Comment ...oh, and can anyone recommend an exacto knife? (Score 3, Insightful) 384

Sometimes, for diagnostic purposes I also need to add a second read head to the credit card scanner. It would really be helpful if I could add this to the network, along with the keypad's diagnostic port. Any ideas?

In all seriousness though, there are some real fire protection issues with taking cables from the pump zone elsewhere. Everything in and out needs to be properly sealed to prevent explosive vapors from entering into a non spark-resistant system.

It all comes down to the money. The Republicans can't marginalize their core conservative base because then they lose 80% of their money. What's worse, if they kick the tea party out of their caucus then that 80% of their money goes to fund competitors, leaving the grand old party much less old... but also much less grand.

TFS is about right; if the Republicans focus solely on economic issues in an honest rather than ideological manner then they will shine with GenX as well as Millenials. A lot of the people in those generations have seem to have shifted a bit on the social compass, and that doesn't help the social conservative cause.

That said, I have said I was a social liberal/fiscal conservative since before I could vote, and the only real change in my mind is which aspect is more critical to me. Also haven't voted much over the last 20 years, so not sure if anybody really cares...

This is likely one of three options, the other two being entrepreneurialism and capitalism. An ideal solution mixes all three and provides diverse sources of income. With countries like Malaysia, Indonesia, Thailand, and the Philippines you need to be a little vigilant about the possibility of needing to walk away, especially when you don't have dual citizenship.

Between automation, outsourcing, and government behavior in general, there is no fool-proof solution unless you can buy your own country. You hedge your risks by understanding finance without working in the field, saving money, investing wisely, avoiding debt, and recognizing and taking advantage of opportunities when they arise.

If you aren't willing to do those things, find a business under 50 people that is well run and work for them.

(In IT, the key is actually being responsive (and good). I interviewed four consulting companies, and while they were happy to do an initial (and sometimes follow-up) meeting, all four of them failed to actually provide me with a proposal. #5 is next week... I am even willing to convert our servers to Windows to expand the talent pool; it seems hopeless to find anybody good with Linux in Los Angeles.)

Cash has limited scope. I need to carry about $500 with me for cash incidentals most of the time, despite 75% of my spending being via credit card. I used to be fine with 90% cash and under $200 on my person, but that was a decade ago.

The only thing I can do to manage risk is placing things in corporations.

In terms of the metrics, NYC is penalized for the following: temperature extremes, humidity extremes, tall buildings (plumbing, elevators, etc), and a number of other lesser factors.

NYC is benefitted by the fact that they don't grow anything, or really manufacture much.

NYC should strive to do better. Buildings should be better insulated, HVAC systems should be more efficient, heat recovery should be more widely used, lighting needs to be upgraded with more efficient solutions, and the subway should really try to improve efficiency.

But all these best and worst rankings are bunk without proper context.

It doesn't take this to be off grid; the benefit of the grid is to more transparently accommodate peak loads, and due to the fact that your PV system has to be substantially oversized to generate adequate power on an overcast winter day, relative to cool summer day usage. Being on the grid lets you put that power to use.

Same thing happens with wind.

The long term benefit is stretching the period over which solar power is used; this will reduce the impact of peak pricing. I like the idea; I was actually going to build a 10kWh flooded lead acid system to do the same thing. Effectively you move the cost of peaking directly to the consumer.

The potential down side is you end up with more widespread Critical Peak Pricing schemes, which jack up the cost of electricity on hot summer days to punative rates.

This would be a great solution for a local energy co-op to run low voltage wiring between homes and businesses all trying to be net producers of electricity, but I am not sold on how it works with the current utility grid model.

Assuming you get 2,000 cycles out of the battery, at $350/kWh(B) it is $0.175/kWh shifted. Further assuming 80% round-trip efficiency you are at about $0.22/kWh that needs to be saved to pay for the system. Add in a 5% cost of capital and you need your off-peak energy to be $0.25 less than peak period.

Stated another way, 2,000 cycles is 5.5 years. If you combine a 4kW PV system (roughly $16k) with this, you have an annualized cost of energy of $2,400 (assuming no interest). If you stretch the life to 10 years the cost goes down somewhat, but it is still going to be expensive.

Don't get me wrong; what Tesla is offering is a huge opportunity to make renewable energy viable for the masses, and will likely buy one for my next home. It just requires energy prices to be much higher (or large subsidies) to be economically viable.
