Here's my own list of woodworking things I want to know vs the things I have mastered:

only in the softback editionI want to know if the book on the left works as a Slinky.
I was wondering about the economy of heating water with petrol/gasoline to make steam, to drive the car v burning petrol/gasoline directly to drive the car.
The maximum possible efficiency is if I remember about 60%, surprisingly high, better than a propeller for example, however steam locomotives rarely achieved more than about 8%. Our physics teacher at school who believed in teaching things we might actually benefit from as well as the syllabus had us do a heat audit on a Mamod stationary engine, it's a long time ago but I think we got just over 1%.It'd be interesting to see the economy comparison - if I remember correctly petrol engines are only about 30% efficient, so this might well be the more efficient approach.
Things Artie doesn't know about.
Thanks,Its fuel consumption, burning a variety of fuels (often kerosene), was competitive with automobiles of the day,
No No NO! The boiler will explode and kill people, much better to pump Lead into the air for about a century.I have always wanted one of these, and when I go on about it to others they look at me blankly. l am not the only geek here lol! Hurrah!
600,000 mile between major service overhaul if I remember right…no clutch, no gearbox, silent…
The 1924 model Doble Series E steam car could run for 1,500 miles (2,400 km) before its 24-gallon water tank needed to be refilled; even in freezing weather, it could be started from cold and move off within 30 seconds, and once fully warmed could be relied upon to reach speeds in excess of 90 miles per hour (140 km/h). In recent years Doble cars have been run at speeds approaching 120 mph (190 km/h), this without the benefits of streamlining, and a stripped-down version of the Series E accelerated from 0 – 75 mph (121 km/h) in 10 seconds. Its fuel consumption, burning a variety of fuels (often kerosene), was competitive with automobiles of the day, and its ability to run in eerie silence apart from wind noise gave it a distinct edge. At 70 mph (110 km/h), there was little noticeable vibration, with the engine turning at around 900 rpm. (Wikipedia)
