PIE 2.0 All Pretty — Before Being Worked Hard, Out in the Real World <\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

I find that it has been tough to get busy and simply do what needs to be done lately. The PIE 2.0 has had to take a \u201cback seat\u201d to far more important family business, but I finally did get some time to finish up some \u201creal world\u201d testing at a reasonable speed of 55 MPH (88 KPH). It is not an easy thing to find a \u201cflat\u201d stretch of highway in the Northeastern United States (about 350 miles inland), so I have made do with a straight stretch with only some small rolling hills and with an estimated elevation rise from start to finish of approximately 15-20 feet (not verified with altimeter).<\/span><\/p>\n

<\/o:p><\/p>\n

As before, measurements are taken and only considered valid if measured values are repetitively similar.<\/o:p><\/p>\n

I was able to bring the PIE 2.0 up to slightly over 120 RPMs and test before it broke this last time and left a weight laying in the truck bed.<\/o:p><\/p>\n

<\/div>\n

So, here is a simplified recap of test results obtained on this test roadway at 55 mph withal accessories off and auto trans in 3 (not OD) to help keep it from shifting during the test:<\/o:p><\/p>\n

Running at 90 to 100 RPMs, engine load reduction was 6%.<\/b><\/o:p><\/p>\n

Running at 105 to 108 RPMs, engine load reduction was 8%.<\/b><\/o:p><\/p>\n

Running at 120 to 122 RPMs, engine load reduction was 13%.<\/u><\/b><\/o:p><\/p>\n

At 120 to 122 RPMs the \u201cfeel\u201d of forward thrust was much smoother although overall vibration was fairly pronounced.<\/o:p><\/p>\n

During the final test run two things happened causing testing to end for the day. <\/o:p><\/p>\n

First one of the weights found its way off the planet gear and into the bed of the test truck.<\/o:p><\/p>\n

<\/a><\/div>\n
<\/div>\n

Second, the drill motor overheated, slowed and finally stopped until it cooled off. <\/span><\/p>\n

  <\/a><\/p>\n

Note that the picture on the left shows an added piece of metal welded to the frame to keep the drill bracket from shifting position which was a key problem with the drill’s chuck “slipping” on the shaft.<\/i><\/p>\n

Results:<\/b> The PIE 2.0 design is a viable Hybrid design!  <\/span>It definitely needs a better build (no prototype temporary components), a better motor, and a sound deadening enclosure, but this is a repeatable, working design that can be built on a budget!<\/o:p><\/p>\n

Conclusion of This Round of On-Road Testing:<\/b> I am way past encouraged and I am soooo ready to build the next gen \u201cPieTech\u201d design. There are others also working on their own versions of a PIE so I really do not know what version my next will be, but I know it will be able to run at more than 120 RPMs!!!<\/o:p><\/p>\n

The PIE 2.0 is, overall, a resounding success and it will be repaired. I do want to perform some \u201cself-propulsion\u201d demos with it before I consider it finished. I am hoping to video it on wheels and on water. I have had 1 request for a pendulum test, I do not consider it as accurate since it is too easy to skew the outcome by simply moving the center of gravity, so I have not seriously considered it yet.<\/o:p><\/p>\n","protected":false},"excerpt":{"rendered":"
