Another factor increasing the earth's mass is global warming which adds about 160 tonnes a year because as the temperature of the Earth goes up, energy is added to the system, so the mass must go up.
How does adding energy result in increasing mass, unless you're converting energy to matter? Surely if you heat something, it expands, but that does not increase mass!
Well, unless you are an American in America or abroad (which the US can now bomb at will) or a foreigner in a war zone, you cannot be bombed without there being diplomatic repercussions.
But my point was even more subtle than that. One predator drone has enough firepower to take out the computing infrastructure. It is also easily boarded. Without UN recognition, it doesn't really exist. And it is unlikely to get any recognition before, and especially now.
My complaint may be a bit contrived in the instant case. However someone always suggests that "we could make Mars habitable by adding CO2" you really can't. Mars atmosphere is too thin, and will always be too thin.
What I notice that Venus is almost the identical diameter, to earth but has 93 times the surface pressure. When people talk about the "green house effect" they tend to mean capturing of solar rays by CO2. All of this is true, but the higher pressure means higher temperatures. PV=T and all that regardless of gaseous makeup.
I wish people would stop saying "greenhouse effect" caused the heating. It's simply not true. It is the atmospheric density and proximity to the sun which makes it so hot.
Venus: 93 bar surface pressure, 96.5% CO2, 460C surface temp Mars 0.00636 bar surface pressure, 95.3% CO2, -63C surface temp
Ok, I forgot to mention Drake, who is a lovely blend of wrapper and Canada's values. It's almost comical when compared to the US gansta/thug rapper image.
Canada is a colony of the crown, much like Australia. It is primarily a British-US culture save for some belligerent Frenchies in the East. Canada's original culture was North America Indian including Eskimos (Inuit), which have been marginalized by western culture. Canada's best comedies are take-offs of British shows (Canda's worst Driver) and their original stuff "Corner Gas" is marginally funny. (Kenny vs Spenny, Kids in the Hall, etc successes are short-lived) Anyone sufficiently funny winds up in the US (Lorn Micheal's, Micheal J Fox, etc) however these people are more "American" than Canadian.
Don't get me wrong, I love Canada. But the culture isn't original, it is derivative at best, copied at worst.
It's not about "electrically identical" Its about being able to walk up to something and plug in, and not having to carry 3 electrically identical but physically dissimilar cables around. You might as well give me a peg board and alligator clips.
Lets hope that whatever follows has the same longevity as VGA. In a world where we've invented USB 3 times (USB, mini USB and micro USB) with non-compatible connectors in just 11 years, the future does not look as good.
Granted lifetime EROIs need to make sense. Like having to drive a Prius 100kmi to break even on the production of a Prius. However you have to look at the peripheral benefits as well. If we were to reach 5:1 on solar (and I am sure we will) are there any reasons to switch? And the answer is yes, many. Distributed power generation reduces costs on maintaining infrastructure, it gets us off a chemically and politically volatile fuel yielding both chemical and political benefits. Now factor those back into the EROI, and you don't need 5:1, you might need 4.5:1 or 4:1.
So you have to be sure you're comparing all of the ROI, not just energy.
It's a completely different market, with different risk tolerances. Races are expected to have fatalities, and while not desires is an accepted risk. Cars are not the same.
But yes, my point is we need these designs in standard autos. Just adjusted for that market.
It has to be replaced. The only reason why EROI is so high is we're just lifting it out of the ground. There are a ton of ways to replace fossil fuels with passive processes. Look at solar panels vs natures version the leaf. The best leaves are about 2% efficient at creating sugars. Our solar panels are around 20%. Meaning our directed (engineered) approach is 10x the yield. This translates into 1/10th the time or energy input. We won't have lifting costs because we can make it on site.
No. Carbon fiber does not absorb impacts, it reflects them. or catastrophically fails (splinters).
If you were in a car with a carbon fiber unibody or frame and you hit something substantial the impact won't be absorbed. Assuming the frame didn't catastrophically fail, you'd immediately stop and bounce backwards. This change of speed and opposite direction would rip your organs apart and you'd die of internal hemorrhaging It already happens today in steel cars, however the steel frames and unibody have crumple zones that dissipate the impact over a short period of time. This reduces the impulse (3rd order d/t) and makes the impact more survivable. There would be little to no change in a carbon fiber car. The car would survive, you wouldn't.
While we need to find alternatives to fossil fuels (I care not about our reason - pollution, economics, or national security - any one is good enough for me) we won't get at the right solution without good old garage projects in a DARPA-style grand challenge. Only after we've had several designs on several aspects will we be able to get an improvement. Just look at all the effort and ingenuity into Pumpkin Chunkin!
Currently closed-loop steam looks like it might get a resurgence due to fuel indepenence, lack of stoichiometry, simpler design. We currently need contests in:
Materials design - Mostly making carbon fiber chassis that won't kill
Materials design - Alternative fuels & fuel generation
Two comments to your 3 comments. 1. Most websites are not "distributed" --skipping 2-- 3. I have been working on this (Wt/Qt hybrid) on my own and I call it Ct, or Cutie. It exists as a cutie.h file and some modification to the Qt MOC that will take the UI file you define and it will substitute the Wt includes and classes. It works! However there is a problem in that the ideal here would be a single file that you can just throw a compiler flag and switch between the Qt and Wt version. I've been working on this and it just does not work well, mostly because Qt has a "QWidget" which is both drawn and a container, and the Web does not have anything like that. (In theory you might be able to use Qt's Lighthouse feature (just released in 4.8) to produce a HTML5 canvas for the application surface). I think I can over come that. But the other challenge is that Wt uses boost and STL and Qt uses its own boost-like features and containers. This to me means Wt should be implemented in Qt (using only core, network, sql modules) However such an effort is beyond myself at this time. The resulting work could be LGPLd as it would be based off Qt.
Wt ("witty") is a C++ toolkit that is modeled after Qt. It uses boost and STL, but you get to use familiar Qt concepts - signals & slots, Model view, etc. Basically think of Qt-based web pages. It fully supports AJAX and can handle the data server-side or on the client. It also has a C++ -> JS converter so you can just make a function for conversion to JS and have it exec on the client. Of course it runs as a module, or it comes with its own server. It fully supports CSS, DOM, etc.
I reall like this approach because my two complaints of PHP: 1. It is unstructured 2. it is ugly (both syntax, and having code embedded in pages) are alleviated. 1. C++ object orientation encourages a structured approach. 2. The "it's 100% C++" ensures that you focus less on the presentation in PHP and just on the application logic. This helps encourage a model-view-controller approach. While you might have to write CSS, you will never have to write HTML and you won't ever have to mix the two in a CPP file.
Another reason is speed. Everything is compiled and runs natively, or compiled to JS and moved to the client. Yet another reason is security. Wt has several protections built in. See the features link below.
If you're looking to do web pages entirely differently, this is it.
You really are off to a horrible start. If you don't know enough about the mechanics already, you're just going to end up pulling a star trek and it won't be as believable as you want. "Pulling a star trek" is a modern version of dues ex machina, where you invent some technobabble to cause or escape the crappy lot device you constructed.

There are no retention laws on license plate scanners, toll booths, really anything. Most retention requirements are written from the stance of minimums, not maximums.
The Toshiba 4S seems like it would make an ideal neighborhood reactor. Plus, I love the design. Rather than using control rods to stop the reaction, the reflector enables the reaction. By controlling the radioactivity of the core you ensure it can never get too critical. And the reflecting band even if it gets jammed only enables a small part of the core to overheat.
It's not like Nokia phones are going to be any different from other vendors' WP7 phones, despite the privileged position Nokia has. Their real chance to be different was with the N9, and by all accounts the phone is a success in the markets it was launched in. People love it -- if they can get it. Carrier subsidizing is the only "feature" that is missing. But good news Newegg now carries it! ($630) so no dealing with shady importers.
I hate my Android, but I'll likely go back to iPhone, unless I swing the N9 for xmas. Yeah, I'm not even a year into the Atrix and I'm looking to spend another $630 because Android is crap. I prefer a "walled garden" to an open field of shit. I'm only waiting to see how the iPhone 5 changes things.

One fatal flaw. Easily declared an enemy combatant and easily bombed.
