Life goes on - Summer 2021

Not saying you did anything wrong Cody because I don’t believe you did, anyone can get blind sided. But this is where some military training, woodsman ship like hunting, and self defense training is very prudent, I preach it all the time. SITUATIONAL AWARENESS! Always be aware of your surroundings and what is going on, now you HAVE been blindsided, you will always be watching your mirrors, more aware of other drivers and find yourself becoming proactive instead of reactive. I deal with it every day commuting into the big city full of idiots unaware they are barreling down the road in a 3000+ pound lethal weapon.

Oh I saw them coming. There wasn’t anything I could do being in the right hand lane. No time to speed up and too late to brake.

Well I cannot agree more with your driving assessment Marcus.
Daily driving both the wife and I have to multiple times be-aware; evade others aggressive, inattentive driving . . . or - CRASH.
I just viewed a study classifying the U.S. states, by state for aggressive/rude driving.
California was #1.
Oregon/Washington #2.
The state of Virginia was #3. Because of the Washington DC and Richmond areas.
Then on down with New York, Illinois and others.
Ha! Cody: North Carolina was on the polite driving states list.
But it only takes One-person; One-time, to ruin your day.

Change of topic:

An easy lesson here. Just a 26:21 time commitment.
Back in 1999 I had to study three thick books and spend hours and hours memorizing to pass certification tests and then get to hands on learn these working for pay.
Foster girl’s Mothers 1997 Chevy/Geo Metro threw a check engine light and would not hot idle smoothly.
My 1994 upgraded many time Snap-On old red brick scanner said Intake Air Temperature sensor circuit #1 problem.
Throttle Body injected. IAT is in the round hat air cleaner housing. Just unplugging: the one sensor wire broke in half due to a long ago unsealed pin prick testing probeing, and now 25 year old heat hardened wiring outer now. Right at the wire into the polarized hard plastic end plug. Too short to repair.
New sensor from the auto parts store.
And a full two hours walking through a big You-Pick-It yard to finally find a harness end.
1st gen Geo’s; wrong harness ends. 1995 2nd Gen: right body Geo - different sensor so wrong harness end too.
None of the rigs in the Import aisles or GM domestic aisles had the right plug end either.
FOUND IT. Truck side of the yard on a four door Tracker.

Their Mother cannot decide if I am a genius, or just lucky. Happy to be back idling well.

Here is the joke.
She keeps berating me about my shirt pocket flip cell phone.
Say’s I need to get with the 21st Century. That I need to social media participate, too.
And she just since upgraded her only 12 months old touch screen smart phone. Six phones in the 5 years I know about. Soul sold bought-in.
I’m on #2 flip phone in the same time. ONLY upgraded because of a forced change from perfectly adequate 3G to 4G.
Some value aspects you certainly want to be 20th Century. Even 19th Century.

Working knowledge has been; will always be; a continuous pursuit endeavor.
Just can’t be as BruceJ said: a Luddite. Use Technology. Well use, proven, costs depreciated, Technology.
I could have adapted in almost any of those other versions IAC sensors; harness and all.
But then would not have had the excuse to “Possibilities” wander around!!
Seeing Toyota Hybrids in the You-Pull-It yards now too.

For all you maize growers out there. Don’t forget to nixtamalize the kernels or you’ll miss out on the vast amounts of natural niacin that corn provides. Without it you won’t even hardly get empty calories.

The kernels can be dried and have a longer shelf life than standard kernels. Some people call this Hominy.

Hello Mr. Steve, this refrigerator works on R600a - isobutane, which has similar properties to R134a, but I used LPG (liquefied petroleum gas), which again has similar properties and is a very effective refrigerant, the price is 0.74 € / l. I also have LPG in the air conditioner in my Subaru (300g), it works great.

I have heard of people using propane as refrigerant in the ice business world years ago. OSHA (governement safety regulators) shut it down because a compressor on a merchandiser in a grocery store locked up , leaked and sparked , and kind of exploded. But I have been thinking about returning to it in non retail settings possibly. And possibly in the developing world where commercial refrigerants are not readily available, and propane is. Problem I have had is that all the people I ever knew who were old enough to remember it are dead now. WHat do you know about the safety concerns, etc…
the old-school propane delivery guy we use because he will still fill any tank we have…says that it should be plenty safe…that there is just too little in a refrigeration system to actually be dangerous, and that it’s a lot harder to cause an explosion with it than people think.
I know that the movies have it all wrong…shooting tanks and having them explode, etc. Been there, done that, got really disappointed.

I would be very interested in any and all info someone might have that comes from real world experience.

Same here! Also can we mix propane and iso butane to tailor the condensation pressure? I have been itching to do experiments!

LPG is a mixture of propane and butane, in which the proportions are adjusted to the season, more butane in summer, more propane in winter, the pressure depends on the ratio and temperature.

Well I can tell you a leaking propane regulator on a home tank one of the tanks about 3 feet tall and 2 feet in diameter I guess the standard one someone has with a gas stove and hot water heater will infact burn down the entire house before the fire department gets there. My best friend’s neighbors house burned that way back about 20 years ago now. It went up in one big fireball in the corner it the house and the shed where the propane tank was.
The problem I see is it doesn’t take much to get an old dry house to burn. Maybe if you could setup a remote compressor out on a separate pad from the house it would be safe enough as the fire ball would be self contained.

The use of flammable cooling gases is of course dangerous, they are also used as propellant in various sprays, paints, hair sprays, … caution is used in the first place. Refrigeration units should be outside, as you say Dan, and filled with a small amount of 1-2 kg of refrigerant, and heat transfer to the house (glycol, salt water) will not be a problem or danger. LPG is heavier than air, so stay away from the basement.

my intended use would be in freezing units separate from houses or stores. isolated away from people.

Hi Tone.
Thanks for the response.
And you are able to use a standard refrigerant grade of mineral oil lubricant, yes?
Not an expensive PAG or other semi/full synthetic?

For some reason l find it strange to question 300g of LPG in your cars cooling sistem while most haul about 10 or 20 gal of petrol on board, wich is just about as dangerous as LPG…

7.7 kw to grid maintaining battery voltage .
Lambda control for propane conversion is shot . valve not moving .
Need 12 volt gas shut off .
Now I have unit all these units in all these buildings running just to see if it can work .

Propane is used as a refrigerant in South America a lot. Propane is a fairly close drop-in for R-12. (think older US refrigerators and freezers). Mineral oil can be used as a lubricant. Propane is a good solvent and cleaner in older used systems. So any gunk in the system will clog the expansion orifice. I ran into this years ago when I shipped a semi trailer of used commercial units to Bolivia. They installed them and they ran a short time and stopped. I didn’t realize they were going to use propane as the refrigerant. Orfices were plugged. They needed cleaned and I sent them some burn-out filters. The best filters for the application. As we know from woodgas there isn’t a filter that will stop every contaminate in a gas. Please remember that propane is heavier than air and will settle and accumulate in lower spaces.

Can’t get to work since holidays, I have to get this out of my head. So I decided just to try some.

Build from pieces around. And at moments like this, it is very helpfull to have a cnc plasmacutter.

Based on Joni’s design

Made the reduction in a flat plate. Is that possible? What kind of problems can occur?

And under reduction a dropbox with outlet totally down, so heat has to go before gas can leave the dropbox. Gas is sucked though a 6 inch/160mm pipe for low speed. Then through a needle felt filter bag 4 foot/1300 mm long. Way to big but it is a leftover.

Separate parts, not complete, memory of the phone was full.

Fast start up, burned my hand, dropbox has to adjusted some. And a few big pufs/backfires! With a diesel? Or airleakes?

Maybe, some day…

By the way. Only to get my feet wet. Only two toe so far. Not worthy it s own topic.

Hi Joep, thanks for the clips. Are you gasifying charcoal? Have you tested the quality of the flame? Do you reduce the speed of the diesel engine, or do you limit the amount of diesel fuel injection?
