You haven't even thought about the water aspect. You think it will be bad when the A/C goes out? We're gonna be out of enough potable water to sustain the population right around 9 billion people. The change in infrastructure is really required to use the waste heat from all our power generation which we currently throw away to distill water. Once you have it distiller and you have an electric plant right there already, rather than throttle it up and down losing efficiency and opportunity to grid demand and lack of, you can take all the off peak time, stay running full efficiency, and store the electricity and water for shipping and demand use. We'll triple the sellable output of our current infrastructure as well as add water to the product list, hot water at that.
The next big war will be over water, and billions will die in it because they will have to because the earth can only support the resource demands of a billion without help. We do well at agriculture however agriculture uses a lot of water. We are doing very little about the problems of the reduction of useful water for irrigation on a global scale. Aquifers are going down, drought cycles are spreading further and lasting longer. The key to being able to produce food is to provide water.
We could avoid all this, we have the technology, we have the resources. We have deemed it not worthwhile because it is not as profitable as maintaining status quo. How will you trade your money for food when there is no food?
