Descripción

The sun is the ultimate renewable energy source that pours out unimaginable amounts of energy. Most of the sun"™s energy is emitted as visible light. To harness the sun as a source of energy, it must be converted from visible light into either heat or electricity. Visible light can be converted directly to electricity by utilizing a technology referred to as the photovoltaic effect. Photovoltaic devices are constructed by layering special materials called semiconductors into thin, flat sandwiches called solar cells. When sunlight strikes a solar cell, electrons naturally travel from one layer to the other through connecting wires because of the different properties of the two silicon wafers. This project is a wonderful demonstration of clean, green solar power and is based on BEAM technology. When the solar cell is exposed to sun or any bright light source, the pendulum will start to swing, almost magically. Each time the pendulum passes the bottom of its swing, a hidden coil will give the pendulum a little nudge using stored electricity generated by the solar cell. This secret nudge keeps the pendulum in perpetual motion as long as there is enough light! This cool KITwas inspired by the Magbot Pendulum project in Dave Hrynkiw's book titled: Junkbots, Bugbots & Bots on Wheels. The Solar Pendulum makes a great science project or an interesting desktop accessory. This high-tech device is a unique toy and a learning tool all in one.
