    You realize that banning CFC’s did have massive implications on industry right? Most CFC use was industrial. This comment really just shows that you’re clueless on the history of this issue. Consumer air conditioning was far from the only casualty. If we had not banned CFC’s then the ozone layer would be in an absolutely dire state today.

    The Montreal Protocol is literally proof that if international governments wanted to they could come together and stop industry from destroying the planet, and you think we should roll that back for air conditioning? Give me a fucking break dude.


  • That we should go back to knowingly destroying the ozone layer because the lingering effects of our previous attempts at destroying it haven’t gotten completely better yet and that has had bad effects on air conditioning. Won’t anyone think of the poor deprived people forced to sit in their cars that are a sweltering 70 degrees Fahrenheit?



  • Voting is the absolute smallest political action anyone could ever take. Protest always has been and always will be more effective at moving the needle. Above all else these ghouls want to preserve capitalism. If it looks like the only way they preserve capitalism in the near term is capitulating to the demands of environmentalists then that is what will happen. Of course in the long term capitalists will attempt to erode these gains just like they have done with social safety nets in various countries for largely the same reasons (increased rate of profit).




  • You may already know this, but this depends on the focal length of the lens. For example, a 50mm focal length on a 35mm camera will represent objects in the background fairly accurately. Larger focal lengths have background compression, making their background look closer than it actually is. Focal lengths below 50mm will have the opposite effect, making backgrounds appear further away.

    Some phones with multiple cameras have a 50mm (or similar) effective focal length lens as one of the options. Basically without knowing the focal length of the lens it’s hard to say how accurately the distance of the background is portrayed.


  • I can’t speak to the superconducting potions of this comment, but the general computing information is mostly correct.

    Switching losses are a result of capacitance in the circuit. These capacitances aren’t going anywhere in transistors made from semiconductors. Additionally, even when a transistor is on it has some resistance, which of course creates heat whenever a current moves through that transistor. Leakage current also generates waste heat.

    I could see room temperature super conductors being useful as replacements for bus lines in a digital circuit, but this wouldn’t eliminate the heat in the circuit. Most of the heat is created in the transistor junctions, so the effect would be very minimal if even noticeable.


  • A lot of these cars are starting to get massive touch screens too. I’m looking at buying a Prius and several of the trims have a 12 inch touch screen. Why would I ever need that as a driver? Why would I ever possibly want that? Pedestrian and cyclist deaths keep skyrocketing and we continue to out these massive screens in cars that in many cases can’t be turned off. Lawmakers really need to make auto manufacturers responsible for the part they are playing in enabling distracted driving.



  • It’s mostly bullshit. Certain types of emissions create particles that reflect sunlight away from the earth, thus masking some of the warming that we have created through green house gas emissions. Banning sulphur emissions isn’t the cause of the problem, greenhouse gasses are. Banning sulphur just made our observed warming closer to what our actual warming is.

    You’ll find people making the same claims about transitioning to electric cars accelerating warming since cars produce similar particles. It’s just maintain the status quo bullshit passively enabling the continuation of oil and gas. The solution isn’t to keep burning certain types of fuel because it masks our warming. Obviously the solution is to stop producing as much greenhouse gas as we possibly can.
