Longitudinally unzipped carbon nanotubes for supercapacitors
In this study, longitudinally unzipped carbon nanotubes (L–UCNTs) prepared from multiwalled carbon nanotubes and their electrochemical properties for supercapacitors were investigated after thermal treatment. Thermally treated L–UCNTs (RL–UCNTs) had a specific surface area of 288 m²/g and mesoporous pore characteristics. Also, RL–UCNTs had numerous oxygen heteroatoms, which affected ...

How will this new development in batteries make wind and solar power more completive?
The trend is changing in obtaining energy from conventional sources to obtaining energy from solar and wind power units. The change in trend is due to this energy is considerably cheaper than the energy obtained from several other methods. Earlier an expensive metal was used over in the chargeable batteries for solar and wind units. Mostly these units contain platinum and other very expensive ...

Are Solar Powered Drones The Way Forward?
Just recently, Titan Aerospace released a video of a solar-powered drone that will be put through rigorous testing later on this year. Named the Solara 50, the drone can theoretically fly without having to land constantly to fuel up. The implications are numerous – from the fact that a drone that does not need to land can be used in the name of science, to the possibility that it might be ...

Simulation study of dimensional effect on bipolar resistive random access memory
The dependency of the RRAM device electrical parameters such as set voltage, reset current and resistance on the RRAM cell dimensional scalability is investigated with Monte Carlo simulation to optimise the power consumption of bipolar RRAM. It is found in the simulation that the switching process in bipolar RRAM is related to the cell dimension in the region of 10 nm to 100 nm in terms of its ...

Competition in Wind Power, Outcomes for the future
Without a doubt, wind power is taking the lead as not only a renewable energy with a much lessened environmental impact, but it is also edging out the competition from fossil fuels with the distinct ability to lessen the impact on the wallet. Fossil fuel consumption, headed by traditional fuel sources such as oil and natural gas, are falling to the way side as having a significant difference in ...

Decentralised operation of residential energy resources in the smart grid
In the future smart grid, improvement of power system economic cost effectiveness by suitable integration of distributed energy resources (DERs) is a critical challenge. An agent–based framework is proposed in this paper for developing suitable control strategies for operations of four different types of residential–level DERs, which are storage devices, photo voltaic systems, and two ...

Sure Green Island, Palawan, Phillipines - Case Study
Our PP20 Power Pallet was Installed in Green Island, a small village island located about 14 kilometers off the coast of Roxas, Palawan, in the Philippines. The project is being developed by Solutions Using Renewable Energy (SURE) who are building a microgrid system tying a 2.5 kW solar array and a 5 kW wind turbine to our 20 kW Power Pallet. This grid is supplying power not only provide light ...

Simultaneous carbon and nitrogen removal using a litre-scale upflow microbial fuel cell
A 10 L upflow microbial fuel cell (UMFC) was constructed for simultaneous carbon and nitrogen removal. During the 6-month operation, the UMFC constantly removed carbon and nitrogen, and then generated electricity with synthetic wastewater as substrate. At 5.0 mg L−1 dissolved oxygen, 100 Ω external resistance, and pH 6.5, the maximum power density (Pmax) and nitrification rate for ...

Comparison of EMI generated by fly–back converter with other single switch isolated converters
Fly–back converters are popular in low power ranges because of their simplicity and low component count, but they generate lot of Intrinsic Differential Mode (IDM) noise. IDM noise generated by most of the other single switch converters is comparatively less than that of fly–back. Particularly, IDM noise in converters such as SEPIC and Cuk are negligibly small. They have a potential to compete ...

Water Line Project - Holloway Bar Placer Mine (archived)
One of the biggest problems with living in a remote area is access to facilities that we take for granted. If you want to watch TV, you need both a satellite dish and power to run the dish and TV. If you want to have a shower, you'll need some way to pump the water as well as heat it. If you want to cook some ham and eggs, you'll need to find a way to keep the food cool, or it'll turn into Dr. ...

Performance of microbial fuel cells on removal of metronidazole
The microbial fuel cells (MFCs) are the focus of extensive investigation as one of the promising technologies for renewable energy generation and wastewater treatment. Two-chambered MFCs were designed to investigate the removal of metronidazole and to quantify the effect of antibiotic on the efficacy of energy generation. Using 1,000 mg glucose L−1 containing different concentrations of ...

Flywheel energy storage control for use with intermittent energy source
Systems used to extract renewable energy often are subject to suboptimal working conditions due to the intermittent nature of most renewable energy sources. The flywheel energy storage system suggested in this paper utilises an electronic clutch that engages and disengages the generator from the flywheel of the renewable energy system in an attempt to prevent the generator rotor from coming to a ...
