This documentary was made in 1972.

Probably a 16mm optical sound print that has not aged well. The first thing to go is some colours.

No, the Blue, now A line, has never looked better today. It's become the most used line on LA Metro surpassing the B subway line in 2024. It's also now the longest LRT line in the world. If anything, it's in the midst of it's golden era now.

Yeah, the golden age when homeless people didn't sleep on trains and crime was very low.

When I saw Bill Lear's poodle following him around, that said it all. There are a large number of brilliant retired scientists and engineers from the LBL (or Rad Lab) and its descendant, LLNL who were true geniuses of their day, now growing old and gray but still full of life and incredible smarts. And there are plenty of wealthy tycoons who hire them and crack the whips of progress. Regarding Learium, any good water chemist in the utility industry could detail the pros and cons of every possible additive. I've used deionized water in a megawatt-class steam plant but it is called "hungry water," it attracts metal ions and must be run through a resin bed or replaced regularly. And it freezes, not good in New York or Chicago. And god forbid you accidentally introduce any sodium chloride (resin bed cleaner) which dissolves the piping, or bacteria into the system, which quickly fouls it. Deionized water is apparently not the slightest bit antimicrobial. In the video, it wasn't mentioned what was used for a steam accumulator and there wasn't much room for one. For a vehicle application, rapid control of a variable firing rate is essential for the boiler. Unfortunately without a steady-state firing, boiler combustion can be incomplete, requiring jets of steam to periodically blast away soot which forms on the boiler tubes and the process exhausts black smoke, especially with liquid fuels. Single-stage turbines like the one shown are of relatively low efficiency. The piston version might have been longer-lived and lower cost, but of much heavier weight. It would be possible to build this bus today, with microprocessor control and multistage turbine, but the money and motivation just isn't there. One of the biggest challenges for public transport today is how to prevent violence and the use of firearms, and maintaining public confidence. Clean air takes a back seat to those needs.

Not to worry, you won’t be graded.

And the 8track cardrige.

Sadly the coach didn't have an 8 track player!

There was a little dude injecting hemp oil

Thought it was being pushed by the Union Pacific 4014!

The thermal efficiency of the steam locomotive is so poor because it lacked a condenser for the expanded steam. It just used the steam exhaust to create a draft for the firebox. Then it was released to the atmosphere.

They burned diesel fuel, but because the combustion was premixed and occurred at atmospheric pressure, it produced very low hydrocarbons, low carbon monoxide, low particulates, and low NOx. Probably almost idenitical to an oil furnace burner.

​@@MrShobarI wonder what the condensing pressure/temperature was on these. Most condensing locomotives didn't use condensers for added efficiency, only to improve water economy. Many of them suffered an efficiency loss due to high condensning pressure and the difficulty of getting sufficient condesing surface area.

It's almost surprising they didn't at least offer a big-block Chevy running on LPG or CNG with a THM400.

Kevin, I was in NYC, Queens when the Solectria Sunrise made the record breaking Boston to Ny trip on one charge . Prof Wouk , the Novelists brother Organized it .hr was prof at NYU and apioneer!

@@josephpadula2283 So wonderful you remember the event, which almost didn't happen! The Solectrians worked hard for long hours to promote alternative transportation. On the night before the event, the Sunrise developed an electrical problem and it was midnight before it was all back together. With no opportunity for a test drive, John Rogers drove it while indoors, back and forth 10 feet and proclaimed it was fine. We crossed our fingers and went home. Soon the morning crew arrived and took the Sunrise to downtown Boston for the big sendoff. Solectria's founder James Worden was not a man with a lot of time for trips to New York, and they didn't do a dry run. As a result, James got lost twice on the way to the Big Apple but still arrived. A camera crew followed him all the way to document the event and prove their was no cheating. When the Sunrise arrived back in Woburn, there was chuckling how the Brusa NLG level-one charger would take no less than two and a half days to fill the Nickel-Metal Hydride batteries which cost a tenth of a million dollars. The newly-developed batteries didn't even belong to us, they were on loan from the manufacturer. There was another chuckle about the network television interview on a Manhattan street corner, James lifted up a display model of the car's motor and transaxle using only his bare hands. He made it look easy, and it was, partly because the heavy induction rotor and steel gears had been removed from the inside. Not so much to make it lighter, but so the costly parts could be used in another car and not wasted on a static display.

@@kevinamundsen7646 Thank you for the history . Yes they were very late and we figured something had gone wrong . Who killed the electric car movie has the inventor of the NiMh battery that lent the batteries telling of him getting in trouble for doing it . I loved that car . I lost all my money in a company called phoenix motor car . We got so close we crash tested cars ! Then the investors had more stick than founders and Angeles and bankrupted the company . The next company was Tesla …..

It's just a number.

Actually the Brobeck Bus was quite successful and used in San Fagscrisco for quite a length of time. It used proven Doble steam technology and was as close to zero emissions as you can get with a combustion engine, the emissions being a little CO2 & water vapor.

"...Apparently Elon musk had a better idea..." And that was?

@@MrShobarcomparing your paycheck to his? Well than? 🤔🧨💥🫨🫨🫨😂🤣😅

Got a smoke?

Hey tandem, remember this! More doctors smoke Camels than any other cigarette. And don't you forget it!!

😂

I love the smell of tobacco smoke.

Everyone? Not the children with the cutely still developing lungs.

Sadly yes. Here in the UK there is the persevered steam ship Shieldhall. I remember back in the day many of engine room volunteers actually came from the electricity generating board as it was the only pool of steam experience locally.

Most all of your power plants still run on steam. There are a lot of steam engineers left. Siemens Westinghouse, General Electric, are all still building steam equipment until this day. Not to mention the navy ships that run off steam. It’s not common knowledge anymore but it’s far from lost knowledge. I know this because I am a steam turbine technician. 😅

@@shawnjosey8203 I was involved with Shieldhall 20 years ago. I don't know who manages the engine spaces now. So back in the day......... I really pissy little comments that say fuck all. Bore off.

Sorry to say no more Navy ships are steam except the Nuclear carriers and subs ! The Last Navy ship I know of was the Ponce and it had Civilian engineers running the steam plant !!! There may be one or two more but the boiler rate BT was limited a decade or more ago . Gas turbines for warships Diesel engines for Auxiliary type ships .

I think it *REALLY* helped that RTD was able to take advantage of Southern Pacific and Santa Fe railroad right of way to build out much of the system.

photo chemical smog comes from hydro carbons, first the LA basin is surrounded by a pine forest, pine trees emit hydrocarbons from the pine sap and needles, second the basin shape creates a perfect inversion layer to cook the hydrocarbons into smog and hold it, the indians people that lived here for thousands of years called the basin “the valley of fires “ because of the smog.

there were brush fires since the dawn of time. they make lots of smog

They brought back trains IE streetcars, and the subway system was introduced in the 1990s.

Do you Really mean the 1930’s solved car pollution ? Dont you mean the 1980’s with Cat converters and fuel Injection ?

The "Red Car" was actually killed by City Lines, Firestone Tire and Rubber, and Standard Oil. They colluded together to drop the price of bus fare so low that the electric railway couldn't make money, then bought it and dismantled it.

LA Metro has improved noticeably over the last year. I've taken it many times since June 2023 after not using it for 3 years during Covid, and it's been fine. I've had no issues. I've used the A, E, B, and D lines. Yes, you see homeless once in a while, but I've never felt unsafe or bothered. Ridership has continued to increase for the last 17 months that indicates feel better about using it.

Dumber than today?

@@petepeterson5337 Good question.

The 70’s were way cooler than today!

Blanket statements from another stoopid individual, who loves batteries and battery powered thingies.

You must be a climate denier. Calm down. Its a 52 year old experimental bus that didnt work and they have been using diesel ever since. That should make you happy.

@-fz1yg 😁 Nah...I don't know much or care much about the climate. I was just curious to see if I shook this tree a little, would a nut fall out ? One did ! 😉 Have a nice day !

It's kerosene.

This wasn't meant to reduce carbon. It was meant to reduce smog. 2 very different pollutants. For the sake of this problem, it doesn't really matter how much energy efficiency the fuel gives, as long the combustion produces fewer particulates.

Smog is caused by unburned hyrdocarbons, of which the average car before emissions controls emitted tons of. A natural gas burner on the other hand emits practically none. There's a reason you can cook a seven course meal with gas, but running a 1969 Cadillac inside a closed room will kill you in a minute.

EV-1 had a reduction gear but no transmission . Single speed.

I was about to say that too, exactly 1994.

Agreed big time
