This weeks picture. Things are moving along. The upper deck will have a removable Roman shade. The vertical poles need about 18” cut off them to
meet the 8M hight limit. The welder is finishing the frame for an architectural feature (Parapet) to complete the edge of the roof More soon.

I think you have gone above and beyond what is needed for sure. I'm just hoping you have an open house party, I'll bring wine, beer or whatever works!

It seems to me like the cost of construction wold end up being more than using standard construction methods by the time you insulate and cover the
interior and exterior walls, plus using containers really introduces a lot of design constraints.

I think he's already addressed those issues in previous posts.
Looks like a lot of progress, looking forward to more construction as the project develops. Nice work, RF!!!

Here’s a picture of the 240VAC port in the garage. There’s a level 2 car charger plug and a plug for welding and cutting.
There was an earlier discussion elsewhere about 240 vs 120 vac efficiency. The same welder draws 49A at 120V and only draws 22A at 240V. That’s
about 600W less.
I just ordered the 2nd inverter so we’ll be up to 6,500KW in panels (12X540) and 12KW of inverters with 10KW in batteries.
Since time is money even in Mexico, I think this house will cost less than a block house. It will be finished faster and with steel changes in design
are easer. Compared to wood construction the waste is far less.
Block houses using poured roofs are very complicated vs container roofs as currently poured roofs use lots of foam to insulate and reduce the weight
of the roof. (pictures soon). They need to be finished on the underside just like a container does.

it draws the SAME amount of current but on 2 lines
it DOES NOT save you money

B&S
W=AXV
49X120= 5,880W
22X240= 5,280W
That’s 600W less!
You are correct, since the electricity is free the cost is the same!

oh god...that is NOT how it works...
220v you use less heat
you make the same electricty as 110v
if you pay for electricty you pay the same
220v does not save electricty or money....
it runs electric stuff cooler
thats it

It's interesting that it takes fewer watts (less power) at a higher voltage. I wonder why. Wire diameter?

30kg propane tank is 8 gallons
850 pesos a tank
106 pesos a gallon
20 pesos to the dollar
$5.31 usa to the gallon
it is what it is

That makes sense..we pay a lot more per litre in smaller volumes too.
Makes sense for us to oversize the tank and refill less often. Cost difference between installed 250gal and 500gal is minimal, but delivered propane
costs are much lower on the 500 gal per litre.
I see global pricing on propane has been dropping fast lately tho, maybe it's substantially cheaper than last time you refilled?

Do they measure sale in SI units, using a calibrated machine?
Or are they selling using Pemex units, uncalibrated measurements?
Woke!

I screwed up on the calculations. Those are DC amps. The inverter reads out in KVAs too. I'll re do the test and get the right numbers. I don’t
think Bob can deal with KVAs though. The difference is I2R losses 1/4 the losses for 240VAC.
I’m glad we aren’t talking 3 phase. I wouldn’t want to try and explain why you can get 3 120VAC legs off of just 3 wires and a neutral! (But why
doesn’t the neutral explode, you're using it with 3 hot wires?) It’s not Tom’s DC power distribution!

L,
There’s a lot of stuff in Mexican LPG! I had to change the gage gasket on our big 300Gal tank and I pumped at least 5 gal of really nasty black
sulfur water out of the tank!

What other calculation have you screwed up building your new house?
Hire a professional!

Goat,
Probably lots! That’s why you over-design and have lots of alternate stress pathways! Remember Rosie Scenario is Murphy's sister.

Old School Concrete
For those too young to have done concrete w/o a pump. Yes, I think 3/4 rock is better than sand!

Nice work, good to see some good old "Manuel" labor. Looks like it's progressing well now you go the boxes set.
Is that another container in the background of the last pic? For supplies and tools?
