Here to go with the earlier notes on our upcoming field trip to CAT are a series of photos I took on previous trips. (The ones in the previous posts belong to CAT)

From top to bottom: Professors Womersley and Phillippi get recycled.
The wind tunnel demonstrator with wind turbine "gloves": discover the principles of "lift."
One of several hydro-power demonstrators, this one with a cut-away window to see the Pelton wheel working (while still producing electricity).
A solar panel with attached voltmeter on gimbals: rotate towards sun to get the best power supply. Solar panels do best with full, direct sunlight.
A retured wind turbine blade with chronology of wind power. Humans have used wind power for hundreds of years.
Another solar power display: This one has big "clouds" to use so you can see the power loss from dappled sunlight.
The Eco-Cabins, where we'll stay.
An ancient remnant forest in Wales, of oak. Welsh and other UK native woodlands are similar in species and species composition to New England, part of the same biome, another northern temperate hardwood forest. But deforestation has reduced woodlands to a fraction of what they were in the UK, while here in Maine our woodlands are expanding.
