Freestyler_3··on Electric heat storage (Night Storage Heaters) (2019)
Why heat your house when the sun does that already?
Freestyler_3··on Solar panel waste may not be as bad as we thought
Panels come with 20/25 year warranty that after that period they have declined a maximum of 20% in performance.

If you have the liquids with the properties to handle that you could. To make it easier you would have to halve each next heat pump specs, so that the earlier pump can deliver to both the condensor and the evaporator.

What about one way barriers?
Freestyler_3··on Day ahead electricity prices for EU
But the UK has HVDC line to norway right?

dark roof helps on cold days right?

No, not all high voltage is above ground.
Freestyler_3··on Wet/Dry Vacuum Buying Guide (2019)
I remember being confused how kitchenaid and competitors calculate how strong they are. The machine has a HP rating and a Wattage, the HP was higher than the wattage when converted. So after some reading it turns out they have a special way of measuring HP. It still confuses me.
Freestyler_3··on DRAM thermal issues reach crisis point
Don't you want to have AC running on cooling mode or dehydration mode to get water out of the air?

edit: this makes me wonder what is the ideal humidity in a data centre? Is too dry a thing?

Freestyler_3··on I disabled WiFi on the new Samsung fridge
My wallet is a faraday cage.

No reading my cards without actually taking them out.

Freestyler_3··on Human genetic engineering is coming
I think for future space travel we need genetic modifications.
Freestyler_3··on I Accidentally Deleted 7TB of Videos Before Going to Production
From his story I can tell he found one big mistake. The tedious work itself.
Freestyler_3··on Making traditional light switches smart
Philips hue also has these modules for wall switches, so you can use your standard switches.

Or in my case I use non-latching switches and then can cycle through scenes or use it as a dimmer.

Freestyler_3··on No, you can’t save £30 per year by switching off your “standby” devices
The efficiency is higher than input because the electricity is only used to transfer heat from one spot to another. This is when the gas gets compressed, to get to the condensing stage at the high pressure. (+after burn for optimal efficiency)
Freestyler_3··on Ask HN: Am I going insane or is there genuinely no value in blockchain tech?
If you have digital cash, you might want to spend it somewhere. Services tailored to work with the system from the ground up, then later they can be absorbed into conventional companies.
Freestyler_3··on What science says: Could humans survive a nuclear war between NATO and Russia?
That would have to mean that ALL nukes are on launch sites ready to be deployed.
Freestyler_3··on Elon Musk makes $43B unsolicited bid to take Twitter private
People will bail who bought on the good news PLUS people will bail who hear the bad news but didn't buy with good news.
Freestyler_3··on What science says: Could humans survive a nuclear war between NATO and Russia?
I would assume most nukes are small tactical nukes. Initial nukes will focus on nuclear launch facility's, command and control.

So I think a significant amount of nukes will not be used at all.

Freestyler_3··on Young women earn more than young men in several U.S. cities
Turning more into reddit.
Freestyler_3··on Big-box Stores could slash Emissions, save Millions – Put solar-panels on Roofs
Not every flat roof can hold all those solar panels. You don't want the roof to collapse when the first snowflake drops.
Freestyler_3··on Heat Pumps for Peace and Freedom. Joe Biden Could Damage Putin Badly
As much as I advocate heat pumps, claiming they are "affordable" is not true in my eyes.
Freestyler_3··on Chernobyl power plant captured by Russian forces
I think a nuclear bomb and a nuclear power plant are very different and have different halftimes.
Freestyler_3··on Anyone else feel the constant urge to leave the field and become a plumber?
The amount of knowledge you need for residential is minimal, there is only one voltage (ok maybe multiple phase) and you should only have to think of load per circuit. Don't know what kind of intuition you really need for new install.
Freestyler_3··on New York City bans natural gas in new buildings
It is nice when a few houses do this in a neighborhood, but when more do it then the electric company is going to get challenges that come with the high demands of power.

Electrifying everything in a whole city will come with very expensive infrastructure changes. Especially if every house can also be a supplier so the amps can ramp up in different cables every time

(Also wow, your solar panels are expensive. Is that inc. Battery? I put down 4kw systems for about 3-4k 10x400wp panels)

Freestyler_3··on My Bose QC-35 II headphones burst into flames and left me with chemical burns
That is assuming it is from the burning materials, but OP said it happened when he was peeling off the earcups that he noticed it being sticky etc.(so it could be the plastic mixing with chemicals?) And we do not know how many ppm of toxic materials were in the fumes he inhaled or his wife inhaled.
Freestyler_3··on Scientists find a way to ‘catapult’ rockets into space like ‘slingshots’
Also that size vacuum chamber is challenging to say the least. edit: like how will the seal work?

Freestyler_3··on Scientists have found a way to harden wood to make a knife that rivals steel
This is why you don't wipe glass(es) with paper cloths, micro scratches will eventually make it look like sanded glass.
Freestyler_3··on With corporate tax off table, U.S. Democrats turn to billionaires
middle class buys a 500k house, which is more than they have. wealthy people buy a house but it is only a fraction of their wealth. Proportions are different Simple thing as food too, they might eat more expensive but if you look at it they only buy food for 0.01% of their wealth and middle class 10%. (fictional numbers but roughly this is how it is)
Freestyler_3··on With corporate tax off table, U.S. Democrats turn to billionaires
700 billionaires stat mentioned (they have 5000-6000 billion) 200-250 billion tax income

That is a 5% tax estimate on total wealth, if you take the percentage of actual wealth increase then it is much higher.

To be honest a fixed percentage tax would then be better because it will force them to invest, too big percentage and they will have to take risky investments, and forcing people in that corner is not good.
