Comment Re:This is the problem with religious people. (Score 3, Insightful) 903

You can extend the argument. If they pay their employees with money, and the money can be used to purchase contraception, then they risk Hell. Therefore they should not pay their employees with money.

I cannot see the difference between purchasing an insurance plan for employees that covered contraception and paying them with money that can be used to purchased contraception.

Comment Heat pumps (Score 2) 944

Heat pumps have one serious problem. When it gets cold, your house needs more heat and the amount of heat that a heat pump can deliver goes down. Almost every heat pump installation uses resistive auxiallary heat to make up the diffrerence. You are usually better off using a little extra heat from either a small electric space heater or light bulbs in the rooms you occupy to bring them to a comfortable temperature than using the heat pump to heat the entire house to a constant temperuture.

Comment Ironically (Score 1) 180

My car navigation system and "infotainment" system locks out certain seemingly random features while the car is in motion. For example, you can change Bluetooth devices while the car is in motion but you cannot sync a new device to the system. I did not know this. I found it incredibly distracting to try to figure out what the hell was wrong with the system while driving, and I wasn't even the one trying to use the system.

Most likely they are refusing to buy excess solar-generated power at retail rates. They also may charge more for a grid tie-in if the load is very light some days and very heavy other days. This HAS to happen eventually, the utilities cannot buy power at retail rates and maintain their infrastructure.

Comment Re:Which company bought this 'new' rule? (Score 1) 1143

There are so few CEO's that they can't be the main problem. If you confiscate all the wealth of all the billionaires, in total, you get 2 months of government spending.

There is around $50T in total household wealth in the US. The upper 1% controls about 30% of that, call it $15T. Government spends maybe $5T a year total....

Comment Re:Measuring charge by measuring potential (Score 1) 216

The fact that the internal resistance of a battery changes as a function of charge is not the reason that the potential of a battery changes as a function of charge. You didn't say that it did, but you implied it.

There is nothing 'roughly proportional' about the relationship between the potential on a capacitor and the voltage on a capacitor. They are proportional. If they are not proportional then you do not have a capacitor. Real world, non-ideal, capacitors do have some non-linearities, some types more than others, but they are generally quite small.

Comment Re:Bullshit we won't notice (Score 1) 466

I am 6' 7". I don't worry about the person in front of me leaning their seat back because it is physically impossible to do so since my knees are jammed hard against the back of their seat. I do not believe that it would be physically possible from me to fit into a seat on a 31" pitch. I would be more comfortable standing, only I cannot stand up right on most planes.

I would gladly pay more for exit row seating but it is not always available.

 

Comment A netbook is not open. Neither is the pi. (Score -1) 214

I was seriously dissapointed in the raspberry pi. The price is good, but that is about it. It order to get it running, I had to purchase the folowing: HDMI capable monitor ($120, I have plenty of old monitors that take VGA, but none that take DVI/HDMI), usb mouse and usb keyboard ($40, same issue, all my old mice and keyboards are PS2), power supply, case, and memory card. That actual cost of that little $35 board was was well over $200. True, this board will require much of the same hardware, and will cost well over $400 to actually get it up and running. So in reality, it is about twice as expesive as the pi.

Once I got the pi up and going, I realized that much of the marketing hype about being an 'open' development platform for learning about computers was total garbage. You cannot get a schematic of the board, you cannot get the complete spec. sheet for the processor nor can you get much of the source code. It was not the product that I had hoped it was.

Comment Re:Oh yes, store the waste (Score 4, Insightful) 74

There will always be something left. There are a few isotopes of caesium, iodine and a few other elements that have a medium half life (10-100 years), that are biologically active, and have a TINY neutron cross section. The medium half life means they will be around a long time (thousands of years) and will be quite dangerous for that time. Biologically active means that your body will absorb them and concentrate them. The small neutron cross section means that you CANNOT burn them up in a reactor. Long term storage is the only (safe) option for getting rid of materials. Every nuclear fuel cycle produces these, even the much-hyped liquid salt reactors.

Safe long-term storage of waste is not technically difficult. It is politically difficult and distracts from the real danger of nuclear power. The real danger of nuclear power is the almost unfathomable cost of a reactor accident. Not in terms of lives lost, but in terms of property damage. Imagine for a minute the implications of a Fukishima type accident at a US site on a major river. Every city downstream of the accident would have to be evacuated.
