It’s no secret at all that the world is facing an energy crisis. With fossil fuels prices rising, and demand growing higher than ever, people are scrambling for alternatives. Unfortunately, many of the alternatives have some major drawbacks which prevent them from being effective options at this point.
Enter concentrated solar thermal. Though its certainly not perfect yet, this technology shows some great promise for providing clean energy well into the future. Solar power is not a new idea at all, and many photo voltaic based plants (standard “solar panels”) have already been built, these plants are quite expensive due to the cost of the panel materials, and take up huge amounts of land to be effective. Even worse, as soon as the sun stops shining, the electricity stops being produced.
Solar thermal solves these problem by taking a completely different design. Rather than converting the sunlight directly to electricity, as photo voltaic panels do, solar thermal systems use some sort of reflector dish to concentrate the sunlight into a small area. This concentrated sunlight is then used to heat fluid inside an absorber tube. Think of shining a magnifying glass onto […]
