It's a little bit more than the energy of a "normal" lightning, according to wikipedia^T^M One of the side problem is energy density. Your garage can deliver 6kWh at best, but it can't deliver 12kWh for 30min.

You are correct, but conversion from thermal to electricity is quite inneficient. and it represent 60% of global electricity production. So driving a tesla is more efficient IF it comes from renewable.

Thank you. I actually have to point that 25,000 TWh (I have the number of 29 PWh) is electric production only. global energy consumption is ~180,000TWh (a drop of 10,000TWh during covid, yay!), 85% of it is (c)oil&gas.

You're correct that the power required is quite big. It's actually one of the dead-spot in my comment. Supplying 135MWh for 37min is a lot. For example, the Jichuan Solar Park – China is "1,000MWh" and 90km^2 wide (I ass

which mean we can produce close to 3000T of steel in a year with renewable. (1,888 millions tons were produced in a year). The 5% is for all electric sources. I don't look at renewable only but any sources (and coil&gas makes a sol

Q: what is the fifth country that start with an A? I apologize for the oversight. Indeed, there are five countries in Africa that start with the letter "A": 1. Algeria 2. Angola 3. Benin (Incorrect) 4. Burkina Faso (Incorrect) 5.

Germany did investing, but China ate the market. It's basically what happened in the 21th. It's also interesting that we're talking about 1980/90. 25 years ago is 1999.

We're not able to left it in the dust today, how could we have done so 25 years ago? "we" should have, but "we" could not.

It's math time, let's look what wikipedia say about electric arc furnace: - 1.44 gigajoules (0.4MWh) is required for 1 ton of steel. In theory. - 300T of steel needs 132 MWh, and a "power-on time" (the time that steel is

in the mc Donalds movie, at the end one of the founders say that the reason they chose to include Mr Donalds, is because of its name that convey a "USA vibe". Also, why Apple is called Apple and not Macintosh anymore? I'm not

What I mean is as a worker or student, I want to know if the tools I spend time on will be relevant in the industry. And I think I have more chance to meet companies working with MATLAB than Julia. But if I want to work at asml Julia might

Tools are valid regarding a context (when you have a hammer everything is a nail etc.). In the industrial context, Julia is not valid. In the research/education, it is valid. It does not mean that Julia will never be relevant in resear

same. it's relaxing to the eye, the font is monospace I think, the colors are "calm" and it's not a wall of text. It's also fast to load.

Both I'd say. We consider it less than the thermal problem since there is less regulations about noise, and it's also part of how we build today since there is a tradeoff between price, sound isolation and even thermal isolation.

the problem in buildings is the building transmitting vibrations. That's why it's hard to find a solution afterward.

is it a big deal ? Any components need to pass some conformity tests, and testing capacitors is an established process. There are bike with supercapacitors out there, so it's definitly not that far from the market.

on a bike, we don't use hands to propell ourselves for obvious reason, why they don't also put a crank for the hands too? it double its speed and you can counter balance the legs motion too.

I don't see the shape of the holds being a big problem. With some help from indoor companies and hold makers, figuring out which hold model is on the wall should be possible. As for the usefullness of the software, I'm sceptical t

You don't want to put salt water in the ground. It will destroy either the soil or the aquifer.

The preprint is freely available, thre are nice pictures where you can see mm/cm-size magnet near the electron beam, over a "G-grid detector" that act like a test pattern in the background.

Doing so requires more than just specially designed lenses and sensors, Utsumi says, because no matter how well designed and built those components are, there will be imperfections. For instance, consider an image taken by an ordinary camer

Sure, but as you said, there is probably a need of a small crew up there.

One could bring oxygen up there, with a small respiratory assistance I think it could do the job. But doing it remotely is obviously cheaper anyway, for many reasons.
