We got solar panels installed about 6 months ago. I did the math, and figured they’d pay themselves off within 5-6 years. Your results may vary.
I’ve been tracking very carefully how much they generate. Watching the numbers tick over produces some strange ideas in me sometimes. For example, I started wondering – if all the energy from the panels were converted into saffron, how much saffron rice could I make?
If you still have time to make some hand-made Christmas decorations, check out this amazing softwar: Ornamania. If you don’t want to download the software, there are patterns you can download and print, and an instructional video.
Finally, just to close off the last Monday Morning Math for 2013, let me mention that my wife and I have a new book available on Amazon.com: The World’s Biggest Animals, based on our website of the same name, available only for Kindle. If you don’t have a Kindle (and it’s not on the list you sent to Santa), youi can also get Kindle Apps for Apple and Android devices.
If this book sells well enough, we will probably work hard next year making lots of books on animals, math, maybe other topics. If that’s something you’d like to see, tell your friends about this book!
In the meantime, have a safe and happy Christmas and New Year, and I’ll see you in 2014!
Yours,
Michael Hartley
