Convenient Power That Helps You Save Money and Protect the Environment
The Sunforce 50048 60-Watt Solar Charging Kit lets you harness the power of the sun, the most powerful and plentiful source of energy available to us. This inexhaustible supply of power is freely available wherever the sun shines, and gives users the freedom to power their homes, RVs, boats, batteries, and electronic equipment far from civilization or right in town. Solar power can help cut your energy bills by reducing your dependence on the main electrical grid, and can also provide back-up power during outages. Unlike nuclear and fossil fuels, solar power systems are clean and pollution-free, and they require very little maintenance to operate.

Sunforce Solar Panels are effective in areas of both high and lower
sun exposure, making them ideal for use in the United States.

About Amorphous Solar Power
Amorphous solar panels are created by spraying silicon on to glass in very thin layers, and are commonly known as thin film solar panels. This process allows them to be better at generating electricity in all lighting conditions, including cloudy or shady environments. Sunforce amorphous solar panels are weatherproof and suitable for outdoor use. They have a maximum operating temperature range of -40 to 176-degrees Fahrenheit, require virtually no maintenance, and are also effective on cloudy days. They can even withstand impacts from one-inch hailstones at 50 miles-per-hour.

Solar panels convert sunlight into an electric current, they do not store power. Sunforce Solar Charging Kits are primarily used to recharge 12-Volt batteries (not included), which store and provide usable power. The included 200-Watt power inverter allows you to use traditional 110-Volt appliances with this system. The included Sunforce 7-Amp Solar Charge Controller must be installed to prevent any connected batteries from overcharging. Once fully charged, it is normal for the charge controller LED to turn off and on as the battery voltage fluctuates from the discharge/recharge cycle.

Addressing the sustainable energy crisis in an objective manner, this enlightening book analyzes the relevant numbers and organizes a plan for change on both a personal level and an international scale—for Europe, the United States, and the world. In case study format, this informative reference answers questions surrounding nuclear energy, the potential of sustainable fossil fuels, and the possibilities of sharing renewable power with foreign countries. While underlining the difficulty of minimizing consumption, the tone remains positive as it debunks misinformation and clearly explains the calculations of expenditure per person to encourage people to make individual changes that will benefit the world at large.

In the 20th century, cheap and abundant energy brought previously unimaginable advances in health, wealth, and technology, and fed an explosion in population and consumption. But this growth came at an incredible cost. Climate change, peak oil, freshwater depletion, species extinction, and a host of economic and social problems now challenge us as never before. The Post Carbon Reader features articles by some of the world’s most provocative thinkers on the key drivers shaping this new century, from renewable energy and urban agriculture to social justice and systems resilience. This unprecedented collection takes a hard-nosed look at the interconnected threats of our global sustainability quandary–as well as the most promising responses. The Post Carbon Reader is a valuable resource for policymakers, college classrooms, and concerned citizens.

Build wind-powered generators to energize your electric vehicles and charge your rechargeable batteries! The wind spins the turbine, which turns an electric generator, which in turn charges your rechargeable AA batteries (not included). You can then use those wind-charged batteries to power the model vehicles you build. The six models include a glider, sail car, jet car, tractor, racecar, and tricycle.
This kit includes two styles of wind turbine blades and a gearbox with three different gear ratios for experimenting. You can adjust the angle and number of wind turbine blades to make best use of wind, to make the LED light up brightly, and to charge the rechargeable battery as fast as possible. Explore this amazing, free source of renewable energy and store the electricity you generate for use in practical applications!
This kit includes a 40-page color instruction book with illustrated step-by-step instructions for assembling two windmills and six model vehicles, and conducting various experiments.

Original Caption: John Bayliss, president of the Solaron Corporation, the first publicly owned solar energy company in the nation. The firm used a hot air heating system comprised of flat black aluminum plates behind double glass panels. An insulated bin filled with rocks two inches in diameter is the heat storage system. It is designed for the basement of the average home while the collector panels are fitted to the roof. The corporation is now manufacturing the solar heating and storage system for the mass market, 05/1975.
