He couldn't even answer how to replace ammonia.
If ammonia can't be replaced then at least 5 billion people can't be fed.

I am beginning to believe that is the object of the hype on Covid

At least 70% of that is used for fertilizer.
I don't think you comprehend the scale of the problem.

Here's what looks to be a good article on renewable ammonia:

"Ammonia—a renewable fuel made from sun, air, and water—could power the globe without carbon"

Thanks.

There seems to be competing efforts. I like Sarb Giddey and ... the Clayton offices of CSIRO Energy's 'series of tubes'.

When he squints, he can see, maybe 30 years down the road, Australia's coast dotted with supertankers, docked at offshore rigs. But they wouldn't be filling up with oil. Seafloor powerlines would carry renewable electricity to the rigs from wind and solar farms on shore. On board, one device would use the electricity to desalinate seawater and pass the fresh water to electrolyzers to produce hydrogen. Another device would filter nitrogen from the sky. Reverse fuel cells would knit the two together into ammonia for loading on the tankers—a bounty of energy from the sun, air, and sea.

Sea-going infrastructure.

I think they mis-underestimate Australia's power potential.

So it seems like they are going to electrolysis the water for hydrogen.
Problem is that takes 237kj per mole of water. Now to convert that into knuckle dragger imperial units (mostly).
Now 237kj isn't much energy only 0.2777wh but one mole of water isn't very much water and it's almost no hydrogen, every mole of water is 2 grams of hydrogen.
So 77wh makes a pound. Now this is bare minimum theoretical power to split H2 and not actual.
The mole weight of ammonia is 17, 3 of that 17 is hydrogens.
To make the hydrogen in 170 million tons of ammonia you just need about 30 million tons of hydrogen.
It will only take about 16.6 gigawatt hours to make the hydrogen if it were 100% efficient. Realistically it will be more like 30.
It doesn't make sense to split water with solar power until all the coal and natural gas powers plants are replaced with renewable.
As of last year the United States made 66 Terra watt hours with solar, which made up about 1 and 2/3 precent of all US electrical production.
Electricity only makes up about 1/3 of the total energy we use. So solar has grown to where it can effect the rounding error in total energy use.
So the build out till we get to renewable hydrogen / ammonia is approximately never.

Focus on pollution. Reducing environmental impact will improve overall efficiency, and knock-on effects will be mitigated.

It will either get hotter or colder, best to focus on getting to the Moon and it's Lagrange points.

Actually the process of producing ammonia is fairly efficient.
I wouldn't be surprised if ammonia and all the raw hydrogen used in industry was still made from natural gas 100 years from now.
The number 1 consumer of fossil fuels is power generation by a lot.
The US military uses around 300,000 barrels of oil per day.
If most of the 20 million barrels of oil per day the US uses could be replaced with electric then the military could use their 300,000 per day just about indefinitely.
That could be further reduced by the navy going with more nuclear ships and the DoD using battery powered ground vehicles where it makes sense and the air force cutting back some flying hours.

Fuller advocated for a Design Science Revolution. One that would lift everyone instead of tearing down those on top. His example was that a king in 1900, with all his wealth, couldn't have a cell phone, if he could even imagine it. Now everyone but me has one.

The current Color revolution doesn't have adequate answers.

Consider the Oak Gall Wasp. It flies up to an Oak tree, injects it with an hormone and the tree makes it a home and start bringing food to it. That's the sort of rebelution needed.

Architecture is the container for all human's activities. Let it be natural architecture.





Indoor hydroponic farming needs less water and real estate that traditional.

Peace is breaking out all over the Middle East, due to the USofA not needing other people' oil. Fuller predicted the military shift from 'killingry' to 'livingry' (distributing medicinals).
