What Should I Do With Excess Power Off-Grid?

solid state h2 storage is becoming very real even diy these days although im not sure if it gets near the efficiency of trees
 
Most days I top out my 14kwh battery bank before 11am. I thought about doing crypto mining, but my internet is abysmal. Any other ideas?
Just FYI for Crypto Mining you only need an internet connection for data syncing, which requires very little in terms of connection strength and bandwidth. There have been instances in which systems have mined Bitcoins successfully with as low as ~500 Kbps, which is nothing - dial-up speeds. The hardware is more key.
 
I mean…
You could get another 14KWh of batteries…
Or 28… store it for when you need it more, and lighten the drain load he bank sees now. Extending the life.
 
It crossed my mind but there's liability/trust issues and if someone got wind of a 'power cable' running from my house to the neighbors.... or a neighbor's house caught fire or xxx. Yikes.
Since we're growing a lot of fruit trees, we're probably going to be running food dehydrators with the excess in the future.
 
I currently use 2-50gal water heaters in series. The first water heater I put on a smart load circuit with my sol-ark12k. That energizes based on parameters you set for SOC% like 95% or 100% and also what minimum PV power this can be applied. This reduces the need for the 2nd water heater or last water heater to turn on after dark when people are taking showers. If the day is cloudy than the 2nd water heater will have to run at night. In that case I made that a heat pump water heater so at least it doesn't need 4500w running at night.
Typically my smart load turns on around 11am as well. I'm considering adding a 3rd water heater just to give more storage and maybe go 2 cloudy days but reduce the elements to 2kw in the 2 electric water heaters...The smart load can handle 40amps at 240v max.
I'm considering running hydronic under pex floor heating with these water heaters for supplemental bedroom and bath heat. Also I'm considering dedicated circuits run to each bedroom for an outlet to run a dedicated oil filled heater with thermostat taking maybe 1kw max for each. Lots of options with smart load. In the summer time I'm considering running a pool pump. Much harder to handle excess power in the summer I think unless you can pump water and store it at pressure or pump air and store that at high pressure with a release later to generate power however a lot more complicated. I really don't want to get into chilled water hvac because that is a lot more expensive for commercial off the shelf items than 20 seer heat pump units.
Crypto mining sounds good but am not sure it will be worth it if crypto goes to 0 when the fed coin comes out and or all govs make it illegal.
This guy Ourcoolhouse.com had a very cool site, excellent detail and monitoring for sub floor hydronic heating:

How about sharing approximate Latitude & Elevation, so we know if we should seriously suggest heating and/or air conditioning suggestions.
As you can tell, we were having fun while you were away. ?

Geothermal is a great idea.
 
mining rigs are giving less return and costing more, also outdated so fast.
but i mine gridcoin so jokes on me!
I guess that's the real reason why I'm leaning away from the crypto option. Which shitcoin would still even have a chance at being profitable from mining? I don't need excess heat in my house either. Temps are perfect here year round.

I have two gpu's mining ETH. They aren't making much $ per day but they are producing 275ish watts of heat in the solar shed. It pays more than the kwh used. About 6x in this crappy crypto market.
