    How many births outside of China is coal responsible for to make those numbers?

    Not sure about the question? What do you mean births? Unless you think the 170k for the global average is a total - it's now, it's the average number of deaths per TkWh. IE if you generate 1T kWh via coal power, on average 170k people are going to die from it. China's record, at least when the statistics were gathered, was so bad it more than doubled the death rate for the global average, so they broke it out as a specific example. I understand that they've improved somewhat since then, but consider the pollution in their cities...

    I guess the initial costs might be quite a big higher than just getting a pump and a semi-permeable membrane.

    It takes an average of 3kwh to desalinate 1 m^3 of water via reverse osmosis. Per this report it's 4-12 kwh of thermal energy to distill 1 m^3, plus 1.5-3.5 kwh of electricity.

    If we figure on 10 kwh of thermal and we're setting stuff up so that we're down near 1.5 kwh of electric*, then consult a solar map, we're looking at needing 2-3 m^2 of collector per m^3 of production a day(at 90% or so efficiency), and it only cuts electric costs in half.

    WHAT PROBLEMS? I've told you multiple times - they aren't PROBLEMS they're CONCERNS. A Concern is an issue you have to address or it MAY become a problem.

    Example: Solar panel installs shooting towards 100% of DML is a concern to HECO until they studied the issue more and determine that 120% is still a safe level. Going above 120% is still a concern because they have to examine and upgrade their substations.

    There are a number of competing systems. I don't know. I guess the point is that if we set a low target like 1:1000 (99.9%) its amost surely a net positive.

    If you're using it as a design consideration, that's fine. I was thinking about real-world systems. Another thought I just had is the question of how fast the authorization takes place. If I grab the gun out of my holster, will it be ready to fire by the time I have it raised/aimed?

    But the anti-smart-gun crowd tends to frame their objection around how its automatically going lead to more innocent deaths.

    My main fear on this is the reliability issue. As far as I'm concerned, my carry weapon* needs to be able to work through gloves, primary and off hand, at -50 and over 140F. It needs to be able to last, with routine maintenance, over 20 years(military), 40 for private. It also needs to be easy enough that I don't end up not using it, and cheap enough that I feel it's worth it.

    50 million year divided over how many police officers? Google is suggesting that its around 780,000. That's $64 per year per officer to save at least 5-10 lives year.*

    It's too expensive for me. I value the 'average' human life at $2-3M at this point. Of course, I'll also state that if any officer or department wishes to switch that I'll support them. It might run a touch more than $1k though - the mechanism will probably have to be beefed up in order to survive the shock of a .40S&W round as opposed to a .22lr. It might also increase maintenance costs.

    Vests are normally around $2k and have about a five year lifespan in use, but an officer is a lot more likely to be shot than shot&killed with their own weapon.

    * That only considers officer deaths. How many civilians are shot with stolen police weapons? How many of those would be eliminated with a smart system? In some cases the thief would and could defeat the system... but surely in some cases not.

    First, I assume that any stolen smart weapon will either have the system disabled or reprogrammed.
    Second, I think the numbers shot with police weapons are very low - they aren't going to increase the numbers by much. Not many weapons are stolen, and not many of those are subsequently used in a murder.

    I'd also like to wind out by saying one concern i have about this particular smart gun tech highlighted in the TFA is that it appears to be a wireless link between wristband and weapon -- and I'm concerned about the ability for it to be jammed.

    Unlikely short of highly organized crime, but I understand the point. On the other hand, how do you propose having the gun authenticate if the officer is wearing gloves?

    I should probably state my views a bit better: I believe that until the technology is good enough that the police are voluntarily embracing it that it's not ready to be mandated to civilians. If a civilian wants to buy an unreliable weapon, that is his choice. But it should not be forced on him.

    As is, the police will lobby incredibly in order to exempt themselves from any such requirements, which tells me it's not ready yet.

One downside is that it didn't mention officers killed by another officer's weapon. Balancing that would be that there are multiple cases of cops shooting each other.

Round up to 1M guns**, you're looking at $1B to transition them all to 'smart guns' if you do it as firearms wear out. If you accellerate the replacement you're looking at $2B.
