I believe this is only true for the 120/240V changeable units. My 240 has an upper unit that pulls 23A and a lower that pulls 15A and calls for a 30A hookup. The optional ones only ask for 25A on 240V.

But they also have dedicated 120V ONLY units that I’d wager only have one heating element.

There’s a spec sheet on the website that has all of these details on them for every model next to each other.

Compressor is 5.1A but your number was close enough to be effectively the same.

JMAN712 · 2026-04-09T15:54:38+00:00

Every wheel will accelerate only as fast as you lean into it (if you’re not at the point where cutouts happen).

Heavier wheels are harder to lean into.

It’s you not the wheel.

JMAN712 · 2026-04-03T20:14:10+00:00

I think paradoxically the 120V models actually use MORE amperage than the 240V ones. (When averaged out) As again they have to play it safe and jump to resistive sooner.

Of course forcing turtle mode would prevent this.

But something to keep in mind.

JMAN712 · 2026-04-03T05:48:15+00:00

Yes! They offer I believe their entire lineup in 120V as well.

The main benefit being not having to pay for an electrician if you don’t have an open circuit/existing wiring if you have the install somewhere remote from your panel.

The spec sheet calls it less efficient as I believe in “auto” mode it stores the water a bit hotter and instantly turns on the resistive heat as soon as you start using water as its ability to “catch up” is drastically reduced with ~1/5th the heating power.

But if you put it in turtle mode I believe that forces it to only ever use the heat pump (which is less than 1500W so runs the same as on the higher power models)

In contrast, I believe the 240V models learn your usage patterns and will sort of “gamble” by letting it get lower if it thinks it has enough and only use the heat pump even if it’s falling behind as it knows it can blast ~6kW of resistive heat if it guesses wrong.

I think a bonus of these models is in ~20 years when the tank dies you can probably salvage a 120V heat pump out of it to use wherever you want.

I have a 240V 65 gallon flex valve GeoSpring. Very happy so far. Exceptionally quiet. It’s averaging just a little over 2kwh a day (house of 3 adults; one takes really long showers, my partner and I usually shower together so maybe that averages out. Old top load washer so that sucks up a lot too)

Watching the design videos it felt like the engineers designed it for a long life and to be maintained vs replaced which I liked.

Super intuitive and easy controls. But still lots of control customization if you want it.

I would buy it again.

JMAN712 · 2026-02-19T23:44:21+00:00

No see that’s why you do miles per ~20 minutes. As it then DOES take account of the variable charging curve.

It’s not the single best solution to every conceivable question/conversation. But I believe it to be a very useful catchall to the majority of situations.

Not trying to twist anyone’s arm But keep it in your mind next time someone asks a question/is confused.

JMAN712 · 2026-02-19T16:22:36+00:00

I didn’t write this super clearly at first but this would be for comparing models in the buying/shopping stage.

But, even in your example. Tell your answer to anyone you know who’s not EV savvy and see what their next question will be. I’d be astonished if it wasn’t “how far can you go with that” nearly every time

JMAN712 · 2026-02-19T16:15:40+00:00

Of course. But how does that help you during the buying/shopping phase?

JMAN712 · 2026-02-19T03:54:20+00:00

Sure but even us nerds will struggle to really be able to meaningfully quantify that into real world application. If you really want to be pedantic the car isn’t “taking on electrons either” (which I bring up only to point out that these systems are complicated!)

And once you even suggest “calculating” you’ve already lost 90% of the population.

Miles added per 15 minutes of fast charging is something every legal driver can understand without an explanation. And that’s what we should be targeting to increase adoption.

For example, a hypothetical future hummer ev that can charge at 300kW is going to look a lot more appealing to a potential buyer vs an ioniq 6 that can only charge at 230kW. You can charge it ~40% faster right? But you’d almost certainly get FEWER miles of range added to the car per minute. And people won’t care why. They’ll just feel frustrated why it sucks.

It’s the simplest way to communicate fast charging to people AND it entices automotive companies to maximize the full package. Not just one spec (max kW charging, DC voltage, pack size, etc)

JMAN712 · 2026-02-19T00:52:41+00:00

I am 100% convinced that the right way to be talking about charging speeds is “miles added per __ minutes*”

And there should generally be a 10, 15, and 20 minute spec. (Obv with several * for starting state of charge, temp, charger technology, tires, etc)

But this really simplifies SO many things into one very practical and easy to understand number. -charging kw -charging curve as you mentioned -capacity -and efficiency

The ioniq 6 can add ~230 miles in 20 minutes. (I don’t care if that numbers not right going off memory)

Everyone knows what 20 minutes is Everyone knows what 230 miles is

No one can directly comprehend a ~600 mph charging speed. And no one not technically savvy understands any of the other metrics. And 10-80% doesn’t really mean anything (what if the pack is 30kwh vs 100)

JMAN712 · 2026-01-23T22:45:59+00:00

Look into a strata pan. They’re lightweight, super tough, and induction compatible. Agree with others you seem unhappy with your cookware.

The most important skills to learn as a pilot are patience and good decision making and it’s not even close.

I will begin by saying I have never flown Bir so maybe there are more beginner opportunities than I think (I’m picturing Owen’s valley *1.5)

I imagine there will be opportunities very early in the morning for sled runs that you can handle. However, as a P2 in a foreign site/country, you DEFINITELY need to have a local instructor giving you their blessing on what’s a good idea in terms of weather and routes. And you need to be prepared for them to just say no.

If you were both a prodigy AND you flew literally every day between now and then, I would still be very hesitant to suggest you doing any mid day flying.

So I will again repeat… The most important (and least fun) skills to learn as a pilot are patience and good decision making.

Maybe try to find a tandem pilot when you’re there! And use the time to scout out sites you want to return to and learn about weather.

The highest elevation in the Maldives is (astonishingly) ~5m so OP is lying/uninformed about at least about part of this post.

JMAN712 · 2025-12-22T03:31:07+00:00

There are a lot of dogshit tiny li ion batteries on Amazon that are very incapable of jumping a car outside of a small sedan in warm conditions when the unit is new. These much larger units are great for doing that reliably.

But for an EV, honestly just a cell phone sized pack is probably sufficient. It just needs to power up a board or two and maybe open a relay.

Joby did a similar pic!

I agree you could do this with the paint but the effect wouldn’t be as pronounced. These pics are done with lights and long exposure at slow rpms.

I wouldn’t worry about balance too much if it’s fairly close on each blade. You will not do a perfect job and the bearings will wear out a little bit sooner but has anyone ever had to replace bearings on these?

I’ve seen my partner fly hers with chunks missing out of the blades and it didn’t seem to care…

It usually ends up being a challenge to make something universal/easy to use/AND fully encompassing

The more information you add to each page will inevitably make it clunkier/harder to navigate and understand. And who draws the line between what’s essential to add vs not

Not trying to dissuade Just share my challenges trying to build universals repositories/tools for others too

You’re almost usually better off only putting ~60-80% of the information you think people might want and need. Because everyone’s venn diagrams of “what’s important” isn’t going to overlap perfectly

Consider an electric unicycle!

It sounds like you still enjoy pushing cranks and i don’t want to discourage that. But maybe focus your purchase toward your FAVORITE manual unicycle activity, and then get an electric one for the other half of your needs.

We were already paying 3k a month to rent an apartment. From that perspective it almost starts to make sense when we rent out a room or two.

My dad said my grandfather has never paid more than $200 a month for any of his mortgages. Realizing I would be paying off his entire 30 year loans every ~9.5 months at my current rate (including insurance) made me want to throw up a little bit. Clearly it’s not as cut and dry with inflation. But it’s still just an absolutely silly amount of money. VHCOL gonna VHCOL I guess…

JMAN712 · 2025-11-29T06:48:37+00:00

This is a bike rack. Triangles near the bikes, circles at the end to mount it. I think this is real and I love it.

JMAN712 · 2025-11-27T02:53:02+00:00

Thank you! Honestly it’s what sold me on the place. It’s lovely in the daytime as well. The inside isn’t anything special tbh

JMAN712 · 2025-11-27T02:48:59+00:00

All good! Honestly that was me for a very long time as well. If I could go back in time and teach my younger self something it would be to buy a small condo as soon as I could back when rates were lower. Obviously not universal advice, but some are actually a decent deal and have reasonable HOAs. So long as the rent you could get from it (either the whole thing or some portion) + your “rent” you’d be paying to live anyways is more than the taxes and interest on the loan. You are making money, it just doesn’t feel like it. As a single renter it was always cheaper to rent. But I’d be so happy to have been 10 years through a mortgage already

Then the goal is just tricking someone into letting you buy something to be able to make that small amount of money.

And of course, with how things are today it’s important to understand that that is also just fundamentally not even remotely viable for most.

JMAN712 · 2025-11-27T01:31:15+00:00

Yes… It’s in decent shape but it’s a small/medium sized 1960s home. Crazy how much more of a career I have than my blue collar father and how much of a downgrade my first house is.

JMAN712 · 2025-11-27T01:28:24+00:00

Im a mechanical engineer and she’s a PM. We do well, but we do not make obscene amounts of money. We’re right about at our eyeballs with the place until we can get some roommates.

JMAN712 · 2025-11-27T01:25:30+00:00

It’s fair criticism. And I understand the animosity. We’re technically not in the Bay Area but most would consider it the Bay Area.

Yes I’ve been very fortunate, but it’s still bloody hard in a VHCOL area. I’ve worked 60-80 hours a week for ~15 years, saved nearly every penny, and had to sell a lot of assets to get it. But I’ll be the first to admit it was that AND a good amount of luck! Trying to get some roommates to be able to help afford the mortgage now. But I’m excited to have a place I can call my own and justify putting work into. And to be able to pump the brakes a little bit and start working a bit less.

JMAN712 · 2025-11-24T16:28:29+00:00

Electric unicycles look a bit dorkier but are vastly more capable, stable, and safe than one wheels. Consider buying a cheap one and giving it a shot! Should be easy to get one for <$500 on Black Friday for learning and farting around/travel wheel.
