With some very simple equipment and knowledge of basic math it is possible to estimate the power output of the sun.
This video describes the process and explains the calculations. The video leaves a challenge, use the results to calculate the total energy arriving at the earth each second and using E=mc^2, calculate the mass loss of the sun.
Your equipmemt can be and should be sold for each school for a science project.
Good concept. Well done!!!
Thank you.
Very simple, elegant description!
Thanks for sharing!
What about the solar energy that is reflected off of the first surface of the glass, especially as the rounded surface will reflect more and more of the signal ( incident sunlight)
Great video, by the way!!!!
e = m c^2
m = e / c^2 >
m = 3.1*10^26 * 299,792,458
m = 3.44^12 gr/sec = 3.44 Million tonne/second
that's pretty impressive :) (the real figure is a bit over 4million tonnes according to wikipedia)
i will have to try this with
Nice... Hope it doesn't take too long for your next video(s)..
Fantastic
@neoaeonian Fossil fuels are solar energy stored in chemicals.
There's an interesting TED talk related to this. Basically, it was saying that if we were able to convert a swimming pool sized amount of water into hydrogen and oxygen every second (using the sun!) we would be able to solve the world's energy problems.
At about a tenth of a watt (0.1 W) per square centimeter it will take about 10 square centimeters to have 1 watt of energy. A square that size is about 3.16 (the square root of 10, about 3) centimeters long on each side which is about one and a quarter (1.25 in ) inches long.
great learning videos, thank you.
517,426,273,458,445,040,214,477.21179625 horse power from the sun
140,511,914,900,262,400watts=power to earth per second or
188,353,773,324,748HP or
21,617,217 barrels of oil per second
1.56 grams to the earth
4,294,829,216 grams total (this seems high to me but hey)
I love these videos.
Excellent video folks. Thanks much. :)
@Lineriderrocks123,
Nothing with mass can go faster than or equal to the speed of light. As a particle approaches light speed, it takes progressively more energy to accelerate it, and infinite energy to push it to exactly the speed of light.
E = mc^2 lets us compute how much energy an object with mass is "made out of". A small amount of matter can annhiliate to release a large amount of energy. For example, nuclear fission or fusion causes a reduction in mass and a release of energy.
Very nice, thanks.
hey loqiloqi...your statment is wrong a couple of ways..
rosenburg bridge (allowing/enabling faster then light travel in a way one need not go faster then C.. Also..many things travel faster then speed of light (unknown & un-realized to Einstein at the time)
Another tool with the same result, a must for any solar cell owners.
very nice video
Very Good Video by the way
That's a lot of energy. No wonder the sun is so hot.
very good and tutorial !
It seems a shame that all the knowledge we have about nuclear fission and fusion has mainly gone to waste due to some peoples ignorance of how dangerous this power actually is. Instead we pat ourselves on the back and build overpriced monolith like windmills and solar gardens.
Interesting.
very nice video
