Tangential flow
Directing the air flow toward the generator blades along a tangential line to the rotation circle optimises the generating module’s torque.

ENERGY IN MOTION
Flow becomes reliable power
X-Energy guides and concentrates the air flow, transfers rotation to the generator and delivers electricity to the consumer — from a local facility to the wider energy system.

01 · ENGINEERED SYSTEM
Technology and innovation
Four engineering principles make the system compact, modular and efficient.
Less material
Lower material intensity than conventional wind installations, combined with a higher specific power output.
Modular capacity
Several modules can be installed together to use wind speed efficiently and scale the output. Up to five modules can be stacked vertically.
Quieter and more efficient
Shielding inactive blades from the incoming air flow improves efficiency and reduces noise to a normal level.
02 · OPERATING PRINCIPLE
Flow concentration amplifies its power
from 3m/s · stable operation
up to 50m/s · load regulation
60m/s · stop gates engage
The unique multi-stage air-flow guidance system not only raises X-Energy efficiency but also solves operating-noise problems. The installation can therefore be placed close to residential buildings. Combined with V. V. Shkondin’s generator, X-Energy is more than three times as efficient as other wind generators.

03 · REAL-WORLD REFERENCES
Compared with real projects
The new wind-power solution can cover a building’s own demand and also supply energy to external consumers.
Bahrain World Trade Center
3% self-sufficiency7–12 m/s wind speed
The Bahrain World Trade Center is a 240-metre twin-tower complex in Manama, Bahrain. Completed in 2008 by Atkins, it incorporates sky bridges with wind turbines.
Pearl River Tower
10% self-sufficiency7–12 m/s wind speed
This supertall skyscraper stands in Guangzhou’s business district and was completed in 2013 in a neo-futurist style. Its wind turbines and solar panels were designed to cover the building’s own energy demand.
X-Energy
124% self-sufficiency3–50 m/s wind speed
This output is achieved through the wheel-generator technology on buildings of different heights and designs. A building does not need to be the tallest or largest: most structures can accommodate X-Energy. Multi-stage wind guidance gathers and concentrates the air flow in the blades.
04 · SHKONDIN GENERATOR
Improving existing energy generators
V. V. Shkondin’s generator technology can create a new ultra-efficient source of energy and substantially improve existing generating systems.
01
Hydroelectric power plants
81% today→up to 900% with the Shkondin generator
Hydroelectric efficiency is calculated as efficiency = Eout × 100% / Ein, where Eout is the energy generated by the plant and Ein is the energy of the falling water.
Details and calculation
Generated energy: Eout = Pout × t, where Pout is the plant’s output and t is the generation period.
Energy of falling water: Ep = m × g × h; m = V × ρ; therefore Ep = V × ρ × g × h.
Efficiency = Pout × t × 100% / (V × ρ × g × h).
Efficiency = 73 × 10⁶ W × 60 s × 100% / (15,000 m³ × 1,000 kg/m³ × 10 m/s² × 36 m) = 81%.
At these parameters, the Shkondin generator can significantly improve the result and produce up to 900%.
02
Water locks
0% today→up to 200% with the Shkondin generator
Low water velocity and numerous passage locks make a conventional hydroelectric plant economically inefficient.
Details and calculation
The Shkondin generator technology consists of only five elements and starts producing a stable electricity flow from water moving at two metres per second.
This makes it possible to achieve exceptionally high efficiency and power nearby facilities or even communities.
03
Thermal power plants
60% today→up to 300% with the Shkondin generator
Thermal power plant efficiency rarely exceeds 48%. Common steam plants use fuel oil at 36% efficiency, coal at 47%, or natural gas. Combined-cycle plants reaching 60% are the most efficient.
Details and calculation
Building such a plant costs more than €80 million, while the payback period can stretch across decades.
The technology can significantly raise performance to 95% and at least halve the payback period through higher productivity and lower production costs.
04
Propeller wind turbines
25% today→95% with the Shkondin generator
Average wind-turbine efficiency is about 25%. Their specific performance metric is the wind energy utilisation coefficient, which has increased from 10–15% for historic windmills to 35–40%.
Details and calculation
A calculation based on total electricity output gives a relatively low overall efficiency of about 20–30%.
Propeller turbines remain popular because they are inexpensive to build. The new technology can multiply their performance, add practical advantages and deliver almost four times the efficiency.
