There are plenty of folks on HN who are trying to solve climate change, myself included. But if you spend enough time in the industry, it becomes apparent that it is incredibly difficult to move the needle without significant government level intervention.

For example, no matter how hard you try, there will be no profitable carbon capture venture under our current regulatory regime. Every scheme to sell some sort of carbon capture derived chemical product will fail to compete against traditional fossil fuel produced equivalents. It is a matter of physics, not hacker spirit. The government either needs to support the carbon capture market, or regulate against the fossil fuel industry. There is no "free market" approach that works here.
