What do you mean? All EVs, including the E-Transit this RV is based on, have heat and AC. People are already camping in vehicles like the Model Y, leaving the climate control on all night.
There's also typically ventilation to reduce moisture/condensation build-up in cold climates. Even with heat-exchange air circulation, the incoming air does require additional heating.
I mean that trying to heat with electricity is not feasible for a van. You need 2-4 kilowatt of heat to stay warm in winter. In summer, AC is another unsolved problem: most of these RVs hang in campgrounds on shore power because this is the only way to get consistent AC in warmer locales.
IME RV heat pumps are not worth much below around 10C. They’re okay to take some chill out of the air in temperate weather. The propane/diesel furnace is a much better option for heating below 10C.
What's special about RV heat pumps which makes them so bad compared to regular heat pumps? Heat pumps have gotten significantly better lately, and house-models are effecient down to -25C. Maybe the RV models you have tried are mostly older models?
RV heat pump are not that sophisticated because there doesn't seem to be much demand, they simply flip over to furnace. They are the same on the cooling side, they are no where near as advanced as a modern variable speed mini split.
There is no reason they could be more advanced with lower temperature support, they would just cost more. Many people put mini splits when making their own RV's because they work better and want to run off battery as much as possible.
What are you talking about. EVs can afford to have absolutely massive AC and heat for that matter because that big battery is multipurpose. Well big battery in good EVs at least, not in this prototype, but I’m sure they’ll up it if they do a real product.
And also, as you say, they will usually be on power (also because they’ll want to charge up for their next leg, which solar will not be sufficient for) so I’m twice over not seeing a reason for concern here.
I just own a camper van. In current state of affairs, heat is a solved problem with diesel. Air conditioning still does not have a viable solution, aside from shore power. You can't practically use electric for heating or anything really beyond powering the lights and the heater fan.
Most vans max out around 3kWth. I have seen people use a used Tesla battery, but only have seen one report.
I guess we are talking past each other. You seem to be expressing perfectly valid conclusions based on the current state of RVs, and I am thinking about what will be possible in the future when instead of a gas or diesel tank, some RVs will have a massive, massive, battery as current EVs do.
According to the Winnenbago rep that I heard talking when I saw it in person they are just working out the systems and design issues so they are ready when the range catches up.
This van had a 48v house battery that ran air conditioner and inverter and some DC-DC converters for step down from 400v traction battery to 48v house to 12v systems, they had the electrical system layed out on a board which was interesting. Most RV systems are 12v or 120v at this point in the US.
>Bigger issue is the current range limit of 108 miles
If that’s 108 highway miles, it would cover about 80% of my RV trips. Even when I go on a long trip, I usually don’t drive much more than 200 miles in a day, so with a charge stop in the middle, this could work even for a long trip. Assuming, of course, that I can find a DC fast charger so a charge stop is 45 minutes and not 8 hours.
But RV parks will need time to prepare and put in metered chargers, since most aren’t going to be able to handle many eRVs charging at 240v/50a all night long, many already have trouble keeping up with AC loads on a hot day.
Electric RVs would have tens of kwh of battery storage. You'd be able to run heating, AC, warm water, dishwashers, whatever for quite some time without charging. If you have a full charge and you really need 4KW, a 60kwh battery would last for 15 hours. That would be a really tiny battery for an RV of course. You'd likely want something a bit bigger. Maybe a 100kwh (25 hours) or even more. You get my point, it's not going to be an issue for most people. You can still plug it in or drive to the fast charger once a day or conserve a bit of power and maybe don't run the AC 24/7 on full blast.
12 kilowatt hours of battery storage gives you 3 hours of heat at 4 kilowatts. In 3 hours you freeze, literally (it's -0F/-18C outside, around Antero, Colorado).
12 kilowatt hours of battery is close 10 $10K in cost and takes 6 feet by 6 feet area and weighs 200lb.
Whatever you may think, in RV world:
1. Heat only can be done with gas/diesel/propane
2. AC consistently only on shore power
3. Cooking on propane
4. You will still be not living consistently in cold areas (like the Rockies) or warm areas (like FL).
5. Most of those long term rviers just hang on campgrounds for the electric power reasons (and sewer hookup).
So, electric RV is a dumb idea and will never be here.
Nonsense, it's already here. You can buy this or other vehicles like it. Or buy some electrical van and convert it.
Anyway, a lower end Tesla can be bought for around 40-50K. It comes with 60kwh of battery and they make a nice profit on them and you are obviously buying a whole car, not just the battery. So your battery cost argument is simply wrong
Cost of batteries actually dropped below 100$/kwh probably quite some time ago for them. So the cost for 100kwh battery would be less than 10K at this point. You are off by an order of magnitude.
These are not light vehicles obviously. But an RV is way bigger than a Tesla and you could probably easily fit 200kwh of batteries in there. Or more. Which is nice for range but overkill for just running the AC or heating. People drive EVs in the arctic circle in Norway. -18C is a nice warm winter day over there. You'd want the heating on, obviously. This is not a problem. It's a solved problem.
The new tesla semi probably has close to a mwh. I think the F150 has 130 kwh and you can run your house on it for days.
Most electric vans have around 60-70 kwh. Which is pretty modest and enough for a modest range. And yet it's plenty for a recreational vehicle although a bit limiting in range probably. If you are going out camping in extreme conditions, you might want a bigger battery than that. But otherwise, it's completely fine for recreational use for normal people as is.
60 kwh at 4 kilowatt gives you 15 hours of heat in a van in cold weather. Granted, you may not need full 4 kilowatt of heat at all tines, so let's say it's one full day. You drive to BigSky Montana to ski and after two days your RV is frozen solid, including all the water and everything is dead and leaking. All you can do at this point is to try and find a shore hookup or an EV charger. But of course the batteries won't even charge because they are too cold.
I’ve used a Prius as a heated camper, sleeping in the back. Doesn’t use much gas and it’s very comfortable. The motor comes on sporadically.
Ever since, I’ve wished for a hybrid RV that was basically a gas powered generator putting power into batteries, running the drive train when you need to move and powering everything else (heat, ac, computer, etc.) when you’re parked.
For whatever reason, no such vehicle seems to exist.
Yeah, it’s unfortunate that it hasn’t come to market. Ford has the eco boost 3.5L engine in the Transit but not its Powerboost hybrid cousin from the F150. It would be an ideal engine for a camper van.
The US rockies region get to negative F all the time. The area around Antero Reservoir gets to -20F -30F all the time. Winter Park overnight parking is commonly around -10F overnight.
Camping in a car is not an issue at all. Living in a van or an RV is an entirely a different game. For that you need from 2 to 4 kilowatts of heat, for days on end. If you let the temps inside drop below freezing even once, you are dead, all the plumbing is frozen and batteries are out of commission until you warm them up.
Solar is useless in winter. Finding shore power is hard.
There are solved problems in van life and unsolved ones. The heat is solved with gas/diesel. The AC is not solved at all.
As far as the range, I drive a disel van with a range of 400+ miles. It's okay but often times I wish I had more.
Forget it, EV RV is a dumb idea and is never coming. It does not mean they won't be selling one. There's always a sucker to buy.
I've slept in my Model S a number of times at -20°C at 1000 m altitude in the Dovre region of Norway. It's not merely possible it is perfectly practical and plenty warm enough while not really using very much range.
One does not need heat to sleep in a car (slept dozens of nights at ski resorts). This does not mean that you can heat up a van/rv with electricity.
(I have lived for a month in a van in Montana/Colorado/Wyoming. Camped in a Forester for months all over. Lived and worked in a van for 30 days in PNW in spring).
What a strange idea to build an el camino (unibody pickup) for a flagman ev by a company... It is not a good pickup. It is not a good SUV. Why? Because Ford sells a lot of pickups? But Ford pickups are actually useful as pickups, Rivian is not.
Many people and myself included, would love to see Lake Powell drained. It serves little purpose and we would be better without it. As a bonus, we'd get wonderful Glen Canyon back.
I am in the same boat as this woman, probably got a few good months left. I am planning self deliverance with helium as soon as symptoms become significant. For now I am just checking things off my bucket list and trying to have as many adventures as possible (I am an outdoor adventurer and a software engineer).
I know a larger than life man who is now very old. Years ago, he assured me that he would go the helium route himself, as soon as he realized his mind was slipping. I wouldn't be surprised if I hear that news any day now, although it would be quite sad news. He has many grandchildren and great grandchildren, and thousands of people like me that had the pleasure of knowing him. Perhaps you two will bump into each other in a spiritual realm, and swap stories of sailing and computer history!
Laughing gas is nitrous oxide (N2O). I'm talking about normal atmospheric Nitrogen (N2). Nitrogen is available anywhere and significantly cheaper than Helium. Nitrogen can be used for welding or for brewing certain types of beer.
What an outright evil thing to say to someone. I think you do yourself, and, whatever religion you may have been indoctrinated into a great disfavour by not actually learning about your faith.
Most religions don’t actually forbid suicide anymore than they forbid a lot of other things like wearing leather pants. The fact that organised religions still make it more tabu has a lot more to do with controlling populations through faith than what is actually written in your religions texts.
And it's always about how others should live. I'm perfectly ok with people deciding for themselves that they want to live by scripture x, y or z but then they invariably want others to live by their scripture as well.
I'm not religious either, but a better analogy for a believer would be telling someone to pray or sacrifice a goat to stave off scurvy.
If you really believed some nonsense, sure you'd want to not keep it to yourself, and to tell others how to live. But that wouldn't actually be a good thing, despite the believer believing it was.
You twice used examples where a "believer" has (at least observational) evidence to support that belief.
Some of organized religion has roots in that (some of the Jewish dietary laws have practical basis), but much of the prescriptions of organized religion is preference-based rather than evidence-based.
Are you talking about the same religions that exists on planet earth? because in our earth suicide is prohibited even in many non-religious Ideologies.
It's one thing to feel with the pain of others, but another thing to glorify or defend things that shouldn't be.
The Christian bible doesn’t condemn suicide. Most of the mentions were written in a period where society didn’t combine suicide with something inherently bad. Even in the more recent parts you can see Mathew praising the suicide or Judas because it was better than living with the guilt.
Obviously organised religions have found ways around what’s actually written in the bible, and you won’t have a hard time finding Christian’s who think that not killing includes yourself. That is an interpretation though, and unless God spoke to you personally to clarify it, then it’s frankly a lot worse for you to judge someone than to leave that sort or stuff up to God. Even if you are on some misplaced quest to save souls then Jesus already has you covered by dying for your sins.
Contrary to what you may think I don’t have a problem with religion, but I do think people who use religion to spread hurt are assholes. Considering that religious texts were written, selected and curated by people I frankly think it’s on the individual to interpret them. If your interpretation leads you to harassing dying people then you should stop and become a better person instead.
Whatevs. Joe Rogan, as far as I could tell is some sort of loud macho redneck type that does not have anything interesting to say.
On another note, Spotify is so buggy an application I am surprised how/why anybody is using it. The most common thing is that it crashes on my iPhone. I was considering buying it, but not after discovering how bad/buggy it was.
Canister stoves that produce a small amount of carbon monoxide have an unfortunate feature of making more CO with increasing altitude. Watch out: a stove in a tent that was perfectly fine at 5K feet becomes a source of CO at 8K feet.
If they were backpacking, I'd say carbon monoxide from a stove most likely. Otherwise maybe only lightning makes some sense. All this "toxic gasses" seems way too unlikely.
Classic example of "I can't think of a use, so it must be useless". bc is very useful, and I can think of several times one might need a command line calculator.
Commands like 'arch' might provide a limited amount of data from a different command. However, to extract just the data from the larger response would then require a string of grep/sed/awk. or call the one command to give you the output you specifically need. This also holds true for the 'uname' section.
I use dc all the time, which the article denounced as even worse. dc gets more usage on my machines than most other commands, except for perhaps ls, cd, and vi. Whenever I need to make quick calculations on my computer, it is much more efficient for me to open up a terminal window and type dc than it is for me to use a GUI calculator or to grab my HP-48 graphing calculator. I suppose I could use a Python or Common Lisp REPL, but I love Reverse Polish Notation: less typing!
Yeah that one was really weird. I mean I personally usually start python or some other repl when I need to calculate something but I have reached for bc/dc sometimes aswell.
And what's with the jab against RPN? The author should probably try some FORTH to learn how nice and minimal code in postfix notation can be. I'm guessing he doesn't like LISP either...
Me too, although R has become my command-line calculator of choice for most tasks. Being able to calculate things without moving my hands over to a calculator or calculator app is convenient.
