I received an email seeking bids on a complete solar-with-generator-backup system I thought would be interesting to some. A complete "portable" package large enough to power most doomer compounds in style:

SUN ELECTRONICS Mobile Renewable Energy Unit

Introducing the Mobile Renewable Energy Unit (MREU) from Sun Electronics. The MREU is portable and designed to integrate into existing utility grids in permanent military base environments or with Forwarding Operating Base "Micro Grid" environments during deployment to active military theaters.

The core differentiating factor to the MREU is the low maintenance 90%+ efficient Lithium Phosphate "Never Die®" battery storage with proprietary energy management technology that optimizes every kilowatt-hour produced by the system.

The MREU seamlessly integrates with its standard 30kWp of photovoltaic solar panels that can be deployed by just two people in a matter of hours using FSE's proprietary "Smart Solar Array Setup System©" (SSASS) technology. As a backup to the MREU's renewable energy generators the system includes a 35kW diesel generator that is designed to run at 100% optimum efficiency to decrease the "Fully Burdened Cost of Fuel" that is so critical in deployed environments.

Tested at US military facilities the MREU is a proven deployable energy production, storage, and distribution system for extreme environments.

Unique locking system
Easy to deploy adjustable solar panels

GENERATOR MODULE
Standby power rating 63 kVA-35 kW @ 60 Hz

Im just waiting for the right battery tech to come along... I just want a small storage of say... 3000KWh. :roll:

Today that amount is completely and utterly out of my reach..

wow! where do I sign up? Let's go camping, happy ever after.....

3000KWh is barely enough to go off-grid here in Denmark - if you want to use the electricity as heating also. The production is mainly in the summer - so I need to store for about 100 days worth :-)

Let me dream about that perfect battery ... that i dont have to pay 20x6800$ for .. and doesnt wear out.

Yeah, Peaky, and folks in Egypt probably don't invest in snow machines either. Few technologies apply everywhere. Then, again, I hear property is cheap in Spain

Heat is best converted directly from solar radiation, not through PV.

I get it, though. All the toys we want are too expensive so let's whine about it.

Wrong.

Both are useful. Passive solar is great when the sun shines in winter, but when it doesn't for an extended period of time, an efficient wood stove helps maintain the internal thermal mass's temperature. But the stirling engine is more about achieving work from heat in the most efficient manner (it is theoretically as efficient as the carnot cycle). It's always been one of my goals to create a modular stirling engine with an external hot-end heat exchanger that could integrate into a wood stove or a tracking parabolic dish depending on climatic conditions.

And the way to get the most out of wood:

Yes, I've done my doomer homework regardless of whether I've put it to use in my current living conditions.

I had a Russian colleague in one job and she was amazed that I knew about them (she had one installed in her house in the USA). I guess being a "prepper" does help expand your cultural horizons.

I don't know why anyone would ever build fireplaces on the side of houses rather than straight up through the middle. Sounds like a no-brainer to me.

Because solar power is cheaper than storaging, it has more sense to add solar power and reduce the amount of storage to a couple weeks of low consumption or something like that, with a peak solar power for a 20% surplus over the shortest day of the year.

Of course that not work if you are to near the poles. Then, you should use solar and wind mix, with a great use of wind on winter because solar is mainly off.

In any case, flow batteries was the right choice if the technology was ready, because decouple power and energy storage, doing storage a lot cheaper if you not need to add more power.

I did want windpower, but the rules in Denmark are FUBARS. It is simply not possible for normal people to legally put up a windmill.

And I am not whining about nice batteries; I am dreaming nice dreams about them. But, I understand why some people are not able to make that distinction.

I speculated about wood stove, but decided against it since the danish rules demand that you let strangers into your house at least once a year to inspect oven and chimney. For that they get 200$ and it usually takes them about 10 min - and they are considering putting substatial taxation on "wood power" - starting with a tax on all wooden fuels - they call it "delivery safety" tax.

I wonder how much of the tax that is being used to actually guarantee a future delivery of say wood pellets..

Can you grow your own wood (as, say, a short rotation coppice)? It could be good feed for a Russian-style thermal inertia stove (as smaller branches are better).
