A totally new design concept has been applied to the "good old" steam engine that allows this previously very reliable but relatively inefficient machine to drive an electric generator to make enough power to provide the thermal input needed to drive the engine AND have a substantial amount of power left that can be used to power any number of devices.
A system that would be small enough to fit in the basement of a 120 square meter residential home could provide enough electric power and thermal energy to support everything within a 20 km radius of the ...

URBAN-REGIONAL TURBINE BLADE
Several prototypes have been built in various stages, to increase the aesthetic appeal of our blades to insure their durability and its sensitivity to wind conditions and to our community’s growing need for a more efficient and economical wind turbine blade.
The blades can be manufactured out of different materials to suit industries, e.g. smaller blades can be of injected mouldings, pressed metal or even recyclable materials. Larger blades can be of pressed metal and can be assembled in parts. Much larger blades can be of reinforced composite materials.

Vertical Axis Windmill
Vertical axis windmill with a unique design and a unique control mechanism
This design is very scalable from medium to large sizes. It has low maintenance costs because it can be serviced from the ground. Doesn't require a complex or hi maintenance braking system. Can be converted from drag to lift air foil designs. Low rotational speeds are less stressful on equipment and doesn't require hi tech or hi strength materials. It is self starting unlike other designs.
Low rotational speeds and rotor angle make it visible to birds to minimize bird strikes. Works in low wind ...

Even in the desert where the air seems to be completely dry, there is moisture.
Having moisture in the air does not mean rain. Moisture in the air to turn into rain in this cloud and many factors are needed.
How can we take advantage of this water in the air before the rain?
The proposed project intends to extract water particles from the air, even before the rain happens.
Parts of the project are:
a) a metal tube (about 100m),
b) a collector of water on top,
c) water gutters connected to the collector with ionized ...

Supplementary and retrofittable wind turbine expansion with vertical rotors in connection to existing or new wind turbines.
(Dipl.?Ing. Derik Tesche / firstname.lastname@example.org)
This development refers to the tower of a wind turbine at its Installed outside wall vertical rotors are, in addition, the main rotor to generate power (See sketch).
- low start-up speed of 2-3 m / s wind speed
- available from energy outgoing lines and facilities
- to exploit the existing geometrical height up to 150 m / 450 feed high masts for higher and consistent wind speeds ties
- improve ...

Do you believe in the ability of a wind-electric turbine to generate electricity? How about the functionality of a hydroelectric dam to do the same power generation? Both the wind-electric turbine and the hydroelectric dam capture the motion of some other element/fluid (wind in the case of the wind turbine and water with the dam). Motion means kinetic energy is present. Both the wind-electric turbine and the hydroelectric dam convert the fluid motion of their targets (again, wind and water, respectively) into electricity. The more wind that blows, the more electricity the wind turbine can produce. The more water ...

The idea visualizes the solutions for the futuristic green buildings. The implementation of techno-green management and architecture in construction will lead to sustainable green homes. In India, buildings account for 30-40 percent of energy use, known to be energy guzzlers. The current conventional residential structures pose impending threat to our mother nature. The idea of green building promotes use of renewable energy, reused and recyclable products, focus on efficient use of water by rain water harvesting program envelope and grey water treatment, improving occupational health and comfort through HVAC systems.
Green Buildings have major potential areas to be tapped ...
