On Venus, no need to stick your head out the window into the atmosphere. The atmosphere will eat through the walls and into you.

If you care about quality, refills are an iffy proposition. If "not quite as black as OEM" or similar flaws are OK, go for it.

Spanking line!

Why have cameras been around for decades but only now these "selfie sticks" are being used?

Extremely large numbers of quality, low-weight cameras is a new phenomenon. A one pound SLR on a 6 foot pole would require a strong wrist and a sturdy pole.

Private streets are frequently maintained by the owning entity. Unlike public streets, your taxes aren't paying to support them. You should be pleased that they aren't a burden on your life.

FUD. I use Linux to play DVDs. It's different from using a dedicated DVD player, because Linux never bluescreens, unlike my dedicated players.

Selfie sticks on an amusement park ride are just crazy dangerous. If you must claim that Disney's consideration is money, include in that money the number of hundred-million dollar lawsuits for death, blindness, dismemberment, punctured organs, etc.. Disney would be negligent if selfie sticks were allowed.

Many photographic "papers" today are actually solid polyester.

That $0.03 / kWh needs to be added to the cost of the electricity used to charge the battery, and factored with the efficiency of the charge/discharge cycle.

Is that 14.42 volts with the battery in the circuit? If so, the battery may be acting as a shunt regulator. (I don't want to seem challenging, I'm genuinely curious.)

Purity may be an issue. If batteries require high purity lithium, additional refining steps might be expensive.

Higher voltage batteries in IC cars have been under consideration for more than 25 years. It's advantageous because of the reduced weight of wiring. There are a few disadvantages. Higher voltages increase the possibility of electrocution. All existing ancillary electrical parts are currently 12 V, so changing to a new voltage means filling inventory in auto shops and dealers with an entirely new stock of electrics incompatible with the old stuff. Apparently, nobody wants to go first.

The demand for perfect information is standard leftist claptrap, designed to entice weak minds into accepting increasing amounts of hatred and opposition to freedom. There is no attempt at honesty there, it's simply "How call I fool you into giving me more power?"

You fail reading comprehension. Manufacturing costs are generally broken down into several categories, such as materials, production, and overhead. Cutting production costs in half will not cut the total cost of the batteries in half.

Amazing. Glossing over facts, ignoring the difference between disproven hypotheses and modern economic theory. Baldly dishonest claims about the effects of petroleum as a fuel.

Our economy was not based on slave labor. The North won the war largely because its non-slave economy was stronger. The South could have had an economy stronger than it was if it had just slowly transformed into a market economy (because free labor is more productive than slave.) (Historically not possible, due to culture and laws of slave states.)

Now our economy is based on generating poison gas from fossil fuels.

That is just plain dishonest. Our economy is enhanced by, not based on, energy production from fossil fuels. The primary byproducts are carbon dioxide and water, neither of which is a poison at the concentrations at which they are currently generated. You are a liar, and you know it.
