While working on a project for a television program,
several-times-over Gadget Freak John Tindall started tinkering with a pulsejet
engine. Pulsejet engines were used by the Germans during WWII. The technology was
left behind by turbofan jets. But Tindall found the pulsejet well-suited to garage
- and Gadget Freak - tinkering. Apparently there is a wide community of
hobbyists playing with pulsejets at home. Tindall came up with a cyclonic-valve
radial design that makes for smoother airflow. He proved the concept with
plastic and aluminum valves - but the gadget backfired and blew up. Next step, a
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
