This is true. The power flow through a gasoline pump is on the order of 20 megawatts. Try doing that with wires that can be plugged in and disconnected by Joe Average.
I think electrics won't really take off until they standardise on a removable battery. You drive in, stick a trolley under the car, drop the battery and wheel it away. Slide in a new one, pay, and go. Make the changeover quick and cheap and easy enough and it doesn't matter if you have to do it every day. 30 or 40 mile range would be plenty for a commuter, and with a battery that small, performance should be pretty sporty.
Given the free-falling US dollar, you could be right.
That analysis was done last year, so say, $8 a gallon in 2010 dollars, with power @ I think it was 10c per KWHr. Either way, test plants have demonstrated the chemistry involved. There is nothing esoteric in there. It is just a matter of scaling it up, as soon as it is cost effective. Regarding coal, I think converting it to gasoline will be economical long before using CO2 for the carbon is (until you get to "peak coal"). It all comes down to needing cheap energy to do it.
Actually, with sufficient energy you can extract carbon dioxide from the atmosphere, reduce it, combine with H from water, and eventually produce synthetic gasoline. Using the cheapest currently available energy, the cost works out to about $8 per gallon (US). That's actual cost, not including taxes, so no way is it currently competitive with fossil oil. However it does set an upper limit for how high oil prices can go.
In fact, other that the ceiling fans, I haven't replaced a single CFL since I moved into my house 7 years ago.
Ah, I see the difference. You got some of the earlier high quality CFLs, from when they were pushing the changeover. The manufacturers have fixed the pesky problem of low volume future sales. New Improved CFLs now die faster than incandescents.
There are other problems with a short radius centrifruge, including serious blood pressure spikes from sudden movements. Not a show stopper though, the answer is a two part spacecraft with a long cable - think of a spinning bolo. Gives you the opportunity for redundance too.
Check out the panasonic TZ series. They have somewhat resisted the megapixel race, and gone for amazingly good lenses instead.
Latest models have optical zoom from a 24 mm equiv (panoramic aspect ratio) to 300 mm equiv telephoto, and have built in GPS that tags the photo location.
It probably is. TNT has the oxidizer built in, which adds a lot of weight, and also a fair bit of nitrogen, which holds the oxygen, but doesn't contribute much energy-wise.
So you have buttons that say "Use device ID" and "Select a Username". You don't have to actually display the ID. Would also give you some data about how many people care enough to create a username rather than use the UDID. On the server side you need to come up with a way to tie multiple devices to the one account if they use the UDID option. Possibly have a "link another device" option that has the server generate a code transmitted back to the first device, that they have to key in on the second.
Actually, the molecular mass of methane is 16, of which 12 is the C. Whereas the molecular mass of CO2 is 44, (C is still 12.)
So, one tonne of methane burns with four tonnes of oxygen to form 12/16 * 44/12 = 2.75 tonnes of CO2. (and also 2.25 tonnes of water)
Still makes it a sensible energy source though.
The correct way (according to Heinlein:)) is to make a one third vote capable of anulling a law, but a two thirds majority to actually pass a law. Personally, I think all laws should have a sunset date of no more than ten years. If it is a good law, they can pass it again.
There's a fundamental difference between using a service like paypal and having sites directly charge your credit card or bank account.
One is a "push" system, where you decide how much goes, the other is where you give them the ability to "take" and trust them to take what they are supposed to.
I may not like paypal much, but if I paypal $10 to some unknown on-line store for some gadget, that's all I risk. No big deal if it never turns up.
No way will I, or most people, give unknown on-line sites access to my credit card details, or even worse, direct debit authority.
The major advantage of pleading guilty is when it comes to sentencing. Judges and magistrates tend to be more lenient if the accused stands up and says "I did it. I'm sorry. I wish I hadn't and I promise I'll never do it again". It also speeds up the trial considerably, which reduces your legal fees.
Not sure if it still works, but I think you used to be able to move files using the rename command "ren" and giving the full path in the args. You can use wildcards in the args. Try "ren \blah\blah\path\*\*.xml \blah\blah\newpath\*.xml". Note that you cannot change drives with this.
If you're right (and I think you are) then the next industry is going to be biotech.
It still has a lot of techies in the owner/management ranks, especially in the small start-ups that drive innovation.
A lot of it is to do with the pipes into the country. Most overseas content comes in over a fairly limited couple of cables. Looking up the local stuff doesn't cost them anything, but overseas content does, hence the per byte charges. This is also why they don't particularly care about p2p traffic. If it's local, they get the high fees for practically zero expense, if it's overseas you pay the same as any other user, and they get to claim the upload on peering agreements.

Don't forget to stick a diode in the circuit, or the thing will drain your battery overnight. Pretty good chance they skipped that on a cheap panel.

It's not "The Art of War" that they use, it's another old book "The Prince".

Sounds good to me.
Soon it will be.
