A kitchen experiment to demonstrate the power of condensing steam

What do you think about when you consider how a steam engine works?

Well you probably think about a fire used to heat water in a pressure vessel to form super-heated steam.

Then that steam is injected into cylinders in a controlled and sequenced manner to push a piston up the length of the cylinder. Piston rods and cranks are used to change the linear motion into rotary motion to drive wheels or gears.

Inertia causes the rotary motion, through the same cranks and rods, to expel the spent steam from the cylinder, before the whole cycle begins again.

But that's only half the story.

Steam engines also use the power of a partial vacuum created by condensing steam to produce linear motion in the same way, or to suck the hot products of combustion from the fire through pipes which pass through the pressure-vessel and heat the water.

What you will need for the experiment

An empty drinks can, such as a 330ml soda can.

A shallow container, such as a baking tray.

A pair of barbecue tongs or kitchen tongs with which you will be able to grasp a hot can without burning your hand or getting too close to the heat.

A source of heat, the cooker top in the kitchen is ideal.

How to do it

Step 1:

Thoroughly wash out the empty can. Any sugary residue might burn and smell.

Put about a centimetre (half an inch) of water into the can. Enough to cover the centre of the concave end of the can inside.

Step 2:

Place your shallow container next to your source of heat. This will most probably be a baking tray on the kitchen worktop next to the cooker where you will heat your can.

Put about a centimetre (half an inch) of cool water in the tray.

Step 3:

Place your can on the heat. It will quickly begin to boil because it only contains a small amount of water.

Wait until the water is really boiling and filling the can with steam.

Grasp the can with the tongs. You need to do this in an underhand grip which will allow you to, in one swift and smooth motion, remove the can from the heat, turn it over and plunge the open end into the cool water in the tray.

Do exactly that. As swiftly and smoothly as you can.

Here you will see the need for a vessel like a baking tray, the larger target makes the quick and smooth transfer of the can from the heat to the condensing cool water easier.

What happens?

The can is full of steam, which will instantly condense when the open end of the can is plunged into the cool water.

Bam!

The partial vacuum created in the can will cause it to be very quickly and impressively crushed.

The power of a partial vacuum is far easier to harness and is more powerful than pushing a piston along a cylinder with pressurised steam.

The mechanism of an efficient steam engine will inject pressurised steam into a cylinder during the phase of motion where the piston is pushed up the length of the cylinder, and inject a small amount of cold water into the cylinder fractionally after the full travel of the piston and as it is just beginning the return stroke. In this way the cylinder is both pushed and pulled up and down the cylinder.

But the condensing part of the cycle is far more efficient at pulling the piston than the steam injection phase is at pushing it.

The dramatic 'chugging' of a steam engine as it pulls away from a station is the part of the sequence in which condensing steam is used to create a partial vacuum in the smoke-box at the front of the engine. The hot products of combustion are drawn by this partial vacuum from the fire at the far end of the engine, through the pipes which pass through the boiler, increasing the efficiency of the heating of the water. The same partial vacuum

Five or six ways I could think of to roam the files of your Linux computer without cd.

pushd and popd dirs

https://en.wikipedia.org/wiki/Pushd_and_popd

The pushd command, when called with a filepath as an argument, saves

the current working directory in memory (via a directory stack) so it

can be returned to at any time, places the new filepath at the top of

the stack, and changes to the new filepath. The popd command returns to

the path at the top of the directory stack.

cd -

From man bash An argument of - is converted to $OLDPWD

before the directory change is attempted.

Variables

EXPORT mydir="/path/to/file/"

cd ${mydir}

History and histverify

Using !number from the history command will execute the command

[user@pc ~]$ history

1 cd tmp

2 cd ~

3 history

[user@pc ~]$ !3

cd tmp

[user@pc tmp]$

from the man command

shopt [-pqsu] [-o] [optname ...]

Toggle the values of settings controlling optional shell behavior.

...

-s Enable (set) each optname.

-u Disable (unset) each optname.

Now using !number from the history command will put the command on

the prompt but you need to execute it yourself

[user@pc ~]$ shopt -s histverify

[user@pc ~]$ !39673

[user@pc ~]$ cd tmp

autocd command

[ken@kalani ~]$ shopt -s autocd

Our old thermostat was breaking down to the point that we could not

change the temperature, so it was time for a change. And since smart

thermostats have gotten pretty good I decided that I wanted to install

one and take more control of my environment.

Introduction

Hosts:

MrX

Dave

Morriss

We recorded this on Saturday May 20th 2023. We met in

person again, and as before first visited the pub called The

Steading where we had lunch. Then we adjourned to Dave’s Citroen

car (Studio C) in the car park, and recorded a chat.

The region where we met is close to a village called

Hillend, which led to the show title.

Topics discussed

ChatGPT:

MrX did two shows in May using ChatGPT. He has used it more than

Dave has.

MrX has an iPhone and can use ChatGPT from it. He uses it as a

source of information when out and about. For instance, to find out

about the history of Musselburgh

Harbour.

MrX has also used ChatGPT to write experimental Python scripts.

There is a TED

talk by Greg Brockman, the inventor of ChatGPT.

Discussion of the Call

Annie app

ELIZA the program

that was written in the 1960s and simulated conversation well enough to

convince people.

Audacity/Tenacity audio editors:

Web sites: Audacity

and Tenacity.

Audacity

Wikipedia page

MrX and Dave have both used Audacity for several years.

Audacity was forked after it was taken over by Muse Group, and Tenacity was developed.

However, it doesn’t seem that there have been any releases on Tenacity

to date.

The most recent versions of Audacity have contained changes - in

particular the way the audio project is stored has changed. Instead of a

directory filled with various files there is now a single project file

with the extension .aup3 which is a SQLite database. This

was changed in March 2021 for Version 3.0.

Previously Audacity stored the project as a file called

<project>.aup and a directory called

<project>_data/ containing sub-directories and

files.

MrX reports changes in the way multiple tracks are handled. Dave

finds that the horizontal scrollbar has disappeared (which seems to be a

bug).

Dr John Campbell:

YouTube

channel

During the COVID-19 epidemic the channel contained a lot of

information about the SARS-CoV-2 virus, vaccines, disease, treatments,

etc, which seemed to be helpful and well researched.

At one point there was a lot of talk about Ivermectin as a drug that

could help with the disease, but although this received no support from

scientific research, it seemed to be receiving more and more exposure on

the channel.

From then on the quality of the content on the channel seemed to

deteriorate, and it no longer seems trustworthy.

Other sources have been critical, including Debunk

the Funk with Dr Wilson

The Doctor Who Exhibition:

Dave met with Andrew Conway and Andrew’s friend, and all went to the

exhibition held at the National Museum of Scotland.

The exhibition contained a lot of Doctor Who memorabilia, including

some original props.

Processing Standards.

The Federal Information Processing Standards (FIPS) of the United

States are a set of publicly announced standards that the National

Institute of Standards and Technology (NIST) has developed for use in

computer systems of non-military, American government agencies and

contractors. FIPS standards establish requirements for ensuring computer

security and interoperability, and are intended for cases in which

suitable industry standards do not already exist. Many FIPS

specifications are modified versions of standards the technical

communities use, such as the American National Standards Institute

(ANSI), the Institute of Electrical and Electronics Engineers (IEEE),

and the International Organization for Standardization (ISO).

Supporting Article: FIPS

General Information.

FIPS are standards and guidelines for federal computer systems that

are developed by National Institute of Standards and Technology (NIST)

in accordance with the Federal Information Security Management Act

(FISMA) and approved by the Secretary of Commerce. These standards and

guidelines are developed when there are no acceptable industry standards

or solutions for a particular government requirement. Although FIPS are

developed for use by the federal government, many in the private sector

voluntarily use these standards.

General KeePassXC Information.

 

Why KeePassXC instead of KeePassX?

KeePassX is an amazing password manager, but hasn't seen much active

development for quite a while. Many good pull requests were never merged

and the original project is missing some features which users can expect

from a modern password manager. Hence, we decided to fork KeePassX to

continue its development and provide you with everything you love about

KeePassX plus many new features and bugfixe

Hello again, my name is André Jaenisch, also known as Ryuno-Ki.

Last week I recorded my first episode for Hacker Public Radio, the

podcast you are listening to right now. This one is recorded on 15th May

2023. Again I'm publishing it under a Creative Commons Attribution

Share-Alike 4.0 International License.

Getting contacted

I was surprised to get mentioned on the Fediverse after submitting my

show. You can find me there at [email protected] (no dash, eight as

digit, link in the shownotes) in case you want to reach out to me.

I'm also delighted to have received an email even before my last

episode was airing. I was asked whether I am interested in recording an

episode on my experience with contributing to Hacker Public Radio for

the first time. So this is going to be the topic for today. As a warning

upfront: I have a reputation of overthinking stuff. I blame my

neurodiversity for it. That being said I'm positive that sharing my

thought process can help make the service better for everyone.

About recording software

I'm recording this episode again using Audacity. Now there is choice

about which software you can use for a podcast. Online based as well as

offline one. Audacity was in the news for sending analytics home.

However I couldn't find any indication in the settings for it (to

opt-out). The forks of the software weren't packaged up for Debian as

far as I could tell. Or perhaps they require an additional sources.list

entry, I don't know.

Before recording my very first podcast here I had only experience

with some video recording. Oftentimes done by the host but I also

prepared a few videos for an online course (which I couldn't publish

because life happened) and talks I gave during the pandemic years.

Learning about how to

podcast

As I often do when I enter a new subject, I went to the library and

grabbed some books to learn more. In particular I lended Podcasts by

Dirk Hildebrand. A small

book in German published at Haufe. I add a link in the

shownotes.

Reading through it I learned that I'm doing okay. It's really easy to

start a podcast as HPR promises! The thing I should spend some attention

on is keeping a consistent distance to the microphone, enable some level

of feedback during the recording so that I can listen to what is

recorded while speaking (using my gaming headset Logitech G230) and

prepare a script.

I don't have to think about designing images for the show or episode

because HPR will take care of that for me. It might be different if I

start my own podcast. Perhaps using Funkwhale or Castopod. Right now I'm not taking

steps towards that. Mainly because I need to rent some webspace first.

In my experience streaming media takes considerable amount of bandwidth.

Pair that with hosters that try hard to convince you to buy your domains

with them as well and the choice shrinks. I have my DNS provider

already, thank you very much.

Adapting lessons learned

I looked into how to do that in Audacity and I think the best I could

do for now is hitting on the microphone icon next to the meters in the

upper right of the interface and enable observation before I start

recording. Also leaving a little bit of time before and after the

recording allows me to cut keyboard clicks for starting and stopping the

recording. In HPR 3802 I also learned about skipping silences which is a

Effect in the Special category here. I hope I don't have pauses so long

that it warrants to truncate them.

My main thought about going with Audacity was post-processing

directly after the recording. I learned from my talks that I already

feel comfortable with a script in front of me. It gives me th
