Horsetail
The chief medicinal property of horsetail is its high silica content. The best dietary source of silica is whole grains-meaning much of our dietary silica is lost in the refining process. In addition to silica, horsetail contains large amounts of potassium as well as aconitic acid, equiaitinee, starch and many fatty acids. Horsetail is often used for mending broken bones. Our hair, skin, nails, and bones all need silica. Silica gives our cells strength, durability, and flexibility.

Think about walking outdoors on the grass. You put a lot of weight on the little blades of grass, but they spring right back up again. This is because of the high silica content in the grass. Silica enables the blades of grass to be resilient and bend, yet not be broken. Without silica, our bones would be very brittle and break easily. The same is true of hair, skin, and nails. Without enough silica in our diet, our hair can be brittle and break easily, causing split ends.

Without enough silica, our skin loses its elasticity. Without enough silica, our nails become very brittle and split. As horsetail is very, very high in silica, it feeds our hair, skin, and nails along with our bones and keep the cells in these systems strong and resilient.

Jane Goodall, September 2011
There would be very little point in my exhausting myself and other conservationist themselves in trying to protect animals and habitats if we weren't at the same time raising young people to be better stewards.

The Sun photographed by the Atmospheric Imaging Assembly (AIA 304) of NASA's Solar Dynamics Observatory (SDO).
Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.

Solar powered electrical generation relies on heat engines and photovoltaics. Solar energy's uses are limited only by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, solar hot water, solar cooking, and high temperature process heat for industrial purposes.To harvest the solar energy, the most common way is to use solar panels.

Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
