Taken from BBC's Wonders of the Solar System, Professor Brian Cox explains a beautifully simple experiment to calculate the amount of energy radiated by the sun using a bucket of water, a thermometer, an umbrella and some maths we all learned as children.

  • @Tnias13 Because oil is the concentrated product of vegetation storing solar energy, being compressed for millions of years.

    A kilowatt sounds like a lot of energy for a square meter until you realize how much energy is released by burning gasoline. My car generates up to 200 times that much power from a small steam of gasoline coming out of six tiny nozzles.

  • ...and that's not even accurate, because it doesn't take atmospheric absorption into account, or reflection from the tin, or other kinds of radiation that doesn't heat water, like neutrinos...but yeah.

  • @TrampVamp totally agree!

  • It's funny because most people don't think you can waste sunlight.

  • @animandolasletras

    and Brian May is an astrophysicist!

  • Finding it difficult to deal with how adorable I find this man.

  • He loves physics, so do I. We're made for each other Brian.

  • The advancement of technology is the limiting factor.... obviously. You can't see before you have eyes, you can't run before you have legs.

  • Brian May and Brian Cox, rock and sicence and mmmmmmmmmm
