I am just saying what the typical install is in the South East US. The heat pumps installed may produce some heat at 5F but they can't keep the temperature to the set value, so there are resistive elements (Aux heat) to make up the sh

The issue with heat pumps is that most of the ones currently being installed in South East of the US don't work well below +20F let alone 0F or -20F. Most of them are being installed with an electrical resistive backup heat, which is i

I disagree with the cold part. It is easier to dress to stay warm in a cold place than to dress to stay cool in a hot place. Both adults and kids bike in Scandinavia in the winter. Here is a good video on it. https://www.youtub

Feels like there is a business case for people willing to pay to reduce trip times for trans continental flights. The problem is that the greenhouse gas impact will be higher for a supersonic trip compared to a subsonic one. This is on top

You can take precautions to avoid the oxidation. This is already done reliably on airplanes and in overhead power distribution, where aluminum wire is the standard.

There are also a new aluminum alloys (aa-8000) with better mechanical properties. The biggest issue is that that the trades/DIYers need to learn new processes. Treating aluminum wiring like copper wiring is a disaster. Also need to ove

On a personal level, this reminds me of a concept called normalization of deviance. [1] Every time we do something which we know may be risky, but we do not have a catastrophic result, we further reduce the perceived risk that the catastrop

Generally agree, although I think it is largely an illusion. Many people die in car accidents they did not cause.

Lithium Ion batteries degrade very little with low C mid range charge cycles. The time/temperature/SoC degredation is greater. Hence why you don't want to leave a battery sitting at 100%.

RoHS does not just restrict lead. It also restricts use of mercury, cadmium, and several toxic compounds.

This is so cool. Viable for LED lighting in an off-grid situation when there is little sunshine for solar panels.

It's a known hypothesis. Additionally when there is less traffic, drivers feel safer and are more likely to tune out by checking their phones, etc. The book,Confessions of a Recovering Engineer(1), talks about this. (1) https:/&

To me, Bungie is associated with Apple and the amazing Marathon game series for Mac back in the 90s.

Wish there was a way to block everything and whitelist allowed channels. There are some really quality ones but there are also a bunch of really creepy content, even in the kids app.

Saw this movie last night. One of the tougher movies I have watched. Being a satire, it exaggerates a bit, but still hits pretty close to home.

The HN algorithm will de-front page stories where the comment section starts looking like a flame war. If you look up the stories which were removed from the front page, there is quite a bit of toxicity in the comments. I personally like t

Found some articles claiming this but also others disputing it. France does not appear to get much Uranium from Mali.[1] Although I would not put it past them having an interest in future Uranium prospects. [1] "France uses some 12,400

If only the world would have followed Sweden and France [1] and largely de-carbonized their electrical grid by the 90s using primarily nuclear, we would be in a much better situation when it comes to global warming. [1] https://e
