Up front capital invested can range from as low as $500 for a small, shallow pond aeration system to as much as $8,000 or more for a larger system or a solar aerator.Operating cost is dependent on the number of amps needed to power an electric motor multiplied by the electricity cost in your area.ome electric aerators might run for 2-3 years without any major issues and others might run 5-7 years or longer. The table below is based on a set of assumptions that is fairly representative of actual costs for a 1 to 2 acre pond or small lake.
Surface Hub costs less than half that, and is in essence a collaborative center in a box. Costs for a conference room that would accommodate the lower-end unit are about $6,500 to $27,000, again not including furniture, installation, service, and ongoing management costs, so a similar savings can be had there as well.
The Surface Hub requires a few different credentials depending on what you want to do with it. To access the Settings app, you have to sign in with the main administrator account. To get the Surface Hub's communication apps (aka Skype and email) working, we had to sign into an Office 365 for Business account.
