Who cares how much energy is used. I only care about the sustainability of the energy we are using. Currently, reverse osmosis consumes 2-3 kWh/m^3. Americans use 387000 thousand acre-feet of fresh water per year. Which translates to 1.29 acre-feet per capita per year. Everyone always says we are the biggest consumers, so that's why I'm using American water consumption for this math. 1.29 acre feet per year per capita = 0.013 gallons per second per capita, or 200-400 watts of desalination energy per capita with current technology. 6 billion people = 2 terawatts. Sounds like a lot doesn't it? Well, lets see. With Esolar technology we are looking at 8410.3439 square miles of desert. That's about 0.2 percent of the Sahara desert. And e-solar technology uses only iron, aluminium, and a small amount of water that it recycles over and over again. They can't count how much iron and aluminium there is left on the earth, so those resources aren't limited. Please let me know if there are any other resources I failed to account for by listing them below.
Actually they killed the battery, by selling the patent to Texaco oil. This is on large-format NiMH batteries. Although these batteries are heaver than today's lithium-ions they were cheaper on a per-mile basis (You have to rate batteries on a cost per unit of electricity stored in order to understand the true cost). The NiMH batteries in the 90's EV's, like the RAV4 EV, are known to be completely happy with 100,000 miles+. The reason is that they don't care as much about purity as lithium ion tech, and the plates don't change shape in form of nickel-cadmium. In the eyes of me (a layperson), it's quite like an old Edison nickel-iron chemically.
Obesity is not just an American problem, and if it really is a threat can be debated. It's also a British issue, a Canadian issue, etc. We might be the highest right now, but that could change - (we're just a little ahead of you guys:p).
Self-righteousness and health related attempts to control other peoples lives, that's a world wide epidemic with far scarier consequences than obesity.
Efficiency doesn't matter. What matters is the sustainability of the energy you are using. What if you ecodrive a gas prius to work and I drive a cold fusion powered hummer around the world the long way to work. Guess what. The prius used probably 100 times less energy. Who cares though, because the hummer did not emit any CO2. Nuclear to liquids is going to be a lot less energy efficient than straight electric vehicles. But it's gonna be cheaper and have less infrastructure requirements.
Bullshit. That company has not produced a product or even a successful demonstration of the technology. They are claiming they have something 50-60 times better than current technology. Extraordinary claims require extraordinary. And who wants an ultracap when you can have a SMES?
Want an electric car that you can afford? Get a huge van, fill it with 2 tons of lead acid battery. It will be ugly but it will work. Don't hope to recharge it at any decent rate, you'll only find an outlet big enough in a factory. When ever you here nano, think BS. It's going to be too expensive.
The best solution is to make gasoline in nuclear power plants. But we can't build any because we got too much greenpeace. Maybe China can?
I have a 1980's hydrogen car and I'm about to drive it class. It has tank full of liquid carbon hydrides that flow into an internal combustion engine. Want hydrogen? the best way to store it is with liquid carbon hydrides.
RDS is not just an IDE but a class lib. You always want the source code to stuff under you in robotics because of exotic hardware (in 10 years, will there be a driver for a R314-HOKUYO-LASER4 sensor?), exotic set ups (what happens if I have 19 cameras instead of 16?), the extreme real-time nature of the system. Robotics programming is like game programming, computer vision programming, driver programming, and embedded system development all at the same time. Any software that behaves an unknown fashion is bad.
Yep. But it's not just that. Public transport is not a major efficiency gain over cars. It is in some cases an efficiency decrease. My main point is that conservation in the transport sector is not a viable solution, and alternatives will have to be found. Like NTL (nuclear to liquid fuels).
Use boron and aluminium as fuel. They have volumetric (what really matters) energy far in excess of gasoline, and consistent or higher mass energy density. In a fuel cell system, you could easily refuel like a gas car.
But, the energy density for batteries is there with standard issue lithium-ion. A Tesla Roadster can go 244 miles on a charge. Its batteries energy density? 70 watt-hours/kg, or over 150 times lower than gasoline. Can it recharge in minutes? No. But it proves that it works. So why don't you drive one? Because its battery pack costs $20,000. Now, try to put that in a family car and you see that it is cost prohibitive. What we need is a cheap battery with similar energy density (NiCad?), not a 500 mile range battery. Second, it needs to be a plug in hybrid. Basically, stick a little 10 kW gas or diesel generator (or maybe a biofuel genset) in there and you solved the recharge problems. You can't recharge a battery fast right now because the grid just can't pump out enough electricity.
In the long run, I hope that cold fusion will replace gasoline. Boron and aluminium blow away gasoline. If you really want energy density, you have to move up to superconducting energy storage systems (think about 500 gallons of gas in the palm of you hand). But you don't need the energy density. You need to cut costs.
If the laws are uneven in time, that could lead to perpetual motion among other interesting consequences.
For example, pretend that the speed of light is variable over time and remember that E=mc^2. On earth, we build a matter-antimatter annihilation laser and point it at a base in space. When the speed of light speeds up to c=1.1 the normal value, we fire off the laser, converting 10 g of matter into 1.08749377 petajoules. The light energy travels for a time, during which the speed of light slows back down to c. It hits a set up in the space base that converts the light back into matter. We divide by normal c, and are left with 12.1 grams of matter. We mail it back to earth, and send 10 g grams back to the laser (to repeat the process). The other 2.1 g is used as starship fuel, worth over 180 terajoules. Don't rinse, but repeat.
We know Apple is not as vulnerable because they have not had any malware through 2 years of a billion downloads and over 200,000 apps, while Android Market has served malware with significantly fewer apps and downloads.
That we know of. Maybe an app has already swiped everyone's info secretly. We don't know.
FACT:
deism = God set everything in motion, then did nothing and currently does nothing but maybe watch
atheism (me) = No god exists, or existed
theism = God exists and is still a big player in our lives today
agnosticism = Any of the above three could be true, we don't know and we may never know
scientism (me a bit) = The methods of the natural sciences are the only way to gain knowledge about the universe
logical positivism (me) = Knowledge can only be gained about the world through experimental study, or that which can mathematically or logically derived through logical study
materialism (me) = There exists no sprits or souls or other immaterial objects, the universe is governed by a set of laws although we may never know those laws
mechanism (I would like it to be true) = The universe is a fundamentally mechanical system, and the materialist laws are very Newtonian (many QM interpretations are not mechanist, but some are)
deism != atheism != theism != agnosticism
scientism != logical positivism != materialism != mechanism
All mechanists are materialists but not all materialists are mechanists.
OPINION:
Deism is not watered-down theism, it is watered-down atheism. Since God does not interfere with life, to you, he in a sense does not exist. Keep in mind that evolution, QM, GR, the big bang, the germ theory of disease, and many many other scientific theories were not known back in the day, and people filled in "God" to fix the gaps. Today, we know we don't need God, at least past the big bang. I think if our founding fathers knew what we know today, they would be atheists and we would no be having this debate.
Tracking all our cars is one of the long-term goals of the government. The way this will be achieved is by using electric cars and alternative fuels. Because of the lack of taxes on those fuels, legislation will be pushed for a per mile road tax. This will then be enforced via GPS, which will then mission-creep to a full blown tracking system. The solution to this problem is the New Zealand system, which is that non-gas cars get an odometer check and then you pay a fee based on that odometer.
Anyway, cars should not have computers or the Internet in them.

We had this debate a while back. Say, explicitly, what resources are limited.
Take a look at the Rav4 EV. Stick a biodiesel generator in that puppy and you'd have my dream car.

Why would you want to invest in that when you do gasoline decombustion?

If one rat generates 6.5 microwatts, this current computer requires 650 watt psu, that is ~100 million rats
Rats!!!

Culture change time. Rethink atomic power. Rethink public transport.
Zero. Gravity does the rest.

Well, identity theft makes up the difference. And most people writing trojans probably have easy ways to get stolen IDs.
So what. Many of us don't want a break from the screen. We also don't like this healthy lifestyle stuff pushed on us either.
Basically, it is a consequence of "this statement is false"?

Another good example is here. The system actually learned gates for the Aibo dogs that were better than human designed gates.
