By locomotive. Seriously, if you're not building indoor farms around a rail depot, you're doing it wrong.
Our current methods are not recycling nearly enough phosphorus, for that matter.
I have ideas about pretty much any topic you can name. How about firearms?
Look at that Textron prototype. It has a moving chamber that acts as a lifter for the Cased Telescoped cartridge. That is even more concentrated autism than I could ever manage myself. Jesus. Imagine field-stripping and cleaning that thing.
I have a better idea. Why not have a conventional bullpup 5.56mm rifle with a nice 19 to 21" barrel, a servo-operated sear and adjustable electronic trigger to get rid of that bullpup grittiness, and a TrackingPoint-style ballistic computer with grid-finder capabilities?
Because, at this point, with the technology that we currently have, there is absolutely no reason why each and every infantryman can't also be a forward observer.
Almost all the tech needed for a surprisingly accurate grid-finder can be found in the average smartphone. GPS, accelerometer, and gyro. All you need is a rangefinder to pinpoint something, and the device needs to know its own position and orientation. That tech can be squeezed into a rifle scope these days, easy enough. With one of those TrackingPoint scopes, literally all you need to make it a grid-finder is to add a few more chips and some software changes to the damn thing:
Aim at some guy, touch one button, and every F-35 and 155mm gun in the area knows where he is. Nice and simple. No need to mark the target with smoke. No need to fiddle around with a DAGR and waste time figuring out the bearing and distance to the target. Just one little button press, and that fucker is marked for death.
But no, instead, the military wants to buy a ridiculous piece of clockwork like this:
The shit I keep seeing the Army looking to buy, it just looks plain exceptional.
After a few of my lectures, all of their secrets would belong to Uncle Sam.
