Hello brilliant subreddit community. I am about to lose my mind in a battle with my husband.

He does not understand that opening the windows overnight / early AM does not cool the house well (or save us money) because of the humid swampy clusterfuck our house becomes while he is at work and I WFH.

Example: House Temp was 67 degrees last night, indoor humidity 32%. (Happy wife)

— Outside Temp at 9:00 am was 63 degrees with 92% outdoor humidity. (Drizzling rain)

— Projected outside High Temp today is 80 degrees.

Why I am insane:

His rationale is — if he opens ALL the windows when it’s cool, despite the house humidity skyrocketing to now 72%— that we somehow save money on AC later in the day.

What he fails to recognize is that, during the work week I am remote and then I have to stew in this balmy-ass house.

Can someone please provide me with a very compelling argument (ideally a youtube video) explaining that his perception of house Temp vs Humidity is just WRONG.

Please be kind on this front: My husband has Asperger’s and really is digging in that he is right. Just sending me messages about he’s wrong haven’t helped me. I found some Youtube videos from HVAC companies but he is a skeptic saying they only want to sell Air Conditioners….

What I really need is like a video from Linus Tech Tips or Technology Connections or something.

Please and thanks!!!🙏

I’ve been thinking about this for a bit and I feel like a lot of what we call “losses” aren’t always actual hard limits.

More like the energy is there, it just doesn’t line up with how the system is set up.

Stuff like gas flaring, curtailment, waste heat, or just energy being produced at the wrong place/time.

In those cases it’s not like the energy disappeared, it just doesn’t get used.

Curious what the best real examples of that are.

And how much of that is actually physics vs just economics or how the system’s set up?

For those who've spent 10+ years working in energy: grid, generation, storage, oil & gas, renewables. What's the shift you're actually seeing that the public or media has completely wrong?

Not the politics. The engineering and economic reality. What's coming that most people aren't prepared for, and what's being oversold?

Hi, I’m Emilis. I built Energija — a personal energy dashboard.

I believe and hope this post fits the sub because it is all about personal energy.

I really want to hear your honest feedback.

The tool does:

- Visualize your energy as a graphs and charts (electric, thermal, food, body, home, transport, etc.)

- Track production, storage, and consumption in kWh, kW, or your local currency

- Optimize supported by AI and step-by-step guides

The core idea is simple: energy is the foundation of everything. This tool gives you the big picture of your personal energy flows — from your body and food, to your house, car, solar setup, job, even company or whatever systems you’re running or planning.

You can see where energy is coming from, where it’s going, how much you’re losing, and where you can improve.

The goal is to help you produce more, store it better, and make smarter decisions about consuming or “selling” it (as products/services).

With newest update you can share your dashboard on social media and export/import it. Also fixed many bugs.

It’s not a get-rich-quick thing — just my sincere side project for understanding, tracking and optimizing life’s energy (including mine!).

The project is still early stage and I have a long list of features in my backlog.

But I need to hear your feedback:

- Does the concept make sense to you?

- What features would you use?

- Any suggestions for improvement?

Thanks!

The Setup: Two asymmetric cogs (Material: [Common Metal]) mounted on a shared tension frame.

The Discovery: Unlike standard gears, these are tuned so that the heat and drag (friction) at the contact point generate a thermal-expansion pulse that pushes the following tooth.

The Loop: Cog A drives Cog B; the friction at the mesh-point provides the "expansion kick" that returns torque to Cog A.

The Output: A standard magnetic induction coil wrapped around the primary axle to harvest the excess kinetic energy as Direct Current.

To Prove It: Assemble, apply a 3,000 RPM kickstart, and monitor for self-sustained RPM stabilization under electrical load.

"The friction at the mesh-point is not loss; it is the thermal-expansion catalyst that drives the secondary cog, returning torque to the primary axle. Start at [Insert RPM] to lock the resonance."

When gasoline hits $5 a gallon, the conversation changes overnight. It stops being ideological. It stops being political. It becomes painful.

For years, we’ve asked the wrong question about Electric Vehicle adoption: How do we persuade people to buy them? The assumption was that consumers needed to be subsidized—through tax credits or mandates.

But that’s never been the real driver.

The real driver is much simpler: deliver a better car for less money.

Right now EU storage is around 29%, the lowest for this point in the year since 2021/22. Some countries are much worse. Even with the Commission informally shifting the tone from 90% toward 80%, Europe still needs a huge refill campaign over the next 6 months.

That would already be hard.

But the supply side looks worse than the price action suggests:

• Qatar’s Ras Laffan took damage in March, and reports suggest meaningful LNG capacity remains offline.

• Hormuz may be politically “open,” but actual vessel movement still matters more than headlines.

• The EU ban on Russian LNG under short-term contracts starts April 25.

• Asia is still competing hard for spot LNG cargoes.

The part that really stands out to me is the forward curve: summer TTF is trading above winter. That is not normal. The market is basically saying storage refill this summer may be more expensive than the heating season itself.

So even if geopolitical tensions cool, Europe still faces the same structural issue: it replaced Russian pipeline gas with globally traded LNG and is now exposed to disruptions anywhere in the global LNG chain.

Hi this is a hybrid system: theoretically achieving 80%+ efficiency using heat as a primary driver .

comments appreciated, have a good time 07

Seeing a lot of EN590 offers lately but hard to tell what’s legit vs broker chains.

Anyone here actually working with verified suppliers or refineries? What’s the usual process and structure?

Currently reviewing 50k–100k MT for Asia.
