Flekosteel mercado libre mexico, flekosteel balsamo - YouTube Instead of, or in addition to electricity, combustion engines, hand cranks, wind turbines, or any other suitable mechanism can be used lower the balloon 100 in the water to charge the system 90, and the output energy (or power) of the system can be used mechanically as well. The buoyant power storage systems can be coupled mechanically to hydro power systems, nuclear power systems, or to any power system where rotary motion is used to spin a generator and make electricity. 13B. This creates a buoyant force and causes the balloon 204 to rise, pulling the tether 102 in the direction shown by arrow 208 and turning the reel 108 mechanically coupled to a generator.

When the wave passes, the balloon is pulled up and there is a momentary increase in force that will cause the mechanism to begin reeling out the tether, turning the generator. If the balloon is designed to operate at depths where the absolute pressure is 21 bars (200 meters underwater) then the relative pressure between the inside of the balloon and the environment will be 20 bars. Additionally, at deep depths there will be high-pressure forces that could cause water to penetrate the sealed bearing compartments. If the pressure in the balloon is 1 atmosphere absolute pressure when the balloon is at the surface, then when the balloon is lowered by 90 meters the balloon will be subject to 10 bars of absolute pressure, and the balloon will necessarily shrink to one tenth its initial volume. The balloon can occupy an initial volume when subjected to atmospheric pressure, the balloon being filled with air at a first pressure, the balloon to be lowered in the water to a pre-determined depth, the water exerting a second pressure on the balloon at the pre-determined depth, the first pressure being greater than the second pressure to allow the balloon to substantially maintain its initial volume when at the predetermined depth.

The daily variations in price of electricity are generally relatively stable, but some real time tracking of price would allow for optimal operation of the energy storage system. In this way a larger energy storage system can be built which would have a large storage capacity. In order to keep the system stationary under currents, the ballast would need to be larger. Larger systems would employ many buoyant bodies in a large array, occupying a large area on the seabed. 1 and 2. An air filled balloon 100 is connected by a tether 102 to a pulley 104 that is anchored firmly to the seabed 106. Dolor en la parte interna de la rodilla al caminar . The system can be anchored to the bottom of any suitable body of water including, for example, a sea, a lake, river, or reservoir. The pulleys can be anchored by means of a concrete foundation or by piles or bolts driven directly into the seabed.

The pulleys 104 will need to resist the buoyant force on the balloon as well as any forces caused by currents or waves on the balloon, so the anchoring of the pulleys should be strong. A balloon filled with pressurized air at 1 1 bars of absolute pressure with a diameter of 10 meters will be subject to a buoyant force of approximately 5,000,000 Newtons. This will reduce the buoyant force on the balloon 100, since the balloon is displacing less water. This 500,000,000 Joules of energy can be recovered when the balloon is allowed to rise, spinning the reel and powering a generator. However, their widespread adoption is often limited by the fact that the energy that is produced by alternative sources is intermittent.

Fig. 7b shows an alternative embodiment to the balloon 209 of Fig. Wind plays the same role in an aerial balloon based system as water currents plays in a submerged system. This can happen if currents are unpredictable in submerged systems, or due to wind gusts in aerial systems. The rotary motion of the wind turbines can also be used to directly wind the reel, charging the storage system. An embodiment of an aerial based buoyancy energy storage system is shown in Fig. Improvements in energy storage systems are therefore desirable. 4, in the energy storage system 91 , rather than having the tether 102 connect the balloon 100 to the reel 108 and the motor and generator system 112 disposed on a barge, these may be positioned on land 131. Positioning the reel 108 and the motor and generator system 1 12 on a platform, or even on the sea-bed itself are also within the scope of the present disclosure.
