Exploring Cuba

travel

It doesn’t matter how good your passport photo looks, you will need a Visa to enter into Cuba.  I recommend visiting your governments  websites for up-to-date information on how to obtain a Cuban Visa.

Now that is out the way, let’s look at some of the interesting facts about Cuba.  Tourism is the country’s main industry, which is good news if you plan on visiting the country.  It has an excellently high literacy rate with a centralised socialist government.  For those seeking a cultural visit, there is plenty of free revolution art deco architecture and good interiors with a vibrant arts scene and Cuba’s legendary musicians.

Havana is the capital of Cuba, and no trip to this country would be complete without a visit to this city.  Havana has handsome streets unspoiled by shops and restaurants.  They have taken great care with urban development and tried to keep its numerous 1950s landmarks as they always have been.

Cuba has a hot and sunny tropical climate, with an average yearly temperature of 24°.  September and October are the most threatening months of the annual horror cane season that runs from June to November.  The peak tourist season in Cuba runs roughly from mid-December to mid-March and all July and August.  Prices can be higher during these times, so please be aware of this.

It is not possible see everything that Cuba has to offer in one visit, from lively festivals and delicious local cuisine to natural wonders and stunning architecture, there are many highlights that you must not miss on a visit to Cuba.  Make sure you spend some time lazing about on some of the best beaches in the crew be in.  It has golden sands palm trees and brilliant blue and green waters.  A nice cold refreshing mojito might just be the ticket after a hard day on the beach.  This is tubers iconic cocktail.  Make sure you visit one of the most well preserved colonial centres in the Americas, with postcard perfect buildings dotted throughout its narrow streets and historic classes.

Driving around in the vintage American car is a must do when visiting Cuba.  You won’t soon forget the first drive in this frozen in time vintage car.  Havana has many weekly street parties where music, barbecues and beer stalls are an ideal opportunity to meet locals.

If you’re a diver then you will enjoy the Cuban unspoiled coral reefs and other dive sites around the Cuban islands.  They are known as one of the best places in the Corinthian to go scuba diving.

Although Cuba is becoming more firmly established on the crew in tourist circuits, there are still not as many direct flights as one might expect.  It’s easier to get to Cuba from Europe or Canada than say the US.  If trying to arrive in Cuba from the US, you might find your passage is fraught with problems and best avoided.  That said, there are several airlines flying to Cuba and with a little planning, you should have no problem in picking up a flight to suit your budget.

 

Hydropower

The earliest references to waterwheels date from about 6000 years ago in Greece.  Many other cultures used the power of water moving down rivers or streams.  First application of hydropower was properly raising water from a river or stream silicon flow into a field to irrigated.  What power has been used to grind grain, treat cloth, and Tan hides.  Many sawmills and metalworking mills were also powered by water.  Today we use electricity generated from hydropower extensively.  Nearly 20% of the world’s electricity is generated by hydropower.

Way hydropower works is that water is carried by clouds and deposited on high elevation lands which collects in lakes and rivers.  Its natural path downstream and back to the ocean is interrupted by dam or other device to collect and hold the water.  A pipe brings gravity fed water to lower elevations where returns are turn turbine that runs a generator.

The amount of power generated by dam depends on the amount of water available and the height of the dam.  The greater the vertical distance the waterfalls means the more potential energy is there.  There are benefits with hydropower, such as no cost for fuel.  And the fuel is constantly renewable.  The reservoirs created to hold water also make great places for people to waterski, fish, and enjoy other aquatic activities and a great outdoor lifestyle.  This sounds great, but there can be disadvantages as well.  For example, it is difficult to increase the supply of energy produced by existing hydroelectric projects.  Building dams is very expensive and has high environmental impacts.  The environment can be changed dramatically by blocking the flow of water in a river which robs the lower sections of land of water.  River silt and sediment that is carried by the river are not deposited along the river or out to sea but instead it stays in the still water of the reservoir.  This can cause downstream riverbanks to a road.  Dam can also block, fish and other quick why from moving upstream and downstream.  To alleviate this fish ladders have been built to help alleviate the problem.  This only works for speedy sees that confined and navigate the ladders.

 

With all these benefits and disadvantages, large dams are very controversial.  However, small-scale hydroelectric plants can provide electricity in remote locations with minimal impact on the environment.

 

There are several different waterwheel designs.  The oldest and least effect to is an undershot will.  In this design the wheel turns only as fast as the river runs.  Undershot wheels capture about 20% of the available energy.  There is an overshot wheel, which has the water coming in from above the wheel in a trough.  The water spills out of the trough and hits the top of the wheel as it falls.  Both the downstream immense of the water and the energy transmitted as it falls help drive the wheel.  This will is about 70% efficient.  In breast shot wheel, water is carried in by a trough and hits the wheel about halfway from the top.  It uses bucket like containers to capture the energy of the passing water.  This type of wheel is about 35% efficient.

 

 

Large dams like the Hoover Dam in the United States of America supplies water to drive 17 generators, which produce over 2000 MW political power.  This power is delivered to cities and helps to create and grow jobs for engineers and electricians, such as Ballarat electricians.
