Thank you for the question.
I can give you a simple example. As a house owner, I have a gas bill that comes to approximately $1,800 to $2,000 a year. This is the cost of natural gas delivered to our property. If we eliminate that, this is the number one saving. The homeowner would put zero dollars toward the fuel. Our fuel is water. The cost of having water on our property is very minimal compared with other fuels. There are also savings that will come from not producing any greenhouse gas emissions, so the pollution is zero. That's another saving.
Regarding the return on investment, if we take an example of saving approximately $1,800 a year for five years, that's a saving of around $6,000. Basically, the cost of our unit is within this range.
I will leave the cost and the details to Mr. Fairfull. He can elaborate more on that. I will leave him to answer more about the question of the cost of our technology.
