Practical Solar-Controlled Mirrors To Heat Homes


Solar Power Is Great,but there are some far cheaper ways to harness the power of the sun to do good work for us.Capturing the sun's heat with solar water heaters, for example, is a far cheaper way to reduce your electricity bills than trying to turn that power into electricity.

A new company called Practical Solar wants to take that up another step,and use simple mirrors to focus sunlight on your home,This will keep it warm in the winter. Of course,this only works for people who get direct sun in their yards,and who live in sunny but cold places.

Well your thinking how does this work





What is a heliostat and how is it used?

A heliostat is a mirror that tracks the sun. A heliostat array is a group of heliostats. Practical Solar heliostats track the sun in order to reflect its energy onto a fixed target. An array may direct the sun's energy to a common target, much smaller in size than the summed areas of the reflectors (0.74m2 reflector area per heliostat). In this case, the sun's energy is concentrated on the target. Systems that collect and concentrate solar energy are concentrating solar power ("CSP") systems.

An example of a non-concentrating application is natural lighting (a.k.a. daylighting). Heliostats can direct sunlight to areas inside buildings that would not ordinarily receive sunlight, such as through north-facing windows, or down into atriums, usually by bouncing sunlight off of a secondary reflector over the atrium. Heliostats have also been used to illuminate outdoor parks previously shadowed by surrounding buildings.

About Practical Solar

Practical Solar is dedicated to introducing solar energy products that are truly practical. Most solar energy products reduce dependence on fossil fuels and help protect the environment. However, many have not enjoyed commercial success due to relatively low energy output and high installation cost. Others have failed for lack of reliability. Practical Solar products are designed to reliably meet significant energy needs and yield a positive return on investment. Our system can be practically deployed to support energy needs of businesses, homes, farms, and other organizations large and small.



Practical Solar was founded by Bruce Rohr, CEO and President. Mr. Rohr has four decades of success in creating new technologies for the commercial marketplace. Cambridge Technology, Inc., founded by Mr. Rohr in 1980, introduced the world's most sensitive instrument for measuring contractile properties of tissues, a fluorometer with performance characteristics comparable to competitive offerings 5X the cost, and a host of other cutting-edge medical research instruments. In 1988 Mr. Rohr developed and patented a capacitance position detector, improving the repeatability of closed loop optical scanners by 1-2 orders of magnitude. This spawned a series of new products and industries for moving laser applications.


David Howell, JD, MBA, the COO of Practical Solar, joined Cambridge Technology in 1994 as General Manager. Mr. Howell succeeded Mr. Rohr as President, and the company went on to become the world market leader in closed loop optical scanners. Previously Mr. Howell started up Phoenix West Corporation, which achieved profitability in one year. Mr. Howell has over 25 years of experience in manufacturing companies. In recent years Mr. Howell as Consultant has specialized in strategic planning, profitability enhancement, and general management.

What's next? Solar powered cell phones?

This does not seem practical for places that experience snow.
