Speed! Power! Performance! Humans have always wanted more, more,
more of all three from developing technology, and they’ve
gotten what they wished for tremendous advances in machines and
methods that have, in some instances, nearly removed the farmer
from the farming.

But they say that, on any journey to the future, you can’t
know where you’re going unless you know where you’ve been.
That’s what makes the engine shows so important; they put us
back in touch, literally, with what it took, and what it means, to
labor to feed a nation.

These few months are filled with lots of shows across the land.
Don’t miss the opportunity to support the efforts of those who,
like yourselves, are working to remind us where we’ve come
from.

And don’t miss the chance to share what you find out there
with fellow IMA readers drop us a line if you find
something, or someone, interesting! Now, on to our letters.

We hear this from GREGORY HOESLI, 717 W. South Street, Salina,
Kansas 67401-4063, ‘In the May/June issue, Pete LaBelle wonders
if the comparison between steam engines and gasoline (or diesel)
engines can be made more clear. Both in theory and in fact, the
modern gas engines do indeed develop much more power than the steam
tractors on the basis of size, and the two clues as to why this
makes sense come from the differing nature of the two types of
engines. The steam engine uses wood or coal burned externally to
power the engine itself, whereas the gas engine burns its fuel
internally, and much more efficiently and that gasoline has about
60% to 100% more heat value per pound than coal. Also, the speed of
the steam engine is so slow by comparison. Remember that
‘power’ is ‘work’ (such as torque in foot-pounds)
per unit of time, and even though the steam engine has a power
stroke twice per revolution while the gas four-cycle engine has one
every other revolution, the gas engine is running some ten times
faster. That is why the power comes in such a small package. It is
interesting to note that the maximum torque of a steam engine is at
zero rpm but a gas engine must be running at a good clip to get its
maximum torque. In fact, the gas engine has no power at zero rpm.
For comparison, both engines’ calculated power are derived
from:
