NexGen Weapons: Acoustic Weapons in Nature with [Video]

A variety of nonlethal acoustical weapons have been proposed and evaluated. Some of these are little more than fancy loud-speakers, while others involve more subtle or sophisticated processes and truely deserve the designation of acoustic weapon.

Acoustic weapons, also known as sonic or ultrasonic weapons, are devices that distract, harass, injure, or even kill a target using sound.

Simple high-intensity sound causes the inner ear to generate nerve impulses that register as sound. Since the inner ear also regulates spatial orientation, saturation of the inner ear by high-intensity sound may cause spatial disorientation. For example, loud music was used by American forces to drive Manual Norriega from the Vatican Embassy in Panama in 1990.

High-intensity low-frequency sound may cause other organs to resonate, causing a number of physiological results, possibly including death.Via: realitypod.com

World’s smallest Chevrolet 327 V8 engine

When this Chevy V8 engine was introduced back in 1962 it was the most powerful production small-block V8 untill LS6 came in 2001. 327 cubic engine was single-cam, natural aspirated. One of the petrolheads, Jim Moyer, expressed his respect to this engine by building its miniature — the 1/6th scale model that actually works. Jim spend a l

 

ot of time fabricating all the parts — block, head, crank, pistons, cam and others. The mini engine has spark ignition, oil system that are exactly like the ones from 327 muscle.

Even though it works quite well, this Chevrolet V8 mini engine still need improvements in order to run it longer: water-pump, carburetor, valve caps.
