Yes those benefits can now be realized now with modern controls. Back when the Saturn V was designed the control systems necessary to manage 30 engines didn't really exist. Digital control was in it infancy and was only really implemented with a backup on the whole Apollo stack.

Trying to manage that many engines while technically possible with controls of the era (check out the N1) means your control system would be introducing reliability issues instead of adding fault tolerance through redundancy.

Spray foam doesn't remove the need for a designing a proper insulation and moisture barrier system for the building. If you spray foam an interior wall with closed cell foam you most likely will add something to allow the other side of the wood to breath.

Choosing where your moisture barrier line lies is typically easy in new construction but does get tricky with retrofit situations. It sounds like the biggest issue from the article is that they are taking what were vented attics and converting them to non-vented attics with spray foam. The issue isn't really the spray foam, the issue is converting an attic without proper understanding of venting and moisture barriers.

It depends on what type of spray foam you use. Closed cell foam is rated to be a moisture barrier. It tends to be more expensive but is worth it to get a moisture barrier and insulation in one. In some scenarios where you need much thicker insulation to hit your desired R value they might start with closed cell for the moisture barrier and then switch to open cell since it is cheaper.

A major lesson of home ownership is that it is a continual fight against water. Keeping water away from places you don't want it, and keeping water in and available in the areas you do want it.

The would be the whole reason of it making the list. Most people would think it was named after the country or something not Mr. French.

$48 would require some pretty large order quantities and probably low end cells.

Currently that is the lowest price I can find for a cell at low quantities, that puts it at $62 to fill the pack which is not too far off. Looks like you would need a 33% discount on those cells to get to $48 which is within the realm of possibility if you purchase in large volumes.

To get a decent quality samsung cell you are looking at $118 to fill the pack. https://www.18650batterystore.com/products/samsung-30q

Yeah that was the main driver for me ordering a Ford Maverick. I has an Hyundai Ioniq before, and a BMW X3 before that. I am well aware of what can be moved in a sedan and an SUV, but it is much easier to move those things with my Maverick. I renovated most of my bathroom with Ioniq, but had to rent/borrow vehicles to get drywall and such. I recently finished my kitchen with my maverick and was able to move everything with that. Also it was 31.5K new and gets 40 mpg on average, the only real compromise was the lack of AWD. Which I make up for with snow tires.

The Canoo looks pretty awesome. If ends up being good, it will be a decent competitor to the Ford Maverick. I will say though that they did the same trick as the VW Buzz. They extended the windshield down to the very front of the vehicle, but the driver is still sitting behind the front wheels.

So VW mostly "got rid of" the crumple zone on the VW Buzz through visual styling.

If you look at that picture you can see the steering wheel and the drive is behind the front wheels. They just extended the front windshield to give the same look at the older vans.

I recently demoed an old hot tub that came with out house which ended up having a bunch of mice nests in it. Took it all the transfer station then just hosed all the mouse poop out of the bed out afterwards, and was able to help a friend move a couch the next day.

The biggest advantage of a truck bed is the separation of the truck bed from the cab. I can haul mulch, or the nasty rotting wood from an old hot tub in the bed without getting the rest of the vehicle gross. Another advantage is unbounded height constraints, I recently got a heat pump water heater for my house and they recommend keeping them vertical because of the compressor. So I was able to strap it upright in the bed which isn't possible in an SUV.

Sure you can haul a lot of stuff in a mini van or SUV but largely you run the risk of ruining the interior which I would prefer not to do in my vehicles.

Largely automakers don't make a lot of long bed trucks because they don't sell. Ford/GM/Ram all make long bed trucks but they only really sell for fleets.

But if you check out the Ford Maverick you can put 3/4 of a ton in the bed, and you get modern safety features.

So most likely that is focused on hydronic heating systems. Personally at my local home improvement store all the fitting in the plumbing section are listed as potable/lead free.

If you have some examples of fittings that you are referring to I would be interested. I can only really find hydronic circulator pumps that are only low lead instead of lead free.

It depends on what else you have available. If you have natural gas available at your house then a heat pump is probably not the most economical choice. Here in New Hampshire though NG is not available at many homes and a cold weather heat pump ends up being the cheapest option versus heating oil or propane.

USB 3.0 isn't really necessary to support higher charging speeds that is mostly through Power Delivery which I believe both the regular 15 and pro support since they both advertise 20W fast charging.
