In any case: 1. glycol will cause other problems, and 2. it takes months to engineer something like this.

Anyone who was participated in a tradeshow or invited in an important customer has experienced this.

This is incredible. > No, this is what happens with prototype machines in cutting-edge technology. Something always goes wrong. See, for example, the U.S. Vanguard Rocket flight tests: http://www.youtube.com/watch?v=JK6a6Hkp94o Things often go catastrophically wrong. That is why it is a bad idea to fire up an untested 1 MW reactor in front of a crowd of dignitaries. You are likely to kill them. People who use ordinary technology such as automobile engines, electric lights or computers have the notion that technology is highly reliable, and all you have to do is turn it on. If it does not work reliably, people think there must be something inherently wrong with the technology. Any machine eventually does become reliable, but only after hundreds of thousands of hours of testing, after people manufacture billions of copies of the machines, and machines have been turned on trillions of times. In the early years after automobiles, electric lights and computers were invented they were unreliable and unpredictable. - Jed
