Students Design ‘Mitt’ Prosthetic Limb For Children

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

This was the good news story of the day, which started with these two paragraphs.

Even the most up-to-date prosthetic limbs can often be too heavy, or hard for young children to use with ease.

But now, a group of Imperial College engineering students has created a new, lighter one.

There is a video in the BBC article, which shows how it works.

  • It looks like it doesn’t have any power, so there are no heavy batteries.
  • Tools are attached by a powerful magnet.
  • As the name suggests, it is worn like a glove.
  • Judging by the look on the little girl’s face, as she used it to do simple tasks, it has found a satisfied customer!

What puzzles me, is that it is such a simple idea, that it hasn’t been thought off before.

Could The Mitt Have Other Applications?

I have a feeling it could.

I recently cut the back of my hand badly.

The picture shows it soon afterwards.

I don’t work or do many dirty tasks around the house, but could the students use their design principles for someone, who has perhaps damaged their hand and needs some protection.

This second picture shows how well it healed in the end.

I think the principle behind the Mitt has legs.

Sweden’s Grand Plan To Make Zero-Carbon Steel

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

It adds a lot of colour and background to Sweden’s plan to make zero-carbon stell using a process called HYBRIT, that I wrote about in Funding Award to Supply An 8MW Electrolyser and is illustrated in this infographic.

The amount of hydrogen needed is large as this paragraph from the Telegraph article says.

HYBRIT’s demonstration plant, for which an investment decision is due in 2022, will require 400MW of power just for the electrolysers to make the hydrogen. Sweden’s largest existing wind farm, Björkhöjden, produces just 288MW. Then to store the hydrogen, Vattenfall plans to build 120,000 m3 of lined underground storage, enough to store 100GWh worth of the gas.

Will they procure the electrolysers from the UK’s experts in the field; iTM Power? This innovative company is building the world’s largest electrolyser factory in Rotherham, which will be able to produce a GW of electrolysers in a year.

Conclusion

This well-written article in the Telegraph explains a lot about steel produced using hydrogen instead of coal.

Sweden has a lot of advantages at Lulea to create steel.

  • The iron ore is mined locally.
  • Sweden has ninety percent of Europe’s iron ore.
  • Ships can sail to Lulea, which is at the top of the Baltic.
  • There is gigawatts of zero-carbon electricity from the River Lule.
  • They can build wind farms in the area, which has a low population.

It does look that they might export the iron ore as sponge iron, which can then be processed directly into steel products using electric arc furnaces.

Cup Of Tea Brightens The Day And The Mind

The title of this post, is the same as that of this press release from Newcastle University.

This is the introductory paragraph.

If you’re enjoying a cup of tea and mince pie this festive season, you may be refreshing more than your palate, as research shows a good brew improves the attention span in those over 85-years-old.

I find this research interesting, mainly because I drink tea in large quantities, at a rate of at least six mugs a day.

But then my family seems to have an unusual drink problem.

  • I drink decaffinated builders tea and usually in a day, I’ll also drink two bottles of 0.5 % alcohol beer from Adnams and other soft drinks too!
  • My father was the same except that he would have a pint of Adnams a couple of times a week.
  • But his father drunk so much, he became an alcoholic and died at forty, well before I was born.
  • I also tend to have a mug of tea before I go to bed.
  • I’ve always preferred tea to coffee.
  • My fifty-year-old son is teetotal, but seems to drink a lot of tea and soft drinks.

As both my father and myself share a skin problem, which is probably related to coelic disease. I think, I sweat a lot of water through my skin, so I need to keep topping it up.

Conclusion

After reading the report from Newcastle University, I think I’ll keep drinking the tea.

My First Request For Music On The Radio Was Successful

At seventy-three, I’d never askd for a tune to be played on the radio.

The presenter on Radio 5 Live, asked listeners to suggest a track, that would be suitable for the times.

So, I texted in.

Surely, the best track for these times is We’ve gotta get out of this place, by the Animals!

I was very surprised, when they played it!

As many do, I’ve got the name of the song wrong, as it’s actually We Gotta Get Out of This Place.

I certainly saw The Animals, at least twice.

The first time was when I was about sixteen, at the Regal Edmonton, where they topped the bill, with the Nashville Teens being the second group. I can remember Eric Burdon singing House Of The Rising Sun, highlighted by a red spotlight.

I also saw them at Cook’s Ferry Inn, when they chose a replacement for Alan Price and I may have seen them whilst at Liverpool University.

Those were the days!
