Long Coal Trains
Even traveling at 60 mph it took us 0.9 miles to pass the complete length of a train moving at a moderate speed in the opposite direction. We then passed another train which was stopped. It was 1.4 miles long with 135 full coal hopper cars and 3 engines.
On several occasions, both on commercial and private flights, we have seen the circular fields of crops in Nebraska. Now traveling this same region we see that these are 1 mile square fields being irrigated by ½ mile long radial pipes rotating 360 degrees across the fields.
Mathematics Challenge: What percent of each field is not irrigated and is therefore unproductive?
Question: How could these fields be irrigated to reduce this loss? If your answer is 1 mile linear pipes, why isn’t it commonly done this way?
On to Wyoming
We are now hiking with friends Pat and Dick Gritman in the spectacular Teton Mountains near Jackson Hole, WY. Great sunny skies, cool morning but hot afternoons. More about this in our next posting.
