- Fence-powered heater
	- Run fence at 120v straight off the line
	- Run fence at a constant, elevated voltage
	> 1e-7 ohm-meters of resistance for steel, 
	> 3mm steel diameter
	> R = rho x L/A
	> `1e-7 ohm-meters * 1 mile / (pi/4*(3mm)^2) = 22.77 ohms`
	> a drop cord is like... half an ohm
	> you would need to step up the voltage to nearly 10kv to get equivalent power
	> running a line at a constant 10kv doesn't sound smart. chargers pulse for a reason

### Improved fencing grazing solutions
- Adapting the GPS-style collars
	- Put a base station out and use some sort of radio time-of-flight
	- Put a base station out, use wifi or something to comm, but still rely on GPS
	- Use dog fence wire. Just lay it out on the ground, no need to worry about fence staying taut
- Temporary high-tensile wire to do alley grazing;
	- How tight can polywire go? around 180lb - density is 3.1lb / 1320 ft = .0023 lb/ft
	- High-tensile wire is 1500 lb - 99lb / 4000 ft = .024 lb/ft (10x heavier, 10x stronger)
	- close enough formula: `T = W*L/4/H = w*L^2/4/H` ; so a T/w ratio is constant;
		- .3 in: `T = .0023 * 30*30/4/.025 = 20 lb` 
	- Put up panels rather than stringing wire to prevent movement 
	- Use a tractor as a back-fence rather than as the whole thing
- Super simple tractor made of cattle panel
	- Pallet back
	- Trampoline top
	- 
- All-in-one automatic winch like Thomas Massie's https://www.instagram.com/repthomasmassie/reel/DCEvt4Ugi9y/
	- 100lbf at 20ft / hr = .75 watts
		- This is... so doable with a solar winch, at even tiny efficiencies
		- 2000 lb winch pulls how many amps?

### Agronomic ideas
- Pastured pigs
- Interseed covers on corn
- Strip cropping
	- Sheep / cover crop grazing in corn
	- Pumpkins in sweet corn
	- Twin 60" corn with covers
		- Micro-chicken tractor!!
