Still, early in 2018, Crystal IS announced the Klaran WD (Water Disinfection) LEDs that it said crossed the $0.25/mW threshold of cost-to-power-output ratio that some have projected as the point where commercial water purification products would move to LED technology. Crystal is unique in the UV field in that it relies on a homogeneous approach to manufacturing — growing AlN (aluminum nitride) epitaxial layers on an AlN substrate. The Klaran WD products can deliver up to 40 mW of radiometric power output. Crystal also authored a contributed article earlier this year that discussed usage scenarios for sterilization products that make today’s UV LEDs far closer to volume deployment than some have thought. The instant on-off capabilities of LED technology mean that SSL UV implementations do not have to run continuously in the manner of disinfection systems that use legacy lamps.

The Midwestern couple has joined the upper pantheon of Republican donors alongside names like Koch, Mercer and Adelson. They have spent roughly $26 million on the current election cycle, supporting more than 60 congressional candidates, working outside the party establishment to advance a combative, hard-right conservatism, from Washington to the smallest town.

The new LED headlight and all the mounting brackets add almost 700 grams to the bike’s weight, but it’s worth it

This is an article that has been bouncing around in the back of my brain for almost a year now. When I first got my Sur-Ron Light Bee (Firefly) Electric Motocross bike I expected that I was going to use it for single-track riding on trails and in the snow. After trying it out in the snow and on the trails I decided that I preferred my quiver of electric fat bikes for a number of different reasons that I’ll explain later in the article. What I didn’t expect was that I was going to use the Sur-Ron several times a week to create my new tree farm on my 45 acres of mostly open field in Upstate NY. The last year I have gotten pretty much obsessed with Chestnut and Hazelnut trees and have planted over 500 trees on my property this year alone (and another 500 at my wife’s house) with the help of this electric motocross bike. It certainly was not the application I expected to use it for, but for rapidly getting around 45 acres of land without any roads on it, the Sur-Ron is hard to beat. Over the next several years I expect to plant thousands of nut trees every year until I either get sick of planting trees or I just run out of room.

Kevin: Here is the problem with the comparison to other countries with the same 0.05. Those countries do not rely on having their own car. Public transportation is far superior in those countries. Not to mention many just ride bicycles that are available for free to use. We are a society that is hyper dependent on having our cars. You have to change more than just the alcohol limit. Otherwise you pretty much kill the business of bars and bar/restaurants. This is going to be a huge revenue generator for Utah and a lot of peoples live will be scarred. Having 1 or 2 drinks is going to get you arrested. The is legal return to prohibition.

Reading the patents, it’s actually rather exciting to see common tricks both reinvented and improved over the years. Starting in the mid 60s, we start to see basic extrusion elements that interlock at the corners. Their cross-sections are rather complicated, but the fundamental concept of interlocking elements is present. In the late 60s, we start to see slotted inserts and derivatives. In the 80s, we see mature ‘T-slots,’ albeit in an unfamiliar profile. In the 90s, we have something that’s far more mature: a simple, repeatable slot pattern reproduced on various geometric shapes.

More recently, Samsung has announced what it calls FEC (fillet-enhanced CSP) LEDs. The architecture utilizes a reflective coating on the four sides of the structure to eliminate side emissions and ensure that all light is extracted from the top surface. Five-side emission is perfectly acceptable in applications such as troffers with wide beam distribution. But the FEC architecture is intended to support directional SSL applications such as spotlights. At launch, Samsung announced the FEC products in what it called a mid-power 1W component and in a high-power 5W component. The designs deliver efficacy in the 200-lm/W range at cool CCTs.

Heatherwick and I stopped on the Vessel’s seventh level, by temporary signs that warned “Caution: Tripping Hazard.” Heatherwick said, “Walking up sixteen stories is a daunting thing, but I think you’ll be distracted by your experience, and not notice your legs.” A part of the Vessel’s appeal may be the work of avoiding other visitors: it may set a challenge similar to that of exiting a subway station efficiently, but lasting an hour.

Three months later, music fans were rocked yet again when Swedish DJ Avicii was found dead in a hotel room in the Middle East on April 20, just days after he’d tweeted in celebration of his 2018 Billboard Music Award nomination, at the tender age of 28. "It is with profound sorrow that we announce the loss of Tim Bergling, also known as Avicii," the musician’s rep statement, obtained by E! News, read. "He was found dead in Muscat, Oman this Friday afternoon local time, April 20th. The family is devastated and we ask everyone to please respect their need for privacy in this difficult time. No further statements will be given."

Unlike other HH LIBS units that measure beryllium, the SciAps Z is capable of measuring trace amounts of Be down to 10 ppm, thanks to the power of the laser and the argon purge capability.

“RIff off” means to take inspiration from someone else’s work and then make your own thing based on it. “Rip off” means to take someone else’s work wholesale or pass it off as your own. There’s an argument to be made which of these more closely descrbies the various forms of T-slot extrusion.
