Once there were chariots, and it was reckoned by some that the Sun was pulled around in one. Using a 1 volt x 500 mAmp solar panel and a 50-tooth driven gear, this unique uni-axle Solar Chariot relies on the weight of the motor to keep the panel facing up. Easily assembled, with CD's for wheels. Customize with [...]
SunWind solar panels are made with polycrystalline solar cells mounted to a firm substrate with clear epoxy encapsulation. They are marked for polarity and come with rugged 15 cm (6") alligator clip test leads attached, allowing for active experimentation. SunWind supplies three sizes of solar photovoltaic panels: 1.0 volt, 1.5 volt, and 2.0 volt. All [...]
Galaxies spin, solar systems spin, planets spin...and the electrons making up everything around us are spinning. From the largest to the smallest, Spin is how Universe works. By studying these educational artifacts, you too will become wiser in the ways of the workings of the Universe. Just as Newton grasped that our moon and an [...]
While working on the instructions for the new renewable energy kit we have in prototype, found this old photo of a young girl playing with a very early version, at an EarthFest we held in Comox, BC about 14 years ago. Renewable energy child.
A new Website which allows you to select your closeness and field of view, and step through Sun images second by second or day by day, capturing screenshots or making movies on the way... http://helioviewer.org
One of the great unsung books of our times, Cosmography, by Buckminster Fuller, is the last book Bucky worked on. The manuscript was neatly stacked in the middle of his desk when he died, and was worked on for a further 8 years by his adjuvant, Kiyoshi Kuromiya, before finally being published in 1992 (Macmillan). [...]
Ernie Wirtanen was an early benefactor - he helped me get the initial grant to create a renewable energy kit for elementary schools back in 1994, writing a letter from the "business community" to the Science Alberta Foundation - and promised to help me in its early development, enticing me out onto the branch of [...]
This is a charming example, in 12 frames, of the relative intensity of solar energy received by the Northern hemisphere during our planet's annual tilted spinning trip around the Sun...taken in a single day in the Arctic, by Anda Bereezky, in 2005. The I Ching, one of the Chinese Classics, attributes a "hexagram" to each [...]
