Mary Shelley's book Frankenstein was published this day in 1818. It detailed how a mad scientist powered up his do-it-yourself project with free electricity brought down from the roof. Wish you had a way to produce electricity for workshop projects and to run your household? Are your electric bills going through the roof? A solution just may be up there too! New solar tiles look like ordinary roofing and blend in with most popular styles, but they are also photovoltaic collectors that convert sunlight into electricity. The electricity it creates then becomes accessible household power. A typical ?energy roof? uses 300 square feet and covers approximately a 17x17? area. In a sunny climate, it produces many thousands of kilowatts of clean energy per year. Any excess power you have can be fed back into the utility company grid for a credit on your bill!
