Re: The Climate, Environment and Energy Thread

You are confusing an engineering / science issue with an issue of politics, economic and law.
If climate change is a genuine issue, then why do the percentage efficiencies matter to you so much you oppose all better technologies, an emission cut is an emission cut isn't it?
What is the obsession with backing one solution?
btw., The latest science from those institutes you like to quote has an updated version of climate change, why aren't you quoting that, is it because they are saying your SolarPV is no longer enough? Cornell, Harvard, Oxford, Cambridge, they recently started sprouting a need for nuclear(fusion or fission), because they now claim emissions must be negative, in fact they have put negative emissions policies in place for their own operations..
Business, especially big business, doesn't just setup and do what it likes, it has to be issued licences and permits. The example I gave about ethanol shows just how restrictive and myopic bureaucracy can be, even when there are immediate solutions to massively reduce a waste the bureaucracy opts for the status quo under pressure from a minority that spreads fear.
You can look over there if you want, we all can, but it's just more of the same!
Why is that minority spreading fear, the major opposition to many projects is not generated because they are infeasible, but fundamentally because they are a feasible alternative to something else, because it's fundamentally a battle for fund$ not a battle of technology.
The renewables sector needs politicians to keep thinking there are no alternatives or else the subsidies will dry up and the true cost of renewables will be exposed to the general public slowing uptake. They are frantic to find a non-rare earth alternative to continue SolarPV uptake, because if they fail they know the politicians will turn to technologies they fear like hydrogen and nuclear. But institutes like Harvard and Cornell are starting to question the viability of SolarPV, simply because of resource issues, it turns out that if you really do the sums on what is required to SolarPV to 80% market saturation there simply isn't enough rare materials easily accessible in the earth crust to do it at a viable cost level.
Some engineers and scientists are even touting nuclear connected to desalination plants as a alternative source, producing many of the rare materials as a by-products. To most involved in the industry this is a der Fred moment, but it would be political poison for the industry if it came out and stated it has a dependency of nuclear to reach it's targets. You will even find half-baked ideas to autonomously mine the seabed for mineral precipitates, this is primarily to meet a demand driven by SolarPV and Wind turbine production, worrying about the damage some existing imperfect process causes seems fairly trivial, and opposing improvements in those process is outright sponsoring environmental vandalism! 
I was involved in a project a few years ago that developed some new materials processing techniques, that were designed to be sustainable from the ground up. The process eliminated every type of industrial waste from a certain industrial process, was cheaper to run, and made zero use of rare resources. Yet it failed, not because it didn't work, but because in the EU political funds to oppose change were almost 1000% higher than those allocated for the development of technology. It failed because lawyers made themselves richer out of opposing change than adopting it, leeching off a EU$120M annual fighting fund designed to "preserve EU jobs" in Eastern block countries. It seems that even in the woke EU pollution is OK as long as it is NIMBY, the same as here it seems.
Just like with COVID, when the moment there were viable treatments or vaccines available, the politicians blinked and the government funding dried up, the public had to pay directly. The same might happen to SolarPV, and that is the founding fear of much of the opposition to all the other solutions.
