JOHN GILKISON

John Gilkison is a professionally-trained astronomer who works for the New Mexico State University in Las Cruses. He chaired committee that wrote Las Cruces, NM Outdoor Lighting Ordinance in 1999, which was adopted in 2000. He incorporated the National Public Observatory (www.Astro-npo.org)in 1999. He is keenly interested in aerodynamic improvements in vehicles.

PhD Hubris

How having a PhD in Biology, Conservation Biology, Climate Science, or anything else really doesn't necessarily qualify you to speak on energy issues. Having actual expertise on energy issues is more important as without the prerequisite 10,000 hours of study you just won't know what you don't know.

Roof Racks, Boat Tails, and other Aerodynamic Oddities

A comparative analysis of five Coefficient of Drag Graphs (up to 100 mph) in Cd = 0.05 increments from Cd = 0.13 up to Cd = 0.33. This includes the Tesla Model 3 at Cd = 0.023 and a aerodynamically modified Tesla down to Cd = 0.179. Also included is an ideal body form of Cd = 0.13 and a Nissan Leaf body form at Cd = 0.28. Finally we have a Cd = 0.33 body form which is the shape of most cars on the market approximately.

Tesla Model 3 Aerodynamics Math Explained

How using three graphs of aerodynamic performance of Coefficient of drag body forms helped us outline the actual performance of a stock Tesla Model 3, a Model 3 with aero appliances to lower the drag to Cd = 0.179, and a ideal body form of Cd = 0.13. The actual range of modified Tesla Model 3 was an improvement from 310 miles to 370 miles

Our Tesla Model 3 with 440 miles of range blog was in error!

How mistakes were made mostly by me in projecting a range of 440 miles with an aerodynamically modified Tesla Model 3. The real range improvement is a more modest improvement to 350 miles at 70 mph. I will be publishing a new blog in a few days explaining the corrected math and the more realistic potential for range improvements with aerodynamics for a Tesla Model 3.

Tesla Model 3 with 440 miles of range (Mistaken Blog)

How some modest aerodynamic improvements to the Tesla Model 3 could dramatically improve its range at highway speeds. Enough in fact to give a Tesla Model 3 with a 310 mile stated range 440 miles of range at 75 mph. Range improvements like this would also apply to the Mid-Range and Short Range versions of the Tesla Model 3.

A Classic Ford Model T versus a Modern Electric Ford Model T

How swapping the engine and drive train of a classic Ford Model T could create a much better driving experience, save energy, and reduced emissions. This blog revisits Henry Ford's and Thomas Edison's idea of producing a electric Model T for the masses using modern technology and examines the benefits a modern electric drive train would bring to this classic car.

City of Las Cruces, NM EV Editorial

City of Las Cruces needs Electric Vehicles is the title of my editorial in an attempt to address misunderstandings by the City of Las Cruces, NM (CLC) about electric vehicles and concerns by their service department that they will not be able to service them. We have power point presentations ready to go if called on to do a presentation for city officials.
