Interesting Sailboats: SOLAR PANELS ON SAILS
Saved by uncleflo on February 13th, 2022.
I don't sail but this idea interests me. Why couldn't a turbine of some description be fitted to the underside or even integrated into the keel to add to energy produced That is called an hydrogenerator and many oceanic sailboats use them. On the Vendee Globe, the non stop sailing race around the world most boats have two. They are expensive, with a price around 4/5000 euros. Finally somebody is working actively in what seems to be an obvious way to generate electric electricity on sailboats: Photo-voltaic sails. Till now the technology did not allow for panels flexible enough to allow that but on last years the technology has evolved a lot. It is already possible and it will not be expensive in the future. At least a sail manufacturer is working already actively on that, the UKsails France branch.

Showersave Stockists - Waste Water Heat Recovery System - QB1-21
Saved by uncleflo on February 9th, 2022.
Suitable for new builds, home extensions and retrofitting, the Showersave QB1-21 and Showersave QB1-21C use the heat from the water flowing out of the shower to warm up the cold water going in. This simple heat exchange mechanism means that you spend less money on electricity or gas heating up the water to your shower. Can also be installed under "shower over bath" plumbing situations. WRAS approved. The hot and cold waters are kept separate by the double walled copper pipe design. An efficiency of +60% depending on flow rate. The QB1-21 superseds the old RECOH-VERT RV3 system. The unit is exactly the same size, however the energy efficiency has been improved. The Cyclone Top Fitting increases the efficiency of the Showersave by making the hot waste shower water swirl around and down through the central copper pipe of the Showersave. This increases the amount of time the hot water is in contact with copper pipe to maximise heat transfer. Greater heat recovery is achieved with the Cyclone top.

Marine Lightning Protection Inc.
Saved by uncleflo on May 11th, 2021.
Given the wide range of potential issues with lightning protection of ships, it is not surprising that a common problem is that the agent does not understand how to define the most pressing concern. Ill defined Class regulations, use of ambiguous terms such as "lightning arrestor", and the widespread availability of devices with checkered histories do not help. To this end we offer a standard 20-hour consulting package that provides basic concepts, identifies prioritized issues, and develops the framework for an effective lightning protective process. Please email us with questions or details. Another fundamental problem revealed in this scientific work was that a one square foot ground plate is "hopelessly inadequate" to prevent sideflashes in fresh water.This was not addressed in these earlier standard rewrites since, at the time, there was no obvious solution. We can now solve this problem with our patented SiedarcTM electrodes that, when distributed around the hull, provide the multiple exit points needed for effective grounding.

Boat Lightning Attenuation Onboard
Saved by uncleflo on May 11th, 2021.
According to published reports, in the US out of the annual average of about 100 deaths due to lightning, approximately 13 are aboard boats. Suffice it to say that if lightning is a hazard where your boat will be used, a plan should be developed to deal with the possibility of a direct strike. In the Pacific Northwest lightning is relatively rare. In Florida, some areas annually have more than fifty strikes per square mile..! According to the well known lightning researcher Ewen Thompson, lightning can develop on the order of one hundred million volts, peak currents of tens of thousands of amps, and generate temperatures of some fifty five thousand degrees. Fortunately, it lasts only a fraction of a second, but within that time it can be deadly and / or very destructive. A lightning strike involves an extremely rapid change in an electric current, generating a momentary but extremely powerful magnetic field. This electro-magnetic pulse (EMP) will readily induce currents in adjacent wiring. Currents induced in wires by the EMP from a lightning strike may do some very weird things, such as fry every piece of electronics aboard. A strike nearby or on another boat can fry the electronics aboard your boat without even requiring an electrical connection or direct strike.

Ground source heat pumps - Designing Buildings Wiki
Saved by uncleflo on December 18th, 2019.
Heat is stored by the thermal mass of the ground of water thermal. There are two types of heat sources: In the UK just a few metres below our feet the ground keeps a constant temperature of about 11-12°C throughout the year. The Earth’s internal heat was originally produced during accretion. Since then heat has been produced by the radioactive decay of elements such as uranium, thorium and potassium. Due to its high enthalpy, this type of heat is often harvested in volcanic areas for electricity production and large district heating. The majority of heat stored right in the Earth’s surface comes from the sun. This heat is widely available, and because of its low enthalpy, it is often harvested for local heat pump applications.

Marine - Victron Energy
Saved by uncleflo on October 11th, 2019.
Whether you are a leisure or a professional sailor, you know how important it is to have a reliable power supply so that your electronics continue to function properly - especially far out at sea. Victron Energy offers a broad range of equipment designed specifically with you and your on board power system in mind. We proudly present to you a new era in freedom and independence. 'Service' batteries provide power for everything except for 'engine-starting'. Demand for on-board electricity has to be matched with an adequate battery bank. Lithium Batteries provide the best solution for high power demand. Compared to lead/acid technology they are smaller and about 70% lighter for their capacity. They can be deeply discharged, without harm. More current is available throughout the discharge cycle …and they can be cycled thousands of times - resulting in a much longer service life. It is also 'easier' to drive power back into Lithium batteries - so charging-time is reduced.

Sailing Uma - THE MOTOR
Saved by uncleflo on February 24th, 2019.
Many people have written in and commented that an electric motor is only good for day sailors who weren’t going very far each day, and that you need a reliable diesel engine for long distance cruising. But we feel like the opposite is true. Since we don’t have a dock to tie up to and charge our batteries each night, we rely on sailing to recharge our system. The longer we sail and the more sun we get, the more power we make. Because we don’t have a 9-5 to return to at the end of a fun weekend out on the boat, we have no schedules requiring that we make it back to the dock on time, no matter what the wind is doing. So, we feel that an electric motor, depending on your sailing style, can be adapted to any boat. But, you have to be willing to work around the one major draw back, range.

Wind Turbine Design
Saved by uncleflo on November 28th, 2018.
Primary objective in wind turbine design is to maximize the aerodynamic efficiency, or power extracted from the wind. But this objective should be met by well satisfying mechanical strength criteria and economical aspects. In this video we will see impact of number of blades, blade shape, blade length and tower height on wind turbine design. The next big factor which is affecting performance of wind turbine is shape and orientation of blade cross section. A moving machine experiences fluid flow at a different velocity than the actual velocity. It is called as relative or apparent velocity. Apparent velocity of flow is difference between actual flow and blade velocity. Absolute velocity of the flow is shown in first figure, while apparent velocity in the second figure. It is clear that apparent velocity of flow is vectorial difference between actual and blade velocity. The vector difference is shown in the first figure at a particular cross section. A rotating blade will experience an apparent velocity of flow.

Seiko Watches > Thermic
Saved by uncleflo on May 31st, 2018.
The world’s first watch equipped with a mechanism for thermal power generation. The thermal power elements generate electricity from the temperature difference between the body and atmosphere and store it as energy in a secondary battery. A full charge keeps the watch running for about 10 months. The Thermic generates electric power via the Seebeck effect, a phenomenon produced when heat transfers from the back of the case to the case surface. To improve energy efficiency further, a power-saving mechanism stops the second hand whenever the watch is removed from the wrist.

The Electric Car Charging Etiquette
Saved by uncleflo on December 15th, 2016.
The dos and don'ts of fuelling your petrol-saving vehicle. A few years ago, you could venture into some beneficent municipality and find — in the public garage, or the library car lot, or right in the middle of Main Street — a couple of plug-in electric vehicle (PEV) charging stations. These cities, along with college and corporate campuses, were demonstrating their commitment to preserving the environment, offering free power and prime parking to those citizens who were willing to spend a lot of extra money for a low-range, underpowered, unsexy vehicle. Those charger-augmented spots were often empty, simply because there weren’t enough PEVs on the road to fill them.

Transatomic - Let’s create abundant energy and a healthy world
Saved by uncleflo on July 14th, 2016.
The nuclear industry of the 1950s was defined by an inexhaustible optimism and rigorous scientific thinking. Anything was possible, and nuclear energy promised to power the world. Revolutionary designs were prolific. Today, however, this technological diversity has been narrowed, and the industry has become locked into one design: the light water reactor. We’re challenging this strategy and have returned to the beginning to explore another path, and another design – the molten salt reactor. This simple reactor design, updated with modern technology and materials, has the potential to revolutionize the nuclear industry.

This is a portable system that generates electrical power via an accumulator that provides the initial motion for the system. Two batteries are used in this system and the system is kept working via the initial motion provided by these batteries. There is no need for another transformer. This device works using its own mechanism and there is no need for additional devices. In this way, a continuous electrical power generation is possible. This device can work without connecting it to a network so it is possible to use it at places where electricity does not exist. Moreover, when connected to the entry of a building, the need for a network is avoided. This system generates electrical power independent of a network.
