The Mercedes-Benz 'Cloaking Device' 163

Posted by Soulskill from the at-least-it-can't-fire-while-cloaked dept.
cold fjord writes "As part of its marketing campaign for the new hydrogen fuel cell powered F-Cell, Mercedes-Benz has equipped one with a cloaking device. They covered one side of an F-Cell with LEDs and used cameras on the other side to capture the view, which is then displayed on the LEDs to effectively remove the vehicle from the line of sight."

      Bah, I dont need a cloaking device, most drivers act like the cant see my car already.

      • The roof line of my sports coupe is below most cars' mirror level so I'm invisible to most of them. It's like the cloaking system in FreeSpace, except you only need to make the car less than 4 feet tall instead of spatially compressing it into a razor-thin blade.

      Spokesman: Frightening, isn't it? Suddenly, the idea of buying a car for the cache of a hood ornament seems outdated. In the 90's, you don't need a car to tell the world you're wealthy; you need a car to tell the world you're smart.

      Inside, the Chameloen XLE has everything you would expect in a luxury sedan of its class. Soft leather seating, a contoured instrument panel, and fine wood. But there's more - much more.

      Authentically distressed fenders give way to a partially padded roof of blistered vinyl. While under the hood, a simulated transmission-fluid drip whispers, "Hey, not worth the trouble." This is craftsmanship no one will steal. GThis is engineering for the inner-city driving experience.

    • in the subject box! fucking seriously!

      • Why? Are you incapable of following a thought from one line to another? And what exactly were you trying to convey when you used 'fucking' as a modifier for 'seriously'? Could you not actually think of the precise word to express your thought?

        • Because it's the SUBJECT box, not the COMMENT box. You put the SUBJECT in it, not your COMMENT .

          In regards to my use of fucking: It's not a "modifier," it's a fucking adjective - and in this usage it is well known to indicate amplified emotion (usually negative).

          English: do you understand it?

          • Actually, I believe that in this use the word 'seriously' is actually an adverb, as it is implied that it refers to an action (verb, in case you have forgotten), and since 'fucking' is used to modify (hence 'modifier') 'seriously', then it too would be an adverb, as generally any modifier of either a verb, adverb, or adjective is called an adverb.

            Hopefully by the time you complete your GED you will have the opportunity to study English grammar.

      I don't think it is quite that simple. Hydrogen moves the pollution from many mobile sources, cars, to a very small number of non-mobile sources, power generation stations. With all pollution coming from these stations there is the opportunity for remediation, capturing the pollution to prevent its entry into the environment. Doing so is expensive and technically challenging but plausible.

              Apologies for not being clear. I was comparing Hydrogen to Gasoline, only minor modifications to the internal combustion engine are needed and there is a 20%'ish improvement in power output.

              Reusing internal combustion technology is irrelevant in this bigger picture.

              You phrased that incorrectly. All electric is the long term. But there may be decades before such solutions are practical. In the short term the internal combustion engine using hydrogen, natural gas, etc is a practical solution to get us through the decades of R&D that are ahead of us.

          Coal power is awful, but there is no reason we couldn't use the existing petroleum style of distribution to move hydrogen (although blimps are more fun than Exxon Valdez!)

          • but there is no reason we couldn't use the existing petroleum style of distribution to move hydrogen

            Yes, yes there is. Petroleum is a liquid at normal temperature and pressure; hydrogen's a gas, and a particularly pernicious one to store and transport. I just don't know why you want to whack an extra step in there, with all the inefficiencies that adds, just so you can use your car to turn chemical energy into motion, instead of turning electrical energy into motion.

      • Even better hydrogen generation can be done where there is vast quantity of renewable resources. I'm not an energy expert, but in my imagination I see use harnessing energy from wave currents and using it to generate hydrogen, fill blimps and ship hydrogen to places that need power. And also there are a lot of islands that are geothermal hotspots with access to lots of volcanic energy and ocean water.

      • Hydrogen moves the pollution from many mobile sources, cars, to a very small number of non-mobile sources, power generation stations.

        In theory you're right. Unfortunately most of our hydrogen is made from natural gas using an energy-intensive process and what's more, we don't even halt this process during the day and just run it on wasted base load at night, it's just a steady industrial consumer like anything else. If we were using squandered load from power stations to make hydrogen at night we'd get it essentially for free, aside from occasionally making some new carbon electrodes. To make them last as long as possible you want to dis

        • Right, because all those care idling during rush hour (95% of a lot of car's use) sure are being efficient. Not to mention that gasoline engines are around 20% efficient in NEW cars. Then remember that electric cars, no matter what their source is DO NOT IDLE.

          • Then remember that electric cars, no matter what their source is DO NOT IDLE.

            Then remember that we're talking about hydrogen, not necessarily EVs. And even if they are hydrogen EVs, fuel cells have all kinds of their own problems. They have an optimal temperature which is high, for example, and which must be maintained. They are energy-intensive to produce, much as batteries are. Hydrogen fueling infrastructure doesn't exist, just as EV charging infrastructure doesn't exist. And so on.

        Living in a city causes a fair bit of damage to one's lungs due to the urban air pollution. I'd love if vehicle exhaust was merely water vapor. Also, I expect a single large, stationary powerplant can have far better pollution controls than thousands of relatively inexpensive and mobile vehicles. Furthermore, a powerplant can be located where its pollution will have the least impact on humans and the natural environment.
