The best alternative technology to desalinate water is Solar technology. This is because solar desalination is a technique used to remove salt from water via a specially designed still using solar energy. This is a sustainable and environmentally friendly way to provide fresh water in many parts of the world. Here's a step-by-step explanation:

1. Solar desalination uses solar energy to heat saline water and turn it into steam.
2. The steam then condenses into fresh water, leaving the salt and other impurities behind.
3. The fresh water is then collected in a separate container for use.
4. The remaining salt and impurities are removed and disposed of.

This process does not require any fuel or electricity, making it a cost-effective and sustainable solution for water desalination.
