 We really were trying to design a house that uses all its own energy first and then if that's not enough it draws from the grid. Right now we are pretty darn grid independent. People they build these monuments with their wealth and what we want to do here is build a monument for what's possible in a Greek building. We're going to see more and more people having renewable energy and battery storage together and knowing that they can be independent of the grid. They don't need to have the grid to power their home. I'm a progressive cowboy. A lot of people talk about freedom. You know are you free when a company has the ability to cut your power off when you're trying to take care of your family and just live your life. I just wanted to build as green a house as we could come up with. We felt it was possible and this is a fantastic model. It can be done. It could be done on a large scale and all you do is scale it back and you can do it. The challenge along the way was to bring in these technologies and it kind of snowballed a little bit like how about doing this and how about doing that. Okay and what's the best way, who's the expert knows how to do that. With our dual access solar trackers we're extending the solar day out to a very long period of time. Typically it's about five hours for a solar day with ground mounted solar trackers and we can get up to nine hours a day. It's remarkable with the tracker technology how much we're able to gather. Dual access trackers means you're tracking exactly where that sun is across the sky both vertically and horizontally and when you add it all up it's 40% more than if you had a stationary amount PV panels. These strong well built German trackers can go up to 75 miles an hour before they actually go to a horizontal and shut down so that they're not destroyed by the winds. It's like this beautiful piece of art that is very functional and productive and clean. That's going to generate enough to take care of all the lighting needs of the house. So this particular one is called a vertical access so when it turns it actually looks like a solid cylinder. The birds actually see it. We didn't want to be chopping up the eagles. Right now those batteries are for electrical outages when the grid goes down which happens a lot out in this area. What we'd like to do is to be able to be off the grid for three or four days if we have no sun. Eventually with some lithium ion batteries like Tesla's developing we'll turn off the grid altogether. We came up with the idea midway through the project of utilizing rainwater to provide the domestic water supply here. It sounds like a lot of water but it's not that much. When people shower and do everything they do in their daily lives they can use water pretty quickly. We became the first property of its kind to have a black water treatment system in San Diego County. We've put a lot into this quote unquote case study home. There's a lot of it that I see being the homes of the future. I like to think of the term the high hanging fruit the low hanging fruit. The low hanging fruit are things that are easy to do are not expensive to do that can make your house much more energy efficient.
