Green energy is dumb

Glad to hear you have a different water system for winter watering of 350 head. The one mentioned previously seem very problematic as to freezing at slough surface..

Your setup of training cows to have no preference between "eating snow" and having abundant water available seems like something we could all learn from. Care to share how that is accomplished?.

Anthony Watt explains how global warming is a computer-generated phenomenon, subject to "adjustments to data" that are subject to biases. Go figure! I would have never believed it! But I do have a science background and have generated laboratiey data and adjusted somewhat to prove my point so I guess it is totally plausible that people at NASA and other temperature data compilation centres with an agenda that reflects upon their livelihood could possibly "round up".

Aside from the adjustment aspect, there are up to ten other "known" reasons to doubt the data. Feel free to google the article Chucky.

Frost free pumps work with risers and an insulated top
They don't freeze because they take advantage of geothermal heat.


We used to have thrifty king waterers from Ritchie in MB. No heat in them. As long as cows drank they stayed free of frost thanks to insulation and the heat rising from the riser tube burried to 16'.


And yes solar fencers work with small... Very small solar panels. Super high voltage and extremely low amperage.

Especially on a short fence like that.


I see no problem with what grassy is doing and it works...

LOL, you think you're a genius oneoff but instead of being ahead of us you don't realize you are a lap behind!
Of course I know the limitations of that watering system. Once the source freezes over hard enough to walk on you place a couple of small bales of straw over the pump/intake pipe and that keeps it working down to -20C.
You don't need to teach cows to eat snow, they're often smarter than their owners! There are many times we have wintered cows completely on snow but the conditions don't always allow this. Cows on any type of extended season grazing where they are eating through snow are already taking in a good portion of their water requirements. Our herd's preference in winter is to walk once a day to water and lick snow the rest of the time if it's available. And you know what? the research proves that licking snow is actually better for the cow. Cows create a lot of heat while digesting forage which they have to dissipate and this fits well with taking snow on board in small quantities throughout the day. For the cow to go to a trough and drink her daily fill in one go taxes her body considerably more as she suddenly has a large volume of cold water to warm up to body temperature.

Grassy...I'll save the word "dotard" for later

Grassy...I'll save the word "dotard" for later; but for now an open plastic trough and your solar bilge pump (in the dead of any prairie winter) would have been cursed and problematic in the very near future.

From your conference board of canada link
"Putting renewable and nuclear energy in context

Sources of energy that produce low amounts of greenhouse gas (GHG) emissions include wind, tidal, solar, biomass, nuclear, hydroelectric, and geothermal.

Increasing renewable energy’s share of total energy consumption should be a policy goal to mitigate climate change in Canada and its peer countries. Nuclear electricity generation may also have a role to play in reducing Canada’s carbon output".

My thoughts:
Hydro is a good option. Canada has a lot of hydro capacity already. Every new hydro project should be evaluated on its' own merits. We should be looking at all options based on economics and environmental risks and benefits. That's why wind and solar are on the table where it makes sense.
that's something I don't understand ; why haven't a lot of coals plants been converted to. natural gas. ?
Many people think it is a black and white decision. Either you are in favor of renewables and opposed to fossil sources or opposed to renewables and in favor of fossil energy.

For the time being we are all dependent on both if you consider that Canada is a major hydro producer and using a lot of coal in Alberta, Saskatchewan and Nova Scotia.

We shouldn't be retrofitting or building any new coal electrical generation in Saskatchewan or Alberta. Gas is abundant and being wasted in the oil industry with a large number of flares. Convert the coal plants to gas as an interim measure to reduce carbon emissions by 1/2. Its much cheaper than carbon capture and storage so says Sask Power.

why aren't we generating more power with natural gas ??

Grass....

My 2 cents....if you make the water come in on the side and make the water spin....with an overflow back to the slough it shouldn't freeze....may need a cover with a couple holes but moving water rarely freezes....

Our trough an old steel wheel and is fed at the bottom at the outside diameter which creates the spin .....the overflow is in the middle with a pale over the top so shit like grass or leaves doesn't plug it up....very rare it has ice. ..feed with a quarter inch hole in a valve from an artesian well....

Thanks bucket but it works just fine as is - I never claimed it was our winter water solution but it's quite workable down to -20C. With that pump the water is moving way too fast to keep it running and overflowing - would take way too much battery to run.
My point in posting this was to prove that solar is a viable solution to the naysayers who claim their solar patio lights don't work on an overcast day. My point stands - solar has considerable potential.

I was going to let this go...but then grassy had to sayMy point in posting this was to prove that solar is a viable solution to the naysayers who claim their solar patio lights don't work on an overcast day. My point stands - solar has considerable potential.

My point is that solar patio lights and electric fencers may be near ideal uses for solar panels. For "mission critical" applications like a small recreational rural airport runway; even they installed cable between lights and connected to the grid. Everyrthing should have admitted limits and "considerable potential" still means limits that are best wisely respected. An adequate dependable winter watering system is important to an intensive livestock operation...and any livestock operation too.
But those who choose to publish their bright ideas as examples of how intensive livestock operations can water 350 head of cattle need to initially point out potential shortcomings upfront. One of the common characteristics of such promoters is to leave out key information; and seem to end up with a summary like[This was to prove that solar is a viable solution to the naysayers who claim their solar patio lights don't work on an overcast day.

Well the picture and example given by grassy uses a solar powered watering system that "works just fine" to attempt to show that solar can easily replace almost everything else. The details that have to be pryed out are that the writer only reluctantly admits (or won't even contemplate) that
eg, -20C is not the coldest weather in the prairies. In fact its only a little below -2 degrees F.

Secondly solar panels aren't capable of production but maybe 15% of time under ideal sunlight and panel operation conditions. In winter at these latitudes that output is diminshed to the point that December and January electrical production is typically DISMAL.

Third water pumping is apparently "open discharge" in this simple setup...meaning somebody has to babysit the watering of those trained animals who parade in to water without ever an overcrowding incident. Not convinced this works 100% of the time in the real world. Remember there is no water level control on that trough and there had better be somebody looking at more than skimming a little ice off an open trough with real winter conditions complete with brutal wind chills. And remember tha pump can't run continually; and if it did overflow the tank then a whole set of other problems will surface. Also it going to grow old watching cows drink water all day.

And finally making cows eat snow isn't an ideal method of providing water required for animals. As an animal I suggest that grassy report back as to how he likes a diet including only snowballs for moisture to keep body functions going. The comment as to how ruminants have excess heat production from rumen activity that can melt all the snow they need in place of water......only can be pushed to a certain temperature, stress and heat loss limit.. I doubt grassy should want to test that exact point with his 350 head of domesticated animals that are under his care and are his responsibility. Further he probably has no idea even when those limit may be close to being reached.
