2. For fuel-air bombs you don’t need to carefully mix the fuel and the oxygen because it uses the oxygen in the surrounding air genius . Thats how some of the thermobaric bombs work , an explosive on the inside explodes rupturing the casing of the bomb , when it does this it disperses the fuel into the surrounding air and ignites it as well . Additional oxygen is quickly sucked in and then the whole thing explodes outward creating the shockwave and the fireball . The moab which you compared it to does not function like this as it uses a pre-mix of fuel and oxygen .

3. If I have not explained this in a way that you can understand then just go to a store and get a full propane tank , a flare , some electrical tape and a couple 12 gauge slugs . Tape the slugs to the flare with the slugs just at the bottom of the flare , now you have a very crude detonater , tape that to the nozzle on the propane tank with the shells pressed against the section where the tank joins to the nozzle . Light the flare and run , when the flare burns down to the shotgun shells they will go off and puncture the tank allowing the propane and air to mix creating an explosion . A very crude and primative thermobaric bomb .

4. You do know that there are a wide variety of explosives that can be used don’t you . There are explosives that can work under water or can be vaccum sealed to remove the oxygen and still work or you could just use some binary explosives that don’t require oxygen at all to detonate . There are a wide variety of explosives out there not just the simple light the fuse and run variety .

All that you have proven with your claims that it has to have a pre-mix of fuel and oxygen or it won’t work , is that you now less about explosives and fuel-air bombs than I now about flying a space shuttle .

AND like I said if there is not a proper fuel to air mixture, I don’t care how much explosives you have, its not going to explode and ignite the gas. Its simple. No oxygen, no boom. Its like lighting a coke can filled with gas, its only going to burn on the outside of the can, not the inside. OR for a simple exercise you can do at home without dying, Get a 2 liter bottle, put a model rocket engine igniter through a hole in the cap and seal the hole with silicone, then fill the bottle with Acetelyne and screw on the cap. Get to a safe distance for no reason and detonate the igniter and watch with amazement as NOTHING HAPPENS. This is the same premise you are proposing on a much smaller scale. Jesus, now go and face palm yourself.

Thermobaric explosives rely on oxygen from the surrounding air, whereas most conventional explosives consist of a fuel-oxygen premix (for instance, gunpowder contains 15% fuel and 75% oxidizer). Thus, on a weight-for-weight basis they are significantly more energetic than normal condensed explosives .

In texas there are a lot of natural gas pumping facilities located all over the country side and most of those have several storage tanks that can hold thousands of gallons of the gas . These facilities often run on their own generators due to their distance from any power lines . Also the tanks don’t require power to store the gas , they do require it to pump the gas into a transport truck if it doesn’t have its own onboard pump which most of them do .

Also since to my knowledge no one has ever even attempted this in real life I wonder how you can be so sure that a thirty foot long forty inch wide bomb can be more powerful than a four story tall building that is almost two hundred feet long and a hundred feet wide and filled up with highly flammable gasses . Plus the explosives that are in the the building would not only disperse the gas but it would ignite it as well .

In this sci-fi book a town was on the verge of being over run and the citizens and remaining military personnel decided to go out with a bang . They went to a multi-story brick building , sealed all the places where gas could leak out ( cracks , vents , etc ) , busted holes in the floor and walls to increase air flow , placed explosives at every window and then pumped the building full of propane gas . This turned the building into one giant fuel-air-explosive . When the advancing enemy hoard busted in through the door the only person inside detonated the explosives and the building went up in one giant fireball that leveled the city and took out the enemy and the few remaining human fighters before they could be devoured . This blast was so big that at first it was mistaken for a nuke going off .

There are several buildings in my area that could be used for this mass disposal of enemies . If there ever is an outbreak of zombies I would have to try this one out . To draw the zombies away from the area that I would have to prepare I would use the sirens on police cars , ambulances and ice cream trucks to draw them away from the building , they would need to be remotely turned on and off to lure the zombies back in later . I would then need to bolt a metal plate over the outside of every window and vent on the first floor to prevent them from getting busted out by the zombies and then put a crap load of cualking around the edges to make it as air tight as possible . Next I would need to seal shut all but one of the doors and use cualking to make it as air tight as possible along the frame of the door . Next I would have to smash some holes in the walls and floors to maximize the air flow between floors , then set off a lot of smoke grenades that give off colored smoke to find any cracks or other openings that I may have missed earlier , then seal any remaining openings . Place a small generator on the roof along with a scavenged air raid siren which can be activated remotely to draw the zombies in later . Then set explosives on the windows , doors and in the various rooms to insure that the gas will be ignited when the bombs go off , daisy chain them all together to get them all to go off at once . Set up a detonater of your choice to set the bombs off when the only remaining door is pushed open by the zombies . Now bring in a large number of transport trucks and begin pumping a few thousand gallons of propane gas into the building . Now place vehicle sirens within a few blocks of the building to lure all the zombies back into the area . Activate the sirens and withdraw to a safe location , once the zombies are packed into the area around the building remotely activate the siren and get out of there . When the building explodes the ignited gas will rapidly draw in the surrounding oxygen and then explode outward , the extreme heat of the blast and the shockwave created by it will destroy the zombies and the surrounding buildings creating a massive kill zone .

The idea that blood loss would not effect a zombie is flawed as per my previous statement, that unless you are dealing with magic zombies, they would require blood in their body, as well as a working brain, in order to maintain body functions enough to remain mobile and dangerous. This is yet another reason that shrapnel could be effective, at least in slowing and then eventually incapactating large amounts of zombies. Besides HE and shrapnel grenades and mines, there is also WP (White Phosphorous) grenades like the M15 (commonly known as a smoke grenade). They produce a small area effect of over 5000 degrees for around a minute, and then the leftover WP particles have the potential to reignite if left dry.

The idea of brains only destruction of zombies is silly and does not follow known biological information on humans. It might take a bit longer, but if you destroy a zombie’s heart so it cannot pump blood, eventually its muscles and nervous system will shut down, and then eventually it’s brain, thus causing the “death” of the zombie. It’s time people started taking a more realistic view of that portion of zombie fighting, instead of the silly and uninformed “only the brain works” mentality pushed forward by most silly hollywood movies.
