For comparison, what a "good" i.e. well researched "Would X work?" reactor question might look like:
Example 1 (as originally posted):
The question What is the best Lagrange point for beamed power supply to spacecraft? reads in its entirety:
If a small reactor could be transported or assembled in space or solar cells, which Lagrange point would be the best for the reactor to be to beam energy in some form to a spacecraft to increase the out put of an ion or magnetoplasmadynamic thruster?
-1and vote to close for unclear. This is another mashup of a nuclear reactor, solar cells, energy beams, spacecraft, magnetoplasmadynamic thruster, Lagrange points and orbital mechanics, all in two sentences including the title.
The question Steam Engine in Space this way? reads in its entirety:
Could 2 tanks be designed to rotate slowly in space creating gravity in the tanks. The tank facing the sun would boil the water to the other condensing tank to cause the water to move a turbine similar to the sand moving past the neck of an hour glass?
Both tanks condense and boil depending on the orientation to the Sun.
Voted to close and my three comments there:
This is question asking for someone to help you invent a steam engine and doesn't really have anything directly to do with Space Exploration. You can propose your design in Engineering SE butI think it's really off-topic here. You have sunlight, shadow, and vacuum, and those can be addressed there without problem.
I'm voting to close this question as off-topic because it's asking for help to solve an engineering problem about a steam engine. That it happens to be in orbit doesn't really make it on-topic here. In fact, I'm beginning to wonder if "Please invent my invention for me" questions as a class are becoming problematic.
One reason I feel that these very short "Could this idea work?" questions are problematic is that they require other people to develop an embodiment of your invention for you, then to do an engineering evaluation of their particular embodiment, then write an answer based on that. It requires other people to basically write your question for you. A better way to ask your question would be for you to do some of the work yourself and write it up, then ask a question referring to your embodiment.
Question: How do other people feel about this kind of question? I've seen other questions recently, some as short as two sentences including the title, that are also "Please invent my invention" or "Would X work?" questions, so is this the new norm, or is it better to try to get some personal, prior research into almost all of ones questions?
