Not really.

A lot of folks have absolutely no idea how impractical sending a completely new type of aircraft is.

The huge issue isn’t that we can’t send them, it is the training pipeline.

It takes months to years to convert pilots, maintainers, infrastructure, weapons, training programs, logistical supply, etc.

My local Air National Guard is currently in month 9 of their conversion from the F-16 to F-35 right now for instance.

It is just too long to be practical and would require planning on the conflict continuing for years for these to see combat. Sending new fighters takes away pilots from current training and combat and would hamstring the Ukrainian Air Force. It always was a dumb idea and is a good thing it isn’t happening.

This is most of the continent.

Unless you're building a new house, chances are you're going to have gas heating.

Electric heating comes with a whole bunch of other stuff that's going to be very expensive.

First you've got millions of people that can't afford to replace their gas heating unit with an electric one.

Then you've got a lot more people that can't afford to actually use electric heating as the cost is so much greater than gas.

Then you've got the problem that electric heating doesn't offer as much power as gas heating and many buildings are poorly insulated and draughty, often problems that people can't afford to fix.

Then you need to upgrade the infrastructure to handle the huge increase in electrical demand that switching over from gas will cause.

Switching from gas heating to electric heating isn't as simple as just replacing the heating unit iself, theres a whole bunch of other associated costs and work that needs performing as detailed above, which people often forget about.

And he is the duly elected president, defeating the Fujinomorista's candidate. However, Congress under Peruvian Constitution has immense power, even more so that the president, and very little check and balance against them. It's impossible to play nice with Congress who not only hates you but actively tries to remove you 3 times.

I didn't say neutrons were a specific problem : you did.

There are plenty of other engineering problems, including long duration high-temperature divertors, tungsten chemistries for wall endurance, new magnet chemistries of higher power and smaller size, computing designs to continue optimising plasma flow control especially at edges, and overall reactor design for ease of construction, maintenance, etc.

The ratio of energy in to energy out is an often ignored measure of energy production and it's eventual impact on our planet. Solar and wind might help lower CO2/CO emissions but at a great cost. The energy input to energy output ratio for wind and solar isn't good and it will unfortunately lead to massive habitat and wildlife loss as a result of needing to gobble up raw materials to produce or install enough to get the power we need. We will have to put in almost as much as we get out. With nuclear and natural gas we put in the same inputs and get 20x (or more) the return as solar or wind.

The sad thing is that solar and wind are not going to save us and will probably lead to an increase in habitat loss and destruction all over the planet. Natural gas should be used at utility scale as a bridge until we can build more nuclear power plants since they can be built so much faster.

I am a die hard environmentalist who was converted by having an open mind and just looking at the data.

Russian and Western planes are built very differently. As an example, altitude is shown in feet in Western planes, while as Russian ones use meters. Therefore for Ukrainian pilots to transfer over to F-16s, it would be a very large and wide reaching change. In the immediate term, they're better served by getting more of the kinds of planes they're used to. And there are NATO members who have old Russian planes available, so a solution exists.

>It enrages general public and unites against the west

Oh, you're right... the world is currently in a very complicated situation. While banning russian competitors enrages some of the general public (and spreading the "west is russophobic" propaganda), allowing russian competitors means Putin can take profit from these competitions as well

Wonder what can be done in this case, it's really complicated...

It’s a good question and we don’t know for sure. I think the problem for the future is the media attention this has gotten and that even if a new government gets put in place and they are very pro letting Sweden and Finland in (and so they should!), Turkey can’t just tell their people ”yeah we just let them in”. They will make out to be weak so to save face they will have to come up with something to tell their people that X discussion happened and they are happy with the outcome.

I’m not sure how many people in Turkey think Erdogan blackmailing people is bad but there is certainly enough people that has grown customary to always wanting something in return.
