I keep praying for a miracle wake-up call that will inspire our leaders to negotiate an agreement that is profitable for the "too-big-to-fail" firms of our RULING CLASS, those major shareholders and highly paid executives, acceptable and effective enough to solve our pollution problems -- including climate change aggravated by pollution, as it is for our poor working class to survive with.
We have all the technology we really need, at least on a working prototype level, so it is all, technically, at least, feasible. Some of it still needs some work to make it economically feasible. When Algae Systems, for example, managed to make air-droppable kits for growing algae for oil in clear plastic bags, which could be hung up to sun and produce liquid fuel for less than the $100/gallon it cost to transport diesel over vulnerable supply lines, they eventually got it down to not-quite $27/gallon.
Then Algae Systems switched to figuring out how to compete with petroleum products for the civilian market. Last I heard, there was $10/gallon algal bio-diesel, which was practically almost cost-competitive for expensive-to-ship-to islands like Puerto Rico and Hawaii. Now Sun Fuel has made an add-on for the US Navy's big nuclear power battle-ships to make synthetic diesel with carbon from CO2 dissolved in seawater and hydrogen electrolyzed from seawater for $6/gallon; this was better than $8/gallon to ship diesel.
Joule Unlimited has patented GE microbes to make ethanol, gasoline, diesel, and jet fuel (aka kerosene), which they hope to get down to $1.20/gallon.
