When electric cars are cheap enough for the average me to afford, I'm going to put big ass engine/transmission sound effects in it and see how long it takes for people to notice I seem to have 20 gears.
It gets 109 miles in Europe, and 73 in the US due to different driving patterns. Electric cars actually do better in stop and go city traffic than on the highway because they can take advantage of regenerative breaking. Heating however, absolutely tanks your mileage. Maybe knock off 20 with the heat cranked up.
The hack is a more accurate charge gauge. The computer can measure the SOC of the battery to within less than 1%, but dumbs it down to a strip of 12 bars. When get to the last bar, all you know is that it's less than 1/12 SOC. You could have anywhere up to 8% left. This tells you exactly how much.
The reason for this Is that it is quite difficult to measure the state of charge of a battery electronically. All you can know for certain is that (for Li-ion) 4.2V (when charging) is 100% and 3.0V is 0%. What smart batteries do is measure the amount of energy you've taken out of the battery and subtract it from the capacity of the battery. The problem with this is that the capacity changes over its lifetime. What a calibration charge does is completely discharge the battery from 100% to 0%. The microcontroller (yes, your battery actually has its own computer in it) makes a note of how much energy the battery supplied during this period and uses it as the new total capacity.
It would be very large, kilometres. You only colonize a place for it's resources. The only thing I can imagine that we would absolutely need is surface area. We've run out of land to live on. The asteroids are the physical resources. Getting from an NEO back to earth orbit can be as low as 100m/s. Getting from an asteroid to the moon would take at least 2.5km/s. Microgravity mean you can move anything wherever you want it. Construction on an incredible scale just takes longer. A sufficient radiation shield is 2 meters of crap left over from asteroid mining. The hull is one meter of steel, add armour technology to taste. Of course mirrors are adjustable. It's either oriented to reflect sunlight on to the the habitat, or slightly rotated so that it isn't. Insulation? You just balance the heat absorbed from the sun with the heat radiated into space.
As for the sky..... I have no excuse. I don't know what I was smoking.
Ok, yeah. When I was saying capital gains I was just thinking about the stock market. The only time a company makes money on a stock is when it is first issued. After that, if you buy a stock, the only difference is the stockholder you bought from has your money and you're the person that the company now pays dividends to for as long as it exists.
Gravity is cheap. float a tin can in space and give it a spin. In summer at the equator, 20 degrees centigrade as about the highest possible temperature on mars. it averages 0 degrees in the middle of the day. At night, it can hit -70. Add a few mirrors and radiators to your tin can and you can have whatever temperature you want. The deepest points on mars almost reach 9 millibar. It averages 6. The atmosphere in your space can is perfect. You should know. You put it there. Your space can is in earth orbit for convenience, so the sun is more than twice as bright there. Near earth asteroids have tiny delta vs and have lots of carbon, ice, metals and silicates. As a bonus for propellant, it's already in space. On mars? You have the freezing, empty desert. The sky is black except for the clouds of ice and solid carbon dioxide. In your space can with a pair of binoculars you can wave to the people that live on the ceiling.
Colonizing Mars in the foreseeable future is indeed batshit insane. Seriously, there's no point. Even when we start running out of surface area, space habitats will make more sense.
Capital gains are not proportional to the amount effort you put in, they're proportional to the amount of money you put in. They're also exponential. If you reinvest, you're going to make more next year than you did this year. You're don't just make money, you make more money the more money you make.
Your father may have spent a lot of effort, but was it work? What was accomplished? When someone goes to work at the widget factory, something has changed. Several people who did not previously have widgets now do. The stock market? From a distance to me it looks like a continuous racetrack with a lot more horses.
I'm not advocating singling out the 1% richest people in the world and taking all their money, but any system where the only possible result is that the rich get richer needs a serious reexamination.
Titan is already known to have lakes of methane, which in the far off future will probably be an important resource in the form of propellant. If mars did have oil, you'd need to construct launch vehicles on mars, or you would burn more fuel getting there than you would bring back. I would hope that by the time we get to that point, we will have moved long past oil.
No on all three counts. Space habitats have much less surface area to cover with biosphere, their escape velocity is zero, and are literally designed with all the creature comforts. The only catch is you live in them, not on them.
To put things in to perspective, if a person has one billion dollars they can give away one dollar every 4 seconds for 100 years and still have over $2 million per year left over. Alternately, if a person made $1000 an hour, he would have to work for 114 years to have a billion dollars. Assuming a 40 hour work week, he'd have to live for over 500 years. $1 billion is minimum wage for life for 1000 people. How does any one person get this rich?
To prove there are questions to which there is no answer, I invoke Russel's teapot. There is an invisible, intangible teapot orbiting the sun between the earth and mars. You can't see it, you can't touch it, you can't sense it in any way. In fact, it has no effect on the universe whatsoever. Does is exist? It is impossible to prove, or even produce evidence that it does or does not exist. Further enquiry into the matter is completely meaningless, ie. unimportant.
When someone says it could not have been an initial creator called god, what they actually mean is that it is equally likely that it was an initial creator called the Flying Spaghetti Monster. Do you agree that that is a valid explanation?

"Foot" in their name refers to the fact that the ball was historically 12 inches long from tip to tip.
+1 Informative. I always thought it was silly to call it football when you kick it once and then spend the rest of the time carrying it.

It didn't happen just by accident, it happened by an uncountable number of accidents all starting where the last one left off.
The whole point is that there is equal evidence for each. None at all.

We'll have run out of fossil fuels long before we're building space elevators on mars.

It does. It's cylindrical and spins.
I'll wait to see what Netcraft has to say about this.

$100 million is about what the US spends on Afghanistan in 36 hours. It would last 6 in Iraq.

Ok, two days late, but seriously? You're asking why less of something is is less than more of something?
Socialism and communism are based on hate, greed and fear? How'd you come up with that one?
Ok, Plug your radio into a laptop with a satellite tuner and download the latest key.
Root users have root. More at 11.
The random group of soldiers already has encrypted radios to do the asking. How much harder could it be?
