Water supply of deep space missions

The continuous supply of water is an essential factor of space missions since water is consumed by astronauts and they use it for other purposes too. These can be for example growing plants in the space and protection against cosmic radiation. Water can be demolished into oxygen and hydrogen by electrolysis to provide the continuous oxygen supply of the astronauts while hydrogen can be used as refrigerant, for energy production in fuel cells or in ion engines as fuel. Furthermore, burned with oxygen, hydrogen can provide powerful thrust in rocket engines as well.

However, water supply to space missions as a payload mass of current carrier rocket is too expensive for the universal use of water in a large quantity. Because of this, a C-5M Super Galaxy transport aircraft should be transformed in a research and development program so that a railgun would be installed into the aircraft with the supercapacitors providing power for firing.

Charging the supercapacitors would be provided by s…

Made in Tibet

Increasing the living standard of the population of Tibet is not only about eliminating poverty, since the economic power of the Tibetan people fundamentally determines their ability to enforce their interests from freedom through environment protection to autonomy.

However, the Tibetan development program of China is primarily about the extension of Chinese interests and about validating them at whatever cost, from education through transport to mining, therefore, with the Chinese economic development programs, the Tibetan people actually do not move forward at all.

In my opinion, because of this, the Central Tibetan Administration should start an economic development program, which would be explicitly about mitigating poverty in Tibet and about strengthening the ability of Tibet to enforce its interests.

Within the frames of this economic development program, the Central Tibetan Administration would appoint those Tibetan companies, which would really improve the Tibetan economy by …

Deployable observer and radio transmission drone

Nowadays, warfare is based on communication capabilities that make the use of specialized ability units possible in coordinated ways, and among other things, gathering information for decision making. So, the drones with observational and communication capabilities has become a significant part of modern warfare.

This type of drone would basically be a remote-controlled electric helicopter, which could be launched from below an aircraft wing, thanks to its foldable structure, for example using the universal underwing pylon of the C-130 Hercules.

This kind of drone would work on the ground, the helicopter mode should only be for deploying.

Simplified structural diagram:

1. The body of the drone would consist of two main parts, this lower part would contain the batteries. Thus the drone’s center of gravity will be low, what is important for its stability.
2. The upper main part of the body would include the communication and control subunits, the radios, the GPS receiver, the flight con…


There are tens of thousands of indoor and outdoor shooting ranges in the world, where shooting is practiced on a wide range of targets, but I think it would be worth using smart targets to expand the training possibilities further.

The Gunslingers would be a separate app that anyone could install on a smartphone. The app could connect to this smart target, making it possible to play game in an Old West gunfight. The player must defeat ten gunslingers in the game, who would become more and more difficult opponents.

Simplified structural diagram of the smart target:

1. The structure of the smart target can be different sizes, but the most common size would be the human size. The frame of the smart target would not be bulletproof, because the players can only use rubber bullets.

2. Two pairs of light curtain sensors would be integrated into the frame, which sensitivity would be adjusted to the size of the projectiles. One of the sensor pairs would be vertically embedded, so when a projec…

Firefighting airship

At residential areas without an unlimited supply of water to extinguish fire, or at unoccupied areas without proper infrastructure, extinguishing extensive bush and forest fire is often an unsolvable task, because the opportunities of the delivery of the extinguishing material to the target location are always limited, independently of the number of the available tanker trucks or firefighting aircrafts.

The modern version of the legendary, ocean liner-sized Graf Zeppelin filled with helium instead of hydrogen would also be capable of transporting extinguishing material, because its payload capacity similar to firefighting aircrafts. However, because of its significantly lower airspeed, it would be able to carry out turns too slowly.

Nevertheless, the airships’ ability of hovering at one place makes the on-the-spot creation of the extinguishing material possible instead of transporting those to the fires.

This new type of firefighting airship, which could have the length of three hundred…

PCI card to Nokia smartphones

In my opinion, it can be calmly stated that those part of the Earth’s population, which has the sufficient funds and the demand for the usage, has already purchased some kind of a smartphone. Because of this, when consumers change their smartphones, companies like HMD Global can only increase their own market share against the other manufacturers.

And since consumers encounter a great variety of offers regardless of their financial possibilities when they change their old smartphones, so for hardware manufacturers like HMD Global marking out from the mass is incredibly difficult. In addition, without an Apple-like own software environment and cloud services, keeping the extant consumers through brand loyalty is also nearly impossible.

Nevertheless, the brand loyalty can be increased, if HMD Global produces multipurpose smartphones, because after getting rid of these smartphones, the post-change fate of those can also get into the decision-making process of the consumers.

The PCI card:
