What type of materials?

Elizabeth, what types of materials are these? The article says they're a new class, but does that mean metals, plastics, composites, nanocomposites, or something else?

I think William raised a good point. If these artillery shells are 5x more lethal, does that mean 5x the explosive force? Whatever the percentage or factor, it's greater explosive force which means they're likely to be more dangerous to store, as well as to deploy.

Reactive material artillery shells.

I would be concerned about the stability of the materials under various conditions. Unstable ordinance just sounds like it would be really unpleasant. The reason for this concern is that it seems to me that materials that are able to explode would be a bit more reactive, and thus less likely to be completely stable. But perhaps there is another answer.

I agree about the emotional response--that's why I prefer "x times" to "x%."

Like the Ironman Ammo Carrier (above), it should ease the burden of material needed to wage war.

Jhankwitz, you are right. Every year government is spending billion of USD for military R&D inorder to strengthen the national security and weapon systems. I think the same technology can also be use for common peoples benefit also. For example, the light weight materials using in space craft can be used for making artificial limbs etc.

Thanks Ann.  I understand the math.  I was just making an observation about the emotional response to "500 percent more lethal". 

Mining work is a possibility but, as you mentioned, I don't see any advantage over current technology for that particular industry.

I agree, Ann. I can't imagine any non-military applications for this. It's designed, not just to explode, but to wreac havoc when it does.

500 percent more lethal just means 5x more lethal. Although that's a lot, considering the fragments will release both kinetic and chemical energy. The only non-military use I can imagine is for the other apps of explosives, such as mining work, although I don't see what chemical energy will bring to that effort. It would be interesting to know what chemicals are involved.

It's unfortunate that the results of this research will be limited to military applications.  It would be nice if it could spill over into non-military applications.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition.

Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
