 | Flexible thermoelectric generator wraps around hot pipes
A new flexible thermoelectric device developed by researchers at Penn State can wrap around pipes and other hot surfaces and convert wasted heat into electricity. In tests conducted on a gas flue, their device exhibited the highest reported output power and device power density from a single thermoelectric generator.

 | Speedy delivery: 2,000-hp Ford SuperVan does 0 to 60 in under 2 sec
In a bid to show off the over-the-top capabilities of all-electric truck power, Ford has created a 2,000-hp one-of-a-kind SuperVan that is sure to be the envy of many delivery drivers worldwide. The new vehicle is the fourth of Ford's bulked-up SuperVan demonstrators that stretch back to 1971, but this is the first all-electric one and certainly the first to feature a dedicated burnout mode.

 | Engineer's Toolbox: How to pin a shaft and hub assembly properly
One of the primary benefits of using a coiled spring pin to affix a hub or gear to a shaft is the coiled pin's ability to prevent hole damage. Another is the coiled pin absorbs wider hole tolerances than any other press-fit pin. This translates to lower total manufacturing costs of the assembly. However, there are a few design guidelines that must be adhered to in order to achieve the maximum strength of the pinned system and prevent damage to the assembly.

 | Recommended: Alternative to traditional drive systems
Nexen Group has introduced a stainless steel version of its patented precision roller pinion system (RPS), which engages two teeth simultaneously to achieve superior accuracy with zero backlash at any length. RPS is extremely quiet and 99% efficient, with a long life up to 36 million meters. It provides a low-maintenance, durable alternative to rack and pinion, ball screw, and belt drive technology. The RPS is used for a wide range of applications including laser cutting, plasma cutting, and gantry applications.

 | Machine learning eliminates cogging for linear motors
The highly dynamic AL8000 linear motors from Beckhoff now meet even greater requirements for accuracy and synchronization with the new TwinCAT Cogging Compensation software, which compensates for cogging forces. Cogging forces in linear motors are caused by the magnetic attraction between the iron core in the primary part and the permanent magnets in the secondary part. AL8000 linear motors are particularly suitable for high-precision applications such as milling machines or laser cutting machines.

 | Solar Power: More light captured without sun tracking -- even on a cloudy day
In a real "why-didn't-I-think-of-that?" moment, Stanford University researchers designed a deceptively simple, pyramid-shaped lens device that can efficiently gather light from all angles and concentrate it at a fixed output position. The graded index optics have light-management applications in solar power arrays, solid-state lighting, laser couplers, and more. Testing demonstrated impressive results.
