Hm, never heared that the mosquitos themsleves are infected. The parasites live in the human blood the mosquitos suck. Not in the blood of the mosquitos. But perhaps they can infect the organs of the mosquito. I found an article on sciense mag, http://www.sciencemag.org/news...
Well, imho if it really gets used up in the sense that it reacts with other chemicals participating in the reaction, then it is nto a catalyst.
Catalysts can also erode - for example, in the Ostwald process for making nitric acid, there's almost always a catalyst recovery stage downstream, because platinum and rhodium are very expensive, and erosion rates are high. Even the process of erosion varies - for example, in some cases it might be substrate attack, or active surface attack, or formation of dendrites which break off, or all sorts of things. Of course, that is why I gave the concret example, even if it does not fit to those you mention here:D
It actually does make sense. iPhones only have one SIM card. I travel a lot and need extra mobiles and extra SIM cards all the time. Also data exchange of Apple devices simply sucks, either you need a cloud or iTunes, how ever there is a third party tool, iExplorer, that is wonderful. So: for the extension of the iPhone you need obviously an OS, and Android is the first coming to mind. The idea might look strange on the first glance, but I'm sure there is a market. Especially if there was an iPhone 4/5 version, too.
It is catalyst, I suggest to read on wikipedia what the word means. So: no they don't get used up. However you could imagine situations, e.g in cement or concrete where you add a 'catalyst' for whatever reason, and when it has hardened out, you obviously can not remove the catalyst anymore.
I know how the power market/grids work. I was just not aware that there are countries where metering is "out sourced" to yet another participant on the market. I believe in Germany metering is always done "on the last mile", that would be the grid operator. On the other hand it does not exclude the idea that the metering data is used else where for calculations. Or that he in theory could hire a "meter reading" company that does the footwork, just ener heared about such a thing. On the other hand, for heating, there are a few specialzied companies that only provide meter reading.
If they've had working prototypes for that long then why isn't in operation anywhere? Germany does not need them, we sold basically the "TransRapid" to the Chinese (a mag lev train outside of a vacuum tube). In Switzerland the plan was, and still is, to bore tunnels under the mountains. So far no one really decided to build something like this. But I would not be surprised when the basic industris for cabines and other parts are developed that Switzerland will again look into such plans.
We talk about a vacuum tube, where an air thight cabine under pressure of 1 atmosphere is traveling... on mag level rail. There is nothing it can crash into. To have something to crash into, it either needs to hop from its rail, or someone needs to quickly open the tube, place an obstacle, clsoe the tube again and pump out the air again... good luck with that.
A catastrophe inside of a vacuum tube on a rail can only happen if the rail breaks, so: there are no forces compareable with an air plane crash.
But of course you need a meter that can measure power consumption at 15 minute intervals or so, and that's not something the old-style analogue meters can do. Of course they can do that and do actually do that. They are just not connected to the internet and are not able to switch on or off appliances.
The only reason for the introduction of "smart meters" has been to collect personal data to sell and to con people into more expenses... You seem to forget that Netherlands is in Europe, not in the USA. I took the liberty to highlight your errors...
There is no discernible reason to invest scarce resources in "smart meters" (which are looking more like "dumb meters"). Ordinary old-style meters do an adequate job, and give employment to a lot of meter-readers. (That's a good thing, by the way). They are sufficiently accurate. Smart meters are used to transform the old style energy grids into "smart grids", you might want to google what that means.
There is no "meter exchange conspiracy" and if the meter is a "smart meter" or an ordinary meter has nothing to do with the fact/question if it is read by a human or online... facepalm.
The only logical motive for installing "smart meters" is for the manufacturers to make loads of money That is a pretty idiotic standpoint.
All they've got is meter readings. That's all. They don't know (and in most markets, they can't control even if they want to) what kind of meter is fitted to each house. There's a separate metering company that does that. To ensure fair play, there's a certification and testing requirement - but if that test is flawed (which is what the Dutch study suggests), then there's no real fallback. a) I doubt there is an "extra metering" company b) there is feed back, as the sum of all meterings must match the feed in of power (that is how the "utility"company either buys power from another power company or runs their own plants accordingly). Obviously with such a huge discrepance they know since ages that they have faulty meters. The meters are not used to "stear" the plant. That is simply done by keeping the frequency in synch, however the power company knows exactly how much power it fed into which grid and how much power it bought.
(because those same meter reads are also used to determine how much power your supplier needs to buy) The meters are not used for that. That would only half assesed work if all meters where correct and every household had one. Buying and feed in is controlled via the grid frequency, see above. However you can use the data to forcast how much power you want to buy tomorrow...
Air pressure is not vacuum. A vacuum is a lack of air pressure. Ofc as long as you have air you can construct as high pressures as you want, with explosions, e.g. In the case of that tube you can only have exactly one atmosphere pressure difference, not 1000nds as in explosions.
Your ruler experiment makes no sense at all.
The results could be catastrophic to say the least. You must be an idiot.
Hyperloop tube gets a hole. Air streams in. Air slows down the cabin, probably to a halt.
What exactly do you think is dangerous in that scenario? Hu?

Those iPhones are not iPhones. They only look like them, including the icons of the software. They run Android.

Mosquitos are immune to Malaria ... but they suck blood from humans ... and hence transport Malaria parasites from one human to the other.

Germany does not have state funded/financed press or other media.

Depends on the amount of air to pump ;D I guess you can google that. Or get fancy and try WolframAlpha ...
If they've had working prototypes for that long then why isn't in operation anywhere?

What has teh tpoc to do with laws of energy conservation?
For prototypes you can google your self, rofl. I would start with ETH Zurich and/or Ruhr-UniversitÃt Bochum ...
Sigh ...
Interesting, but sounds a bit strange.
In germany the metering is done by grid operator. And balancing power is either provided or bought by the grid operator, too.
Yeah, and 90% of the cell phone users have no cheap plan to call friends in foreign countries, e.g. from Germany to Thailand, or Australia ...
So go back under your rock ;D

That is a pretty idiotic standpoint.
I had no idea how those numbers translated into kWh, or the spin rate to Watts. ... what else do you think? Easter eggs?
Hu? The old meters counted kWh
There are plug in devices, think about an extension cord, which have a meter build in. Unplug TV, plug "meter" in, plug TV into meter ... done.

Those of us who do have a background in hardware and physics look at this stuff ...
You certainly have no such background.
As I mentioned before: you are an idiot.
Germany and more importantly Switzerland has working prototypes since over 30 years.
The question, exactly as with the "Transrapid" is: who builds it first, who has the money, where is a good spot.
How arrogant and ignorant can one be who is flooding this /. article with bullshit posts that lack any economical or scientific background ... wow.
A maglev in a vacuum tube is engineering wise the most simplest thing one can imagine ... and you are full of hate against it. Get a life man ...
No, the point is that airplane accidents involve forces that normally preclude survival. JUst like with a hyperloop track.
The hyperloop has no such forces. You are an idiot.
Air pressure is not vacuum.
A vacuum is a lack of air pressure. Ofc as long as you have air you can construct as high pressures as you want, with explosions, e.g.

Hyperloop tube gets a hole. Air streams in. Air slows down the cabin, probably to a halt.
What exactly do you think is dangerous in that scenario? Hu?
There is no massive amount of pressure.
It is exactly one "atmosphere" of pressure.
There is no recovery from accidents
Yes there is. Because there is no serious accident thinkable, facepalm.
if Hyperloop was to get off the ground
Of the ground? It is not flying, so I guess you meant it metaphorical?
, and to be honest I don't believe this project will work. ... we only lacked a guy/company to build it.
We have "prototypes" since 30 or 40 years
