Air delivery of supplies to areas where there's no place to land is typically done by parachute or helicopter. A parachute is reusable, but requires a trained rigger, periodic inspection, occasional repairs, controlled storage conditions and, of course, some way to return it to base after the drop. In dire battlefield conditions, used parachute components must at least be made unavailable to the enemy. In jungle areas, parachutes tend to leave the cargo hanging in the trees. Helicopters are expensive to operate, impossible to hide, make for high-risk operations behind enemy lines and can't land in the jungle without a prepared site.
Chase Warren and his teammates at DropMaster Inc. have a better idea: an economical, single-use delivery system that's compact, simple to rig and has the rectangular shipping container with all of the parts inside transforming into the hexagonal drop box! A small drogue chute with a metering line orients the package in free-fall and then deploys the deceleration system — three rotor blades that spin with the cargo (no bearings) at about 450 rpm and create lift to control the descent rate. It penetrates tree cover without a hitch and you can even use the parts as a camp stove to cook those fresh groceries!
Last year at Hannover Fair, lots of people were talking about Industry 4.0. This is a concept that seems to have a different name in every region. I’ve been referring to it as the Industrial Internet of Things (IIoT), not to be confused with the plain old Internet of Things (IoT). Others refer to it as the Connected Industry, the smart factory concept, M2M, data extraction, and so on.
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
