As big believers in using the right battery for the job our range of Trojan batteries are becoming more and more popular for marine and canal boat applications. It seems word gets about within the marine/boating communities and when it comes to Battery power lots of people have different opinions but when it comes to Trojan the message is clear. They do the job for heavy use.

Trojan's range of 6 volt Traction batteries have been around for some time. Tried and tested albeit old fashioned technology seems to prevail when it comes to battery power needed for domestic and heavy boat use. Alpha Batteries is proud to be appointed a Major UK On line Retailer of these batteries. We tend to find loyal Trojan customers over the years will buy nothing else and due to the high quality do not have to buy them often. Bad for us I suppose!
We have also found a large surge in customers enquiring about the product or calling us for advice in which we can 100% recommend the Trojan range. We tend to find customers that have purchased traditional budget or standard Leisure Batteries for Domestic Boat use are now looking for something better, something that lasts. Yes they do cost more initially perhaps but in the long run the savings against having to buy standard leisure batteries every 12-24 months. Science aside (for another day) at the very heart of the Trojan range lies extra thick plates and this is the key. Its all about how low you can discharge the battery and how it copes thereafter. The Trojan range can be safely discharged by 80% and recover without loss of capacity something standard leisure batteries simply can not do. If you repeatedly discharge a standard 12v 110ah battery it will be down to 50ah within a matter of months and you will be left scratching your head as to why the TV won't stay on as long, why the fridge keeps going down or why the heater has gone off. Sound familiar?

As mentioned in our leisure battery post. Leisure batteries are designed for leisure time use (1-2 months). If you live on your boat or use it often you need Traction batteries and Trojan are as good as they get. Please feel free to contact us or see our range here Trojan Batteries  .

What Issues Affect Output of Wind Turbines?

Wind energy will undoubtedly be the cleanest form of making power from renewable sources. There’s no pollution, no fossil fuel burning, and unless something extremely dramatic occurs, you do not run out of any wind. However, it isn’t like you could erect wind turbines anyplace and they’ll begin generating power. There will be a lot of factors which could make a huge impact upon the quantity of energy generated out of wind.

Wind

Them being wind turbines, their output initially depends upon the wind. The force and speed of the wind could be deciding issues. The more wind force and speed you possess, the larger the quantity of power the wind turbines will generate. Various areas possess various wind speeds. You could collect the obtainable wind dynamics information and utilize a model such as Webull Distribution to calculate how efficient the wind of a specific area will be.

Height

Locations of high altitudes possess more wind because of a variety of environmental issues. Besides, within higher locations there’s less obstruction from the surrounding buildings, trees and hills. As a matter of fact the height will be so vital that the alternative energy engineers and scientists are attempting to utilize kites (because of the heights they could reach easily) to tap wind power.

Rotor

The quantity of energy made by a wind turbine will be proportional to the size of a rotor utilized, as every additional factor has been taken within consideration. A larger rotor will generate more power. Though it might be priced more, within the long run, as you’re getting a wind turbine erected, choose as big a rotor as probable.

Is It Probable To Convert To Full Wind Power?

With every bit of the chatter of being green, the question was thrown out on several occasions if there’ll be a period we could utilize nothing except renewable energy in order to power the world. A smaller island inside Denmark is attempting to answer that with a “yes” as it powers up each day using nothing except wind power.

This Danish island is the perfect scene as the wind never ceases to blow. The North Sea provides the ideal chance of capitalizing upon the winds which come off the sea and for them to utilize wind power as their main power source. In fact, wind power they’re utilizing is their sole power source.

Samso Island possesses around 4,000 individuals who live upon this island and they possess a direct stake into how well the project works. These residents include those who have ownership in shares within many of the windmills being utilized to power this island. That being said, they do not care about the windmill noises as the blades whip around to develop electricity.

Naysayers argue that it’s good on this island, yet how would it work within a city? The naysayers need only to know that the “island” is larger than Manhattan in New York. It provides hope that sometime in the future, irrespective of the size or location, that a whole United States city could utilize some type of renewable energy to obtain their power. To have the ability to erase the whole carbon footprint could really be a reality.

The one aspect holding most of the projects back includes the financing aspect. They could be very expensive to get going, yet due to islands such as Samso, improvements continuously are being made and over a period of time, costs will decrease. We only have to keep plugging away and at some point, the world will get used to a greener method of thinking.

You have possibly viewed calculators that had solar cells – devices which never require batteries and within a few instances, do not possess an off button. So long as there is an adequate amount of light, they’ll seem to last forever. You might additionally have viewed bigger solar panels, maybe upon buoys, call boxes, emergency road signs and within parking lots in order to power the lights.

Though the larger solar panels are not as typical as those solar-powered calculators, they are obtainable and easy to notice if you understand where you to search. As a matter of fact, photovoltaics – once utilized nearly exclusively within space, providing power to satellites’ electrical systems since 1958 – are being utilized more within less exotic methods. This solar panel technology continuously pops up within newer devices frequently, from electric car charging stations to sunglasses.

The expectation of a “solar revolution” has been around for years – the thought of one day using free electricity powered by the sun. It’s a seductive promise, due to on a sunny, bright day, the sun’s rays emit around 1,000 watts of energy a sq. meter of the earth’s surface. If it was possible to collect every bit of that energy, we might easily power our offices and homes for free using solar panel technology.

Developments within Solar Panels Cell Technology

Problems with cost-effectiveness spurred countless research efforts targeted at fine-tuning and developing newer methods of making solar power growingly competitive with conventional energy resources.

For instance, single-crystal silicon is not the sole material utilized within PV cells. Polycrystalline silicon will be utilized within an attempt to slash manufacturing expenses, though resulting cells are not as effective as single crystal silicon. The second-generational solar cell technology will consist of what is referred to as the thin-film solar cells. As they additionally usually sacrifice a bit of efficiency, they are cheaper and simpler to make – and become more effective all the time. The thin-film solar cells could be created from various materials, involving amorphous silicon (that possesses no crystalline structure), cadmium telluride, copper indium diselenide, and gallium arsenide.

An additional plan for raising effectiveness is to utilize more than one layer of various materials with differing band gaps. Keep in mind that depending upon a substance, photons of various energies will be absorbed. Therefore, by stacking the higher band gap material upon the surface in order to absorb higher-energy photons (permitting low-energy photons to become absorbed by the low band gap material underneath), higher efficiencies may result. These types of cells, referred to as multi-junction cells, could possess more than a single electric field.

The concentrating photovoltaic technology will be an additional promising industry of development. Rather than merely converting and collecting a part of whatever sunlight happens to shine and become converted within electricity, the concentrating PV systems utilize the addition of the optical equipment such as mirrors and lenses to concentrate larger quantities of solar energy into highly effective solar cells. Though the systems are usually more expensive to produce, they possess numerous benefits over traditional solar panel setups as well as encourage further development and research efforts.

All of these various versions of the solar cell technology have businesses imagining products and applications which run the gamut, from everyday things such as PV-powered laptop cases, clothes and curtains to space-based power stations and solar powered planes. Not even the tiny universe of nanoparticles is left out, and researchers are exploring the probability for organically made solar cells.
