People need to stop thinking chatgpt and any other ai's have actual intelligence or can give proper information or adivce.. they can't.

Chatgpt has no idea what it's taking about, it just spews out sentences that sound human like. You cannot trust any information or advice it gives you, hell you can convince it that 1+1=3

>GPS satellites have to regularly reset their clocks to stay accurate to earth surface time due to the relativistic time difference between the satellite and the earth surface.

This is not accurate, they use clocks that run ever so slightly slower

Don't know the exact number but roughly the scale. We are talking about a millionths of time going faster, so over 25 years.. maybe a couple seconds or so younger than we give it credit for.

It's not hard or difficult. It's just that clean water is really really cheap under usual circumstances. So using electricity to make clean water usually ends up costing more than the water is worth.

Seems like a strange concept to direct inejct hydrogen into a diesel motor when fuel cells will always have a higher efficiency without the need for diesel. Hydrogen isn't cheap, and it's made from either fossil fuels or from electrolysis. Even with electrolysis you are now losing so much energy that it's not very green(Even renewables emit co2).

Why not just replace with fuel cells?

Yea I work in the field.

Look we need hydrogen in the use of steel manufacturing and for fertilizers. These aer very very important industries.

There's 2 ways to get hydrogen. One you take fossile fuels, typically natural gas, and you get rid of the carbon to leave hydrogen. This uses a limited fossil fuel and is very polluting as the carbon turned into co2. Additionally anything that uses natural gas runs the risk of spills, and natural gas is a even worse greenhouse gas than co2.

​

The second way is to use electricity to split water. That takes energy of course, the energy that would otherwise come from fossil fuels.

We don't need hydrogen 24-7 and it can be stored. When we produce hydrogen it's transported in tubes under pressure, the tubes themselves act as a storage site and there's many other ways to store hydrogen. So you produce as much hydrogen as you can while the sun is shining and the wind is blowing and save it for when it's needed.

Another problem we have is that we need low carbon electricity to live our current lives without causing further global warming. A problem with low carbon electricity is that it typically isn't adjustable or reliable. Say you have a ton of solar panels to provide energy for most of the day. Well during midday our energy needs aren't that great, but the solar power is peaking. During that time we could use some of the energy from solar cells to produce green hydrogen.

​

If we gonna go low carbon we will have leftover energy to use for hydrogen production, and there's a big need for green hydrogen to further the low carbon efforts.

Garbage article

Yes green hydrogen is more expensive than dirty hydrogen right now. That may not always be the case, and even if it is, it allows consumers to buy with their conscience and brand their product as green.

Yes some places has shitty regulation. So what? That's not a hydrogen problem, that's a shitty regulation problem.

Green hydrogen is mandatory if we wish to reduce emissions from steel and fertilizer production, and it has many other interesting applications to be used in the future.
