The U.S. Army Edgewood Chemical Biological Center is leading the charge to replace it with one of four options, each of which uses a unique composition: First, a zinc-free version that similar to the good ol ; grenade currently being used, except without all that acrid toxic smoke. The second uses magnesium and aluminum to create a dense white cloud of metal oxides, which doesn ;t sound all that great either. The third is based on lith

The fourth in particular sounds crazy: Because none of its ingredients are water-soluble, it wouldn ;t contaminate the water supply. Instead, it uses a plastic matrix to encapsulate the chlorine. Here how Kit Up! explains it: Because the rest of the plastic matrix is carbon, the smoke is filled with fine carbon particles giving a dark gray to black color. This unusual as the best smoke compositions are

So while none of these options sounds particularly great for either soldiers or the environment, each of them is using newer chemical technology to, at the very least, produce smoke that less harmful to humans.

Other design variations are looking into using hydrogen or methane-based fuel cells as potential green power supplies. The Volt, however, appears to be the most practical system to emerge from Boeing research, functioning much like the Chevy Volt or the plug-in Prius do. Every time it at the gate, the Volt will draw
stanley cup electricity from the airport power grid, charging an array of batteries stored in the belly of the plane. Dual-turbine engines would be powered by traditional jet fuel for takeoff, but once the Volt reaches cruising altitude, the system will switch over to electrical power for the majority of the flight. Not only does this result in zero emissions for most of the trip, it requires just 30 percent of the fuel that a conventionally-powered plane would need and effectively double the operational range of the airliners. What more, the plane wingspan is expected to measure double that of current commercial models, which increases energy efficiency and allows for shorter takeoffs. There a reason why the SUGAR Volt isn ;t coming out until 2030, however, and it has nothing to do with Chevrolet licencing agreements. As usual, it the current state of ba
