Comment Noon is not the middle of the 'human' day (Score 1) 282

If we want to optimize to have the most hours of sunshine : assuming 16 hours awake, 8 hours asleep, and noon is the middle of your day. This would mean that you get up at 4 AM and go to sleep at 8 PM.

Ask yourself : when do you usually get up and when do you go to sleep. Align the sunlight with that. Let's say wake up at 6 AM and go to sleep at 10 PM. Then the sun should be at its highest point at 2 PM.

About getting enough light in the morning... there are inventions for that.
Also, you're all sleeping with your windows or curtains shut, so you don't get any of the early morning light anyway.
And lots of people work in an environment without any direct sunlight.

About the children getting to school... if you arrange it so that they have more light in the morning, they'll have more days when they return home in the dark. And there are also after-school activities that they will go to in the dark. So you have to make traffic safe in the dark anyway.

Comment Typical component obsolescense case ? (Score 2) 147

It's not always possible to get the electronic or electromechanical components for designs that are 10 yrs old. Especially in niche designs, where special components are needed for which there is only 1 manufacturer. Also, it may be possible to get a component from the manufacturer, but only if you buy 10000 pieces. Also, 10 years IS a long time for an electronics design. How many devices do you use at home which are that old ? For consumer products like TVs, or industrial products, manufacturers have experience with several generations of such product to improve it. Not so for innovative or experimental products.

Quote from the live video: "And then I see the disinfectant, where it knocks it out in one minute. And is there a way we can do something like that, by injection inside or almost a cleaning, because you see it gets in the lungs and it does a tremendous number on the lungs, so it’d be interesting to check that, so that you’re going to have to use medical doctors with, but it sounds interesting to me. So, we’ll see, but the whole concept of the light, the way it kills it in one minute. That’s pretty powerful."

Is it a question or a suggestion ?

At least it is suggestive.

Radiation intensity lowers by the inverse square of the distance to the source.

So if you have a radio source, and measure 1W at 1m distance, then you'll only measure 1/4W at 2m, 1/9W at 3m etc...

Works for non-metric units as wel, but then it's called the upturned quadrangle law or something...

And yes, Watt may not be an appropriate unit here, but depends on what you measure (e.g. heat absorption in your head, then it could be appropriate).
