I'll do my best to answer the question. I don't have the exact numbers.
We have put in excess of $10 million into developing the technology. It's not solely for the Alberta site. We've done smaller pilots leading to that larger site because our partners wouldn't be interested in something that's completely unproven.
We've received a small amount of funds from investors in the past, but being a materials technology, we also deploy our materials in medical devices and are fortunate to have revenue that comes from that medical device. This medical device is a dental device. All the revenue we generate from fixing people's teeth we funnel to our clean tech application.
I'd say that about 60% to 70% of it is funded through investors as well as revenue generated from other opportunities so that we can scale our technology.
