Sorry, Remek, I see you did mention the 180 slip. But it's still sad that predictions seem to exclude the notion of a totally metric planet. Paul Trusten, Reg. Pharmacist Vice President U.S. Metric Association, Inc. Midland, Texas USA www.metric.org +1(432)528-7724 trus...@grandecom.net
[USMA:52679] news from the year 2050
But, Remek, the announcer said that the 10-kilometer-high building was built to withstand wind speeds of 180 MILES per hour. Oops! Seems that futurists from countries still struggling with metrication even have difficulty (or is it reluctance?) predicting a fully metric future. I suppose it's all in the sexiness of the story, which apparently excludes the work required to think metric. It is easy for the BBC to predict the banning of meat sales, the first off-earth human birth, and the disappearance of Mandarin, but, darn it, [snaps fingers] they just can't find their way to omit the measurement system that should also have gone the way of meat and prisons in their thinking. They are literally unable to measure their predictions. Paul Trusten, Reg. Pharmacist Vice President U.S. Metric Association, Inc.

Everest is made. Shortly after, though, they drop the ball an state that the tower can witstand winds of 180mph velocity. Oh well. Remek

Pressure cookers should have safety devices to prevent them from exploding. Although we do not have a pressure cooker at home, I remember that my mother's pressure cooker had a rubber stopper that would dislodge should the pressure rise too much. On reading the account, it occurred to me that the pressure cooker used in the explosion could have been bought in country that did not demand safety valves on their devices. (I assume that in the US it would be illegal to sell pressure cookers without safety valves).

Ok, let's get the record straight here! I've used pressure cookers a lot and they have safety values, but they only allow the pressure to release fast enough to avoid normal overheating. An aunt of mine actually had her pressure valve blow and it plastered the ceiling above the stove with the food contents inside. However, a bomb going off is certainly not going to be abated by a pressure relief value!

Agreed. I have never activated the safety in mine but it is a frangible section in a replacable screw-in fitting. I estimate the failure section to be some 3-5 mm in diameter (not exactly clear where it would fail). It would release steam as fast as a stove could form it. I'm not sure it needs to be replacable. I've heard most people who have your aunt's experience never pressure cook again. :) They speed up cooking around 3:1, but they are at least slightly scary. Pot roast in a hour makes it worthwhile. Many brands available in the US are imported, and marked in liters. A bomb blast would create too much overpressure for the safety and blow the cooker apart regardless of brand. Steam pressure builds slowly based on time to heat the water. It may take 15 minutes to get to nominal cooking pressure, moreless the trip pressure, if it is half full.

My mother used pressure cookers all the time when I was little, to pre-cook spare ribs for barbeque on the grill. She said it made them less greasy. Yes, they all had rubber relief valves, but I'm sure a terrorist could weld that over.
