Comments Off on 5 Innovations in solar technology capable of changing the face of entertainment

Sukrat Gupta: Solar energy Solar energy is probably the only form of energy that will continue to exist till the end of the solar system. Solar energy is fast becoming the most sought after type of energy for electronic devices. Solar power harnessing is no longer restricted to calculators or projects, but found real life applications. Not only are these energy sources non exhaustible, they are also non-hazardous, unlike lead acid and even pencil cells that are hazardous in nature and pollute the environment. Moreover, the cost of photovoltaic cells – ones that are responsible for converting solar energy into electrical energy – has come down in the world market and are now produced in large quantities, opening up new vistas for experimentation and application. Here we are discussing five Innovations in solar technology capable of changing the face of entertainment. 1. Solar-powered smartphones The first newest application of solar energy has been found in the smartphones – the world’s most selling electronic gadget. Using a third party product, one can convert the electrically charged battery into a solar energy charged battery. However, though this saves a lot of electricity, the extra products required for such a thing are large in size and quite heavy. Moreover, their performance and efficiency are still not up to the mark. Designing and testing are still going on so that one day, these photovoltaic cells will find their places in place of electrically chargeable batteries, without affecting the design, features and performance of the smartphone. 2. Solar-powered MP3 players Just like the smartphones, MP3 players can also have photovoltaic cells replacing the traditional rechargeable batteries. What makes this prospect even more interesting is that these photovoltaic cells will not need a battery, which frees up space for addition of more circuitry that can be used to enhance the performance of the player or increase the storage memory to incorporate more songs, data and videos. 3. Solar-powered batteries Solar energy may not need solar cells to be harnessed, but there are cases when it is not possible to run a device without power backup for long. Created for laser tag blaster by Wu Jian, this award winning concept talks about having two small solar panels exposed to the sunlight, while the third panel is used for power in the device. Once the power of this source runs out, wrap up one of the panels and put it inside the battery slot, and the operation of the device will continue. Such a concept is very useful during rainy seasons or nights. 4. Photovoltaic planes The world is reeling in fuel crisis and planes are using enormous amounts of fuel continuously. In order to reduce pressure on the conventional sources of energy, photovoltaic planes are being tested in leading laboratories and industries. These planes will not work on photovoltaic cells, which may prove insufficient for operation. They, however, are using different technologies to harness solar energy for their operation. A Swiss company, Solar Impulse has come up with a plane that is light weight and operates on solar energy. What is so incredible about this plane is its ability to fly for 36 hours continuously, even when there is no sun in the horizon. 5. Solar-powered yacht For those who love to sail on yachts and explore the seas, the world is trying to gobble them up. It is not the reason of jealousy, but the reason of useless fuel wastage for amusement. In order to reduce fuel consumption, some companies, like DSe, are trying to come up with solar-powered yachts. These yachts run on solar energy during daytime and diesel engines at nights. In this way, fuel can be saved for one half of a day, which is a significant amount. The main drawback about these models is that they are much costlier than an average yacht, making it nearly impossible for most of the people to lay their hands on these vehicles. Another company, PlanetSolar, has come up with a solar-powered yacht that can circumnavigate the planet.

Comments Off on Five most amazing pedal powered boats

Apara Bhattacharya: Amazing pedal powered boats Most amazing pedal powered boats Boats were the conventional means of transport that is nowadays a great choice for the eco- conscious generation. Although you cannot deny the drawbacks of boats in comparison to the modern automobiles, if you are solely focused on the level of pollution imparted by the modern vehicles and that of boats, the latter always tops the list of most effective means of transport that causes almost no pollution. Boats are better regarded as human powered water vehicles that can be both human driven and motor driven. Not only this, boats also vary according to their construction, function and capacity. Thus, while on one hand simple and conventional boats, driven by two boatmen or a single boatman in there, pedal boats are also there on the other hand. Likewise submarines, hydrofoils, etc. are also there in the category of water crafts. Here are five boats that run on pedals and are unique in their own ways. 1. WiTHiN pedal powered boat WiTHiN WiTHiN – a pedal powered boat This is a boat that runs on human power and has the ability to stride across the ocean. This human powered boat, Ocean WiTHiN draws its inspiration from the water craft, WiTHiN. The body of this water vehicle is made from fiberglass which are in the form of flat carbon fiber panel that are stitched together to form the hull at the bottom. The base of the same comprises of a double kayak hull, which was donated to the designer of WiTHiN by Steve Schleicher of Nimbus Kayaks and sponsor and adviser of PedalTheOcean. The designers of this boat are Rick Willoughby and the award winning naval architect, Stuart Bloomfield. 2. Solar and Human Powered Concept Boat Solar and Human Powered Solar and Human Powered Concept Boat This boat has been designed by the French designer, Jonathan Mahieddine. This is solar powered boat that has the dual function of running on human power as well. The most notable feature of this boat is that unlike the conventional boats it targets at zero noise emission while floating on the water. The unique appearance of this boat has a wide deck that is a great option for relaxing amidst nature with your whole family, while having a wide view of the ocean. Moreover, you can also enjoy sunbathing while on boards. The human operated oars are also beneficial for exercising your hand muscles while floating in the ocean. But when you feel tired, switch over to the solar powered mode and let the boat sail by the energy it has accumulated in its solar cells throughout the day. 3. Torpedalo designed by Bentley engineers Torpedalo Torpedalo designed by Bentley engineers This boat is a combined creation of two engineers from Bentley, who have the aim of crossing the Atlantic this December in their self made boat, thereby covering more than 3000 miles in ocean and setting a world record. The designers of this boat are Mark Byass and Mike Sayer. They will have a competition with twenty five such racing boats in the world championship known as Woodvale Challenge Atlantic Rowing Race. The boat, Torpedalo, which they have made, features a fiber glass body, which is made from carbon fiber panels. It has a length of nine meters and is also equipped with solar panels for capturing green energy from the sun and using it to produce fresh water by desalinating ocean water and also to empower devices that they will carry on board, such as GPS, radar, satellite phone, etc. 4. Ilha by Alexandre Bellerose Zero-emission pedal-powered boat concept Ilha Ilha by Alexandre Bellerose Zero-emission pedal-powered boat concept Now water rafting is going to be more fun with the help of the green boat that will not harm marine life as conventional water vehicles do by toxic emissions and awful noises. This boat has been designed by an eco conscious designer, named Alexandre Bellerose and is human powered. The passengers on board are supposed to pedal the boat and make it cut through the waters and move ahead. The extended feature of this boat are that it has a light weighted, folding foundation, which when stretched, becomes almost an small private island for those on board and provide them opportunities for various water activities. Together with it, water rafting in summers is also pleasant in this boat as it has a folding umbrella that collapses to become a fan so that the occupants can adjust the exposure to sun as per their choice. 5. Waterbug by Garry Hoyt and the Harken brothers Waterbug Waterbug by Garry Hoyt and the Harken brothers This is a strange looking boat, made by the nautical manufacturer, Fisheries Supply. It is an outcome of the joint venture of yacht designer and sailing innovator brothers, Garry Hoyt and Harken. The body of the boat is made from roto molded material and has a two seated option. It also features an electric propulsion package.

The good, the bad and the ugly about vertical axis wind turbines

Comments Off on The good, the bad and the ugly about vertical axis wind turbines

Leka Ram: Vertical axis wind turbines Main rotor shaft is set vertically and the main components are located at the base of the turbine Vertical wind turbines look completely different from the conventional wind turbines that have blades rotating on the horizontal axis. The vertical turbine can be compared to a coin spinning on its vertical axis. Modifications in the design and structure have been done for improving the performance and serving more benefits. The major parts of the vertical wind turbine are a rotor shaft that is arranged vertically, a vertical wind generator located near the ground, a gearbox also located near the ground and the blades that are two or three in number. These wind turbines are being improved in terms of function and design for enjoying more advantages. There are different types of vertical axis wind turbines such as; Darrius turbine : Named after George Darrius, the French inventor. The turbine is known for its efficiency. However, it is criticized for the low torque. It requires an additional rotor to start it. Gorlov Helical turbne : This turbine is designed in a helical configuration and was built to deal with the problems in the Darrius turbine. They are self-starting and reliable. Giromill : It is a variation of Darius turbine. It offers high starting torque and variable pitch. The blades used in this type of turbines are curved, straight or v-shaped. Savonius turbine : The turbine has helical scoops for providing smooth torque. Most of these are self-starting. Apart from these there are many other types such as the neo-aerodynamic turbine, quiet revolution turbine, novel turbine and zephyr turbine. The good Low Cost Lower construction and transportation costs 1. The energy generation with the vertical turbines cost is less and comes to about 2.5-3.5 cents for a kilowatt hour when compared to the 4-5 cents per kilowatt hour. 2. These turbines can handle high wind speeds. The maximum speed for harvesting the energy from wind is 28-33 mph. With the vertical design it can produce electricity from winds with a speed of 70 mph. The design can be used in areas with very strong winds. 3. One of the major problems with the conventional wind mills is that they kill the birds that come in their way. The design of the vertical turbine looks like a solid structure keeping the birds away from it. 4. The new device blends well with the environment. It can be painted in such a way that it blends well with the surroundings. Being smaller they can be installed in areas where huge structures cannot be used. 5. Another advantage is that the generator can be easily accessed for service. There is no magnetic field resonance, interference with communication or aircraft navigation and no ground resonance. 6. They function quietly too. Can this be better? The major difference between the vertical and horizontal wind turbines is the position of the blades. In the horizontal model the blades are mounted on the top while in the vertical model they are at the base of the tower and close to the shaft. The main advantage is that they can be mounted close to the ground making it beneficial for residential purposes. The bad Inefficiency Blades constantly spinning back into the wind causing drag 1. When compared to the horizontal turbines, these vertical axis wind turbines are able to produce only about 50 percent of the energy. 2. Since no tower is required for the structure, they are not able to take advantage of the high wind speeds usually available on elevated and higher areas. 3. Some energy is required to start the device because of the low starting torque. 4. If any part of the device is damaged, the entire structure has to be disassembled for changing it. 5. Wires are required for holding the complete structure in place. 6. The vertical wind turbines have a complicated structure with high rate of failure. 7. Wind efficiency is low and costs higher. Can this be avoided? New designs of the vertical axis turbines are being made in order to deal with the problems faced by the earlier designs. More research and analysis is still required to develop a turbine without the above mentioned drawbacks. The ugly Bird Killing Wind turbines affect migratory birds Though wind energy is considered to be one of the renewable and dependable sources of energy, there are several downsides to this. 1. Wind is not dependable. To turn the blades you need wind. If there is no wind they cannot function effectively. They are great only for areas where you can have wind all through the day and year. They may be useless in areas where wind is less. 2. One of the best places where you can get wind all through the year is the coastal areas, mountain tops and valleys. All these areas are very expensive and it can be very difficult to afford the area first and then build the turbine also. 3. Many people consider wind farms as an eyesore. Though they are able to produce energy using the wind, many people do not like the idea of residing near a wind farm. 4. Apart from that, the turbines are also known to interfere with the radio and television signals, kill birds and make noise. Why are we so critical Every new invention has its advantages and disadvantages. Similarly, the wind turbines faced some problems with respect to the availability of winds for turning the turbines, birds coming in between and so on. However, the researchers are trying to find solutions to each of these problems by creating new designs and using improved technologies. This gave rise to the vertical axis turbines. Though there are some negative aspects to this too, the researchers are striving hard to overcome them. Wind is everywhere. We need to make proper efforts to use it to the maximum in order to save other sources of energy and use the renewable sources in an effective way. The bottom line Wind energy is renewable. More and more devices have to be developed to harness the wind energy for generating electricity. The wind mills are efficient in generating energy. The type of turbines used depends on the area and the amount of power required in that particular area.
