Why Waste Mangement???Diesel
3 miles / gallon.22.2 pounds CO2 / gallon.About 40 known and suspected carcinogens.Health issues...higher prevalence of Lung Cancer.

Lower Hardware CostsLower Learning Curve for DevelopersDelegation of Network Capabilities to End UserMultiple Kinds Of Sensors (T/P/Gas etc.)Can Be Placed On Data Gathering Platforms (Cars?)
Benefits of Approach
Samrat Saha
Must have End User Buy In - ● Download!● Low impact on regular schedule
Must have High User TrafficNot Suitable For Real Time -
● Needs modifications for always on
Drawbacks of Approach
