Updates on the Army’s new combat rifle competition
Jeff LPH 3 sent me this article on the Army’s continuing selection process for a new personal rifle, to replace the M4/M16 and the M249 SAW. The gun that will replace both the M249 Squad Automatic Weapon and the M16/M4 rifle/carbine weapons — and add a new, widely distributed caliber to the U.S. military inventory […]
Army achieves new high-powered laser weapon breakthrough
Though we know he has a fetish for large things that go boom, the KoB sent in this tip on something that’s silent and invisible. Firing lasers from fighter jets while in combat, hitting enemy hypersonic missiles in space and incinerating enemy drones from armored combat vehicles are all missions intended for fast-emerging, now-in-development laser […]
So, How Much “Evil” Carbon Dioxide Do Electric Vehicles Cause?
In a previous article, I discussed how much fuel is actually “burned” (in terms of gasoline MPG) to support driving a popular and representative electric vehicle, the Chevy Bolt. Bottom line: that “100+ MPG equivalent” claim made by both the manufacturer and the EPA is pure . . . garbage. (smile) But another thought occurs: […]
Hunting Season Approaches
This video should entertain you nicely. If you ever find yourself in a primitive landscape (meaning outside a city) and think you’ll have to forage for food, you may want to take using an assist in spear-throwing to take down prey, as shown in this video. These guys are having far too much fun. It’s […]
“Rusty” Moon?
The blue areas in this composite image from the Moon Mineralogy Mapper (M3) aboard the Indian Space Research Organization’s Chandrayaan-1 orbiter show water concentrated at the Moon’s poles. Homing in on the spectra of rocks there, researcher found signs of hematite, a form of rust. Credit: ISRO/NASA/JPL-Caltech/Brown University/USGS Rust never sleeps. The moon is ‘rusting’ […]
So: What About Really Large EVs?
Intro Who says lightning never strikes twice? Last week, I wrote an article regarding the difficulty of charging a hypothetical all-electric US vehicle fleet with today’s electric grid. But as before, part of a comment to that article made by longtime TAH reader rgr769 caught my eye – and made me wonder: . . . […]
Air Force moves forward with study to make next Air Force One supersonic
Startup Exosonic, which has been conducting experiments and studies to design a supersonic passenger aircraft that does not produce the noxious boom. Currently the US and most other countries prohibit non-military supersonic flight over land because the boom created by the airplane’s shockwave is a nuisance at best on the ground and at worst knocks […]
So: If All US Vehicles Were Electric . . . Could We Charge Them?
Intro Last week, I wrote an article debunking the EPA’s blatantly misleading “108 MPG equivalent highway” claim for a particular electric vehicle, the 2020 Chevy Bolt. But part of a comment to that article made by longtime TAH reader rgr769 caught my eye – and made me wonder: . . . . If everyone in […]
