> When you connect 2 9000 mAh cells in series, the resulting battery has 2x the voltage but the same mAh capacity. In parallel, the battery has the same voltage but 2x the mAh.
The relevant units are:
* Capacity (Q, in mAh, Ah, kWh, etc)
* Power (P, in Watts)
* Voltage (U, in Volts)
* Current (I, in Amperes)
* Duration (t, in mostly measured in hours)
And the relevant formulas are:
* P = U x I or Power equals Voltage(difference) times Current
* Q = P x t or Capacity equals Power times duration
From this we can establish that connecting batteries in series or in parallel will not change their Capacity. When having 13 batteries of 29000mAh, or 29Ah, you have 13 x 29 = 377Ah or 377000mAh. Connecting batteries in series or parallel does make a difference in voltage and current: a string in series will increase the voltage while keeping the current the same (theoretically, in practice you get less than the current of the weakest cell); a parallel setup will increase the maximum current while keeping the voltage the same (again, in theory).

Forests don’t make any sense, who’s willing to pay for them anyway?
Could this be even more capitalist propaganda?
To claim their future existence, the EU government really has to prove their usefulness for the EU citizens.
Politicians are chosen by the citizens. So the question could be rephrased to “how do we make a big portion of the world aware of the seriousness?”.
A web search for “how to convince your opponent” gives some great suggestions:
———————————————————— How to Convince Someone Ask them to share their thoughts. Match their type of reasoning -- if they're being emotional, appeal to their emotions; if they're relying on logic, be logical. Get them to lower their guard with a genuine compliment. Pose a counter-argument (without making them defensive). ————————————————————
This is quite counter intuitive: I would think that if you would tell the data and scientific method used to obtain the data you would be able to convince anyone, but not so.
Instead you have to open the discussion and have both sides on the table, which leads to ridiculous situations eg: a TV show gives a scientist who builds upon many years of research equal time to speak on some matter as a fancy vlogger with a quirky opinion.
The more noise you make the more you will be noticed. If people aren’t confronted with their actions, they have little chance to change their opinion and behaviour. It is important to be respectful while also making clear that change is needed, by each and everyone.
