The Anonymous Widower

Big London Hospital Was Close To Running Out Of Oxygen

The title of this post is the same as this article on  The Times.

With COVID-19 and all those ventilators and CPAP devices, this sounds like a tragedy about to unfold.

I also remembered a story told to me by a friend, who used to be the Chief Pharmacist at a London hospital.

Oxygen was one of their problems, as the tanks were in a small yard with gates opening on to a busy street, about two hundred metres, away from the hospital.

The problem was that illegal parkers would block the gates, so that delivery couldn’t be made.

Knowing my physics and the reliability of deliveries in parts of London, I thought on-site electrolysis might be a better idea. So I consulted my bible.

There on page 760, it is all described how water can be split into two molecules of hydrogen and one of oxygen by electrolysis.

ITM Power are the experts on electrolysis, so I sent them an e-mail and asked if they could make an electrolyser, that produced oxygen instead of hydrogen.

The reply came swiftly and confirmed, that they could make an electrolyser that supplied oxygen. They also said, that the oxygen was of a high purity.

Just Connect Electricity And Tap Water

All these electrolysers would need is supplies of electricity and tap water to create hydrogen and/or oxygen.

No trucks would be needed to deliver tonnes of liquid gases, which can be rather dangerous to move around city streets.

ITM Power’s hydrogen electrolysers are starting to appear in filling stations, so they can refuel hydrogen-powered vehicles.

One could be installed in a hospital to provide a continuous stream of pure oxygen, which could be piped into the current oxygen delivery system.

What To Do With The Hydrogen

The hydrogen electrolysers produce oxygen as a by-product, which I suspect is just vented to the atmosphere!

But you can’t vent large amounts of hydrogen to the atmosphere, as it is an inflammable gas!

However, you could do either of the following options.

  1. Connect it to a hydrogen fuel pump to refuel hydrogen vehicles.
  2. Inject the hydrogen into the gas main, as is regularly done with hydrogen produced by surplus renewable electricity.

I prefer the first option, as it could mean that health-care could start to use hydrogen-powered ambulances, that are zero carbon and pollution-free.

Perhaps not an appropriate saying for the industry, but it would genuinely kill two birds with one stone.

The Innovation Must Go On

This is a snippet I found on this news round-up on Rail Business UK.

Network Rail has issued a request for information on innovative techniques for undertaking tunnel renewals and enlargement while minimising blockades. NR said it manages 693 tunnels that are typically 150 years old; these require different and increasing levels of maintenance and renewal, but the growth of traffic means there is less access for maintenance.

Someone in Network Rail has got the engineering envelopes out again and is doing their thinking at home under lockdown, rather than in a real ale hostelry.

Companies and other organisations, should use COVID-19 as an opportunity to innovate.

Imagine the unthinkable and the downright bonkers, so long as it’s legal!

Think loony! You know it makes sense!

Zopa And COVID-19

As regular readers of this blog will know, I invest my spare savings in the peer-to-peer lender Zopa.

I have a feeling, from my experience of reading the statistics of my lending on the site, that money is slow to be lent out!

But there are people out there, even in these insecure times, who have a guaranteed cash-flow and a good credit rating.

And some of these may need a loan to perhaps replace a car, that has expired and they need to get to their essential job or to furnish a spare room as a home office or schoolroom.

If I needed a sensible loan, which I don’t, I’d check out Zopa.

Lockdown And INR Testing

I am on Warfarin and have to be tested regularly for my INR.

I have been doing it for at least seven years now and know that if I test twice a week and take four milligrams of the drug my INR stays well within limits.

This is a testing regime, which fits well with the COVID-19 lockdown, that I’m currently enforcing on myself!
