An eye in the sky that can help catch wildlife poachers

Ol Pejeta Conservancy is a Kenyan 90,000-acre reserve that specializes in protecting white and black rhinos, has teamed up with San Francisco-based tech company Airware. This company develops drone autopilot systems. Rangers at the base can operate the drone from two laptops, one showing a map tracking the flight path, the other showing the UAV's point of view through a camera.
Thermal imaging cameras meant the drone could also fly at night, with the operators clearly differentiating the shapes of animals. They could even see how the elephants' trunks changed temperature as they sucked up water from a trough. With a wingspan of less than a metre, the catapult-launched drone flew at an altitude of about 500 feet. you can barely see it. It doesn't bother the wildlife or the tourists. Killing elephants for their tusks and rhinos for their horns has become an illicit multi-million dollar business, with demand particularly high in Asia and the trade is threatening Africa's lucrative wildlife tourism industry. Even though this seems like a good and effective idea, developing an airframe that is both light and strong enough to withstand Africa's rugged landscapes is still a challenge, especially when cost will be an issue for many game reserves. The  airware estimates that drones for anti-poaching will ultimately cost $50,000-$70,000. I believe that this idea is a very good one. It seems challenging but maybe soon in maybe about a decade this can be a lucrative business as well as a savior to Africa's wildlife.
