????. New PV modules can get their energy payback after less than a year or two. Since they keep running for more than 20-25 years, you don't need much time to understand that at least from energy POV, it's all ok. Then, recycling methods get better and better, and the cradle to cradle life cycle is already damn good. What's your problem?
Solar thermal collectors are even more interesting. Why the hell do we need nukes or coal/gas/whatever to heat water a few degrees and take a shower?
It goes on and on, but to make it shorter:
geothermal A/C = good, but only as free cooling. Better yet, don't use any A/C!
geothermal heat = depends on your electricity grid, but always better than electrical heating
basement nukes = just plain stupid. Nukes are interesting for central +++GWatts, to power industries and trains. For any other purpose, use local PV/biomass/windpower/geothermal power plants.
bigger car = bad. Buying a bigger car is a 0-win game. You get a bit more security, but you put every one else in danger. If every does so, everybody loses, especially the environment.
having more than one car = very bad.
flying = very bad.
the more I research it, the more it seems that there is nothing you can truly do to reduce your carbon footprint, even if it seems logical
I think that what I wrote shouldn't be too surprising, but maybe it could help...
To keep improving your carbon footprint, you could eat less meat, buy less tech products that you'll throw in a year, and you might end up with the carbon footprint of an average European!;)
This is specially true when comparing oil's energy content to any other alternative!
At least in Europe, we now have to work half as much as 30 years ago in order to buy one liter of oil.
But those damn tabloids keep on selling millions of copies just by telling gullible readers that "Oil has never been so expensive".
It might be a bit more expensive than a year ago, but it won't prevent me from thinking that we still see far too many lone guys driving SUVs downtown.
This is where we start to understand that our species has performed a fantastic "power breakthrough" when domesticating fossil fuels : with 1 euro (which is about 1 dollar, Wall Street specialist will excuse me to concentrate on magnitudes), I can buy 1 litre of petrol (or gas), that contains about 10 kWh of energy, which is about the equivalent of two "slaves" working for a full day. And oil would be expensive ?
Yeah, yeah.... we know that, "The American way of life is not negotiable", and all those BS!
The trouble is, the only thing that *really* isn't negotiable on Earth, is the quantity of resources that we can use. Mankind population, quality of life, life expectancy, GNP are just fragile parameters that some droughts/flood/wood fires/diseases/air pollution can easily disrupt.
Plus! In a environmentally-virtuous society, you can win in local jobs what Middle-East states lose in petrodollars (less cars=> more bus-drivers, less malls=>more small shops in the center, less coal-power plants => more PV/windpower-technicians......)
Meanwhile.... Germany is still the 3rd dirtiest country in Europe according to gCO2/kWh(el). "Atomausstieg" and Windpower are just lame excuses for the 4 big concerns to keep burning cheap coal all around the place, and for a looooonnnnggg time.
Real "Öko-guys" should be fighting a bit more for a better energy mix, which would imply keeping some of nukes up and running.
I was talking about everything except MP3: videos, photos,flac, ogg, wma...
You're just doomed to use twice as much storage (and to lose quality) as soon as you use some of those formats. I just don't understand how they can decently propose you to convert 7MPix Jpegs into shitty Gb databases files. Isn't that frustrating?
Oh! And that you need to choose between "Music storage/Data storage" for Shuffles. Isn't that stupid? Sure you can use some python script, copy your music files, install python interpreter on your host, launch the script and listen to your music...
It's the most frustrating tech piece I've ever seen. It sure looks good, and when you have media on it, it "plays for sure", and it does it decently. BUT you need to convert everything to some weird format before you can even try to upload. You need twice as much storage at home. You need some special software to copy anything on it, and the output quality isn't half as good as what you get with other devices (take a look at IAudio's...). I still don't get all this hype!
Those dispersed devices are called "humans". And those actions are sometimes described as "stop taking planes", "don't buy this SUV", "put a jumper instead of heating your house to summer temperatures during winter", "don't eat too much meat", "move your ass and stop waiting for a technological miracle" or "understand that American/European way of life actually is negotiable".
Anyway, you cannot produce "cool", except if you find a way to release excess heat outside of the atmosphere (e.g.: an open fridge actually heats our planet, but putting the condenser on the moon would cool it down). Global dimming has already been proposed as a "solution" to global warming : spreading so many small particles in the atmosphere that a part of solar radiation would be directly reflected. But this simply cannot work because particles end up falling down after a while (hours/days/months, whatever) while global warming will have long-term effects (centuries at least). To actually counterpart global warming effect, you would have to keep increasing local pollution.
Coming back to your example, you obviously can use wind's work to increase internal energy of the atmosphere, but I doubt it would have any significant influence compared to the 10**17W that earth receives from the sun. It's much more "efficient" to keep on releasing CO2/CH4/N2O/SF6 into the atmosphere to increase greenhouse effect.
We're not talking about work created using an application, we're still talking about derivations of an app. It's just that this app is a web-thingy app, and will never be "distributed" to users, but will just provide some kind of service to them. So that according to the GPL, devs are not obliged to release modifications they made to the code, and can get away with the "free beer" part without caring much about the "free speech" one. As always, if this license doesn't suit your needs, don't use it. AGPL is no more "viral" than GPL is, it's just appropriate for "free as in free speech" web-apps development.
And with all those dirty power plants (more than 40% coal & 20% gas) that exist in Germany, your "damn cool car" would release even more CO2 than those Mercedes/BMW/Audi.
Nice improvement indeed!
Sorry guys, you'll have to choose between "Atomausstieg" and electric cars!
Submitters, please either bring us crapload of algae/hybrid/electrical/fuel cell/ethanol/biodiesel/thyme-powered car stories, OR X-wing/SUV/flying-car ones, but not both.
It justs doesn't make sense to prone energy-efficiency on one hand and use barrels worth of oil for stupid stuff on the other.
Thank you.
Sorry I forgot to mention thermal collectors. True, they are easy to produce and have a huge energy payback. Let's put them everywhere!
PV modules still have a rather high CO2 output mainly because they are produced in Germany or Japan, that still have a pretty dirty electricity production (Coal++, Oil++, Nuclear-- => 700gCO2/kWh). Produce them in France, you'll divide CO2 output by ~8!
So you get a lot of advantages from PV modules (at least for decentralized needs): you don't see them, don't hear them & they (could easily) produce less CO2 and produce electricity 5 meters away from where its needed with virtually no risk/maintenance.
I obviously still think that nukes are useful/compulsory, but as long as it makes sense to replace some of them by PV, we should just do it! I'd rather have modules on my roof than nuclear wastes in my backyard!

You're right! USA & Israel don't threaten to eradicate anyone, they just do it!
The US are still the only country that has ever used nuclear weapons.
Go live in the Gaza strip, Irak, Afghanistan or Lebanon before saying that US/Israel don't eradicate any other country!

From qalculate:
sigma*(5778K)^4*4*pi*(1.392E9m)^2*29ns*1% to J
= 446.3 PJ
ans/c^2
= 4.966 kg
Conclusion: maybe, maybe not.
You "just" need to convert 4.966kg in pure energy in 29ns!
