Driveway detcord net

  [vote for,

Expecting heavy snow or freezing rain? Be prepared! Simply purchase the appropriate size of MaxCo. Detcord Net and lay it on your driveway before the freeze begins. Once the ice has built up, simply connect the trailing lead to the Special Box with the Big Button. Press the aforementioned Big Button. Repair windows. Job done.

       //Remove parked vehicles before operating.// We prefer the phrase "Parked vehicles should be removed."
MaxwellBuchanan, Feb 21 2019

       ... or they will be removed anyway.
8th of 7, Feb 21 2019

       More in the sense of "this should remove the vehicles".
MaxwellBuchanan, Feb 21 2019

       Loose snow wouldn't respond well unless you had really good coverage. So you'd need really good coverage.
bs0u0155, Feb 21 2019

       The solution to that problem is to pour on plenty of water until you soak the snow and have good reason to fire the net.
MaxwellBuchanan, Feb 21 2019

       Is this the moment to remind everyone that the pressure wave from such an assembly will be pretty much isotropic, with the snow overburden acting as a tamper ?   

       Or should we just leave it until after someone tries this on their expensive printed-concrete driveway ?

       Max - You do realise that your are now "a person of interest" in GCHQ by virtue of posting an idea that includes a certain combination of words?

       //Is this the moment// No, not really.   

       //"a person of interest" in GCHQ// I like to think I'm a person of interest generally. Or at least an object of curiosity.
MaxwellBuchanan, Feb 21 2019

       Listen out for strange clicks on your phone....
xenzag, Feb 21 2019

       Oh, I get those all the time. Bloody amateurs.
MaxwellBuchanan, Feb 21 2019

       ////"a person of interest" in GCHQ// I like to think I'm a person of interest generally.//   

       I assume we're all on some lists. Ticking boxes for knowledge and experience of potentially dangerous technologies, then ticking other boxes marked "Motivated only by gin" or "fanatically opposed to every single ideology".
bs0u0155, Feb 21 2019

       //"Motivated only by gin" or "fanatically opposed to every single ideology"// Proviso: must be good gin.   

       Also, conjunction error: 'or' should definitely read 'and', definitely, definitely 'and'.   

       The entire 1/2B is at the spiky end of the autism/gifted spectrum. Definitely.

       Might be more practical if the driveway is poured with tubes or sufficient porosity so it can sweat out a viscous liquid explosive of some kind. Of course, you'd need to figure out how to get only the stuff exposed on the surface to explode, not the stuff coming up behind it.
notexactly, Feb 23 2019

       [notexactly] alternate your explosive gel with a dense inert gel. To explode, force explosive out onto the surface. To reset, force the inert gel out to "clear the tubes", then more explosive gel (backed up by more inert gel). Would probably need a distribution of individual dispensers, rather than a "central" unit (unless you can rig all feed tubes to work exactly the same... perhaps if they were all the same length, regardless of final "outlet" position).

       //Might be more practical if ...// Do you think you could hold off on the innovation until we've recovered the sunk costs of the Detcord Net development project? I used the Intercalary's savings to pay for it, and he'll be very pissed off because he was planning to spend the money on a name transplant as soon as a donor became available.
MaxwellBuchanan, Feb 24 2019

       A major disadvantage of my version is that it'll take a lot longer to develop, so I think you'll naturally have at least several years without much competition.
notexactly, Feb 25 2019

       //alternate your explosive gel with a dense inert gel//   

       Yes. I was imagining a sort of grid of explosive lipsticks. Alternating explosive and inert stripes improves that idea a lot. But how did you propose to initiate all these point charges together, without setting off more than one layer at a time?
pertinax, Feb 25 2019

       Uniqnely addressable initiators embedded in the composition, at the base of each layer. The detonation initiates the layer above, the layer of inert gel below dissipates and attenuates the shock wave.   

       A multi-component inert gel, akin to the explosive lenses used in early gadgets, would give the optimum results.
8th of 7, Feb 25 2019

       Can I just make the general comment that [8th]'s use of the word "optimum" is not necessarily what you might think.
MaxwellBuchanan, Feb 25 2019

       Well, bun for blowing stuff up anyway.
