Debunked: SUBBE electrolysis diving thingy


A new scam pitching for the burgeoning "impossible underwater breathing device" market:

Easily debunked in two main areas: chemistry and power requirements. Also, their imagery is lazy photoshop fakery.

Chemical debunk:

Electrolysis of seawater produces chlorine gas, sodium hydroxide and hydrogen - not oxygen.
Uh, also:
Edit to add: The products of the electrolysis of seawater are either explosive, corrosive, poisonous or more than one of the above, so you really don't want them anywhere near your lungs, or even strapped to your back.

To produce oxygen from electrolysis, you need fresh water. Subbe does not mention if or how they are going to purify the seawater before electrolysis, nor what happens to the explosive Hydrogen gas that would also be produced by the resulting process on the desalinated water.

Anyone with more chemistry than me, feel free to expand on this.

Power requirements debunk:

This comes back to that pesky respiratory physiology. An average human requires somewhere between 15-20 litres of breathing gas passing through their lungs per minute while diving in order to maintain respiration and flush carbon dioxide from the body.

Even assuming Subbe has somehow invented a revolutionary method of electrolysing oxygen from salt water, it takes a theoretical minimum of 12,749 joules to create a litre of hydrogen gas H2 at perfect efficiency, double that for a litre of oxygen gas O2 (as water has two hydrogen atoms for each oxygen atom).

So absolute minimum theoretical power requirements would be around 400,000 joules per minute, or 33,750,000 joules for the claimed 90-minute run time. This is nearly 9.4 kWh. Real world power requirements would be much higher. This doesn't include the power requirements of desalinating and purifying the water before electolysis.

For comparison, the Tesla powerwall ( has a 6.4KWh capacity and weighs 97kg, so you'd need at least two of those strapped to you to power this device. A little larger than the 3kg total weight claimed for the Subbe.

Edit to add: Nuclear submarines do actually producine oxygen from electrolysis, by purifying the seawater first - but then they do have the benefit of a nuclear reactor on board to supply the power required...

Fake imagery:

The imagery showing the device 'in use' is crude photoshoppery of pictures taken from the internet. Example; this one:

is a minimally modified version of this:

which can be found on the first page of a Google image search for "scuba diver". Originals for other Subbe images can likewise be easily found by Google reverse image search.

As per many other 'impossible device' crowd funding scams, if the creators have actually somehow solved the technical challenges creating their device they would be making billions selling their multiple revolutionary inventions to governments and industry, not gadgets to snorkelers.

So completely safe then :eek:


I kinda thought that it was too obvious to put in the original post, but maybe I should go back to spell out that, all of these things, you REALLY don't want to either breathe them, or even have them strapped to your back in a little rendered plastic CGI thingy.

Science trivia note: Water is the 'ash' produced from burning hydrogen. Which is why water is effectively inflammable - it is already burnt. :cool:


Campaign is now locked "under review by the trust and safety team" - so maybe, just maybe, the crowdfunding industry is learning. (Or, more cynically, the campaign hadn't attracted enough funding to earn itself a higher level of immunity.)
