There's nothing dodgy about climate science. It's conclusions don't suit 
the fossil carbon extraction industry which has a lot of money, some of 
which it spends on climate change denial propaganda

Anthropogenic global warming isn't any kind of delusion. If John Larkin 
had ever learned much about science he'd be aware if this.

There's no need for fear, depression or despair about anthropogenic 
global warming. We finally seem to have got to the point where CO2 
emissions have peaked. We still have to get to the point where they get 
done to the point where the CO2 level in the atmosphere can start to 
fall, but at least it is in sight.

One nice thing about renewable energy is that solar cells and wind 
turbines come in small modules. You can put them where you need energy.

You can couple them together into larger grids, and get some advantage 
from doing it, but renewable energy doesn't offer authoritarian regimes 
any kind of political advantage (which may be be one of the reasons so 
many people are lying about it).

There isn't any fear or hysteria around (except perhaps in the fossil 
carbon extraction industry, as they look forward to rapidly diminishing 
cash flows).

Your kids don't seem to be as enumerate as you are.

"Lunatic greenies" who don't want to breed seem to be one of the more 
implausible inventions of the climate change denial propaganda machine.
John Larkin is a gullible twit, and he is convinced that they exist.
I've never met one.

Not good advice.

is a full bottle on active low pass filters. They do cover the Sallen 
and Keys configuration, and a lot of variations. I like the one with a 
little bit of gain that lets me use equal value capacitors.

It your "mild" variant one they didn't cover?
