Recycled Concrete Sound Barriers
Road traffic is the biggest source of noise pollution in the UK . The noise generated by traffic on urban motorways can be disturbing for the occupants of dwellings along the boundaries of the road reserve. Currently, in urban areas, reflective solid noise barriers or special absorptive barriers are used to reduce the problem.

The reflective barriers, which are the cheaper approach to the problem, are typically made of concrete or timber. These constitute the major proportion of the installed barriers. The disadvantage of such barriers is that sound waves can be reflected over the top of the barrier exacerbating the sound nuisance for dwellings on the uphill side of the motorway. Another ...

Renewable Phenolic Compounds - Another Product of EnerSysNet's Mobile Energy Conversion Systems

Background

The wood products industry always manages waste and cost with an eye towards expanded profitability. For example, residual sawdust and chips in sawmill operations are bonded with wood adhesives containing phenol formaldehyde (PF) resin to produce engineered wood products such as particle board and Oriented Strand Board (OSB).

However, there is still waste – crowns and limbs at the harvest site and bark at the processing mill – that are usually burnt or buried in a landfill. Instead of burning, what if the waste could be turned into a more environmentally-friendly adhesive which costs less and potentially increases sales for the adhesive manufacturer?

A system for generating electricity in the offshore oil and gas industry comprises a wind turbine that can easily be moved along with a drilling rig or marine platform. The system provides a renewable and alternative to generating electricity, in the form of wind, and addresses portability demands by industry without using petroleum product to operate offshore. A platform supports the turbine and is held in safe proximity to the offshore platform by an anchoring element in the form of a buoy or seafloor tether. An electrical communication element interfaces between the turbine and the offshore platform.

While operating offshore, electricity is the foundation of all oil and gas operations. These operations run on diesel generators. Having diesel fuel ...

Those who have ever experienced a power outage understand the major headaches associated with losing electricity; figuring out how to keep food from spoiling, how to get water, plumbing, lighting, and heating & cooling to name a few. Some of us may have sworn to never have to experience that again, and have investigated a backup generator or battery system only to find them extremely expensive. What if there was a way to own an energy system that serves as a battery backup, reduces utility bills when electricity is available, and has the option to take your home completely off of the grid affordably? This is going to be possible in the near future with the development of Home ...

Studies at UC-Davis in 2007 have demonstrated that parasitic infestation(s) are a contributing factor in the onset of ‘Colony Collapse Disorder’ in honeybee populations, natiowide. According to the USDA, domestic honey production is off by 16% for the year 2012. CCD and recalcitrant infestations by the varroa mite (V.destructor) have contributed to this decreased production and has negatively impacted crop pollination/production, in general.

Our team has developed a new delivery system comprising 100% natural low-toxicity components, called, “L-Tip,” that has been shown to be effective in treatment of colonies where V. destructor is present. Preliminary field studies indicate effectiveness in treatment of Varroatosis and infestations by the Parasitic Phorid Fly Apocephalus borealis as well. Ongoing studies leading to Chapter ...

Known Problem:
Clean water is becoming a scarcer commodity, even near large bodies of water. Desalinization processes are expense to implement and very expensive to maintain. Scaling current designs is difficult.

Solution:
Using hydrogen fuel cell technology, we can develop and implement a very efficient design providing ease of deployment, ease of maintenance, and great scalability.

Design:
The source water could be the ocean. By using a process such as electrolysis the overall quality of the water is not of importance, as contrasted with PEM or many other process. By flowing much more water than needed through the electrolysis process and recirculating excess back to the source, the overall concentrations and condition of the ...

It is an innovative sea wave energy converter.

Although there are many systems for converting motion of the waves, this device is innovative because the particular mechanism adopted allows the conversion into electrical energy of the waves in any direction. The machine is comparable to a buoy immersion is environmentally friendly and easy to build. Can be modulated by merging multiple buoys in a row.

It has no need to be anchored to the seabed and can therefore be used in any situation in depth. It can be used either in seas and lakes.

The overall dimensions are reduced and each buoy is capable of producing 10 kW of electric power consistent with the motion of the ...

Self Irrigation container ( SIC-A)
Water is life. As we all know, all ancient cultures rose near water resources. They started agriculture, building dams and water reservoirs. Big reservoirs and dams built on rivers, not where there was little rainfall and flat zones. As civilizations develop and upgrade, that means more water consumption, for domestic and agricultural use. The world population is now over seven billion. All studies nowadays show that there are shortages in fresh water. The problem will be more clear in the next two decades. And some expect wars because of water shortages.

The fresh water main resources are rain and snow. The plants benefits are not more than 5% from the rain water; 85% of the ...

Wave energy extraction is complex and many device designs have been proposed. All types of sea waves electricity stations are expensive.

This device is simple and can be made by every handy man. The device is suitable for yachts or ocean research vessels. Main part is permanent magnet alternator (Fig. 1), pendulum is attached to rotor shaft, so the rotor (1) is not spinning, only moving right and left in sea wave rhythm. Movement is relatively slow, so number of poles of the alternator must be high. Magnetic flux in stator (2) is changing and in its coils electromotive force is generated. Alternator output voltage and as well as frequency is not stable because movement of the pendulum depends ...

Renewable energy developers face many challenges today. Three main challenges are: (1) no power grid in the vicinity, (2) no willing utility to buy that energy, (3) prohibitive stabilization costs of unstable renewable energy. The world's number of personal computers is expected to reach 2 billion by 2014 and 100's of millions of mobile computing devices are already in use, with the latter number expected to explode in the future. However, the energy requirement of these computers is largely unaddressed. Today, computer users just plug their computers into the wall sockets to charge their computers. An opportunity exists to find the nexus between the energy requirement for this growing number of computers and the challenges facing the renewable energy ...
