Yes, there are many of those. I'll just name one or two.
We were capturing CO2 from generators to reduce the amount of CO2 in the atmosphere. We need to filter out all the soot, as it has an impact on people living in it and an impact on the ice. We have also developed new technologies, such as a micronuclear reactor that would fit the bill and provide resources and energy in the north at very low cost and with very high environmental capabilities.
There are many of those. I still work on different projects in the north to generate better environmental quality.
One of them is very interesting, because the Arctic is a desert to a certain extent. There's not that much clean water available, so we have developed a technique that uses nanotechnology to extract water from the atmosphere at a very low cost, therefore providing a lot of needed materials and consumables people require to live.
