Can the U.S. power grid handle electric cars? If everyone had to drive electric vehicles, could the U.S. power grid handle it? Jason Fenske from Engineering Explained runs through the numbers while he takes a scenic drive, and his answer may surprise you. You almost always learn something new from a Fenske presentation. Now if the power goes out, well, that's a whole different story.

Alzheimer's progress: Light and oxygen treatment clears disease protein in live mice A small, light-activated molecule recently tested in mice by researchers in Japan represents a new approach to eliminating clumps of amyloid protein found in the brains of Alzheimer's disease patients. If perfected in humans, the technique could be used as an alternative approach to immunotherapy and used to treat other diseases caused by similar amyloids.

Tech Tip: Wave spring vs. coil spring -- what's the difference? The key advantage of using a wave spring is in the axial space savings. Whether it is a static or dynamic application, a wave spring can provide the same force and deflection as a coil spring -- but in considerably less space. There are many other advantages of using wave springs, including cost savings when considering the whole assembly. Learn more in this informative Smalley blog.

When should designers use crossed roller bearings? Crossed rollers use a series of cylindrical bearings or rollers set at 90 degrees to one another to form a V that fits into a slot on the rail. Each roller provides an entire line of contact, as opposed to just the point or two of contact provided by liner actuators using ball bearings. The result is less deformation and the ability to carry heavier loads. Read this informative ISOTECH blog.

Pre-Compensated Valve Platform for mobile machines The Pre-Compensated Valve Platform from Bosch Rexroth makes it easier for mobile machine builders to selectively combine a range of hydraulic control valves into a single, integrated, multifunctional control solution -- with minimal need for adapter plates or custom fittings. All the valves in the platform support pre-compensated load-sensing capabilities that ensure the proper hydraulic flow is delivered to each function. The incorporated load-sensing capabilities improve efficiency, can help reduce hydraulic cooling system size and costs, and potentially lower engine horsepower requirements.

Design Tip: Mastering complex features on machined parts CNC machine tools attain greater capabilities year over year, but that doesn't mean just anything goes when it comes to design. Mistakes can lead to expensive reworks and project delays. With this in mind, Protolabs has put together five elements to consider when designing complex parts to make your project a success, including tips on hole placement, deep features, better threads, and how to handle corners. Read this informative Protolabs blog.

Whitest paint ever is also the coolest -- literally Engineers at Purdue University have created the whitest paint ever. Coating buildings with this paint may one day cool them off enough to reduce the need for air conditioning. The researchers say this white may be the closest equivalent of the blackest black, "Vantablack," which absorbs up to 99.9% of visible light.

| Improved low-backlash Slip-Ease clutches | |
SDP/SI offers a new, low-backlash variant of its existing line of multi-plate in-line slip clutches. Both versions feature an all-mechanical design, which makes them considerably cheaper than electromechanical alternatives. These clutches are commonly used for overload protection to prevent injury and machine failure, but have a wide variety of other applications such as tension control and positioning retention hinges like the ones in reclining chairs. The slip plates are layered with friction pads in between, and an adjusting nut sets the slip torque by squeezing the plates together. The outer plates are tabbed to fit into the output housing and the inner plates are connected to the input hub, so the two ends disengage from one another upon slipping.
