Aha. So. We can't accept the normal brake failure excuse.

That'll be when the bridge was free I used to do the same with KB TV's Where's the turret tuner in that picture?

i just did a quick google. X-Ray was the story I was told at that time, and it turns out to be true but only for voltages in excess of 16kv. Protection from external magnetic and rf fields is important for longevity and interference proofing.

There's a video showing well dressed shopfloor workers making valves. Must be from the 1940's https://brimaruk.com/valves/brimar-tube-range/

Didn't those things need special X-Ray proof enclosures?

Me too. It was part of the power supply for the punched card computer system in the CWS building in the centre of Bristol. Mechanical card readers and valve computer.

As we progress up the endless road of.........progress, we (I) find ourselves getting forgetful of where it all started. Fixing crystal radios so you could almost hear the light program. Making that first amplifier with transformers and valves. Figuring out how to solder wires to valve basses. wondering why heaters were 6.3v. Can you remember your old valves? I can and what's more they are still in production. take a look:- https://brimaruk.com/valves/brimar-tube-range/

I'm sorry to tell have to tell you but you are way behind the times. We have been doing this in Buriram for many years now. Husks are recovered from rice milling and used for chicken and cow feed or ploughed back into the soil for texture improvement. Rice hay is baled up for buffalo feed and anything surplus to that, which is quite a lot, goes to the local biomass plant or gets ploughed back into the soil for texture improvement. We do very little burning of sugarcane and rice residue because of the value of the "leftovers" for sale to the above. Granted, some farmers do burn but they are the Six Rai or less guys for whom the "leftovers" are not enough to pay for their harvesting.

Quite right but the pollution added by the manufacturing of such equipment is relatively short term and small on volume, whereas the panels, cables etc. will be saving on pollution production for the next 20 - 30 years or so. You are producing clean electricity but PEA supplies dirty electricity.

Take your remote control to the shop where they sell receivers and see which receiver it will activate.

The sizes of 4mm and 2.5 mm ( AWG 12 and AWG 14) are fine.

Lots of good thinking going on here. Personally, I would place a bit more emphasises on harvesting for gardening et al. Depends on what is fun for you and yours though.

Well yes and they supply a C of C too.

Yes but a bit industrial. That's the sort of testing done at chemical plants and by our village builder...........

Thank goodness I'm over 50...........

There are positives in going solar with batteries which transcend the financial aspect. PEA buys and supplies electricity from environmentally dirty sources. That is a good enough reason for me. Lead acid batteries are relatively clean to manufacture and have a 98% recyclable content. Scrap value is worth about 18% of the original purchase price. Oops. That's part of the financial aspect. The big deal for me is the independence I enjoy from reliance on supply from a company which can, and does, change prices and suffers failures from time to time. So payback time is not so relevant for me. More important is the fun I have doing it.

Some few weeks ago I mentioned that I would give a progress update on this technology. First, for those that are unaware, lead carbon batteries are lead acid with carbon added to the -ve plate mix. The batteries I bought are Gel Lead Carbon. They are installed in my new inverter stable with most of the existing kit from the old room. I needed to extend a few wires to connect to the old system. The batteries behave very differently from the Gel's they replaced. Detail. Each battery from CSPower is 250Ahr and weighs 77kg They are arranged to give a nominal 48v at 750Ahr Charge controllers are 60A 48V from SRNE. What is different about my new batteries. They charge much faster. They can be discharged by 80% every day and still give 2000 cycles. My discharge pattern is 30%/day which is good for 11.6 years. They run cool. Temperature range is 20ºC to 30ºC So far the installation has gone well. The new room is built using AAC blocks which I eventually got from Thaiwatsadu. (There was total non-availability for a week or so). Old wiring was extended to the new location and everything worked fine from switch-on. I may be adding environment control but the AAC blocks are keeping out external heat very well so we shall see. Here's a few pics of the installation. The dangly wires are feedback to the charge controllers of battery voltage and temperature. The big black box is my 8kW, heavily modified, inverter. Other boxes contain protection and isolation components.

When a foriegn visitor dies medical authorities report it to police who inform the embassy and immigration. That's what should happen so in this case immigration must have neglected to update their computer.

I also thought about Redflow as a home ESS solution and contacted the Ausie firm for prices etc. This was before manufacturing in Thailand. They gave me the contact number etc of a company in Chiang Mai who offered a ridiculously high price. Did I buy? Never in a million years.

That's really big. Any advances?

Yeah. Think about the fruit picker who maybe had a pooh and didn't wash his hands.

Redflow is an Australian company making Zinc Bromine flow batteries.They have a manufacturing plant in Thailand. These batteries are priced well beyond reach of consumers like me but are ideally suited to grid scale applications and remote base stations etc. This installation will be in California where they think really big. https://redflow.com/project/redflow-to-supply-20-mwh-flow-battery-system-for-project-in-california

Cheaper than buying petrol or diesel that's for sure. Have you done a cost comparison with different fuels ie PEA electricity V petrol?

I am wondering if MEA and PEA are taking a keen interest in this forum. Also there are quite likely a few jealous non solar users living nearby who would think nothing of reporting farang solar activity, legal or otherwise, to their local electricity company. This may be why I'm seeing an upsurge of anti meter reversal activity being reported on here.
