Motorcycle / Bicycle Gyroscopic Effects
(c) Copyright 2013 David Dilworth Gyroscopic effects are one of the few physics principles that are not intuitive to me. I’ve studied them and used them for decades, yet when I spin a bicycle wheel holding it by the axle … Continue reading
News: New World Sailing Speed Record by Paul Larsen and Vestas SailRocket 55 knots (63 mph, and momentarily hits 78 mph unofficially) !
(November 18, 2012: Namibia, Africa) Vestas Sailrocket 2 piloted by project leader Paul Larsen traveled at more than 55.32 knots (exceeding 60 mph and 100 kph) over a nautical mile course on Walvis Bay. For a few moments during the … Continue reading

Can you Shoot an Arrow Backwards – into Space ?
You might have heard about a secretive space flight effort in the wilds of Texas that sustained an unfortunate crash recently. That was the “Blue Origin” project. (http://www.blueorigin.com/) The flight was aborted by “a flight instability” as the team called … Continue reading

How Japan Can Stop Dumping Radioactive Water in Our Ocean
“The release of radioactivity from Fukushima–both as atmospheric fallout and direct discharges to the ocean–represents the largest accidental release of radiation to the ocean in history,” according to a National Science Foundation synopsis of a study. “As of February 2012, … Continue reading

Preventing Oil-Tanker Spills With Proven Aircraft Technology
Preventing Oil-Tanker Spills With Aircraft Technology (c) Copyright 1990-2005 David Dilworth This is a concept for an inexpensive, but not free, lunch. Converting proven technology can dramatically reduce the serious harms from oil tanker spills and their fires and lower … Continue reading

Replace Car Batteries Instantly – No Charge
A couple of weeks ago I saw electric racing motorcycles at Laguna Seca. I was shocked (sorry) at how quick they were. In the medium speed section of the course, a few bikes were approaching the speed of the fastest … Continue reading

Understanding of Two Fundamental Physics Phenomena Improved Dramatically
Here are two articles on landmark research explaining how we mis-understood two static physics phenomena prior to 2011: Static Friction and Static Electricity. 1. Static Friction “How Earthquakes Can Be Predicted: Researchers Reveal New Means” http://www.sciencedaily.com/releases/2010/11/101130100524.htm These researchers found the … Continue reading
