Solar thermal Flywheel

Wheel.jpg - 71090 Bytes

This is the way it used to be done, a steam engine fires with the stored energy of the sun when oak trees, coal, crude oil are burned.

This steam engine sits in Holland, Michigan on display. It ran the Baker furniture factory from 1905 to 1959. It generated 350 hp, is 15' 3" in diameter and weighs 16,400 lbs.

There is an old kid back on the block------Solar thermal energy can be used to heat and cool your home.

The Solar Thermal Flywheel Home

This glyph illustrates the fundamental thermal paths to follow when you begin your new solar home plans.

A solar collector array converts the sun's electromagnetic radiation into the infrared. This energy is "heat exchanged" and stored in water, the perfect storage medium.

The idea here is to "collect" soalr energy, especially in the summer months, stored in a very large water tank. Just as the steam engine ( shown above )stored fossil fueled energy in the inertial motion of the very large wheel.
