My favourite Swedish Innovations

Så! I went home to Calgary, Canada almost two weeks ago! I had some time to clean up my “to do” list and some time to read.
I learned a lot about Sweden and its industrial heritage. I wanted to share with you some of my favourite Swedish innovations.
Can you add some more to dass list?
[Acknowledgment: I took screenshots of images from ebooks published by the Swedish Institute. They are great reads & food for thoughts.

Here we go:

I really don’t care about the rock drill… unless you are my dear friend Anu Sandhu from the Geological Engineering department.
But turbo <3
Turbo improves power and fuel economy = free money.
It has become very common on passenger cars in recent years as car manufacturers try to comply to greenhouse gas emission regulations. Also, due to spikes in oil prices turbo charger relieves consumer’s wallet.

I was really surprised (but also not surprised) to find out a Chalmerist (person who has studied in Chalmers University of Technology) invented the auto dark welding helmet.
Being a welder myself, the benefit auto dark helmets is comparable to the benefit brought-forth by the invention of the Automatic transmission! (yes, I can drive stick shift, just very agresively and a bit clutchy).

I guess this is the grandfather of GoPro cameras?
Göteborg has a Hasselblad art museum. I haven’t had the time to go yet. But I am looking forward to.
Any single ladies interested in cameras? No?

It is actually not terribly useful in a machine shop. It has undesirable backlash. You would need a fixed size wrench, or even better: a ratcheting wrench.
But at the end of the day, you MUST have one of these adjustable “monkey” wrench in your toolbox, in your car, or when you are working in the field.

When I was a teenager, my specialization was replacing skateboard wheel bearings. All my friends would come to me for their routine sk8board service.
I guess ball bearings have a special place in my heart.
I wish I had some SKF bearings then. My board would go as fast as Formula 1 cars.

It is -12 degrees Celsius today.  But I am still thankful it is not 10.4 Fahrenheit.
Screw propeller…Because being on a boat is not as glamours if you also had to paddle…

      Hi Hamid,

      Sweden is very different from the Middle East from a cultural and climate point of view. Nevertheless, it is a great country to study electrical engineering related work. There are many Swedish electrical engineering companies, such as Electrolux, ABB etc.

      Many graduates stay in Sweden after graduation. I don’t have the figures off the top of my head. Let’s say 30% or so. Many work in Sweden while others pursue PhD. Many Chalmers engineers graduate and work internationally, and that is what Chalmers is particularly proud of too.

      Best regards,
