Boeing, despite having moved their head office, still makes planes in WA state where their head office used to be, because all the expertise and equipment is there.
No, it mimics the sun well, but CRI (color rendering index) is more telling.
High efficiency lights aren't perfect, but it is silly not to always optimize efficiency.
Even when you need heat, there are more efficient ways to do it than run current through a resistor.
That said, there are a lot of shitty bulbs on the market, and it is a shame. Try to find bulbs you can look at without seeing the helix on fluorescent bulbs. LEDs are hard in most places, but it is getting better.
School shootings are much more of a suburban thing than an inner city thing. They are generally carried out by people who feel bullied. While the history of school shootings in the US dates back to its founding, there are also quite a few shootings elsewhere. Media attention has dramatically increased of course, but it isn't like they happen every day.
The answer to the problem is really anti-bullying training of students, and it happens now. There will always be something, but teachers carrying guns is likely about as effective as putting everybody in a bubble.
Depends on the type of vpn. Plenty of systems that allow very granular access to specific applications or resources.
I'm pretty sure deployment time (including programming) for Kiva is much more than 24 hours.
While I am all for automation, Kiva is about as dehumanizing a system as I could imagine possible. It will be interesting when things like ABB's FRIDA dual-armed table-top robots become reality.
Actually, Walmart has solar panels on a number of their facilities, and has for 20 years. They do it for both green-washing and because it has a positive return on investment.
Distributed generation is an important concept for both efficiency and reliability.
The simplest way to push for rooftop solar is to change the structural design codes so they must add 5psf dead load for solar panels in every building.
You are missing the point. Verizon is FTTP where P is premises. In all cases, there is a dedicated ONT per customer. A building with three apartments will have three ONTs sitting outside with three battery backup units inside. Your neighbor gets a different ONT. Each ONT has its own fiber connection; nothing is daisy-chained.
You are referring to FTTN, where the N is node, and refers to a cabinet that serves 20-2000 customers typically. In the US, these cabinets have had fiber for a decade at least. If the Node is more than 100m from a premise the service provider's choices are to run local fiber, DSL, or coax. Almost nobody runs dedicated coax from a node to a customer; the only reason you use coax is to take advantage of the bus topology. Very few providers would chose to run fiber just from the node to the premises, as they would need an extra media converter; about the only reason to do it would be to exceed the speeds you can get from xDSL.
You can do Ethernet to the ONT if you want to, which can eliminate the Verizon router inside altogether (if you don't use them for TV). To upgrade to gigabit you need a new ONT usually, but the system can easily accommodate gigabit throughout.
AT&T's service is a mess in comparison. I've had several friends who needed the 30-year old copper replaced at least from the street to the demark point.
Today using FTTN as anything but a stopgap to FTTH is really a joke.
For Australia, the original goal and benefit of the NBN was that the physical infrastructure is independent of the service provider. FTTN makes that difficult.
Under carpet power and data cables exist, less than 1/16" thick IIRC. Not a great idea for a whole office though.
Raised floor is nice, or can be. Best to use it for HVAC as well though as individual users gain inexpensive control.
Must be a bastardized translation or something; Volvo's headquarters (prior to purchase by the Chinese anyway) was Gothenburg.
Tape works very well for applications where you have a large number of archival batches; us use the fixed resources (parent's "c") more per TB storage. Once you have a tape silo with 100,000+ slots, your incremental storage costs are very small.
It will always be easier for a computer to evaluate likely passwords that a human would create than for the human to come up with an algorithm that the computer would not anticipate. Password generators eliminate this break point, but create a new weak point in that the password must be stored somewhere other than memory.
My wife might do a great job of creating passwords, but if they are stored in an unencrypted and unobscured place then they aren't necessarily more secure.
No. The utility company wants it in place in order to sell more electricity and make more money. Making electric cars viable is more valuable than the profit off a single station.
Actually getting one installed at a Target is fairly likely if requested. Might not be in the employee parking area, but I imagine you could use it for an hour without anybody complaining. Ok, so my local target has a few more Teslas running around than most, but still possible on a broader scale.
You can have third party providers install the stations and sell back the charging. In Claifornia the utility companies have a pretty streamlined process for it, complete with incentives.
