The Nightshade ( Solanaceae) family is a very common family consisting of mostly herbs with fuzzy leaves and colorless juice that is also very rich in alkaloids. Their flowers are typically bisexual with usually 5 united sepals and 5 united petals, also usually consisting of 5 stamen and 2 chambered ovary. There are approximately 2,300 different species of plants in the Nightshade family including tomatoes, potatoes, eggplant and peppers. Some nightshade plants also have narcotic alkaloids; some of them are addictive like nicotine made from tobacco. Most of these plants that contain narcotic alkaloids are useful for numbing the sense of pain in your body. Another substance that can be extracted from many nightshade plants is scopolamine which can be used to treat seasickness or vertigo. - Prepared by CJ

Solar Energy Explained

Image
Solar energy is one of the key parts in the movement against global warming. If we can power things with it, we can end the use of gas and oil. There are two main ways of producing energy from sunlight: Concentrated Solar Thermal Power (CST) and Photovoltaic Power (PV). CST uses mirrors to concentrate sunlight onto a pipe containing water or a synthetic oil called Therminol. It then heats the water or Therminol to several hundred degrees. After the liquid is pumped through the complex system, a heat exchanger uses the energy to create steam, which powers an electricity-generating turbine. The second way of producing solar energy is by using Photovoltaic power. “PV”,  makes electricity directly, without using a turbine. The semiconducting silicon panels, when hit by sunlight, uses the photons in the sunlight to to release the electrons from the atoms in the photovoltaic material so they can come out of the solar cell as an electrical current. To convert the direct current into...
