tfwiki.net/wiki/Prepare_for_Departure"Prepare For Departure" Robots in Disguise (2015 series) original US air date: 23 September 2017 The bad guys are taking temporary shelter inside a warehouse belonging to a company that deals in pool supply items. For some stupid reason, the company is warehousing containers of raw, non-diluted hydrochloric acid (an ingredient in pH-balancing material) alongside product that is ready for shipment to customers. This is discovered when a canister is knocked over during the battle; it hits the concrete floor, cracks, and begins leaking acid all over. Well, in order to prevent more canisters from falling and cracking, one of the Autobots grabs a bag full of already-inflated pool floats and throws everything over by the shelving unit. The toppling canisters drop onto the floats, where they land perfectly. They don't bounce. The canisters don't crush the floats. They land perfectly.

tfwiki.net/wiki/White_Lion,_Run! "White Lion, Run!" Beast Wars II original Japanese air date: 8 April 1998 The Destrons have recklessly used explosives to clear a section of jungle so that they can begin constructing their base. This sets off a large-scale forest fire, which the Cybertrons are hard-pressed to fight as none of them have dedicated firefighting equipment. One of the Cybertrons, Bighorn, uses his buffalo mode to spear a large, downed tree with his horns. He then runs at full speed, driving the tree before him in what appears to be a crude effort at making a firebreak. This actually buys everyone enough time for Scuba to locate an aquifer and force enough water from up underneath the ground to flood the affected area. So - could you create a functional enough firebreak by using a downed tree to clear things out in such a fashion? Note that while the episode can be found online, due to some of the content issues (like one Cybertron literally trying to pee on the fire to put it out) I'm not posting it so as to be compliant with board rules.

bulldozing firebreaks is a thing. I doubt they showed it accurately on the show, though.

But can a downed tree take out upright trees.?.
My guess is your going to need something far stronger than a tree to bulldoze even a tree of similar size to the one downed, because the first big thing you hit will make matchsticks of your tree?.
Thing is, the roots of a tree are well capable of supporting the whole tree upright, in a much stronger fashion than maybe we give them credit for, in anything over 20 ft, especially near the base, and up to almost ten foot above the root, your at the strongest part of the tree in that zone?. They can take the full impact of hitting them with a speeding car, and just shrug it off with minor bark damage.
Managed forests in UK have built in fire-breaks, which just happen to make good access paths/roads, because making one in a hurry is a LOT of hard work.

Exactly. You can dozer a small tree, you may even get away with a larger tree with shallow roots, such as a Pine, but large trees... its easier and quicker to cut the tree down and deal with the roots later. For dozering them, if you topple the tree, tree and roots on the side, the roots are sticking up.... What you got that can climb over them roots "At speed"?.. And then as you go, with a "Flat" blade of a Dozer, you are making a pile of trees in front of you, either you got a BIG blade and a LOT of push, of by the time you got say 20 medium greater than 30ft tree's, you have a wagon load that needs over 600bhp to trailer out, but you got all that on front of you, and are running out of horses to push with?. Even if you have a wedge shaped blade and push the tree's to one side, the standing trees will resist having all that pile up on them, and will block your passage?. At a guess,, about half a dozen trees in, you are going to start to see what the problems will be, after three or four dozen, your going to start thinking "we are going to need a bigger boat", maybe halfway up or down the hill, you are in a heap of trouble surrounded by fresh kindling. Which raises a question I didnt think through yet... There is at the time of writing a huge forrest fire in California isnt there?.. SoCal wildfire NBC newsSo here is a question, you need to create a fire break in a hurry... how?. Can we here come up with anything?. I am going to go with taking a large load of C4 and sticking a lump to each tree in a line roughly 50 yard wide... This is just a starting point. Can you round up a few dozen men with chainsaws and let them have a go?. |

Can you round up a few dozen men with chainsaws and let them have a go?. how fast do you need it? that is what the tanker drops are SUPPOSED to be for. yes, you can use them to snuff out spot fires, and yes, you can use them to paint the ridgeline for the media, but the strategic use is to make a band of less ignitable for your fireline team to come in behind and start moonscaping. a fireline team typically has one or two sawyers and a whole bunch of guys with hand tools. C-4 is not so good, because as seen on Mythbusters, it tends to produce kindling. the biggest problem they are having in California, right now, is that everything there produces sparks, and the compression winds are blowing the sparks a mile or so ahead of the fire. there isn't much of any way to make a mile wide fireline in a hurry. |

From what I understand, at one point California also had an issue with the various local, state, and federal authorities blocking efforts to clear dead undergrowth and other such matters that could have made fires that much worse. Since one of the common reasons for blocking these efforts was "such-and-such endangered species may be living there", it was used as an argument against the Endangered Species Act through the 1990s and early 2000s.
