After 60 years of R&D, analog quartz consumes only 1 or 2 microwatts. (vs Apple Watch 10,000 microwatts idle and dark). This is a 30 times efficiency gain. This insane efficiency in turn allows modern solar quartz to deliver an energy surplus of about...
The advantage is, I send out most articles as free. The full article is therefore always in your email. Then a week or so later I may turn the same article to paid.
