Okay, so with respect to Heliogen right, I think the question that was asked was those land purchase what can you do into renewable capacity, so look for Heliogen, their core value proposition was using their new technology, they can concentrate solar heat a lot more effectively, lot more efficiently with very low capital and raise the temperature of the steam to very high levels, right. And when they're able to do that, the amount of renewable electricity needed to break the hydrogen becomes a lot less, and therefore hydrogen are the less expensive, that's number one. Number two is, with that high temperature steam that you raise and what you do with the heat, you can run that entire hydrogen factory for much longer, rather than just when the sun shines under intermittent fashion, and keep the rest of your factory idle thereby the capital not giving the efficiency it needs to give. So it's a win-win. We are completely aligned with that thought process of combining solar concentrated heat, and solar produced electricity to make the greenest of green hydrogen, at the lowest of green in terms of dollars. Okay, so we are completely aligned with that, in terms of what capacity we can provide, here is what you need to know, right? A gigawatt of Bloom factory, which is what we will have at the end of next year, you're seeing the capacity is the equivalent of 2.4 gigawatts of electrolyzers. And we can fungibly make one or the other. That's number one. The number two is, you've been hearing me say since we started the company about we have designed our factories, to be capital efficient, and to be able to stand them up in a year. If you just went on faith, you no longer need to go on faith because the Fremont factory, we are just demonstrating that, one year to build, one year to recoup your money. So if you want 2.4 gigawatts worth of electrolyzers for 2024 as long as you're willing to sign up for the purchase order, I will have the factory and deliver those products to you. Right, so we are ready. And we are itching to go.
