1. What is WaterLight Technology? Does it really generate electricity just by adding water?

Yes, WaterLight Technology uses electrochemical technology to generate electricity by simply adding water. When saltwater is introduced into the device, it activates a chemical reaction between the aluminum anode and the oxygen in the air cathode. This reaction produces aluminum hydroxide and electricity within seconds.

This process is similar to zinc-air batteries but uses aluminum due to its higher energy density and availability. WaterLight devices work with various electrolytes, including table salt (NaCl), seawater, potassium hydroxide (KOH), or sodium hydroxide (NaOH). It’s a clean, safe, and environmentally friendly way to produce electricity, ideal for off-grid, emergency, and rural applications.

2. What types of water or liquids can I use to power it? Does it need distilled water?

No, distilled water is not necessary. WaterLight is designed to be versatile:

• You can use river water, pond water, stream water, seawater, and even urine or tea.
  
  

• In areas without clean water sources, many common liquids such as juice, milk, soft drinks, or sports drinks can serve as the activating medium.
  
  

• Electricity is generated within 10 seconds, regardless of the liquid.
  
  

• While all liquids can activate the battery, salt-containing solutions (1–10% salinity) offer optimal performance.
  
  

3. Does the salt concentration affect how long the lamp or generator runs?

Yes. The salt concentration directly affects the reaction speed and duration:

• Higher concentrations result in faster reactions and shorter usage time.
  
  

• A concentration of 1–10% salt is recommended.
  
  

• Seawater, with ~3.5% salinity, works well but may benefit from added salt for better output.
  
  

• You can also use sports drinks or salty condiments like soy sauce if they meet the minimum salt requirement.
  
  

• Very high salt concentrations are not harmful but are wasteful and do not increase performance beyond a certain point.
  
  

4. Is there a difference in power output between using regular saltwater and a specialized electrolyte?

Yes. While household or industrial saltwater can be used, our proprietary electrolyte powder (such as KOH) significantly improves the voltage and duration of power output. For users seeking higher performance, especially in large-capacity units, we recommend using the factory-provided electrolyte.

5. Where can I buy the electrolyte powder?

You can purchase the electrolyte powder (e.g., potassium hydroxide) from:

• Local chemical suppliers
  
  

• Authorized WaterLight distributors
  
  

• Online through our website (Coming soon)
  
  

6. How does the price compare to diesel generators, gas-powered engines, or solar + battery systems?

WaterLight generators are tailored for emergency and off-grid use cases where traditional power sources are unavailable or unreliable. While the initial cost may be higher than basic diesel or gas generators and solar kits, WaterLight offers:

• Zero emissions
  
  

• No flammable fuel
  
  

• Long shelf life
  
  

• Fast activation
  
  

• Low maintenance
  
  

It is not intended to replace full-scale solar systems, but rather complements them in crisis or mobile scenarios.

Custom models can be developed based on client needs and deployment environments.

8. How does electricity generation work, and what is the white residue left behind?

The WaterLight aluminum-air system works by oxidizing aluminum in the presence of water and oxygen:

• At the anode:
  4Al + 12H₂O → 4Al(OH)₃ + 12H⁺ + 12e⁻
  
  

• At the cathode:
  3O₂ + 12H⁺ + 12e⁻ → 6H₂O
  
  

• Overall Reaction:
  4Al + 3O₂ + 6H₂O → 4Al(OH)₃
  
  

This produces electricity and aluminum hydroxide (Al(OH)₃), a white, non-toxic flocculent residue. This byproduct can be safely disposed of and is not harmful to the environment. In some side reactions, hydrogen gas may be released in small amounts.
