APRIL 5TH, 2016 Day I built the Pendulum Type 1, which
     resembles perpetual motion. On YouTube

MARCH 18, 2016  
Day I proved an object could return to the
same altitude with momentum. YouTube link

FEBRUARY 14, 2016 Day I was granted membership to PESWiki.

DECEMBER 15th, 2015 Day I proved a lever could lift its
fulcrum with minimal effort. YouTube link

NOVEMBER 7, 2015 Day I tweeted my most important perpetual
motion tweet on (if we ignore Finsrud).

JULY 3, 2014  Day I discovered that objects can roll upwards.
Based on an earlier experiment with the Coquette (June 29,
2014). As a result, I created a diagram of the
"Escher Machine".

My First Successful Over-Unity Experiment
(AcademicRoom.Com) or
view it at my blog
If a device can go up and then down from a position of rest, and
all parts return to their original positions, then there is theoretical
over-unity. This device meets the criteria.
The diagram shows
how to turn the over-unity device into a perpetual motion

APRIL 26TH, 2009  Day I Invented 50 Devices
These devices contributed significantly to my working tools,
but so far as I know none of them have joined my online
collection. I cite many flaws.

APRIL 16TH Day in which I have invented Five Devices more
than once, first in 2007. One of these was the Coquette.

APRIL 2ND, 2007
Day I found evidence that the Tilt Motor could work
With near horizontal slope, leverage can extend slope.
Confirmed once, denied twice. Confirmation was with a level.

Day I seemed to prove an unbalanced wheel, the "Principled
     Asymmetry". The device seems to rotate more easily in one
     direction than another.

OCTOBER 30TH, 2006
Day I invented the Tilt Motor, and time-traveled back to the
     morning of the same day. The Tilt Motor is the ingenious
     concept of a horizontal wheel, operated by levers.

CIRCA MARCH 2005 A visit to Mystic Aquarium resulted
     in an encounter with a 'Marble Rally' game, inspiring
      thoughts about leverage with supporting slope.
     However, the actual device concept was not
     formulated until years later.

 In 2014 the famous Visual Education Project
 was inspired by some of my designs, and
 an article appeared at
 introducing three of my designs (the Tilt Motor,
 the Motive Mass Machine or MMM, and the
 Escher Machine).

 Since then I have come across some possibly
 even better designs, including the above maybe
 confirmation of the
Pendulum 1, and a spat of
 6 or more designs I call the
Not-If-But-When Machines'.

 My (not yet famous, perhaps) poem reads:

While they were floundering,
         I was pondering:
         "No more wandering through the dark tunnels
         Of grim determination...
         For no, it is time to grow
         In a thousand folded folds
         For which we need an infinite fuel!"

 My most popular experiment can be found at:
Successful Over-Unity Experiment 1, which has over
 2000 views on YouTube.
