Compressed Air Powered Transportation and Tools
« on: June 12, 2018, 05:26:01 pm »

For me it all started with this hard to explain streetcar setup, where a streetcar was being pulled by a horse. This is one of those instances where an official explanation was running into a sharp contradiction with common sense. I was always wondering why people would go through the hurdles of developing, producing and installing a whole rail system to just use it in a horsecar combination. This of course, had to include the development, and production of the actual car. Just like I mentioned, the rig became known as a horsecar.

Wikipedia contains its own explanation of this horsecar occurrence, “The horse-drawn tram (horsecar) was an early form of public rail transport that developed out of industrial haulage routes that had long been in existence, and from the omnibus routes that first ran on public streets in the 1820s, using the newly improved iron or steel rail or tramway.”

The above sort of gibberish language and bogus explanation could never sit well with me. Common sense was suggesting that a normal person would never go the length required to produce the entire rail system to just pull cars with horses. Indeed, none of us would think that the below provided setups were intended to be used as presented.

The Amish power their machine shops and ceiling fans with compressed air. It's a way to harness wind power, for them.

I've never been sure why it's okay with God to use compressed air but not electricity. Maybe because its a  DIY tech that doesn't require an "outside" power grid, so they aren't tied to BAU, which seems to be a big deal for the Amish.

The ceiling fans are available for sale online , but they are not cheap.


Actually, the Amish have no problem with using electricity, as long as they harvest it themselves. and don't connect with the "culture undermining" grid.

The Amish Are Going Solar? 

By Jenny Lou Bement | Green Energy
 
Have you seen solar panels on rooftops in Amish country? According to NPR, the Amish population in Ohio is steadily adding solar power technology to their homes. In fact, it reports that 80% of the Amish in Holmes County, Ohio, are embracing this renewable energy. Although a handful of families refuse to take advantage of solar electricity, even some of the more orthodox Amish are excited about the incorporation of solar power. At first glance, it seems strange but, believe it or not, it makes sense.

If there's a community that has held tight to its traditions, it's the Amish. With their own language, way of life and near-absolute separation from mainstream culture, or "English" as they call it, the Amish are famously known for their strong ability to live off the fruits of their labor rather than technology. In general, they live without cars, television or electricity but with advancements in energy generation, some of this is changing. Like many eco-conscious, tech-savvy folks across the world, the Amish are reaping the benefits of solar energy.

Why the Amish are embracing solar


One reason why solar is becoming increasingly popular among Amish communities is the fire risk of their traditional lighting methods such as kerosene lamps and candles – especially for the elderly and younger members of their communities. It also gives their communities the ability to have cheaper, cleaner electricity with the perk of remaining off the grid. In a nutshell, solar is a win-win for the Amish – they remain off the grid, preserving their culture while reaping the benefits of clean renewable energy when needed.

The Amish use electricity?

It's not that the Amish aren't allowed to use electricity, it's that they believe too much reliance on electricity or access to public power grids will tie them too closely to the rest of the world and hurt their well-preserved culture. It's not necessarily against their beliefs to have power. Before solar panels became readily available, the Amish used gasoline or diesel generators to produce their own electricity for a handful of luxuries – lighting and, in some cases, household appliances such as washing machines.

The Amish don't believe electricity is bad; they believe having ready access to it will create temptation that can lead to television and other electrical luxuries that could hurt their values. Their culture values hard work and while they may appreciate appliances and tools that can make their jobs easier, the general consensus in their community is if they have complete access to these technologies, it will compromise their children's work ethic and could lead to a tarnished version of their way of life over generations. With solar, there's less risk of diminished values and mainstream culture, just as with generators. The big difference is – it's better for the world and 100% renewable.

I understand their worry that electricity can lead to television. Definitely a bad outcome there, and I'm not being the least bit tongue-in-cheek.

I hope they don't let that happen. Solar PV is fairly new. I wondered if they would embrace it. They've been using compressed air for a long, long time, and no one else seems to use it.


The French came up with a compressed air (very small) car about a decade ago.

They claimed it would be cheap and easy to fuel renewably with electric compressors powered by renewable energy sourced (PV and/or wind) electricity.

Tata motors is licensed to build it, but apparently they haven't decided to build it.

Also, don't forget that every mechanic out there, who has a shop and changes tires routinely, uses compressed air powered tools.

Compressed air power has its niche in civilization. I don't think it will ever go away, simply because it is so cheap to store energy in the form of compressed air for immediate, on demand use, even if compressed air cars never become part of the transportation picture.

Interesting.

I have a big compressor, but my wife made me take it out of the garage because it was really noisy. It's in storage. I have a few air tools, from the days when I thought I wanted to learn to paint cars. More recently, all the power tool makers have come out with alternatives to air tools. I have an electric impact wrench, for instance. When I was young there were no electric impact wrenches, or at least I never saw one.

The high speed air turbine is still my default dental drill (handpiece, we call it), but they have good electrics on that too now, which some people prefer.

The Amish use windmills to compress air, which is kinda cool.


Agreed. 

And that sound of that high speed dental drill is something no person who has ever been to the dentist can ever forget!  ;D

I've often wondered why compressors are so noisy. Sure, the physics involves all the vibration frequencies that are blasted in every direction from air that don't wanna be compressed, so to speak, but there is a sneaky way to get around that. I know they use that with mufflers. As you know, if you can get two sound wave frequencies to interlace a certain way, they cancel each other out. If they can do it with car mufflers, why not with compressors? If you put your thinking cap on, I'll bet you can make your noisy compressor purr like a kitty so your wife won't ban you from using it.

Here I show you a mod to make your air compressor a few decibels quieter. I reduced the noise by 4 decibels. What's left is mostly valve noise, and that noise can only be reduced by putting a wall between me and the compressor. This technique will work for any compressor, such as Eaton, Polar Air, Ingersoll Rand, Campbell Hausfeld, Quincy, etc. This technique will not affect your cfm.

Here's another sound reducing method. This is  the old "Dissimilar Materials" sound proofing technique with many applications. He also forces the sound to make two 90 degree turns. This quiets the compressor down much more. I suspect he is creating a partial sound destrucitve interference pattern with these forced turns.

For plans, click "Show More" below. --- Make your generator or air compressor 5x quieter using a box  that can be disassembled and stored.  I also show the exhaust system that prevents carbon monoxide poisoning.   I show a video of my 3500 watt  generator running alone, and while it continues to run I assemble a quiet box that I built, around it. The video shows the audio waveform of the generator's sound decreasing as the box is assembled, and my video editor's "db full scale" meter is also shown in real-time. Finally I show the generator running alone and compare it to the generator running in the quiet box in 3 second bursts to allow you to hear the before and after difference.

I also show the exhaust system that vents the generator's exhaust high up above the roof to insure that carbon monoxide will not get into the house no matter which direction the wind blows.  Because of this, the generator can be run in our carport out of the rain.  An additional benefit is that the exhaust system helps with quieting the generator without adding a secondary muffler, by routing the "exhaust sound" above the roof.  Two benefits for the price of one.

Finally I show how the panels of the disassembled quiet box can be arranged for storage in the bottom of a small clothes closet -or- in a small footprint configuration for storage in an even smaller footprint space.

UPDATE:
I was not planning to do this but because of requests to buy plans for my quiet box, I put a package together that consists of plans and step-by-step instructions for building my quiet box and both sound baffles. Also included are a video, plans for 2 larger size quiet boxes, and the Sketchup files for my quiet box and baffles.  If interested with no obligation to purchase, send a request for details to usefulgizmos@gmail.com. If not interested, please just ignore this update.  Thank you.
