Sprinkling smart dust in bird feed to simulate a UAV attack on radar. You may significantly compress the pad of your back seat. This would even make an excellent UAV for military patrols.
The modern battlespace is changing in the actual world and in the very near future swarms of UAVs with be a tactic and weapon of choice. Is your computer game software ahead or behind the curve of inovation. How will these UAV swarms be launched, what speeds with they travel? How will they render the enemy useless? How will you defend against them? This is something that is keeping Pentagon war planners up late at night. This is one big issue which will determine the outcome of battles in the future.
Steam Driven Aircraft? Well I know that NASA and the USAF Research Lab was building a nuclear aircraft so it could fly unlimited time periods without fuel, so I imagine that the nuclear power would have generated steam to propel the airplane, that would have been from the 1960s or early 1970s.
The technology advances on batteries because of the funding of computer tech businesses have benefited the possibilities of UAV electric re-usable, rechargeable and re-coverable craft.
There is another very important reason why we want to fly higher than we absolutely have UAS to. Flying over one spot, we are likely to be in darkness about half of the time. Solar cells don't work in the dark. Maintaining the same altitude for 12 hours would need a massive number of rechargeable batteries. To save on battery weight, we are going to slowly lose altitude at night. We still need to avoid the airliners and the weather, but now our UAV glider will be more effective.
This is the most used perk for beginners. It gives your weapon additional damage against enemies. This is wonderful for a beginner desperately trying to make a kill. You will more likely be using this perk at the start for a little while.
What I would recommend you is to sticking with a few firearms - where you will need to learn - a close-ranged gun such as a sub-machine gun or a shotgun and the other one is long-ranged weapon. You may use short-ranged weapons in small maps surrounded Commercial drones with buildings and you can use long-range weapons on bigger maps.
Unlike wasps or bumble bees, they need to work all year round Sunset in the North Sea taken with MA2 order to survive. They work hard when there is nectar and pollen and feed this surplus in the winter when there are no flowers. This is where beekeeping comes into its own.
If we wanted to fly a UAV over North Korea, Iran, or Venezuela we can only receive a very small and lightweight UAV made of those materials and it may fly around and take pictures forever. Best of all it could be made translucent, with a stealthy body creating a very low radar signature. It is my contention that this concept is 100% workable today with current materials, and it's too bad we have not started already and financed such a great project. Indeed I hope you will please consider all this.
