Interesting list. I'd be interested with OilExhaustFilter or something that will greatly lessen if not will totally eliminate the smoke belching especially in older vehicles. The new Flowmaster muffler I ordered at 4WheelOnline came for the Cherokee and something that will greatly control the oil in the exhaust system should be helpful.

Years ago it occurred to me that a vehicle could use electromagnetic suspension dampers (commonly misnamed shock absorbers) which could convert the movement of the suspension into electrical energy, partially recharging the battery in an electric vehicle, at the same time providing the damping effect currently provided by hydraulics. I read somewhere not long ago that some development is taking place now. Does anyone think this might be useful?

It might work, given that regenerative braking also works on the principle of "turn some waste energy back into useful energy".
Once a technology like this even on a small-scale charging system has been developed, more concept will follow.

With so much conflict among countries for decades, the chance is very slim..

Interesting experiment, I wonder if your mind has become habituated to the music just like a constant background sound can be filtered out. Same happens with other stimuli eg nerve ends on skin.

You might be interested in this study http://icmpc-escom2012.web.auth.gr/sites/default/files/papers/1124_Proc.pdf by folks at Goldsmiths.

That's an interesting experiment.

Can it hit a target?

That would depend on a few factors, including the shooter's aim.  I suspect there is a greater chance of success on film than in real life.

Most of the things in the films and movies are exaggerated. Hitting the target is still possible but less chance and impact compared to a gun fired by a man on the ground.

Three Parts Of the Night Sky


* 6a0105371bb32c970b01bb09815d2e970d.jpg (140.76 kB . 1500x994 - viewed 34622 times)

Photographer: Marcelo Zurita
Summary Authors: Marcelo Zurita; Jim Foster


In this one photo I was able to capture cloud-to-cloud lightning (at bottom), a starry sky above the storm clouds and a dazzling meteor. It was taken from a rural area in Brazil's eastern-most state of Paraiba. My attention was actually on the distant storm on the horizon but as I snapped the shutter a meteor passed through the field of view. The lightning is at an altitude of perhaps 40,000 ft (12,192 m); the meteor is streaking by 70 mi (112 km) or so above the Earth's surface; the brightest star in the frame, Menkar (at upper right center in the constellation of Cetus), lies approximately 250 light years from our solar system.

Photo Details: Camera Model: NIKON D5100; Focal Length: 14.0mm (35mm equivalent: 21mm); Aperture: ƒ/5.0; Exposure Time: 30.000 s; ISO equiv: 800; Software: GIMP 2.8.14.



Great shot!

General Science / Re: How can we measure stress?

There are people who are stressed yet still have high energy to do other things, thus doesn't get affected much by stress.
