This will result in a substantially constant buoyant force over those depths as well. Buoyancy is a well understood phenomenon. Maintaining the balloon 100 at a constant volume has the advantage that the buoyant force on the balloon 100 will be constant as well. In order to avoid this shrinking volume issue, the balloon 100 can be pressurized so that its internal absolute pressure matches, or exceeds, the absolute pressure at the deepest depth at which it will be lowered. A constant wind will increase the net force on the balloon and thereby increase the power storage capacity for a given tether length. The net would extend a series of cables 212 which would merge with the tether at a strong junction 214. This structure is a good balloon structure for embodiments of submerged systems described in the present disclosure. It is possible to generate net revenue by buying electricity when demand is low, such as at night, and selling it when demand is high.

9, the reel and motor and generator system 1 12 are placed on land 131. The balloon 100 is lifted by an incoming wave 140 moving in the direction shown by the arrow 142. This pulls on the tether 102 in the direction indicated by the arrow 144. The tether is connected to the reel 108 on land 131 by a series of pulleys 104 anchored to the seabed 106. The pull on the tether 102 causes the reel 108 to spin in the direction indicated by the arrow 156. This causes the generator 120 to spin, making electricity. 3a-3c. In order to store energy in the system (charging), electricity is used to turn a motor 118 that turns the reel 108 in the direction indicated by the arrow 122 and pulls on the tether 102. Como quitar dolor muscular . The tether 102 pulls the balloon 100 in a downward direction, indicated by the arrow 124, against the buoyant force, indicated by the arrow 126. When the balloon 100 is pulled as far down as possible, as shown in Fig.

The system would be reeled out whenever currents are strong, pulling on the balloon and generating electricity, and reeled in when currents are weak. 5a where an energy storage system 92 has multiple balloons 100, where each balloon 100 is connected to a tether 102, and the tethers 102 are bundled together into a group 135, which is connected to the generator and motor system 1 12 on shore. This works because the reel provides rotary motion for a generator when the balloon is allowed to rise, and this rotary motion can be used to spin the generator that the turbine normally spins. Alternatively, the reel can be connected directly to an AC power generator which would not be phase matched to the grid. In accordance with one embodiment of the invention, an apparatus for converting kinetic energy to electrical energy comprises an energy conversion module having an attachment member and first and second components which provide electrical energy when moved relative to each other, the first component being fixed in position relative to the attachment member and the second component being free to move in at least one dimension within a predetermined range relative to the attachment member; an anchor that is fixed in place when deployed; and a flexure member connecting the anchor with the energy conversion module, the flexure characterized by mechanical properties that permit the energy conversion module to move in an oscillatory manner in response to external stimuli, whereby the first and second components are moved relative to each other and electrical energy is produced.
A ballast sack 1381 can be attached to the pulley 104 which could then be filled with earth or another ballast 1382 during installation of the balloon at sea to create a ballast 138. A barge 1383 carrying ballast could employ a chute 1384 to fill the sack 1381 with ballast. For example, if the balloon is reeled in during a period of high current, then the motor will have to do extra work to overcome this current. 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.

Wind plays the same role in an aerial balloon based system as water currents plays in a submerged system. An open ball bearing system where water was allowed to flow freely through the bearings would be simpler to make. This eliminates the need to have a motor from the storage system and can further reduce cost and potentially increase efficiency. There is a very significant cost advantage to having the reel and motor-generator unit (or a motor unit distinct from a generator unit) on land because this alleviates the need to do any maintenance to these more complex mechanical/electrical units underwater and furthermore eliminates the need to run electrical cables underwater. The tether 102 is connected to, and wound on, a reel 108 that is operationally connected, for example by a shaft 1 10, to a generator and motor system 112. Without departing from the scope of the present disclosure, the reel, generator and motor can be disposed on the seafloor or, as shown in Figs.

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. In the examples shown in above-described Figs., a single balloon 100 is shown attached to each tether 102. In reality, as shown in Fig. This is shown in Fig. 8a. Dolor debajo de la rodilla parte interna . When the wave 140 arrives at the site of the system, it lifts the balloon 100 and the barge 1 14 (Fig. It should be noted that for the same tether length and balloon diameter, submerged air filled balloon based systems can store almost 900 times more energy than systems based in the air. This same process can be employed for both submerged and aerial power storage systems. The characteristics of the oscillatory motion of the energy conversion module are a function of the shape of the energy conversion module housing (203), the length of the flexure (104), the iigidity and resilience of the flexure, and other factors.
These factors may be considered when designing an energy harvesting module for a particular purpose in order to efficiently produce a desired amount of electrical energy composed of a given range of current and voltage, For example, the force versus range characteristic of the flexure may be selected to be a harmonic of the anticipated energy source, Similarly, the range of motion permitted by the slide tracks in the energy harvesting module may be selected to accommodate the anticipate range of motion of the flexure, e.g., so the coils or magnets do not move all the way to the end of the slide track. This barge could then be weighed down and sunk to serve as an anchor for the system. This configuration provides a friction fit against the borehole or pipe wall in order to temporarily or permanently anchor the energy harvesting device in place.
