Sun Calculator

I think you are right....I might borrow one but not invest in one...

Well, for me it is a waste of money since i wouldn't be using this stuff for any reason in my life. If it's invented, there are certain people that are using it to accurately measures those things. But things like this that we thought has no use is really has no use at all. I can tell you that most of these things that has no use or practical use at all is invented in Japan. Honestly, sometimes those things that were invented in Japan but has no practical use is actually look cool and awesome, of course not all of it but still a waste of cash if you ask me.

Couldn't you see if the sun was shining on a certain area? Just wondering... If it wasn't expensive, I can see using it to be sure of getting enough sun for, say, tomatoes or other garden vegetables, or for placing a solar oven when you won't be home to move it around when it's needed. If it costs very much, I don't think it would be worth it.

Do you mean a calculator that runs on Solar Power energy. Well, I have had calculators like that, and let me tell you that I only use them for back up. That means that if my main calculator is broken, then I will use the solar powered calculator as a back up. I honestly don't recommend those kinds of calculators because you have to have them in sunlight or in lamp light in order for them to work, and if you don't have a lot of light around you, then they won't work.

It sounds like it is a monitoring device to track the activity of the sun in your area. Maybe it is usable in your garden if your plants need a shade from the heat of the sun. If it is too much expensive why give it a try.

With something like this I'd just check different parts of the day to see. I know there are some plants that need a little shade while some need full sun etc. I'd just go outside several times a day to check what the ground looks like proportinate (I butchered that spelling pretty bad) to the sun.
