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.
The Surface Hub is available in two sizes. The first measures 55 inches and is designed for huddle spaces, smaller conference rooms, and offices. Its cost is set at $6,999 (USD). For larger meeting spaces, there's an 84-inch model that costs $19,999. These prices are not unreasonable when compared to what Polycom and other companies charge for their conference room solutions.
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.
