1. 0:00imagine this the world's oceans Seas
2. 0:03lakes and rivers which made life on this
3. 0:05planet possible and are the Beating
4. 0:07Heart of planet Earth's biosphere and
5. 0:09ecosystems can also provide Humanity
6. 0:11with infinite cheap and green
7. 0:14electricity everyday Humanity wakes up
8. 0:16to new Innovations in the green power
9. 0:18sector most of these Innovations are
10. 0:20related to solar and wind power however
11. 0:23in recent years we've been hearing more
12. 0:25and more about ocean wave energy sadly
13. 0:28this sector is not actually new and
14. 0:31inventions for the effective utilization
15. 0:33of water movement in the oceans seas and
16. 0:35massive Lakes for the production of
17. 0:37green electricity has been around for a
18. 0:39while but are not implemented on a large
19. 0:41scale the ocean currents waves and Tides
20. 0:45never stop and combined can produce more
21. 0:47than enough electricity to power the
22. 0:48entire planet interestingly America's
23. 0:51coastlines alone could generate up to
24. 0:532.64 trillion kwatt hours of energy
25. 0:56using today's Technologies this means if
26. 0:58the technology is improved proved that
27. 1:00amount could be doubled with even fewer
28. 1:02Coastal wave Farms today we're going to
29. 1:04look only at wave energy and how it
30. 1:06alone can provide the world with more
31. 1:08than half of its energy
32. 1:13needs the science behind Oceanic wave
33. 1:16energy is simple the world's oceans and
34. 1:18seas are constantly producing waves that
35. 1:20never cease these waves movement can be
36. 1:23harnessed in various ways and turn into
37. 1:25electricity it's an Infinite Source too
38. 1:28because as long as the Earth continues
39. 1:29to travel around the Sun and the Moon
40. 1:31around the earth waves will continue to
41. 1:33be a viable source of kinetic energy the
42. 1:36amount of energy produced from waves
43. 1:38depends on several factors other than
44. 1:40the quality and efficiency of the
45. 1:41technology used to harness it things
46. 1:43such as the waves height speed length
47. 1:46and density even though these factors
48. 1:48are unpredictable still even the
49. 1:50smallest waves can produce electricity
50. 1:52it's similar to how wind and solar power
51. 1:54are dependent on factors such as wind
52. 1:56speed and the amount of sunlight unlike
53. 1:59solar power which cannot be harnessed at
54. 2:01night and during winter while clouds
55. 2:03block the Sun and wind energy which
56. 2:05stops in the absence of winds wave
57. 2:07energy rarely stops and actually
58. 2:09increases during winter and harsh
59. 2:10weather in terms of physics the oceans
60. 2:13and seas have a lot more potential
61. 2:14energy for capture than the wind because
62. 2:17potential energy is calculated using
63. 2:18mass and velocity thus Oceanic waves
64. 2:21have more potential to transfer more
65. 2:23energy since water has more mass and is
66. 2:25denser than air in recent years major
67. 2:28improvements in the Technologies used to
68. 2:30harness wave energy have been achieved
69. 2:32so let's take a look at some of these
70. 2:33Amazing
71. 2:35Inventions we have to admit the
72. 2:37Technologies for this sector are still
73. 2:39being improved the basic concept is to
74. 2:41capture wave energy using devices that
75. 2:43are placed on the surface of the ocean
76. 2:45or submerged in the water these devices
77. 2:48are simply designed to move with the
78. 2:50motion of the waves and convert the
79. 2:52kinetic energy of the waves into
80. 2:54mechanical energy which is turned into
81. 2:56electricity via generators these devices
82. 2:59which are placed in groups represent
83. 3:01what are called wave energy Farms that
84. 3:03are connected to the power grid the
85. 3:05great news here is that more than 50% of
86. 3:07the world's population lives close to
87. 3:09coastal areas hence it's easy to connect
88. 3:11such Farms to the power grid there are
89. 3:14several methods for harnessing wave
90. 3:16energy including placing electricity
91. 3:18generators on the surface of the ocean
92. 3:20utilizing the up and down motion of
93. 3:22waves to power pistons and turn
94. 3:24generators using submerged buys using
95. 3:27submerged panels using oscill in water
96. 3:30columns that use waves to move air to
97. 3:32move turbines and using floaters that
98. 3:34are attached to existing structures such
99. 3:36as break Waters peers or Jetties to
100. 3:39capture the energy of ocean waves some
101. 3:42of the most recent advancements in the
102. 3:43field include boys that float on the
103. 3:45surface of the water and are anchored to
104. 3:47the seabed these boys contain power
105. 3:50takeoff systems that convert the motion
106. 3:52of the waves into electricity which is
107. 3:54then transmitted to shore via an
108. 3:56underwater cable other types of buoys
109. 3:58are connected to pump pumps that drive
110. 4:00high-press water through onshore
111. 4:02turbines generating electricity there
112. 4:04are also buoyant structures that
113. 4:06oscillate and resonance with the
114. 4:07incoming waves driving a power takeoff
115. 4:10system that generates electricity and
116. 4:12there are also systems that use
117. 4:13submerged panels to capture the energy
118. 4:15of ocean waves the panel moves back and
119. 4:17forth with the motion of the Waves
120. 4:19driving a hydraulic piston that
121. 4:21generates
122. 4:22electricity there are also advancements
123. 4:24in fixed floater systems which consist
124. 4:26of floaters attached to existing
125. 4:28structures so such as breakwaters peers
126. 4:31Jetties or anything that is smashed by
127. 4:33the ocean waves regularly to capture the
128. 4:35energy of ocean waves the floaters move
129. 4:38up and down with the motion of the Waves
130. 4:40driving hydraulic pumps that generate
131. 4:42electricity and of course China is ahead
132. 4:45of everyone else they recently installed
133. 4:47a very Innovative 6,000 ton energy wave
134. 4:50converter called the nanun mobile power
135. 4:52bank this amazing machine can generate
136. 4:55up to 24,000 kwatt hours of electricity
137. 4:57per day which can feed more than 3500
138. 5:00homes with
139. 5:01electricity this new invention
140. 5:03represented a major Leap Forward over
141. 5:05older smaller kilowatt scale wave energy
142. 5:07devices the system is being replicated
143. 5:10and distributed to remote coastal areas
144. 5:12and islands that are just too far from
145. 5:13the main Chinese power grit networks
146. 5:16additionally it's being used for blue
147. 5:18economy projects that also tend to be in
148. 5:20isolated remote coastal areas or very
149. 5:22far from the shores the nancun device
150. 5:25consists of a semisubmersible platform a
151. 5:28hydraulic system power generation system
152. 5:31a control system and a moing system by
153. 5:34absorbing the waves from the semi
154. 5:36submersible platform and utilizing their
155. 5:38energy through the independently
156. 5:40developed energy conversion system the
157. 5:42device achieves a three-stage energy
158. 5:44conversion from wave energy to hydraulic
159. 5:46energy and then to electricity needless
160. 5:49to say this device and other
161. 5:50Technologies are constantly evolving and
162. 5:52improving however some serious obstacles
163. 5:55still need to be effectively
164. 5:57tackled developing testing and deploying
165. 6:00new wave energy devices is a very
166. 6:02difficult process and the reasons are
167. 6:05obvious the number one obstacle is the
168. 6:07ocean itself oceans are constantly
169. 6:09moving waves can fluctuate from a few
170. 6:12inches in height to a few feet or even
171. 6:14meters depending on the area during the
172. 6:16same day and mirr hours apart during
173. 6:18both winter and summer the oceans are
174. 6:21simply inhospitable and waves can easily
175. 6:23damage wave energy devices even
176. 6:25submerged devices aren't spared as the
177. 6:27current can pull and push the system
178. 6:29systems and render them useless if not
179. 6:31wrecked Additionally the oceans eat away
180. 6:34at everything and anything rust issues
181. 6:36are big headaches and steel parts have
182. 6:38to be periodically treated and recoded
183. 6:40to prevent erosion salty Ocean Mist and
184. 6:43water are also notorious for decreasing
185. 6:45the longevity of electrical and
186. 6:47electronic systems this means such
187. 6:49components and wiring have to be sealed
188. 6:51in a manner that effectively prevents
189. 6:53water damage so here's the pickle these
190. 6:55two issues combined mean that effective
191. 6:57and feasible wave energy device es have
192. 6:59to be ultra strong and rust resistant
193. 7:02and the electric and electronic
194. 7:03components have to be water resistant
195. 7:05and sealed such devices also have to
196. 7:08last for decades with a minimum amount
197. 7:10of Maintenance or very low maintenance
198. 7:12costs to make them commercially feasible
199. 7:14on a large scale these issues have to be
200. 7:17resolved before corporations invest in
201. 7:19larger scale projects that can be
202. 7:21connected to the grid do you think wave
203. 7:23energy Farms will pop up in coastal
204. 7:25areas in the near future and why is the
205. 7:27sector so far behind wind and solar
206. 7:29power let us know in the comments
