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.
A new Surface Pro with an Intel Core i5 processor, 8GB RAM, and 256GB of storage will cost you $1,300. It sounds mighty tempting when you compare it to Apple's equivalent MacBook Pro, which costs $1,500. But once you add the $130 keyboard for the Surface Pro, the total cost racks up to $1,430, which is only $70 cheaper than the equivalent MacBook Pro. And it might seem like Microsoft's most powerful Surface Pro offering, which includes a Core i7, 16GB RAM, 512GB of storage and cost $2,200, is a much better deal than Apple's equivalent MacBook Pro with similar specs, which costs $2,500.
