Rest in peace bro I love you man

Robert You really should have EU funding for a school series of videos for the young and old  minds out there in my 58 years you are by far the best teacher I have ever had bar none cheers

I remenber going into secondary school. The first thing we did in science class was make water rockets. This was followed closly be actual small rockets (basically fireworks). We did everything from model aircraft to a small distillation unit to electro plating and making hydrogen. It's because of my science teacher I did a degree in mechanical engineering.
Thank you Mr Ford. 😊

I really hope i bump into this guy someday just to shake his hand and tell him he's awesome. Keep up the good work and never change.

I would love to see your post apocalypse home electrical grid choice. Batteries or harvesters etc,  generators, storage, distribution etc. Your choice. What would you do?

We've gotten a wealth of knowledge from Rob over the years. Probably the last year was focused on 3D printing stuff which didn't patticily grab me but Rob definitely had a passion for. I watched most of the 3D stuff anyway for loyalty sake or suchlike but I don't think I understood much.
  Valé Robert.

Robert, as folk are commenting on the audio quality I thought I suggest some solutions to consider..

1. Davinci Resolve Pro has a couple of useful functions that help isolate human voice and also level audio

2. Also might be worth investing in a decent audio recorder with a lapel mic to get better audio quality. Easy to sync with your video. Eg: Tascam DR-10L

I use both for my own instructional videos and it makes a massive difference.

Appreciate it’s a budget thing but thought I’d mention it rather than the troll snark.

Now you have rust all over your lab. :-)))

I was lucky enough to meet Rob today at the beach!! Made my day!!
Great video as always sir, shame about the sound quality but the content was A star ⭐️

You are missed Robert! RIP ❤

God man ... RIP Robert ❤

Great Work Earthling

Blessings From Aberystwyth , Wales ❤

my cousin just graduated chem in air batteries, so he'll likely be talking about it!

Really excellent information from a much missed wonderful man.

As a chemist my gut says this will work with an old aluminium can. But I can't be bothered to check....

I find it strange watching Roberts videos knowing he is no longer with us. RIP

Oh, you just brought back some awesome memories from long ago! When i was but 12-13 years old, I made (found plans in some book or other) a Zinc-air cell. If memory serves, utilizing black Iron oxide as catalyst and incorporating a continuous fueling (well, slowly pulling the Zinc foil and separator along) system. I suppose that makes it a fuel cell?
I was invited to present it to a university class (on a different topic) which I was "informally" (read, just walked in, sat down and started taking notes) auditing.
Quite the terrifying thrill for that young boy but I believe the Prof. wanted to make an example of the curious, awkward and desperately bold chap.

R.I.P

Want to make a super high current version? Use steel wool with rust as the anode with a stainless steel or nickel alloy current collector. For the electrolyte use sodium or potassium hydroxide solution. Coat a fine silver plated screen with a mix of graphite, activated charcoal, silver and MnO2. Best to rapidly stir a slurry of the carbon and silver nitrate, then add a bit of KOh with heating, Next add kMnO4 then add hydrogen peroxide to add the MnO2 to it and vacuum filter. Add fresh KOH to it and scrape into the screen. Make a sandwich of 2 cathode and 1 anode plate and wrap it all in tyvek material. Gives about 1.3V but can output several amps and can be recharged. ❤

Fascinating! I really enjoy sharing in your excitement. Thank you for such eye opening content!
