As far as the tile roofs, they last a long time. It isn't the tile that is the issue, it's the felt (or paper) underneath that gets replaced. Mine is 25 years old, has not been replaced yet. Some neighbors have had theirs redone, but many have not as yet. 04-06-2011, 12:00 AM.
Particle Accelerators Could Be Used to Produce Energy (and Plutonium) Particle accelerators, which are not renowned for their real-world applications, could in fact be used to produce energy, according to a 34-year-old research paper that resurfaced this week.
For this reason, much of the accelerator is connected to a distribution system of liquid helium, which cools the magnets, as well as to other supply services. The Large Hadron Collider is the world's largest and most powerful particle accelerator (Image: CERN).Thousands of magnets of different varieties and sizes are used to direct the beams around the accelerator.or this reason, much of the accelerator is connected to a distribution system of liquid helium, which cools the magnets, as well as to other supply services.
