I'm writing to ask for your support and just spreading the word to folks who would like an improvement on how their animals are watered.
My name is Ryan Luther and I've just launched a Kickstarter Project to prototype a trough heater that I've invented;
low voltage, controlled temp, and safe!
If you could take the time to read the story and watch a short video of a model I've tested I'd be grateful.
Best wishes to you and your family!

This is a battle that has been fought for a long time, an insulated trough, (tough enough to withstand animal shenanigans) is far easier / smarter / on the pocketbook than constant power input.
What power input you do spend can be minimized by simple physics....A; heat rises, B; exposure to air is all that required for aeration.
With the caveat that Its better to hydrate animals with adequate quantities of water, than to give them an inadequate supply of "fresh" water!
So.....to my simple mind a double walled trough with at least eight inches of insulation between two animal tough shells is the best start, then a simple 4" stainless tube passed through within 2" of the bottom, with caps, to contain 2 60 watt halogen bulbs in series for heat.
(Halogens create an extraordinary amount of heat for wattage input, wired in series they last forever because they are so far below their max power constraints, they are available cheaply everywhere!).
Aeration is accomplished via simply rolling the water from bottom to top because .....heat rises! But if you wanted a more dynamic aerator then put your heat source at the bottom of a "percolator" arrangement.
But!!....... the hotter the water the faster the evaporation, And!....the more water is exposed to air in the processes of aeration the faster the evaporation....so unless its attached to a float valve with a constantly on source, perhaps moderately stale water is preferable to clouds of steam building rime frost....
Nothing is foolproof to a sufficiently patient fool!
I hate people who use big words just to make themselves look perspicacious.
