The Nephilim Project

Efficient Energy Systems is a start-up in research, development and production of middle and heavy class drones.

Initially, we thought that it would be fresh to create a hybrid power plant for cargo drones - instead of batteries - because batteries are cumbersome, they have long charging times, high maintenance cost and other limitations - clearly, a hybrid power plant is the obvious alternative to batteries.
At that time, we placed all of our focus on the research and development of a hybrid power plant. Initially, our plan was to sell our product to companies that specialize in the development of drones. After some time, we realized that many companies create small drones and it would be difficult for us to sell our hybrid power plant to them, due to its size. At this point, we realized that we must begin research and development, and eventually production, on cargo drones.

Commercial drones are used primarily in the following areas: agriculture, service of huge technical objects, geodesy, video and photography. These areas account for almost 90 percent of the market for commercial drones. However, another segment of the market interested us – cargo drones, and more specifically, cargo drones for delivery. Our interest began to grow even more after being inspired by cargo drones for business giants like Amazon Prime Air, DHL, UPS and Chinese retailer,

The development of such a heavy drone is a complex task. Certain problems must be resolved, which are include the following:
- Aerodynamics of body and rotor
- Heat transfer (cooling the elements of constructions)
- Electricity (creating an interface from the hybrid power plant to other systems of the drone)
- System logic (how the drone functions without the control of the operator)
- Creating a durable and hard, but at the same time, a maximum light body for the drone

We have a great team to resolve these problems: our team consists of uniquely qualified specialists who have a great deal of experience in their respective fields. These fields include the following: aerodynamics, heat transfer, structural strength, electricity design, programming of microcontrollers and industrial design.

Project Nephilim is the fruit of our hard labor. This middle class drone has a maximum lift off mass of 25 kilograms. Its maximum payload is 10 kilograms. Such a payload has a flight time of approximately one hour. By our measures, this is an outstanding result. We believe that the world will benefit tremendously from the Nephilim.

Now that Project Nephilim is in its final stage of research, the development phase will begin. Several drone systems will be designed, followed by experimental research. Initially, the price of the Nephilim drone is estimated at $23,000. This price is comparable to other similar products on the market. In fact, some companies have a drone for the same price, but our drone has better specifications.

At first, the Nephilim drone will be sold for postal and delivery services in Australia, United Arab Emirates (UAE) and Russia.

It is our belief that once the speed of delivery is increased, the price will decrease at the same time. Thus, making the world a little better.
