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.
Determine the cost inputs and energy outputs of small scale ethanol production from local and conventional sources.
Sustainable energy is the provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Sustainable energy sources are most often regarded as including all renewable energy sources, such as hydroelectricity, solar energy and power, wind power, wave power, geothermal energy and power, biomass fuel and energy, and tidal power. It usually also includes technologies that improve energy efficiency. While many renewable energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development. As of 2011, small solar photovoltaic (PV) systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves. |
