Not speaking to the veracity of the statement but quaise answers this in a different article: "A lot of the challenges are the same as for oil and gas. The subsurface is an uncertain environment. The deeper you go, the more extremes yo

This is better conceived and more carefully controlled than the vast majority of the published research I see pouring out every week.

I am not averse to that but the cooling is an issue. I have the most excess power in the summer. From what I have read I cannot use exterior temperature air which can be 95-105 in summer. Is there any inexpensive water cooling setup for the

I have a solar plus battery off grid setup at one of my homes. My comment that is the top on this item ( https://news.ycombinator.com/item?id=40877337 ) describes what I did for my solar setup. Two years in, everything has pa

In short the article and conclusions are a total mess and made a nice attention grabbing headline with little to no substance. As someone that has built and managed clinical laboratories for human samples, I find this article from consumer

The panel strings are at ~500v so there are safety, fusing and grounding considerations. Pretty common electrical equipment and cable is rated for use at 600v. There are special locking water resistant connectors for solar panels called MC4

It would be for the completed battery units with BMS. You would have to install the batteries into the battery cases. It is a bit tedious but it was otherwise straightforward. The batteries are extremely heavy. I have always had good experi

This is in the american southwest so winters are very mild and the sun is still strong. Summer is the much more demanding part where AC is 90% of electricity use for the year. There would certainly be challenges in other locations but I thi

All of the quotes and interactions I had with the local solar installers were reminiscent of the used car lot if not outright fraud. I was able to do what was permissible myself and a regular licensed electrician did the rest. The equipment

That does not include the costs for inverters and other electrical system parts. I am not endorsing these vendors but I am happy with the result. My system paid for itself in less than 18 months. I have many years of experience buying from
