‘Engineering marvel’ found in Scottish attic ‘one of three in world’

A rare #Victorian engine, one of only three on earth, has been found by accident in an #Edinburgh attic.

“Remarkably, this engine is the second-oldest surviving Crossley four-stroke #engine in the world and the oldest in Europe.

“Only two other examples exist, the oldest is housed at the Henry Ford Museum in Michigan, USA, and another in Denmark.

"I wish I could believe you: the frustrating unreliability of some assessment research
T Hunt, S Jordan"

At the STACK25 conference earlier this month watched Sally Jordan present the keynote. I was very impressed and found this research paper from 2016. The co-author Tim Hunt is the main architect of the #Moodle #Quiz #engine and co-maintainer of the #STACK question type.

Conserving power is a theme, when living on a boat.

After a day of boating, you'd think it's OK to stop the engine right away. But sometimes it needs to keep running, to power electric devices that draw more than the boat's batteries and inverter can provide.

Some appliances draw a lot of electricity—a washing machine, iron, vacuum, toaster, microwave oven, electric chainsaw. I run these one at a time.

#OnThisDay Samuel Morey is issued the first U.S. patent for an internal-combustion #Engine (1826).

#BigBang theory proposed in Physical Review by Alpher, Bethe & Gamow (1948).

Another try of a procedural generated #engine sound, this time trying to catch an actual 'combustion' sound.

I think I'll split the project into:
engine sound lab (with some GUI around it)
the game (which uses sounds of the lab)
