You stop for lunch and a recharge.

Most people live in large cities. I suspect that Tesla can concede the rural Nevada market and still do very well.

I live in rural northern Wisconsin. There are 20 public charging stations within 50 miles of me according to the DoE.

I didn't intend to start a debate about the cost of health care. I just used it as an example of something that has changed so much since the thirties that it makes no sense to use it as a component of an estimate of inflation since then. The services you purchased did not exist in 1933.

You can't really adjust for inflation that far back. Too much has changed. We spend a large fraction of our incomes on things that did not exist in 1933. The average American travels by air frequently and owns a car that would have been competitive in major road races then. The majority of homes are...

I have never heard of septic pumps. Sounds horrible in Wisconsin we have something called the "Wisconsin Mound System". It's what you must use if your soil is judged inappropriate for a conventional drain field. Basically, they build a mound of sand and gravel and install the drain field in it so t...

Increasing the cutter diameter increases both the thickness and length of the chip so chip volume increases faster than diameter. This means that material removal rate increases with diameter at constant surface speed.

We're paying $1.22/gal for propane: $0.0000134/btu. Oil is $2.96/gal: $0.0000214/btu. Easy decision.

Does oil remain cheaper when you take efficiency into account?

It'll be even more fun after it gets hacked.

Harold writes: Propane is not a viable option, as it yields far less energy per gallon, and is priced accordingly. Not a bargain like it once was. Condensing propane furnaces can be more than 90% efficient, last longer, require less maintenace, and need no chimney. We contract for a year's supply (d...

The solution will keep pretty much forever.
