  • I think it’s best to get out of that cycle and force your body to wake up at the first alarm. Otherwise you’re just wasting time on nothing - your brain doesn’t rest properly in those 5-minute doses and you’re not getting ready either. The way I’m doing it is to put my phone in a different room next to my bedroom so that I have to get out of bed to turn off the alarm. If you’re managing to sleep through alarms it’s probably not the solution for you, so maybe the QRAlarm recommendation made elsewhere in the thread is better.


  • The article is very light on details, but the numbers don’t seem to check out at all. Back-of-the napkin math (assuming a square 1km × 1km solar array and total sun luminosity of 3.83e26 W):

    1 km ^ 2 * (3.83e26 W) / (4 * π * (1 AU) ^ 2) * 1 year to TWh ≈ 11.94 TW·h
    

    This is a “measly” 12 TWh of TOTAL energy delivered to the array over a year - not accounting for solar panel efficiency losses (20-24%) or the elephant in the room of transmitting this energy back to earth. For context, China alone consumed around 39 PWh (39000 TWh) of energy from fossil fuels just over the course of one year, 2023. The entire world consumed 55 PWh (55000 TWh) of oil energy in 2023 alone. It’s not even comparable to the annual consumption of oil. If we consider the aforementioned factors, assuming 24% solar panel efficiency and an extremely generous 50% power transmission efficiency, we get:

    1 km ^ 2 * (3.83e26 W) / (4 * π * (1 AU) ^ 2) * 24% * 50% ≈ 163.43 MW
    

    Which is literally nothing on a national scale - it’s less than a percent of the Three Gorges Dam output.
