Math fix - assembly machine works 25% faster than assumed, saving energy and driving up the efficiency by a few more percent.

The "B" signal is not even necessary. An even simpler way to make it is: "A > 0; Output A = 1" (and feed it back to itself). This one is toggled on with any positive "A" (of any length), and toggled off with any negative "A".
A great use for this is to have a persistent Charging/Discharging ...

I had some time on a long car trip and made a spreadsheet to do some figuring for an optimal way to boost chemical energy storage.
After I got some interesting numbers out, I was able to wrangle them into an over-unity device. (Sadly not a perpetual motion machine since it can't use the rocket fuel ...

Is it possible to mirror (not rotate) the fluid inputs/outputs on chemical plants?
They always seem to be on the most inconvenient side and I haven't been trained to subconsciously lay out my base in the ideal manner yet.

If it is smart enough to take either input from either pipe and I simply ...

I did see those.
I'll play around with the train parts first, but if I can't figure out why it isn't working, then I'll hit those tutorials.

Ok, I've got another thing :D
I only discovered the blueprints button after launching my first rocket.
I'd scoured the tech tree looking for blueprints, possibly relating to the robots, and given up to assume it was a mod thing.

Only now I found the button that means I've had them all along when I ...

The biggest thing IMO: The demo should be updated to a more recent build.

My initial contact was through youtube videos.
I was playing around with the demo and trying to tweak graphics settings to get it to run well without the terrain and random textures vanishing.
Tweaked enough to play the demo ...

You are probably all aware that even a basic base soon requires underground belts to get items from Point A to Point B as the number of factory links becomes non-trivial.

I've been playing the demo while trying to find settings that allow my potato of a video card to successfully render everything ...
