What time is it?

The sun was shining ... we were thinking about Maui slowing the sun. We were reminded about the history of time, clocks ... and sundials. Can we tell the time using the sun?

We discovered that we can tell the time using a sundial ... on a sunny day ... but that the shadow moved "the wrong way" (anti-clockwise) because we live in the southern hemisphere!

Now that this time has passed, we're waiting for another sunny day to find out how challenging it is to harness the sun's energy.
