HYDRATION SYSTEM

August 23, 2011

04-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

Is it possible to drink too much water during ride without stop the vehicle?

Adequate hydration is as important as calorie replacement to an athlete’s performance, yet dehydration continues to be a condition many experience. This is especially true in cycling where evaporative losses are significant and can go unnoticed. Sweat production and losses through breathing can exceed 2 quarts per hour. To maximize your performance pre-hydration is important, and it is essential that fluid replacement begin early and continue throughout a ride.

Approximately 75% of the energy your body produces is converted to heat rather than being delivered to your muscles to power your pedal stroke. Keeping your body cool and re-hydrated during exertion will result in greater efficiency, higher power output, extended endurance, and a quicker, more thorough recovery. Say good-bye to the Wet Spot!


Individual fluid and electrolyte needs are widely variable during physical exercise due to differences in metabolic rate, body mass and size, environmental conditions (e.g. temperature, humidity, wind, solar load, clothing worn), heat acclimatization status, physical fitness, activity duration, and genetic variability. Sweat rates can vary from 0.5L/hr to more than 3 L/hr. Similarly, sodium concentration may vary from less than 460 mg/L to more than 1840 mg/L

03-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

Technology:

Why use a perfectly good water bottle on your bike when you could use a complex, expensive and awkward to use “hydration system” instead? That’s the promise of the VelEau Bicycle Mounted Hydration System.

01-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

The VelEau comes in several parts. First, there’s a saddlebag which holds 42 ounces (1.4 liters) of water. Then there’s a tube through which you drink, much like those found on CamelBak water bags. This runs from under the seat, along the top-tube to the handlebars, where it is secured to a retracting cord on the stem. This cord pulls the mouthpiece back into place when you’re done drinking, where it is secured by magnets.

02-The Future Of Bicycling Hydration, Bicycle Mounted Hydration System, Hydration System Mounts On The Bicycle Rear

If that seems like it’s complex, unnecessarily heavy and annoying to use, that’s because it probably is. However, there is at least a compartment to carry a multi tool in the same bag, which adds some utility.

MANUAL CHARGING CONTROL

01-wind up battery-crank up battery-battery storage technology-hand powered spinning re-charger battery

The Wind up battery is the endless independent source of power. It is the only tool you will need to charge your mobile phone batteries, notebook batteries, GPS or any other modern gadget which is in this information-packed world essential life companion. The use of wind up battery charger is easy and being that it is totally portable and independent power supply, it is a valuable part of accessory of every trekker’s, backpacker’s, traveler’s adventures journey. It is also an essential back up power supply for any critical emergency events when there is no power supply available nearby.


How does it work?

01-wind up battery- operation-working-twisting clockwise or anticlockwise makes charging

The wind up battery mechanism uses internal generator, which is usually hand-powered by spinning the handle on the device. The hand motion, in which AC alternator is driven by a crank converts human mechanical energy and generates the electrical power, by spinning magnets past a coil of wire, which is stored in battery. To charge the device, utilizing the wind up mechanism the hand crank needs to be pulled out of the folded position, and spun in clockwise/counterclockwise direction. After some time of cranking, when the device is charged the handle is folded into position and the device is available to use.

There are also foot powered wind up battery devices, which generate power and self charge by human energy through step action. These are able to jump-start a boat or automobile battery, and power a wide array of instruments and accessories and present a valuable and versatile tool for power supply.

The Devices using wind up mechanism

There are several devices on market which utilize the wind up mechanism. It can be used as a wind up battery charger, wind up flashlight, wind up radio, wind up clock, mp3 player, or a larger electricity supply unit. Usually there are hand cranks folded into the devices, which can be pulled out when needed. The wind up devices are a great way to promote environmentally clean green energy source as the power is derived through windup mechanism which efficiently harvests the human energy and converts it to electricity.

If you are an environmentally conscious consumer who likes to travel and have a power charger available for his electric devices and an emergency power supply then the wind up battery is the device to look for.

PRODUCE ELECTRICITY FROM SOLAR HEAT

August 22, 2011

01-solar thermal power conversion-beam radiation-direct normal irradiation-Solar-Power-in-Florida-turning solar heat into electricity

The principles of solar thermal power conversion have been known for more than a century; its commercial scale-up and exploitation, however, has only taken place since the mid 1980s. With these first large-scale 30-80 MW parabolic trough power stations, built in the California Mojave desert, the technology has impressively demonstrated its technological and economic promise. With few adverse environmental impacts and a massive resource, the sun, it offers an opportunity to the countries in the sun belt of the world comparable to that currently being offered by offshore wind farms to European and other nations with the windiest shorelines.

01-direct radiation-solar radiation-electromagnetic radiation-solar collectors-insolation

Solar thermal power can only use direct sunlight, called ‘beam radiation’ or Direct Normal Irradiation (DNI), i.e. that fraction of sunlight which is not deviated by clouds, fumes or dust in the atmosphere and that reaches the earth’s surface in parallel beams for concentration. Hence, it must be sited in regions with high direct solar radiation. Suitable sites should receive at least 2,000 kilowatt hours (kWh) of sunlight radiation per m2annually, whilst best site locations receive more than 2,800 kWh/m2/year.

01-solar panels-solar power energy-solar power system-diagram_solar_power-produce electricity from solar energy example

In many regions of the world, one square kilometer of land is enough to generate as much as 100-130 Giga watt hours (GWh) of solar electricity per year using solar thermal technology. This is equivalent to the annual production of a 50 MW conventional coal- or gas-fired mid-load power plants. Over the total life cycle of a solar thermal power system, its output would be equivalent to the energy contained in more than    5 million barrels of oil2).

TURNING SOLAR HEAT INTO ELECTRICITY

01-illustration_trough_collector_from_sunlight-solar collector assembly-parabolic trough solar collector

Producing electricity from the energy in the sun’s rays is a straightforward process: direct solar radiation can be concentrated and collected by a range of Concentrating Solar Power (CSP) technologies to provide medium- to high temperature heat.


01-concentrating solar power plants-CSP Technologies-Concentrating solar power technologies-direct solar radiation process-parabolic solar trough collectors

This heat is then used to operate a conventional power cycle, for example through a steam turbine or a Stirling engine. Solar heat collected during the day can also be stored in liquid or solid media such as molten salts, ceramics, concrete or, in the future, phase-changing salt mixtures. At night, it can be extracted from the storage medium thereby continuing turbine operation.
