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.
The Surface Hub is a wall or roller stand mounted device with either an 84 inches (210 cm) 120 Hz 4K or a 55 inches (140 cm) 1080p touchscreen with multi-touch and multi-pen capabilities and runs the Windows 10 operating system.
