So Bozeman to Bakken Oil fields is >400 miles. there and back is >800 miles.
800 miles @ 75MPH is 10h 40min. 800miles @ 85MPH is 9h 24min.

Savings of 1 hour 15 minutes, if you managed to keep average speed close to speed limit, which surprisingly is not horribly hard around that area. I live in South Dakota, and there really is not a problem. Almost no traffic and fairly flat and straight roads.

Which is why, when you do use tantalums, you use ones that are specced at twice the voltage you expect over them.

We've used tantalums in some telecom equipment we make, and except for about 5 spectacular failures (explosions, fireballs) on some early prototypes (because of wrong part numbers and such), we've never seen a failure in almost 7 years.

We could not have used electrolytic caps as they would not have survived as long.

BTW: reverse voltage an electrolyte, and witness the explosion (and foul smell) also.... Used to do that to scare people in electronics class.....
Of course, if we redesigned now, I'd probably change out some of the tantalums with ceramic caps.

My family has diesels in Norway (German Fords, 1.8L TDI). Latitude approximately Anchorage AK.
The cars have a secondary heat turbine that is used as a engine heater to get the engine to starting temperature in the morning, and to INCREASE the coolant temperature if it is too low.

The cool thing is that this turbine has its own timer so you basically have a mobile block heater with you at all times...
