The MTR91 and 101 trash receptacles are lined with Blast Wrap materials to mitigate explosion.
Two new trash receptacles promise to contain the blast from explosives planted in the can, capture fragments, and distinguish fire, keeping damage, injuries, and fatalities at a minimum. The MTR 91 and 101 models from BlastGard International were tested effectively to endure blasts of up to 60.47 psi (100 percent fatal) and extinguish a fireball in 3-4 msec, says CEO James Gordon. "Basically everyone outside of 10 ft sustained minor injury," he says. Key to the improvement is the patented BlastWrap™ design, which works by dissipating substantial blast energy through irreversible processes such as drag, turbulence, friction, viscosity, etc. Made from two flexible films of 3-10 mm thickness, arranged one over the other and joined by a plurality of seams filled with attenuating two-phase filler material such as volcanic glass beads, BlastWrap products are lightweight, configurable, and featue a density of 4.95 lbs/ft3 (0.09 gm/cc). With an extinguishing coating of non-toxic fire and flash suppressant elements that can suppress 85 percent of the original blast force, these products also interfere with secondary combustion, reducing heat release and gas pressurization. The trash cans have been tested and approved by the British Department of Defense, which holds some of the world's most stringent procedures for bomb-proof trash can testing. Currently, the receptacles come in only one standard size, but they can be customized and laminated for various colors.

A bold, gold, open-air coupe may not be the ticket to automotive nirvana for every consumer, but Lexus’ LF-C2 concept car certainly turned heads at the recent Los Angeles Auto Show. What’s more, it may provide a glimpse of the luxury automaker’s future.
The complexity of diesel engines means optimizing their performance requires a large amount of experimentation. Computational fluid dynamics (CFD) is a very useful and intuitive tool in this, and cold flow analysis using CFD is an ideal approach to study the flow characteristics without going into the details of chemical reactions occurring during the combustion.
