    I worry when i go to the BANK to deposit cash, and require change (gold coins only, dead simple mental maths) and the teller needs to use a calculator to work it out! And we let these people look after our money?


    Speaking of the electric light bill, how is CERN powered? They must go through a lot of juice...

    CERN pull power from the French and the Swiss grid. I worked out that they use at least some 36MW just in cooling the the LHC.

    Power supply for them is a huge problem, so much so rather and expanding the computing centre they now have multiple Tier 1 computing centres in other countries because they did not have enough power left in the grid for the computers and the cooling towers.

    Heading off on a tangent...

    Speaking of cooling the LHC, they cool it down using liquid Helium, but with a little trick they can get closer to absolute zero. The trick is to mix in Helium3 with the Helium4 and flash off the He3 to get that last little bit of cooling..
    The interesting bit it that Helium3 is very rare on earth, and what there is is produced in nuclear breeder reactors, the current price is around $2000 per liter..

    Now the weird bit... evidently the moon is rich in He3, and the chinese and others are supposed to be well advanced in planning mining operations on the moon just to harvest He3 for nuclear fusion reactors, no I'm not kidding... Race to the Moon for Nuclear Fuel

    A bit more expensive than the stuff we put in balloons then.....8 cubic M cost us about $380. BUT there has been shortages of late and the price has been going up. Apparently most of the helium on earth is not native, it comes from space. It has slowly built up over millions of years and now we are bottling it and dispersing it.

    When CERN shut down the LHC for luminosity upgrades they sent their helium back to their suppliers for safe keeping. fingers crossed that it is still there when they are back online.
