Sustainability is like you know they're saying that you know think globally act locally so sustainability starts from your morning coffee cup. For example let's say hand sanitizer right a typical hand Sanitizer is about 70% isopropyl alcohol 30% water now the waste water from the handSanitizer is 7%. We can mix it with solvent and we burn it to produce carbon dioxide. That's the kind of thinking we need at grassroot. I am shocked how much we've talked about nuclear energy here because it doesn't come up a lot everybody's solar. So come on in on this conversation.
