    Default Laws of Physics changed in 50 years?

    I was reading an article about a well insulated house and came across this, "Space heating is a Daikin reverse cycle air conditioner. Amazing piece of gear, has a coefficient of performance of 5. i.e. 800 watts of electrical energy in = 4000 watts of heat out."

    I and many others were taught that energy cannot be created or destroyed. Has this changed in 50 years?

    If Australia is a democracy why, then, is voting compulsory?

    "What has changed between the arrival of the First Fleet and today?"
    "Wearing leg irons is now not required."
