Water in dry areas is a problem. Often these areas border the ocean which is an obvious source of water if only we could get the salt out. Renewable energy is usually available in multiple forms since arid regions usually have a plentiful supply of solar energy. Wind energy is usually plentiful where oceans and deserts meet and the ocean can provide both wave and current based power.
Understanding the market[edit | edit source]
Many people could benefit from this who live in dry areas or areas underserved by water supply systems. Disaster relief is a possible use.
Project goals[edit | edit source]
Let's start on a small scale: one desalinization plant suitable for a third world village of say 200 people (feel free to change this number if you wish.) We can scale up later. If the plant floated just offshore to take advantage of wave and/or current power that would be great as it would make the plant easily towable to where it is needed and useful for disaster relief. We want to be as ecologically friendly as possible so use of chemicals added to the water should be eliminated or at least minimized. Harm to sea life should be minimized at the water intake and waste water outflows. We also want to conform with applicable regulations.
Design[edit | edit source]
We don't want to prematurely solidify the design on one idea so let's throw out some ideas on the discussion page. Splitting into several alternative designs is okay too.
Discussion[edit | edit source]
Cleaning water of other unwanted substances is also possible. We don't want to remove minerals/or other good stuff unless absolutely necessary but we do want to remove anything toxic. Since solar powered distillation is the obvious solution, perhaps minerals could be added to drinking water after distillation.
Next steps[edit | edit source]
Let's make some design suggestions.
Conclusions[edit | edit source]
It is early times: no conclusions yet.
