Reading their other comments, they have about 1000m2 of garden. So using 5t over 3 years is 1/2 to 1/3 of the dosage you listed. They don't appear to be over using.
Yes, my comment was also an anecdote and therefore also not data. This comment is exactly what I was trying to show - anecdotes don't give a full or unbiased picture.
A repackaged phone with a quality headphone jack and physical buttons? I'd love to buy that (but unfortunately it doesn't seem to have a SIM slot)

This is inaccurate as a generalization - in the three jurisdictions I've worked in, they're round if they're newer than ~1990, and mix of round and square (or two triangles that go together to make a square) if they're older than that. The frame and cover are replaced independently from the MH structure itself so the cover doesn't tell you anything about the makeup of the structure.
Canada, under $4 cad per dozen which is about $3.20 USD. Saw about $4.39 when I was in San Francisco last month, I (perhaps wrongly) made the assumption that similar would be available elsewhere.
Might I suggest buying eggs from a normal grocery store or other alternative source? That's $7.33 per dozen and unless you have some very unusual situation, a dozen eggs can be had for less than half that price at a grocery store.
I've made about $1400 from delayed flights in the last 3 years
At that point you would have essentially 8" of solid concrete, so an R value around 1.5
Adding 3" of rigid foam on the outside (then waterproofing and siding on top of it) would bump that R value up to around 15, with all the thermal mass on the inside (which can help if there's large day-night temperature variation)
First reaction: the homes are solving the same issue (somewhere to keep people warm safe and dry), so the solutions will look similar.
Second thought: Almost none of the actual technology in a modern home is the same as a hundred years ago, from insulation to ventilation, even down to fundamental structure - balloon framing became platform framing, tongue and groove sheathing became plywood, wood shingles that would need to be scraped and painted every half dozen years became one of a dozen products that'll last a quarter century without maintenance easily. A stick framed house a hundred years ago would be lucky to have crumpled paper in the cavity as insulation. Communications cable, high R-value insulation, air exchange with heat recovery, water and waste plumbing, electrical, multi-layer building envelopes, water-tight foundations, ... the list could go on and on, but a house built today is vastly more efficient and useful than one built a hundred years ago. (If you're looking on the market, most hundred year homes will have had all or most of these features added over the decades, at much higher expense)
> it seems to me that an interlocking LEGO style brick would make things go up so much faster and cheaper…or at least make DIY more possible
If you told me I should make a house out of some sort of brick-style product, all I would see is a hundred joints where water could get in and cause issues. I'm not going to do it unless the product has been on the market and heavily used for decades.
No, surface mining doesn't "suck up and kill seabottom creatures". :)
More sympathetically: yes, surface mining can have habitat loss issues (i.e. land use changes), but the bigger issue erosion and sediment control, the management of which is a major component of any modern mine in a well regulated country. Maybe there are ways to mitigate subsea sediment migration, but they definitely haven't been studied to nearly the same extent as surface issues and mitigations
Note that the rammed earth there is being mixed with cement, making it in effect a lean concrete. Additionally, the column (?) is on top of a concrete footing, it appears from coloration to be a fairly normal concrete mix at the bottom, the top layer is also definitely a standard concrete mixture, the rebar looks like standard for something in a short building as that presumably is. Essentially the only difference between that and a standard concrete structure is that the column has to be much larger in cross section (as the lean concrete mix used would have lower compressive strength than normal concrete), the mixture uses less cement in exchange for compaction in lifts (i.e. exchanging material cost for labour cost), and the formwork has to be much heftier to sustain the pressures being placed on it from the pressure rammer.
I quite like the sturdier looking columns, and the layering is quite attractive (that guy clearly puts a lot of effort into it, visible when he's fine tamping the outside edge of the layer very carefully), but I don't think it's so much different than normal concrete. Trying to do QC or QA on that mix design would be a nightmare.

For me, having to press the LV button twice an hour seemed more preferable than flashing the firmware.
I'd also add that any sort of stream crossing will have pretty stringent restrictions for working in the wet - you're limited to time of year, weather events, need to maintain safe overflow at all times, fish passage, etc - all of these add cost, and limit how many people will bid on the project (they need to dedicate schedule time to the work - can't push it off a month because of delays on another project, or it'll take them out of work period).
I couldn't tell if it also requires the maintenance of road traffic at all times - if it does, even maintaining one lane at a time (with automated signals) would easily add $100k to the price (culvert needs to be removed and installed in sections, then extra work to join them together, much smaller paving operations, etc etc)
It looks like the kind of project that might work better cost wise if you could lump say 10+ replacements together and have a 3-4 year long project.
- Unit price contracts (much easier to track growth in cost, helps to identify and mitigate issues earlier)
- Vendor performance management (Contractors and consultants are given a score after project completion, shapes how bids are evaluated on future projects)
- Qualified bidders (contractors and consultants are evaluated beforehand, only allowed to bid on projects if they've done something of a similar scope/content before - ties in with the point above, smaller projects will allow bidding by contractors with less history/lower scores)
The system isn't perfect (since it relies on vendor history, it only works well with projects of scope and type that they do regularly - i.e. roads and sewers mainly), but it's a lot better than a simplistic "lowest bid wins"
