A large portion of the world's food is simply wasted by lazy humans. People in affluent countries buy more food than they need, so that much of their food goes rotten and must be tossed before it is eaten. Or they pile more food on their plate than they could possibly eat and much of the food ends up in the trash. Another major factor is corrupt or incompetent governments who hoard food among a select few, poorly distribute food, or refuse to adopt modern agricultural methods. Tyrants sometimes even use forced hunger as a way to subdue the masses or punish opponents. Science can make an acre of farmland amazingly productive, but it can't force a dictator to give back the food he has stolen from his people.

8) Anderson cycle is also known as?explain

9)propose and explain the synonym to the Claude cycle

10) Which component has the lowest efficiency?

Oscillatory motion is highest at the surface and diminishes exponentially with depth. However, for near a reflecting coast, wave energy is also present as pressure oscillations at great depth, producing microseisms.

 Wave height is determined by wind speed, the duration of time the wind has been blowing, fetch and by the depth and topography of the seafloor. A given wind speed has a matching practical limit over which time or distance will not produce larger waves.

Wave energy;  Kinetic energy that results from the oscillation of water is called wave energy. Wave energy is derived from wind energy, which derives in turn from solar energy. Wave energy can be much more concentrated than the solar energy.

Step-by-step explanation

1.Oscillatory motion is highest at the surface and diminishes exponentially with depth. However, for near a reflecting coast, wave energy is also present as pressure oscillations at great depth, producing microseisms.

2. Wave height is determined by wind speed, the duration of time the wind has been blowing, fetch and by the depth and topography of the seafloor. A given wind speed has a matching practical limit over which time or distance will not produce larger waves.

3. Wave energy;  Kinetic energy that results from the oscillation of water is called wave energy. Wave energy is derived from wind energy, which derives in turn from solar energy. Wave energy can be much more concentrated than the solar energy.

4. Water currents can be found in streams, rivers and oceans throughout the world. Water current is the rate of movement in the water, and ways to describe water current include its speed and direction

5. In the open/Claude cycle, water is the working fluid. The warm water surface water is caused to boil by lowering the pressure, without supplying any additional heat. The low pressure steam produced then, drive's the turbine and the exhaust steam is condensed by the deep colder water is discarded.

6. The working fluid chosen by Anderson OTEC cycle is propane. The operating pressures of such fluid at the boiler condenser temperatures are much higher than those of water being roughly 10 bars at the boiler, and their specific volumes are much lower

7. The closed cycle approach was first proposed by Bajrot in 1926, but the most recent design was by Anderson in 1960s. The closed cycle is sometimes referred to as Anderson cycle. The Anderson cycle chose Propane as working fluid.

8.  Closed cycle; Anderson cycle is also called as closed cycle. Closed cycle utilizes the oceans warm surface and cool deep waters heat source and sink respectively, 

9. Open cycle; A Claude cycle is also called as open cycle in which sea water itself plays, the multiple role of heat source, working fluid and heat sink.

10. OTEC power generation gives less efficiency. However, because of the OTEC requirement for parasitic power and other losses, the achievable net conversion efficiencies of 30 to 40% associated with conventional power plants.
