- eink or lcd display, for always-on and long battery life.

- brightness adjustable LED, for night usage of the watch and as flashlight at night.

- physical buttons, for controls including music volume, skip to next or previous song.

- bluetooth calls and notifications.

- nfc payments.

- functionality allowing to COMPLETELY DISABLE all those fitness functions, such as step counting or heart rate measuring. FU Garmin, I hate you.

- app for plotting tides and moon phases.

- app for voice memos, then transfer to Android/iOS for converting voice-to-text and further editing.

- if the display is touch-enabled, make sure to make it LOCKABLE, otherwise it does self-activates in the shower if the message is received. FU Amazfit, I hate u2.

- solar panel on the sides or even maybe behind eink/lcd display.

At the moment I am using Tissot T-Touch Solar Connect: No nfc payments, no bluetooth calling, no flashlight at night, no tides/moons, no music control But, I never need to charge it!!!!! And I dont need to use my second hand to press the led button to check the time at night, because its a hybrid watch with luminescent arrows.

- Convert your personal Needs to your Wants/Wishes.

Dont know what cheap means for them, but it will never be for free because abundance happens when the supply exceeds demand and I dont see the scenario where the demand for energy is declining in a long run.

To minimize theta, we need to either increase D or decrease lamda.

Lets assume we would be able to make far infrared high power lasers, at say 10,000 nm = 1e-5 m wavelength.

Lets assume we would be able to make D, the diameter of our laser beam, similar to the diameter of a typical planet, for Earth it is ~13,000 km = 13e6 m.

Theta = 1e-5 / 3.14 / 13e6 ~= 1e-13 radians.

Sun is ~ 25,000 light years from the center of our galaxy, ~= 25e3 y 3e8 m/s 31.5e6 s/year ~= 1e20 m.

Laser beam diameter, there far away, would be: 1e-13 *1e20 = 1e7 m, similar to the diameter of Earth, not much further diverged, focused and delivering the wast amount of energy all over the planet thereby evaporating it to a gas.

Indeed, what you say about the melting far away planets is possible, in theory.

Lets assume energy converting photovoltaics will be made of non-crystalline materials with a high light absorption coefficient allowing solar cell thickness of ~100 nm = 100e-9 m.

Sphere surface is 4pir^2, in our case 43.14150e9^2 = 3e23 m2 * 100e-9 m = 3e16 m3 is the total volume occupied by a Dyson swarm tech.

For comparison the volume of matter that Earth contains is 1e21 m3, which is 1e21/3e16 ~= 1e5 = 100,000 times larger than what is required for a Dyson swarm.

My attention to those emails is 20 emails * 10 seconds/email = 200 s / 60 s/min = 3.3 minutes of my time daily * 365 days = 20 hours per year!

What are my options for charging the sender for my attention?

Are there any crypto mining schemes for this, similar to javascript mining while visiting a webpage?
