing.
I built the file server when I needed it - I'd much rather have an even lower powered one.
but irneb's post I was replying to said :
"....as it would be to hold enough H2 in a canister at thousands of atmospheres to get it into its liquid form "
I was merely pointing out that hydrogen can't be liquified by pressurization. Further even liquid hydrogen has a much lower energy density than hydrocarbon.
By the way considerable research is being done into the use of cryogenic hydrogen by BMW and others
I'm no fan of using pure hydrogen as an energy carrier unless the numerous practical problems can be overcome, maybe by on-board generation from precursors (formic acid for example -which brings it's own set of problems)
Unfortunately even fuel cells have a low-ish efficiency (~50% tank-wheel) esp.when combined with the efficiency of hydrogen production. No doubt some considerable improvements remain to be made.
