So the Wankel is an article all to itself -The materials science problems with apex seals are amazing.

Here is an awesome rotary ‘piston’ engine (DynaKinetic):http://newenergyandfuel.com/http:/newenergyandfuel/com/2014/06/25/how-the-gotek-energy-engine-works/http://gotekenergy.com/

Bosch claims that their internal testing revealed that these new bits provide 4 times longer life in concrete with rebar than standard SDS-Plus bits. How? It all comes down to design.

And I would point out the following things about transmission vs engine: 1. active for longer periods (100ms range) vs. 30ms for 1000rpm engine 2. number of activations is in the range maybe 1/s (worst case city very aggressive driving) vs 16/s engine idle 3. work with much lower and slower pressures (in an engine, you will have 9-10bars at end of compression, before detonating the fuel) 4. transmission solenoid failure will result in disconnection, whereas engine failiure can lead to sudden stall, which the transmission has to disconnect, otherwise wheels will lock-up. Engine damage is implied. From 1. and 3., there are 2 electrical conclusions: they need a lot (10x-100x) of electrical power to do the job. Which leads to thicker wires, massive transistors (with massive heatsinks) and massive EMI. In short…..way too expensive. The concept is nice, but you should already know that things don’t scale in linear fashion and sometimes researching another domain is less expensive than developing this (looking at you, electric cars!). Why use tons of electricity for valves when you can sent it to the wheels?

While the performance is impressive, it does show one of the trade-offs with titanium. It gives you a lower-cost bit than cobalt, but it’s a coating that will eventually wear off and lose its benefits. Cobalt blends with the steel so you get the benefits throughout.

Today Apple revealed a new MacBook Air in New York City, a MacBook Air for the year 2018 and beyond. This new MacBook Air was revealed to roll with a new set of colors, including gold and silver, along with two USB-C ports and a headphone port. This MacBook Air was revealed to have a 13.3-inch display with “4 million pixels” and a 50% narrower bezel around its face.

This aluminum tread plate, two-piece sliding hosebed cover on a KME Predator pumper permits easy access into the hosebed area. Note the latch mechanism at the center of the rear cover.

Panic is contagious, and it can cause otherwise rational, intelligent people to react in ways that put them in grave danger. Human behavior can have a huge influence on fire department operations, especially in a high-rise building fire. I learned that it has to do with the way our brains are “wired.”

Standard Milwaukee Shockwave impact bits are getting an upgrade as well. They’re using a new metal – Custom Alloy76. It pairs with Milwaukee’s Wear Guard Tip to improve on the current generation.
