I thought this may have been NIROSETI but it isn't I wonder how NIROSETI is doing they search by looking at near infrared signals.
Here is what they do:
>Near-infrared Optical SETI (NIROSETI) has the advantage that light at infrared wavelengths is less affected by interstellar gas and dust; an infrared signal can be seen at greater distances than an optical signal at shorter wavelengths. Also, it takes less energy to send the same amount of information with an infrared signal than at shorter, optical wavelengths.
