Due to limitations of the SMTP protocol, we have access to the following email metadata: sender and recipient email addresses, the IP address incoming messages originated from, attachment name, message subject, and message sent and received times.
One thing must be remembered: Even Proton must follow the law and rules.
First known electric car was built in 1837. Yes, 1837, not 1937. In 1910’s and 1920’s there were tens of thousands electric cars in USA and Europe. So electric cars has been here for a long time right now.
First (known) solar panel was built in 1954.
