Global Climate Change
The Convective Heat Engine (CHE) is the primary infrastructure for a sustainable city design which can protect against drought, famine, and climate change. It can be used to capture thousands of tons of carbon per year while providing a reliable supply of water, shelter, and electricity for a population of 100,000 people.
The latest estimated price of a CHE is $6 billion. The price tag per ton of carbon being sequestered looks expensive at first glance. But the CHE is first and foremost a new infrastructure technology for sustainable city designs. The net negative carbon emissions are merely a byproduct.
When we properly view the CHE as infrastructure we can begin to see that a population of 100,000 people could invest $60,000 into a sustainable and reliable home.
