Dude,
I get the joy and satisfaction of doing something by hand BUT, what you did here was ridiculous. Many hours x a whole month work by hand? vs a backhoe for 2 hours...
This is where the machine wins every time by a wide (logarithmic) margin .

Respect if you have philosophical/ financial or other reasons for not hiring a machine for half a day, but think of what else you could have accomplished in a month of hard labor.
As my brother likes to say: " never send a man to do a machine's job".

Just my 2 cents,
Andreas.

"And finally, not a battery at all, are projects like the Kilowatt. A 1 to 10K thermonuclear generator being developed by NASA for use off world. They last 10 years... at full output, but can be throttled. Probably safer than any of the batteries discussed above. Capturing the waste heat rather than radiating it would probably double it's effective output. Sunshine or rain not a problem, no snow removal needed. I suspect the liquid salt reactor would be too big for the average homestead, but probably ideal for a small community. (it would also be an ideal place to get rid of spent fuel from kilopower generators used on local homesteads."

'thermonuclear generator' - what are the waste products of this process? Something radiocative?
Also not sure about the wisdom of putting thermonuclear devices in the hands of homesteaders all over the world.... maybe I am not clear on the technology you are referring to?

Aquion is out of business, but Greenrock is a company in Austria that uses the same technology:
http://www.bluesky-energy.eu/en/greenrock-saltwater-energy-storage/

Made in Europe
Advantages: low environmental impact, high temperature tolerance, low- zero maintenance
Disadvantages: big/heavy, expensive

I am considering this for an off grid use in Portugal, I will not be there frequently, so the no- maintenance component is attractive to me

We are not the only ones thinking about this. How about this company, s water storage system. If the website is to be believed there is only a 10% heat loss over 6 months of storage. Looks like a massive storage system....

Does anyone here know or have any experience with solar roof shingles/ tiles made by this Dutch company?
Is there any reference on how they compare to the Tesla roof tiles?

However, links to the company,s website do not appear to be working.....

Many thanks,
