 Green Heat is a company that produces a product called Transparent Insulation. What we have here, this glass actually can radiate heat. Most heat in your house actually, you lose it through your windows. For example, if it's 70 degrees inside your house, and it's 30 degrees outside your house, the heat wants to move from inside to outside. However, if you actually heat your window to just slightly above room temperature, to say 72 degrees, and it's 70 degrees inside, at that point you create a thermal barrier. And you're actually then keeping all of the heat that's in here into your room. Hence, you have transparent insulation, and that's what we're pretty excited about. Now besides that, besides this idea of heated glass, this is an energy-performing window. So you get all the benefits of having a high-performance window. So in the summertime, all you do is turn it off, and you have an energy-efficient window. And in the wintertime, you just turn it on. So it's pretty that simple. From a cost perspective, the window is about 20% more than a standard conventional window. But the benefits are it's going to save you a lot of money. Looking at a payback in about a three-year payback, as well as it's going to be more comfortable. Because like for example, in the wintertime, who wants to stand by the window when it's cold? You don't, but when the glass is heated, you actually want to be next to it because it's more comfortable. I guess we're proud of this. It's especially good for people interested in achieving net zero. By using this technology, when the glass is turned on, it's the next best thing to an actual wall. That's why we call it thermal insulation. It's as close to 100% efficient as you're going to get with glass. Transparent insulation, the way of the future.
