Yeah, Ben. Good morning. Thanks for joining. This is Chip. Let me answer that question. So there is kind of -- let's just talk about, the high efficiency fuel cell really supports the preferred resource business and as I said, the efficiency level is much higher. That's on track to be delivered – the first one in 2016 to become production in 2017, so that's really just a substitution kind of the broadening of the market opportunities for us which just makes us more affordable in what we are doing. On the hydrogen side and carbon capture, I will kind of take you through that. So on -- start with hydrogen. We talked about two different aspects, one is renewable and we built the first pilot plant for renewable hydrogen around for three years, that project is complete and we are ready now to deploy commercial projects with much larger size which is what I was talking about as a 10 megawatt project that we now know with confidence can get the project capital forward. So we are actively pursuing a specific project of 10 megawatts and there is others in the world to do that. So as quick as we can get those closed and then we can start to get those deployed, those will happen over the next several years. Those are pretty big projects, but they get deployed over time. On the industrial side, a similar story. We took that on as – well, this makes a lot of sense so we have the first product plant running at our Torrington, Connecticut facilities producing power, thermal energy and hydrogen. And that's running as we speak and we are talking to other people about projects at their facility, so it’s back to project development again, but again that's a commercial that as soon as we get the next contract, we can move that into revenue and backlog. On the carbon capture side, a slightly different story there. As we've laid, we did a bunch of study work for the Department of Energy and then we built a 300 kilowatt power plant for -- that's finished off its testing and things successfully. We are in the process right now of talking to multiple people, people meaning utility companies and energy companies to actually deploy and the way we are going about this is, we are looking for a project for 25 megawatt plant. It's not hard to find those kind of people, but the way that would work is, we would basically develop a project for 25 megawatts and then put into force piece of it which would be roughly 2.5 megawatts, but again that would be kind of spread out over, I would say, two years. So we are in the active mode of commercializing all those, but by the time you get the projects developed and you get the materials out there, then it's supposed to take a couple of years to pull through the revenue.
