It would actually benefit Mixin Messenger's Users, if their communications were not misleading.
Image 1 appears to show that the desktop app has a "crypto wallet"
Image 2 is the documentation - which you'll only read if you're a guy like me. Otherwise, you would be given the run around to install the desktop app, then the mobile app - which is needed to run the desktop app - before realizing that the desktop app does not have a wallet!

🚿⚡ Can you generate electricity from municipal water pressure?
Yes — it’s called in-pipe hydropower. I did the math:
💧 A typical household tap at 60 psi and 10 liters/min can theoretically generate:
🔋 ~67 watts of power
🛠️ Realistically: ~30 watts usable (50% efficiency)
Sounds cool, right? But there’s a catch:
❗ It only works while water is flowing (shower, faucet, etc.)
❗ You could restrict your water pressure
✅ But yes — it can power a light or sensor in the right setup
🌍 Cities like Portland, Oregon use this to generate electricity from water mains!
Ha!
If you have 5,000 liters of water stored 30 feet high, you can get:
➡️ ~124 watt-hours of potential energy
➡️ But with 50% efficiency (real-world losses), you only get ~62 watt-hours
That’s enough to:
🔋 Fully charge a laptop once
💡 Power a 10W light for ~6 hours
📶 Run a Wi-Fi router for 3–4 hours
To power a 50W laptop for 8 hours (400Wh), you’d need:
💦 ~32,000 liters of water falling from 30 feet every day
🎯 Assumptions:
Laptop power usage: ~50 watts (moderate usage)
Time: 8 hours
Required energy:
50 W×8 hrs=400 Wh/day50 \text{ W} \times 8 \text{ hrs} = \boxed{400 \text{ Wh/day}}50 W×8 hrs=400 Wh/day
💧 Let’s reverse-engineer how much water is needed from a 30 ft (~9.14 m) drop:
We’ll use:
E=m⋅g⋅h⇒m=Eg⋅hE = m \cdot g \cdot h \Rightarrow m = \frac{E}{g \cdot h}E=m⋅g⋅h⇒m=g⋅hE
Where:
EEE = 400 Wh × 3600 = 1,440,000 joules
g=9.81g = 9.81g=9.81, h=9.14h = 9.14h=9.14
m=1,440,0009.81⋅9.14≈16,113 kg (liters)m = \frac{1,440,000}{9.81 \cdot 9.14} ≈ \boxed{16,113 \text{ kg (liters)}}m=9.81⋅9.141,440,000≈16,113 kg (liters)
⚠️ Adjust for 50% Efficiency:
16,113×2= 32,226 liters/day16,113 \times 2 = \boxed{~32,226 \text{ liters/day}}16,113×2= 32,226 liters/day
✅ Final Answer:
To power a 50W laptop for 8 hours/day using only water falling from 30 ft, you’d need:
~32,000 liters per day
That’s about 32 large water drums (200L) falling from that height daily

This kid has been branded as "right wing", but i find no evidence of that. His approach is Socratic and very respectful to people who don't have the same views as him.

But it does not fly...
🧪 BitBanana v0.9.5 re-verified as functionally reproducible!
We updated our methodology to confirm resources.arsc differences via apktool-decoded res/ files — ensuring no functional mismatch.
📲 Details:
When using the diffoscope tool on the apk pairs, i would find this result.
What does it mean? idk
So I took another path and used apktool to extract the contents of the apk pair in their own respective dirs,
and ran `diff -r` on each.
There was no result.

Review of BitBanana: Bitcoin & Lightning (verdict: sourceavailable)
Im a bit of a prepper and dont want to cause alarm to anyone. I was also a boy scout. I know we are also far from the conflict but here some helpful tips just for any situation : have some extra clean water supply at least for a few days. If possible invest in a 3 stage (or more) water filtration system. Have a "go bag" ready. In case comms go down (cell internet) have one of those cheap old school battery powered radios. A simple emergency medkit, at least alcohol, betadine and cotton.
Spain had a recent blackout, 2-3 weeks ago and they were mostly a cashless society. So they had problems withdrawing, etc. They also had a lot of terrifying fake news. For some reason people like to share bad news during times of calamity. An example of the fake news in Spain during the 24 hour blackout was - the Russians were invading! Which did not seem plausible but nevertheless was used by unscrupulous individuals.
When comms are down, have a designated meetup point if your family is all around. The primary residence is ok, but if circumstances force you to abandon, have a secondary safe space that everone should know prior to any emergency.
We have grown so reliant on the internet that losing it seems to have "blinded" many on how to go about without it.
Again, this is only for informational purposes, nothing to worry about, but always be prepared in prayers and in the physical world. Have a pleasant and restful Monday evening.
This is helpful.
