I'm with the original poster.... unlimited energy makes fresh water an almost trivial task. It is technically feasible to pump fresh water hundreds even thousands of miles. The city of San Francisco has most of its water from just wast of Yosemite (Hetch Hetchy) and it is almost all gravity feed, only one set of pumps in >100 miles.
Distillation or Reverse Osmosis requires energy, but the technology has been available for many decades and is quite good.
The plan is fair, only if they drop the "unlimited internet" from their advertising. In my book, 25 Gb != "unlimited" Hopefully users will vote with their feet, assuming they are in a market that offers a choice.
But all that "wasted" power is turned into...... Heat Imagine all the BTU's that are not needed from your central heating unit due to this "free" heat from all your electronic appliances. Imagine all the $'s you are saving.... oh, wait.... is it summer time ? Well scratch the previous paragraph
It kills me to explain, yet again, that memory is chips and is NOT the same thing as disk space. People see memory (resource) errors on their windows machines, then delete a couple of files but can't figure out why they still have the same error.
Yes, modern appliances are far more efficient than even 10 years ago. The parent takes care of the case where the generator is not large enough to run both the fridge and freezer simultaneously. (Or doing both while also running a base load of lights and maybe a furnace fan).
In some states, if you are caught streaking and it "is possible" that a child saw you, it is grounds to be labeled a sex offender. Makes me wonder how far will we go to stop undesirable behavior?
If you are only considering user interface, the answer is easy:
HP/Agilent is the worst
Tek is the best
LeCroy falls somewhere in between By all means, take the test drive, but in 2 weeks you will agree with me.
While the user interface IS important, there are other features that are important to your users. What is the width (# of bits) and how fast is the ADC(s) ? How deep is the memory? Can you save waveforms on floppy/thumb drive/ network ? Can you zoom ? Will the scope trigger reliably? And a host of others. And, as with most things, each fancy feature comes at a cost. There might be some benefit in weighing the needs of your users with your budget (and also consider that all three manufacturers have a university discount program)
So, wisely consider all of the above, then go buy the Tektronix:-)
And the software is smart enough to decide if you are driving the car or are a passenger ?? What about if you are on a bus or train ?? Seems like someone being paranoid is going to drastically limit the usefulness of a cell phone in the near future. How does one keep this from happening ?
Has anyone else noticed that, for identical items, those sellers allowing checks/Money-Orders will generally have a higher final bid than those requiring a paypal account ??? It seems that the market is adjusting to the perceived risk of checks and the prices are higher. I wonder if Ebay management realizes this will reduce profits.
Unfortunately, pretending to be someone else may save you some tolls, but eventually someone will figure out who is posing as a different driver. The Bay Area bridge, airport parking lots, and many other places have cameras that photograph both the driver and the license plate of the vehicles that pass. Maybe some good will come out of all this surveillance.....but probably not.
This reminds me of a news report when the shuttle tried re-entry with damaged tiles. The report stated that the temperature on the left wing was 15 Degrees (C) hotter than expected. And for all of us metric challenged Americans, the reporter incorrectly translated that to be 59 Degrees (F) hotter than the normal temperature in that part of the wing. It took me a minute to realize the translated number was 32 degrees off. I never heard a correction on that, but I guess they were pretty distracted by that time.
I think you mean LOW Voltage DC, the high currents force you to use very large wire to get appreciable power to the load. Actually, DC line losses are less than AC for a given voltage and power transfer.
Car removes hydrogen from water: Easily done with electrolysis. The technology for this has been known for over a century.
Car extracts electrons from the hydrogen (... as it recombines with O2 to form water) Otherwise known as a hydrogen fuel cell. Again the technology has been in use for many years and if you ignore some "small" problems with membranes, this also works.
Car runs on electric motors powered from the hydrogen conversion - Electric motors for powering a car, this one is easy
So to summarize, customer buys this car. Then uses water to power it !!! As long as "customer" can plug the car into someone elses electrical socket to run the hydrogen converter, his only consumable is water.
I wonder if his neighbors would get suspicious about the large orange extension coming across the yard between the two houses ??
While touted at free energy, it actually comes from all the people. I doubt all this foot traffic will generate significant energy without people noticing/complaining. Walking 30 meters will be just a little harder... all to make $.01 of electricity. I'm skeptical.
If I see someone shoplifting, it used to be a no-brainer to contact management. These days, I would weigh the hassle of spending an hour or more talking to management AND the police about what I saw and when I saw it since now I am a witness. Not to mention filling out forms giving everyone involved my name, address, phone..... Can I change "hour" to "hours" ?
To sum it up, even if it is the right thing to do, I would probably NOT report someone shoplifting.
Both EDGE and G3 are marketed based on speed, but this comes at a cost. I wonder if anyone has done the comparison on the basis of $/bit and included the lower speed "low cost" networks as well?
If rechargable vehicles become common, the "state" will be receiving less gas tax money. I am sure there will be new laws put in place to tax these electric vehicles (Probably in the form of higher registration fes).
I'm not trying to dis the concept, just point out that the payback times may be even longer than first indicated
Would you feel the same if ANYONE knew where your child was at all times? RFID is generally not selective and will respond when polled.... by the park RFID readers, by those in the stores, or by someone with a portable RFID reader.
Plausible scenario ?? I'm just pointing out that RFID is certainly a two edged sword.

Disassociate H2 and O2 from water, measure the energy. Evaluate how much you get back in 35% efficient burning
Why do windmills have 3 blades. Why not 50? Why not 1 ? Why not 2 ?
Expose film with active radioactive element (Americium) from a smoke detector

These are just the ones that come to mind at 10:00 on a Monday night. I'm sure there are many MANY more.

Somehow, only 1.1% of computers running Linux seems a little low. Does anyone else see this number as odd or have I just been on Slashdot too long?
I thought all TECO commands looked like transmission line noise .....

For a good reference describing some of the problems with RFID technology, check out the book "Spy Chips" by Katherine Albrecht and Liz McIntyre http://www.amazon.com/Spychips-Major-Corporations-Government-Track/dp/1595550208/ref=sr_1_1?ie=UTF8&s=books&qid=1220142206&sr=8-1 This has been our for over 2 years now, but the general public has no idea on the capabilities or consequences of RFID systems. Give it a look.

Why not make the battery pack capable of accepting AA cells. Then you would only have to drive as far as the next Walmart
