Science Daily provides an interesting article on an invention created by Rich Diver that may soon make parabolic troughs (one of the most popular and widely used solar collectors) more affordable and energy efficient.
Diver’s new theoretical overlay photographic (TOP) technology is drawing interest from the solar industry because of its simplicity and the need to find solutions for global warming.
Once used almost exclusively in space, photovoltaics are used more and more in less exotic ways. They could even power your house.
Scott Aldous explains step-by-step how solar cells convert the sun’s light into sustainable electricity for daily living.
Water heating is a major energy consumer. Although the energy consumed daily is often less than for air conditioning or heating, it is required year round, making it a good application of solar energy.
Use the solar water heating calculator to determine if using solar energy for your hot water needs is beneficial.
We are confronted every day by the notions of energy and power: cars and motors are sold by horsepower, light bulbs by watts, natural gas by therms, electricity by kilowatt-hours, and air conditioners by tons or BTUs per hour. Is energy the same as power? If not, what’s the difference, and how do all of these units relate to each other?
Use this interactive calculator to simply find out how energy is measured, consumed, and used.
Learn how a solar cell works. From the ‘Anatomy of a Solar Cell’ to the ‘Generating Electricity’ this PBS NOVA program demonstrates how the photoelectric effect works and how solar cells can transform light into electricity.
