What about OTEC ?
What about Hawaii's "old" NELHA 220 kW Ocean Thermal Energy conversion plant off the Kona coast ?
OTEC solutions are apparently still alive in Hawaii, as a project and funding for building another more powerful OTEC plant off Maui's coast was awarded in 2010 to Lockheed Martin, and NELHA is aiming to build a second plant by 2014.

What's your zipcode?If you live in a place with low insolation (that's avg. hours of peak PV efficiency) and low average windspeed, then you have to have some water--a creek, brook, whatever--running through your property to have good chances of generating your own power needs.
But if you do have decent insolation and greater than 2mph average windspeed, you have options. If you can only do a roof-mounted wind turbine, then there is this:
If you have an average windspeed of greater than 8.5 mph then you could also do one of these units, which can be mast-mounted for greater than rooftop-level windspeeds:
Whatever works for you, it's worth considering that traditional, fossil fuel-generated grid power has and will continue to rise a lot for the forseeable future. For example the cost per kwh in the Pittsburgh increased 10% in the last year alone. In NYC, it's currently greater than $0.30/kwh for the end user. It doesn't take much of that to get your personal break-even under 5 years (not that long when you consider most people own their homes for 30+ years).

Are custom-made prosthetics for the disabled not 'noble' enough for you?
Ok. Here's something to make housing more affordable.
What else were you complaining about? Oh, yes. Humanity's presence in the solar system. Well, they've printed airplanes, so with a modicum of imagination, you can imagine printing space shuttles.

Re:All you need is one car.
I'm talking about inductive AC synchronous motors.
Please understand that "induction" and "synchronous" are two distinct motor types. Asynchronous AC motors use induction; synchronous AC (aka brushless DC) motors use permanent magnets. There are no "inductive synchronous motors".
GM does not use a permanent magnet motor. I linked to a GM site for you, where they quite clearly say it's an induction motor.
There are two machines in the volt. One is absolutely a permanent magnet machine, and I see conflicting reports on the web about the second (larger) machine. You linked to a dealer site that is overflowing with other errors, so far from authoritative. It may be an induction motor, in which case it would be the first modern example not descended from ACP technology.
The Leaf (and apparently the ActiveE, hadn't checked out their motor tech) are the only modern highway-speed EVs with permanent magnets in its motor. Is that clear enough?
Sure, but that's a lot of cars, and a far cry from your earlier claim that "Brushless DC motors are history as far as EVs go." You also overlooked GM's permanent magnet motor in the Spark, and practically everything coming out of Germany and Japan, with the exception of the RAV4EV (using Tesla tech) and an eventual induction-powered Prius.

Yeah, I'm not sure what they plan on doing about that. Seems like it could be a major issue. They might not even have a solution to that yet, although TFA seems to be thinking this is going to be used for Flash memory, rather than CPU transistors, which makes heat considerably less of an issue.

Re:Nice specs...but....
Are you sure? Macs are usually able to take larger memory modules than were available at the time of release.
He probably bought a pre-Sandy bridge MPB just over a year ago. Pretty sad for a not-even-18-months-old line to be limited to 8GB, but that's Apple for you.
It must suck so hard to be you
Anyone in the market for one of Apple's new Thunderbolt-equipped 2011 MacBook Pros would be forgiven for thinking the machines only support up to 8GB (2 x 4GB) of RAM since that's what's listed on the tech specs and is the maximum build-to-order option available through Apple. However online store OWC says the new 2011 MacBook Pro models can actually support up to 16GB (2 x 8GB) and is selling the 8GB sticks you'll need to make it happen.

Re:Bad press...
GM quality is mostly crap all around (though that's generally true for all US manufacturers), and they've got a long, long way to go beyond "innovative" ideas to demonstrate otherwise. There's not even a US car in the Top 10 most reliable cars, and not a single GM vehicle on the list. The price point is really just adding insult to injury.
And I say this as a die hard fan of the Corvette and GM muscle cars of the past.

What is going on
The journalist is making it harder to understand what is going on.
IANAP but here's how I understand it thanks to google.
First, 85 tesla have been generated for very short instants in the lab so the article is wrong in saying 60 tesla is higher than ever achieved.
Graphene forms a two-dimensional lattice surface like a chicken wire fence.
For each molecule of graphene a single electron sticks out from the surface.
These electrons are free to hop around to other atoms.
In fact they act just like particles that have no mass and can travel at 1% of the speed of light. These quasiparticles are called massless dirac fermions. A fermion is a particle with certain properties, the nucles of a helium atom being one kind of fermion.
Electrons travelling at relativistic speeds is not earth shattering since that is what happens in gold atoms too. But the point is the electrons are free to sweep through the lattice without hindrance, and that if you can control the way the electrons move, you can control the apparent properties of the quasiparticles.In 2010 Francisco Guinea in Madrid predicted that stretching graphene along all the axes of it crystal structure will make the electrons act as if subjected to a magnetic field.
http://www.gizmag.com/straining-graphene-creates-strong-pseudo-magnetic-fields/15891/
http://physics.berkeley.edu/research/zettl/pdf/386.Science.329-Levy.pdfIn July 2010 Michael Crommie proved the prediction, by growing bubbles of stretched graphene that stick up like pyramids from the platinum surface they were grown on. The electrons acted as if they were subjected to 300 tesla fields.
This technique works at room temperature.The paper mentioned by the OP talks about designer Dirac fermions which means that you can create quasiparticles possessing the characteristics you desire by simply moving atoms around so they make electrons move in the way necessary to make the quasiparticles appear to exist. You can thereby freely mess with simulated mass, electrical and magnetic fields, etc. which might be very useful.
http://www.nature.com/nature/journal/v483/n7389/full/nature10941.htmlThe technique used in the OP experiment is low temperature and nanoscale. But based on Crommie's work it should not be hard to imagine processes in the future that could allow similar structures to be built quickly on a larger scale.
This is an exciting a relatively new field of research apparently but breathless reports using terms like designer babies or designer electrons when it is really designer quasiparticles, and saying that the fabric of reality is being messed with, is just distracting and does not help people who are not prepared to dive into the actual research paper to find out what is going on.

Oil, Wind, SolarEveryone seems to be approaching this perennial debate the way they have for the last 40 years at least. The burly manly man argument that we need to drill, baby, drill! and kick some more a-rab butt, and the (implied) simpering eco fag take replete with squirrels and butterflies.
But this time other trends set in motion by the last oil shock that sent gas above $4/gallon may trump all that. If you've been paying attention the last 4 years, nearly every major car company has been working on and rolling out production model hybrids and EVs. Tesla, despite the scoffing ICE fans, has not only survived but is about to release its 3rd generation of vehicles. And what's more, EV delivery vehicles are starting to hit the scene; Ford is rolling out its own. Another smaller one called Mia has another.
The delivery vehicles are a significant one because if you could spend $1.34/60 miles to make your deliveries vs. $20/60 miles paying for gas at $4/gallon, 12mpg, you'd be insane as a business owner to not be all over that. Trucking is an extremely competitive business where fuel costs and the means to shave them are a major concern. And that's the thing, if delivery vans break the ice with commercial use of EVs, then you can bet the long-haul guys won't be far behind clamoring for semi-versions of EVs.
So, on the consumer and commercial fronts the options have developed to give everyone a real window to jump from the ICE ship. 2/3rds of American oil consumption goes to transportation, so if the price spike last time was enough to get people to abandon SUVs, then this time, if the spike is severe enough, especially in a down economy, we might all wake up in 2013 in an America where the oil industry is 1/3 its former size. That is the definition of a sea change.

Re:How "An Inconvenient Truth" can it get
The link at the bottom indicates that running one particularly large cargo ship supposedly pollutes as much as 50 million cars each year (likely a gross exaggeration but still worth considering) http://www.gizmag.com/shipping-pollution/11526/
Read what you link to. That article is about dirty bunker oil producing sulphur oxides and other nasty stuff. Obviously burning that produce much more poison than low-sulphur oils, or relatively clean gasoline. Which all has very little relation to the amount of CO2, which is what we're talking about. Cargo ships could burn cleaner fuels if they were compelled to -- near most ports they are.

Re:This device empowers criminals.I think the application (and ease of application), something the article didn't go into much detail about, will set the rules for that game. Quoted from the linked article;
"So far, the technology only works from a distance of about three or four feet (about one meter), although NYPD Commissioner Ray Kelly hopes that its range can ultimately be extended to at least 25 meters (82 feet).
The plan is for the scanner to be mounted on a van, then used on suspects who would otherwise have to be physically searched." ( - http://www.gizmag.com/nypd-portable-gun-scanner/21147/ )
If it gets to the point that a van is allowed to scan past clothing at 25 meters, at the whim of a policeman, I think that the 4th amendment implications are grave, however, I don't think it's infringing on the rights of CCP owners directly, as it would only help enforce a law - a law you could more astutely claim is infringing on 2nd amendment rights. (Welcome to the shall/may state debate!)
Given that I don't live in a state that issues CCPs to citizens, it's already a moot point. I don't carry a gun because it would be a felony to do so, and this only allows the police to actually start cleaning up the guns carried by those who don't worry as much about felony violations. (i.e. The concept works under the presumption that we're all supposed to be unarmed.)
"New York gives wide latitude to the county authorities in issuing pistol licenses. In New York City, a concealed pistol license is allowed by law, but detractors have claimed it takes a large degree of wealth, political influence, and/or celebrity status to obtain.[33] In contrast, many rural Upstate New York counties are effectively Shall-Issue in their licensing policies, and some rural upstate counties have policies that allow unrestricted concealed carry after one has obtained a state carry permit." ( - http://en.wikipedia.org/wiki/Concealed_carry_in_the_United_States )
Given that New York isn't completely may-issue solid it might not make the same amount of sense in application, and provides a glimpse into the de facto decisions of the enforcement on this issue - implications that may bother some gun owners in New York.
(It should be clear, but I wanted to make sure to mention, IANAL.)

fear is overrated
I was not a fan of Cowen's arguments in two episodes of Econtalk, but there was a lot about his TED talk Be suspicious of stories that I really liked.
The first was that overuse of the good vs evil story mode lowers your IQ by ten points.
The second was that over-reliance on the story "we need to get tough with

Cowen on the Great Stagnation
And here's the rebuttal, fresh off the press:
Ion Proton sequencer decodes DNA fast and on the cheapThe space program is big and impressive and you can pick up chicks by sneaking them into the JPL and letting them steer the Mars rovers. However, the entirety of the space program, IMHO, is bupkis in significance compared with sequencing the human genome and the era of proteomics now unfolding. Stagnation my ass.
In a terrorist society, only psychopaths commit crimes, of which there are plenty, as the society conspires to drive them to it.
What drives me nuts about this story is the tacit concession to escalationism. If you shoot at someone and later they stumble over your corpse, you can't say you didn't have it coming.

The Rochair is far from a universal solution. The biggest problem with it is that anyone without excellent trunk control is going to fall over forward on the "pull" stroke. This excludes many paraplegics or individuals with compromised trunks from using it.
Seem like you can order one for about $5K: http://rotamobility.com/rochair/index.html I suspect it's unlikely you can get insurance to assist in funding the purchase of one.
So it fills a niche, of able-enough chair/scooter users looking for mechanical advantage in propulsion, but don't expect it to replace the norm.

OK, sorry about that. I completely understand what you are trying to say but you're talking about what the patent system claims to be and what it should be, but the reality is it is not those things and Apple has continually abused that fact.
Oh and fuel cells in phones and music players have already been developed and produced: http://www.gizmag.com/go/4609/ and fuel cell cars already exist and are on the market (I rode in a fuel cell taxi two weeks ago!), so when you say "might be used to power your phone... or car" it's already here and Apple didn't do it.

Re:Oblig xkcd
You're issue isn't with electric or gas, your issue is with energy storage/refueling ability. How about a vehicle with electric motors that run off a gas generator? That would do exactly what you ask for and still be much more efficient. Sort of like how diesel electric locomotives work. The electric motors are MUCH more efficient that ICE's, so you use a gas generator to power the electric motors.
That is an idea I would be open to, though I'd be leery aobut it in a car I have to depend on every day to get to work. I don't like the added complexity and maintenance vs. the simple vehicles I currently own that are cheap to own, operate, and repair. I find the technology very interesting though and would consider a diesel/electric for my boat. Epic is the only boat manufacturer making sucha system for wake boats. Have a look:
http://www.boatingmag.com/boats/sport/epic-23e
http://www.gizmag.com/epic-23e-electric-hybrid-sport-boat/11107/
Epic has a truly usable design that can replace tradition gas wake boats. I'm not rich so I don't own waterfront property. That means I trailer to the water and will be out for 4-10 hours typically. It's not convenient to just go out for an hour or two due to all the work getting the boat ready, hooked up, towed to water, cleaned up afterwards, etc. It'll burn about 6-7 GPH and has a 46 gallon tank. So if I'm out all day, and go far from the ramp, say, down to the city to get lunch on the water, I might need to refuel. I can stop anywhere along the river and refuel quickly and easily. With Epic's hybrid design I could use the boat the same way... So it's a practical replacement... Granted, new wake boats are in teh $50k-$80k range and I could enver afford one. I'm sure the 23e is another $30k at least. The problem becomes figuring the break even point for someone who can afford to spend over $100k on a new wake boat. Will it save them money in the 1-5 years your typical new boat buyer will own it? Or is it cheaper for them to just run a conventional gas engine boat? If the latter, these hybrids will never get on the used market where guys like me might consider them.
Nautique has made an all electric towboat. While a neat idea, it's not a wake boat and isn't suitable to run ballast and put out a large wake. It's a slalom boat and can only do a couple pulls through a slalom course before needing to be charged for 4 hours. This is the biggest problem with electric vehicles. This type of boat would be alright for someone who lives on the water, typically takes a couple quick sets in teh morning before work or in the evening after work, and has a dock with 220v power to it (most places you can't do this as local government or Army Corps won't let you run 220v to your dock or shoreline, or have lots of restrictions on it). It's not practical for how the vast majority of watersports enthusiasts use their boats since it won't even get a couple hours from a charge. This type of electric vehicle is an expensive novelty.
I could turn this statement around and say, Oil/Gas might be ok for now, but they will run out. Let alone the environmental damage they are doing. So we can either spend the time twiddling our thumbs until fossil fuels are much more expensive, or we can start investing and researching in electrics now so that the time when they do 'get there' gets here quicker and we don't have to pay $10/gallon for gas.
I'm not worried about this. We won't run out in my lifetime and I think any environmental damage is overstated. It's a concern to me of course, and I deal with that concern by riding my mo
