Natural water filtration system using Tidal Energy
Simply stated, islands should take advantage of the surrounding sea water close proximity to develop your water supply. If you buy the "technology" it will be very very expensive. If you make it, many will benefit and it will be cheap. People build expensive equipment that are difficult to copy. My solutions is very simple and easy to copy and reproduce. In effect, it is a DIY solution.
Medicines that are manufactured are expensive. Herbs and plants are all around us and free if we produce or make them ourselves. We just need to take care of these plants and herbs.
Conventional design of water filters (Reverse Osmosis) are using pumps and purchased filters. Electricity will be bought to run the pumps and from the energy of the pump will create the clean water pushed out of the filters. Instead of using a pump we use the power of the moon causing tidal changes to move the water and clean it. Very simple, but there is no money in manufacturing this and people will not invest on this because people will copy it easily. Just like manufacturing drugs. - There is no money in teaching people how to plant herbs and medicinal plants.
Can you imagine if we had 10 Billion Php and produce this "filter box" and that we can already have our FREE water for the whole country???
