Though one or two say that plants may produce energy from the sun, which we all know, can that energy be used for electricity? Also, even if it may, is it efficient? I will be researching into this more, and tell you all later!

Supporting: Can Plants be used as EFFICIENT Solar Panels? Michael's Project Q&A #1 Yes/No?
| Is the topic interesting enough to read about, then work on for the next couple months? | (Yes)/ No | ||
| Can you find at least 3 sources of written information on the subject? | (Yes)/ No | ||
Can you measure changes to the important
factors (variables) using a number that represents a quantity such as a
count, percentage, length, width, weight, voltage, velocity, energy,
time, etc.?
Or, just as good, are you measuring a factor (variable) that is simply present or not present? For example,
|
(Yes)/ No | ||
| Can you design a "fair test" to answer your question? In other words, can you change only one factor (variable) at a time, and control other factors that might influence your experiment, so that they do not interfere? | Yes/ No (Not sure Yet?) | ||
| Is your experiment safe to perform? | (Yes)/ No | ||
| Do you have all the materials and equipment you need for your science fair project, or will you be able to obtain them quickly and at a very low cost? | (Yes, I will be able to obtain them fast.)/ No | ||
| Do you have enough time to do your experiment more than once before the science fair? | Yes (Probably)/ No | ||
| Does your science fair project meet all the rules and requirements for your science fair? | Yes(Yay~)/ No | ||
| Have you checked to see if your science fair project will require SRC (Scientific Review Committee) approval? | (Yes, and as I'd be working with plants, it won't) / No | ||
| Have you avoided the bad science fair project topic areas listed in the table above? | (Yes!) / No |

Final Question. Can plants be used to generate solar power (in regions such as Arizona that gets a ton of Sunlight)? AKA Solar panel plants.
My final question has become this, after a bit of research. Can plants be used as efficient solar panel type objects? Recently, people have been saying plants may become the next solar panel. Trying to win in a "race", I wish to test this before them, and I wish to see if "solar plants" are efficient. It will most likely be a lot more efficient than normal solar panels, or just plants, as these will both produce oxygen, electricity, and/or electricity. I will research more into this soon, as this is a very interesting topic to me.
My questions 1-3 (before my final choice)
1. Is it better and/or healthier to live on Mars?
2. Are sun orbs more efficient in the sunlight or moonlight?
3. What causes allergies while moving from one state/country to another?
I have abandoned these questions. The reasons why are I saw the flaws within them. It is impossible to breathe on Mars, and a lot hotter there, unless using items such as artificial oxygen, etc. If we do not have those, it is nearly impossible to survive there. For sun orbs, even though they can generate power from moonlight almost just as efficiently, they get more sunlight from the sun, not the moon. Last, allergies are usually caused by climate changes.

SCE4 Summary (I meant 3 in the last post for the one I was ill during.)
Again, I have had slight problems with voki, though I will attempt to get it as soon as possible.
Scientists have recently observed that around only 1 percent of gasses going into a black hole have reached its event horizon. The rest may brighten, and is instead ejected from the black hole, with possible x-ray commissions. These results were from one of the longest observation campaigns performed in that area, and most gas that left were hotter than the sun. "We think most large galaxies have a supermassive black hole at their center, but they are too far away for us to study how matter flows near it," said Q. Daniel Wang of the University of Massachusetts in Amherst. X-ray data show the gas near the black hole likely originates from winds produced by a disk-shaped distribution of young massive stars, unlike what they had assumed. Because of going in the event horizon makes these lose heat, ejection is necessary for this to happen. The event horizon of Sgr A* casts a shadow against the glowing matter surrounding the black hole. This research could aid efforts using radio telescopes to observe and understand the shadow.

SCE4 Highlighted (Still working on 2 as was ill.)
Aug. 29, 2013 — Astronomers using NASA's Chandra X-ray Observatory have taken a major step in explaining why material around the giant black hole at the center of the Milky Way Galaxy is extraordinarily faint in X-rays. This discovery holds important implications for understanding black holes.
New Chandra images of Sagittarius A* (Sgr A*), which is located about 26,000 light-years from Earth, indicate that less than 1 percent of the gas initially within Sgr A*'s gravitational grasp ever reaches the point of no return, also called the event horizon. Instead, much of the gas is ejected before it gets near the event horizon and has a chance to brighten, leading to feeble X-ray emissions.
These new findings are the result of one of the longest observation campaigns ever performed with Chandra. The spacecraft collected five weeks' worth of data on Sgr A* in 2012. The researchers used this observation period to capture unusually detailed and sensitive X-ray images and energy signatures of super-heated gas swirling around Sgr A*, whose mass is about 4 million times that of the sun.
"We think most large galaxies have a supermassive black hole at their center, but they are too far away for us to study how matter flows near it," said Q. Daniel Wang of the University of Massachusetts in Amherst, who led of a study published Thursday in the journal Science. "Sgr A* is one of very few black holes close enough for us to actually witness this process."
The researchers found that the Chandra data from Sgr A* did not support theoretical models in which the X-rays are emitted from a concentration of smaller stars around the black hole. Instead, the X-ray data show the gas near the black hole likely originates from winds produced by a disk-shaped distribution of young massive stars.
"This new Chandra image is one of the coolest I've ever seen," said co-author Sera Markoff of the University of Amsterdam in the Netherlands. "We're watching Sgr A* capture hot gas ejected by nearby stars, and funnel it in towards its event horizon."
To plunge over the event horizon, material captured by a black hole must lose heat and momentum. The ejection of matter allows this to occur.
"Most of the gas must be thrown out so that a small amount can reach the black hole," said Feng Yuan of Shanghai Astronomical Observatory in China, the study's co-author. "Contrary to what some people think, black holes do not actually devour everything that's pulled towards them. Sgr A* is apparently finding much of its food hard to swallow."
The gas available to Sgr A* is very diffuse and super-hot, so it is hard for the black hole to capture and swallow it. The gluttonous black holes that power quasars and produce huge amounts of radiation have gas reservoirs much cooler and denser than that of Sgr A*.
The event horizon of Sgr A* casts a shadow against the glowing matter surrounding the black hole. This research could aid efforts using radio telescopes to observe and understand the shadow. It also will be useful for understanding the effect orbiting stars and gas clouds may have on matter flowing toward and away from the black hole.
