If you're using outside air to separate (you'd kinda have to), then you only have to outflow the 20% that represents the oxygen that you "generate". The nitrogen gets dumped overboard. Of course if you do this you're also dumping some of your freshly generated oxygen too. Then there are the CO2 scrubbers that have to be maintained or replaced regularly. Imagine the average shade-tree experimental owner diligently replacing scrubbers.

I suppose in the context of aviation, we all pose some risk to others. If you mean that he's a risk to those who might actually buy something he designs, well, that seems more like Darwin at work to me.

Great minds

Airplane is a pretty loose definition in the experimental world.
It flew.

I have found the community to be surprisingly concerned with safety and engineering. The types that would endeavor to built their own airplane for no reason other than the enjoyment of it tend to be pretty smart guys. An average Vans (or even Zenith) is probably better engineered and built, given modern tools and FEA/CFD, than older certified designs. I would feel safer in an average homebuilt RV than in a 60+ year old Beechcraft developed on a drafting board and certified under CAR part 3.

I'm sure there are some nutcases in there too, but they seem to be the minority, and being a nutcase makes your chance of actually completing an airplane slim, and selling one even smaller.

I have no concerns Peter is going to be successful and sell someone a kit that actually gets completed and signed off – just not going to happen.

Based on recent events, a significant fraction of the population has similar problems when it comes to understanding epidemiology.

Peter is not some harmless and amusing village idiot, he is dangerous not only to himself but potentially to others.

Ask the corn.

And that wasn't the first time he had trouble in the air.

You're a brave man to post that, even in green. Does your wife read BT?
