I was recently contacted by "Renewable Energy Global Innovations" about a paper that I got published in the beginning of this year.
In the email, it was stated that they consider the paper to be relevant and they would like to have it mentioned in their magazine, something which would provide me with visibility to both the academy and industry. All this at the moderate cost of 35$ (quite little, indeed).
My question is: has any of you had any experience with this service? Is it something serious or just a way to take easy (small) money from inexperienced researchers? Should I consider this like an "honour", or it is actually not?
A brief research online did not end up with any evidence in either direction. A few researchers were claiming proudly that their work has been selected for this collection of papers, but not many. On the other side, no headline "REGI is a scandal" either..
Comments will be really appreciated!
