This has been around a while. The army invented it for vehilce combat training. Blue rounds. Now it it used for many things. More commonly called frangible, but not completely the same as what police use. Also been called 10% rounds. When they hit something hard like a tree or rock they pretty much turn to powder.ecologically friendly non-lead ammuntion

Modern soldiers are so dependent on electronics that they wind up carrying stupendous loads of batteries into the field. Portable means of recharging is one area of active military interest. Leaves more carrying capacity for ammo.
Once you clobber a place, you wind up having to rebuild it. As Colin Powell said, "You break it, you bought it." So reconstruct with renewables. Think about it ... get Iraq, which can export oil but does not have much refinery capacity, set up with servicable but meager energy, forever limited. With luck they learn to make do with it rather than exploiting their own reserves. Should keep them in check for a generation, at least.

If I would a soldier I would select the first and the second - categorically not. Nevertheless I doubt in usefulness of such devices as effectiveness of those is highly depended on weather conditions.ladajo wrote:The flexible panels are key, when in movement they are rolled up and pack with minimal weight. Same with a small wind turbine. (useful up in the mountains).
E.g. you need to charge battery now and Sun is covered by clouds. You have 2-3 very advanced Javelin missiles, see the hostile tanks and can not fire.
And are flexible solar panels available and accepted by US Forces (Ground or Marines)? Advantage?
This device has parameters http://www.protonex.com/downloads/produ ... 2-1110.pdf :
Wehight (mass) - 16kg
Continious output power - 300W
Fuel consumption - 0.45 l/h (ten hours - 4.5 l =~3.5kg+may be 0,5kg canister)
So, device+fuel enough for 10 hours wehghs 20 kg and as I understand can be easily be carried by back-bag
Now let's compare if you have any data.
I would give one parameter:
Dependency on weather - yes
Joeseph,
I am not saying Fuel Cells are not useful, they certainly are. I am saying that one should adopt a multi-path approach to the problem and use what is needed. The question on the table is what is more effective for an extended remote primarily foot mobile mission? And the answer is based in the traditional approach of lots of one shot batteries and pre-staged caches, or less one shot batteries (size and weight) replaced by more rechargables and recharging methods. When you are on foot and far away it is all about first weight and second volume (although they tie closely). To answer your question, both Marines, Army and SOF use the systems discussed. And at the end of the day it is about what works best for where, and what works best is defined by meeting mission needs (for that mission) as well as increasing mobility and effectiveness.
On one mission it may be better to take a fuel cell, but on another where you could be limited in liquid resupply or access, they may opt for compact solar or compact wind. Or some combination.

I am really interested what they do use? Not for discussion but for only my knowledge.ladajo wrote:On one mission it may be better to take a fuel cell, but on another where you could be limited in liquid resupply or access, they may opt for compact solar or compact wind. Or some combination.
Producing company and model?
As for example I know that they use Trijicon sights, M4 assault rifles of Colt, M110 rifle of (forgot), m249 machine gun of FN USA, M203 underbarrel grenade launcher of Colt, etc.
As I recall, bismuth exhibits inferior ballistics due to its somewhat lower density vs. lead.MSimon wrote:Non-toxic lethal devices.

There is another option generally considered non-toxic:

anti
I haven't researched this in detail; those are just early results from a Google search...
For Solar, this is a 40x60 ft example of what is in use. It puts out 2KW.
There are other variants.

The first is similar to sail - roomy but light in weight. Thank you - I did not know.
Regarding wind turbines, as I understand you are proposing me googling.
But I am asking a little bit different: is US Army or Marines considering (examining) wind turbines or solar panels for acceptation them officially as military equipment?
As I know many examined and non-accepted types of weapons or equipment.
