The bold technology integrates three turbines in a row or series and increases the electrical power output for a single tower.
and accelerates wind before delivering it to turbines safely and efficiently located at ground level. By placing three turbines in a series in an INVELOX system,
additional 120%power may be generated compared to a single turbine. Recent reports state technologies have allowed some markets in renewable generation to be competitive with coal or natural gas.
This is good news however, renewable energies intermittency and massive size challenges will continue without industry changes.
placing turbines safely covered at ground level allowing installation close to the end user. This could be the beginning of transforming wind power into the baseload power source that coal has been since the early 1900s.
Multiple turbines in a single INVELOX tower means nearly zero operational downtime because maintenance can be done on one turbine
while the others continue producing energy. With INVELOX capacity factor at 600%and turbines installed safely and conveniently at ground level,
maintenance costs and failure is reduced greatly. See video. Benefits of multiple turbines in single tower-120%additional power output at minimum added cost of turbine-generators-Reduced capital expenditure per kilowatt-Increased production capacity
-Gain in output without increasing footprint-Offers upgradability to meet increase in power demands-Minimizes operational downtime his is a great achievement,
for the first time in wind industry history three turbines may run in series in a single tower to produce more energy.

#Altaeros Energies floating wind turbine churns out electricity and Wi-fi This floating turbine, developed by Altaeros Energies could someday travel to every remote corner of the globe.
Video) Think of these floating turbines as the wind farms of the future and you won be that far off.
The floating turbines are designed to take advantage of the powerful prevailing winds that exist 2, 000 feet above our heads.
and deployed, these floating power plants can generate twice the output of a ground-based turbine.
The tethers that keep the turbine anchored in place also send that energy ground-ward. While in the air, the turbines can also serve as Wi-fi, cell service hubs,
and weather monitoring stations. Furthermore the turbine helium-inflated housing is durable enough for deployment in either the blazing sun or freezing snow.
Basically, anywhere you install one of these suckers, you instantly get data coverage, electricity and local weather data,
such as the insides of power-station turbines, where condensation reduces efficiency. As a result, engineers are eager to get their hands on tough materials that are intrinsically hydrophobic.
As steam passes through the turbines of a thermal power station water condenses onto the blades and forms droplets many micrometres across.
The rotating blades lose energy as they smash into these droplets, accounting for up to 30%of the inefficiency of the turbine,
This means that in the United states, most towers for 2-or 3-megawatt turbines are limited to about 260 feet.
based on the force exerted on a turbine, you want something at least 20 feet in diameter at the base,

#High-flying turbine produces more power For Altaeros Energies a startup launched out of MIT the sky s the limit
Proven to produce double the energy of similarly sized tower-mounted turbines the system called Buoyant Air Turbine
Power generated by the turbine travels down one of the tethers to the ground station before being passed along to microgrids.
But despite its efficiency the BAT is designed not to replace conventional tower-mounted turbines Rein says.
Conventional turbine construction for instance requires tons of concrete and the use of cranes which can be difficult to maneuver around certain sites.
But if winds get too high above the maximum capacity of the turbine there s no reason to operate in those very strong winds
For example, the turbine blades in electric power plants become less efficient if water builds up on their surfaces. f you can make the blades stay dry longer,

and the liquid hydrogen to run a closed cycle helium turbine. The turbine powers a compressor takes the cooled air
and compresses it to rocket chamber pressure. It takes 20 kwh/kg to liquefy hydrogen.
The fully autonomous lighter-than-air BAT (short for buoyant airborne turbine) will climb as high as 2000 feet where winds blow stronger and steadier.
A The body or shroud of Altaeros's Buoyant Airborne Turbine (BAT) is kept aloft by 1000 cubic meters of helium.

A larger version will fly a 200-kilowatt turbine. The BAT can also carry radio and cellular antennae
Altaeros is also in talks with potential customers in Brazil and India where listless ground winds scuttle conventional turbines.
Whereas Makani and others aim to develop utility-scale turbines capable of powering hundreds to thousands of homes Altaeros plans to sell modest units that fill an immediate niche.
Eventually Altaeros also hopes to produce a utility-scale turbine--one tailored for offshore power.
It solves a lot of the headaches that offshore developers have today in putting these big turbines out there says Glass the company's CEO and CTO.
For now Altaeros is concentrating fully on the turbine in Somerville the one whose fin has finally finished inflating before me.

Sure, power turbines that run at a fixed speed--60 hertz, or cycles per second, in the U s.--have served the grid well to date.
There, it is mixed with water to create steam that turns energy-generating turbines. The HTF is made up of a synthetic thermal oil solution that is pumped towards a heat tank containing molten sands that can store heat energy for three hours
use it to drive turbines and then be reheated to continue the cycle. Most commonly this might be done over a 24-hr period, with variable levels of solar-powered electricity available at any time of day
That energy has been used to heat a fluid that in turn drives a turbine to produce electricity.
which would drive a turbine to produce electricity, and then residual heat could be used to make steam to drive yet another turbine.
In laboratory tests, one concern arose when the energy storage capacity of the process declined after 45 heating and cooling cycles, due to some changes in the underlying materials.
in conjunction with Oxford university researchers, believes it has devised a way to overcome this obstacle by creating a new type of horizontal axis turbine that can be used underwater at depths of up to 30 meters, at an economical cost.
Conventional propeller-type turbines are like underwater wind turbines and the number of suitable sites for them are reduced vastly by the size of their large blades,
as the water flows past the fence a head of water is produced that increases the turbine's efficiency.
The phenomenon is called a'blockage'of the turbines and gets larger in proportion to the length of the fence.
Guy Houlsby, professor of civil engineering at Oxford university, says their design is an improvement on the vertical Darrieus wind turbine used in some turbine systems."
"The original Darrieus turbine has blades that are parallel to the axis of rotation, and that means that the loads in the blades are carried entirely by bending of the blades.
"The water flows at right angles to the axis of the turbine so, as the turbine turns, lift is generated by these blades,
"explained Houlsby. Peter Dixon, chairman of Kepler Energy, says the patented turbine is the most efficient yet designed.
According to Dixon,"the rotor is suited to lower velocity, shallower waters, which are areas where you can't put conventional axial flow turbines,
because to make them powerful enough you need to make them very big in diameter
So this turbine goes places other turbines cannot and generates electricity at an economical cost."
