product highlights
PASSIVE direct air capture WITH EMBEDDED SOLAR CSP “SOSNAPOD”
CO2 is converted into fuel as efficiently and effectively as in natural photosynthesis. The portable pod can be used to mine carbon from atmospheric dioxide anywhere, with or without solar energy. The machine generates heat, cold, electricity and water.
Clean high-efficiency Internal Combustion Engine + Custom
The high-power clean engine runs on any fuel: gaseous, liquid and solid. The efficiency factor of this engine is twice as high as the efficiency of modern engines, which makes it more environmentally friendly than electric vehicles. Custom design is available to meet specific industry requirements.
single-stage-to-orbit aircraft "octopus"
The aircraft will pass the entire corridor of speeds and altitudes of horizontal flight to low orbit around the Earth. We've developed this technology for vacuuming the air intake of an aircraft at hypersonic flight speeds, which dampens the shock wave, reduces drag and increases speed.

This SosnaPod uses a novel method of thermodynamic CDR via freezing with a high degree of conversion of solar energy into electrical energy. Built-in precipitation-resistant solar concentrator inhibits accumulation of obstruction materials such as dirt particles and debris (dust, water, sand, moss, grime), preventing loss in power output. Degradation-resistant design delivers a consistently high yield year-over-year. This cryogenic method of DAC would capture between 75%-90% of CO2 from air. The amount of water released depends on air humidity. The unit could deliver 400x more water than CO2 if the atmosphere has 10% humidity and 0.025% of CO2. This DAC method avoids biggest environmental impacts associated with DAC adsorbents footprint (4.8–84%) and energy footprint (0–92%). It sidesteps some of the development, permitting and capital challenges associated with building large facilities. Its design and manufacturing rely on already existing materials and supply chains preventing complex redundancies, minimizing uncertainties and delays.
The kinematic design of the machine allows you to set any compression level even during operation. Various grades of CO2 purity may be achieved.
Compatible with existing energy storage systems. Preserves the curb appeal and historic sites. Perfect for difficult terrain.
One pod occupies 3X less space than PV modules, saving at least 13 sq. meters needed for panels to achieve equal power.
Works in any temperature existing in nature. Ideal for cold climates (cold climates are thermodynamically more favorable for CO2 separations).

DIRECT AIR capture
method I: tandem - high output
DIRECT AIR Capture + embedded Solar CSP
(GENERATES electricity, cold, heat, water)
The pod captures carbon dioxide directly from ambient air via a thermodynamic process. It operates on low-grade heat of the surrounding space. The physical properties of carbon dioxide are significantly different from the rest of the components in the air. At a temperature of 200K and low pressure, when oxygen and nitrogen are stable gases, carbon dioxide becomes liquid, or takes on the form of flakes. These fractions can be successfully separated from the gas.
The essence of the calculation process is as follows: a portion of air is sucked into the working chamber, compressed, fed into the heat exchanger, cooled, fed into another, large, working chamber, expanded and supercooled to the conditions where carbon dioxide changes its state of aggregation, and passing through a cyclone and separator, separated from the rest of the gases.
Along the way, atmospheric moisture develops, becoming frost. Air, now without carbon dioxide in it, remains cold enough to be used for air conditioning.
The air is compressed and fed into a high-temperature cavity installed at the focal point of the solar collector. From this hot cavity, heated air with high pressure is fed into the working chamber of the external circuit. There the air expands and performs its work by causing the compressor shaft and shaft-mounted electric generator to rotate.
method II: solo - low output
DIRECT AIR Capture
(GENERATES electricity, cold, heat, water)
The pod can work without solar energy, operating only on the heat of the pumped air. This method generates lower output. It's ideal for a wide range of household applications. For this reason, the unit is made with appropriate configurations tailored for direct-to-consumer domestic needs.
It will deliver heat for heating the home and cooking, water for drinking and washing, electrical energy for lighting and powering low-power appliances. In hot weather it will cool the room, creating comfortable conditions.

hermetically airtight chambers
Hermetic tightness within the working chambers is achieved with labyrinth seals. Complete tightness despite the fact that the movable volume-forming elements of the working chambers do not touch each other, do not require lubrication, do not pollute the pumped product, no energy is wasted on friction, as there is no mechanical friction.

According to the theory, “... in the case where the pressure in the sealed cavity cyclically fluctuates from a maximum to zero, a wave of gas rushing into the seal has a limited energy reserve, which can be completely dispersed in the seal. Under these conditions, labyrinth seals can provide practically complete tightness." - P. I. Orlov, “Fundamentals of Machine Design”, Ed. Engineering, 1988, p. 493.
“Labyrinth seals have a long history of proven reliability in a wide range of applications, including bearing chambers, see Fig. 14.24, in gas turbine engines as well as discs and stator wells (see Chupp et al., 2006a,b), with robust operation and developed technology.” Peter R.N. Childs, Mechanical Design Engineering Handbook (Second Edition), 2019
motor-compressor
runs the pod
At present, the best version of the motor-compressor can be made according to the kinematic scheme of the rotary engine of the internal combustion (patent UA57724).
The absence of mechanical friction losses ensures a stable operation of the machine and compensates for reduced solar energy in cloudy or partly cloudy weather.
The motor-compressor has:
