Look for the 123 ft wind turbine blade

Going to Minnesota's State air? Don't miss the Eco Experience in the Progress Center building. Look for the 123ft. tall blade from a 1.5 megawatt wind turbine. It is at the NW corner near Snelling. Like everything served on a stick, this could be "wind on a stick".

Minnesota Public Radio website has a slideshow of what you will see. The exhibits within have a strong emphasis on energy efficiency...how to use the energy you do use carefully. Below is a breakdown of topics and activities. Each link will take you to more information. Also here is a map (pdf).

The Eco Experience is an opportuity to talk with and learn from regional leaders in energy conservation. The University of Minnesota's solar race car is there as well as lots of ideas you can use in your homes. Maybe I will see you there. I plan to volunteer at the University of Minnesota – Initiative for Renewable Energy and the Environment (IREE) booth. The Minnesota pollution control website has links to other participant websites.

Sneaky videos
Sneaky videos

Cy Tymony, author of the great book, Sneaky Uses for Everyday Things, is sponsoring a contest for science fair projects on conservation. Just make a how-to video about your project on alternative energy or conservation, upload it to You-Tube, and you can be entered to win a DVD player, a portable MP3 Player with thumb drive and a USB WiFi adapter. If you post your videos make sure to add them to the Recycle Reuse Rethink Energy Usage group.

I'm excited for this project because it not only inspires kids to hunt out alternative energy and conservation ideas but also encourages them to document their work. This will help support the idea that science is a process involving research as well as communication.

To get inspired check out the videos that Cy has already posted. My favorite is the cool hidden pocket how-to. I know its not energy focused, but it's still a great example.

How many seconds are in a day?

Can you picture how many seconds are in a day? One day equals 86,400 seconds. Here is a link to a clock that has a dot for every second in the day. You can watch them change color one by one. Unless, of course, you can think a better way to use your gift of life.

Life is a gift.

We all receive this gift equally, second by second, day after day, until we die. Use this gift wisely.

This would make a nice companion to Animal Grossology: scientists at the Monterey Bay Aquarium have discovered that a major source of food at the bottom of the ocean is -- are your ready for this? -- giant balls of snot. Apparently, some surface creatures spin webs of mucous, like spider webs. These get filled with debris and sink to the bottom, where they feed bottom-dwelling creatures.

All together now: ewwwww! Ick!

The USGS, the branch of our government that reports and monitors earthquakes, reported a small earthquake in southern Florida yesterday. Well, at least that's what they thought. Residents of the Tampa, Florida area felt strong shocks and sounds of explosions last night and many thought it might have been an earthquake too. But Florida doesn't usually experience these sorts of tremors. The military later released a statement saying that two F-18 fighter jets flying low and then landing at an area Air Force base created the shocks. But, is that the whole story?
