Absolutely. This is being pitched as a consumer product you can throw in your bag though, which has definite size and usability constraints. For safety you really don't want people carrying around a backpack stuffed with Lithium Polymer cells either, that's a disaster waiting to happen if someone falls over backwards and pierces one of the cells.

The limit is the batteries mostly. You won't be seeing that sort of performance from an electrically powered helicopter without some drastic improvements in battery power density.

An iPhone 5 battery is about 5 watt hours, ten percent of this is 0.5 watt hour. [0]

The most efficient mining chip I could find information about is the BM1384, which consumes 2.058W at the lowest power bracket. [1]

We would exhaust our 10% allotment in 15 minutes.

In those fifteen minutes our speed would be 8.25 gigahash per second, which would produce 0.000003542 BTC per day [2].

Our total income for 15 minutes of mining would be 0.00000003689583 BTC. [3][4]

At $237.7/BTC our 10% iPhone 5 battery life has been exchanged for $0.000008770 USD.

Assuming 0.17 USD power cost in the United States, the power cost would be 0.000085 USD. [5]

Probably would have been a better idea. Only later in the Anime does he actually need to do things quickly, all the rest really could have waited weeks or even months. That said it wouldn't have made for very interesting watching if he managed to have that much forward thinking all the time.

A mention isn't even necessary. Imagine being Light getting his source of information from the internet, his ISP has a small incident with a lightning storm and they lose connectivity completely for a few days while things get sorted out. Involuntarily information has just been leaked irregardless of all other protections, the deaths of criminals would have been disrupted. In this situation you would ideally be working to some great latency of days or weak to give a buffer of information. It's talked about in the first few episodes that he works ahead in case of sickness, but it's not mentioned after that, possibly because it means he can't use those events as cover for on the spot murders (which would stand out from week old information based murders).

Probably mostly towards the end of getting a good story, two of the behaviors mentioned in this article as erroneous are somewhat intentional (though all the effects aren't). Light specifically mentions that he is making his deaths visible because he wants people to know that there is someone behind it, playing into the idea that he has gained godlike powers and will use them to change the world. He also goes out of his way to bait L to some degree in an attempt to eliminate him, believing L to be the only true obstacle in the way of achieving his end goal. With hindsight this is obviously the wrong move to make (he gave away a lot of information for no good reason), but you can see why someone faced with an invisible enemy might feel like drawing out their opponent is a good idea.

All that said attempting to anonymize his targets probably wouldn't have done him that much good anyway. As a Japanese person his sources of news and information would be at least on some level biased towards hearing about events which have some connection to Japan. Even if he was able to overcome that through the internet, people have a very noticeable habit of treating things physically closer to them as being more real than something on the other side of the world. Adding entropy within a limited information aperture only gets you so fat, I'm pretty sure he would have still had information leaking just through that lone.

The "artificial" ripening with Ethylene isn't really as evil as it sounds, fruit emits it anyway as it becomes ripe. If you have for example some avocados that you want to ripen more quickly, putting them in a paper bag with ripe bananas or lemons will hasten the process significantly. Fruit on its own like bananas will ripen much more slowly than if they are surrounded by a bunch of peers.

Hurricane Electric itself blocks some things though, for example you can't use IRC on standard ports through a HE tunnel.

CloudFlare uses SNI for their lower cost plans.

The ESP8266 has peak draws of almost a watt when transmitting, unless Amazon releases a crank-to-order device that doesn't seem particularly plausible. I'm slightly surprised that they didn't use the Espresso solution here to keep their part count down, but it is possible this model is just to gauge market interest.

Most microcontrollers have extremely low power sleep states, maintaining interrupts on external inputs often only draws the smallest amounts of power. When you're designing for low power electronics like this you often run into the problem of the self discharge of the battery completely dwarfing any consumption your microcontroller has. I'm reasonably confident they chose a lithium AAA simply because they have very low self discharge, and a AAA over something like a coin cell due to the rather enormous amount of power needed to transmit 802.11.

I get the feeling that this device is pretty tentative for Amazon, they haven't gone to huge lengths to keep the price of the build down. In particular there's also a connector on the bottom right of the PCB that looks a lot like it could be for a small screen or some other peripheral.
