It is does not. LCOE is a metric from the Lazard institute has been debunked many time alreayd because it does not take into consideration the cost of the capacity guarantee of the grid. If you had that, Nuclear become competitive. If you h

I am half surprised. People are often shocked when they discover the real number about the Carbon intensity of the German electricity production. There is years of green washing to digest before accepting the truth.

Exactly. The main problem with the EU is that it is an entity with a construction aborted half-way. The EU parlement is a example of what the EU should be. The EU commission is not. The EU commission was literally intended as a temporary f

I would not bet on it. But there is pretty low constraints on what you can do and can not with an NFC chip. Your budget in term of compute and memory is extremely low. I would be surprised a proper RSA/ECDSA signature from an X509 cert
