Tower Net Lima in the Philippines

Often when building a skyscraper neglect factors relating to the site is located where the project, especially those relating to the environment and until the subsequent implementation of renewable energy taking advantage of its structure, therefore we highlight the emergence of what will describe below.

It is a complex of three towers which will represent the complex Net Metropolis 5th Avenue the capital of the Philippines (Manila), in the commercial district of fort Bonifacio, and that it will serve as headquarters to large companies in the Asian State counting on a surface covered 1.550.000 square metres, surrounded by some parks full of trees and plants of all kinds.

The first one has been built, under the name of Tower Net Lima, and carries a design planned to be adapted and sustainable structure for providing a great help to the use of renewable energy, also joined a remarkable decrease in power consumption.

We highlight the existence of wind turbines which will enable supply to the Tower, coupled with an innovative system that uses a solar filter special made in aluminium, placed on its periphery, which repels heat (designed to reduce consumption electricity generated by the innumerable installation of air-conditioning, something common in offices)

This joined other engineering looking to take advantage of everything that eventually is discarded, as for example the water from the Air conditioner, which would be stored in a special containers for cleaning and irrigation of the Park.

Generates2011 Energy and environment international fair organized by IFEMA, will be held from 11 to 13 May 2011 in FERIA of MADRID. IDAE Institute for diversification and energy saving) there will be an area specially dedicated to the sector of electric mobility, whose objective will be to disseminate the Plan of action of the vehicle electric 2010-2012 (Plan movele).

Zone MOVELE you will have a physical space itself GENERATES 2011. There the IDAE meet all kinds of related companies with the electric mobility: vehicle manufacturers, companies installing recharging, energy companies and public and private institutions.

It's definitely a highly recommendable event for those who closely follow latest advances in the field of electric vehicles to access new models and technologies first hand.

Curious semi-submarino boat electrical

That today we bring you - more than anything else - is a curiosity in the field of electric vehicles , which is mostly of a somewhat eccentric luxury item (which does not remove that would be very interesting to upload one them!). It is a compact semi submarine that uses a fully electric motor have dubbed as "Ego". The company that produces is called Raonhaje, and has released two different models "Ego you (Deluxe Edition) and Ego is (standard edition), both with capacity for 2 passengers."

Consists of a surface type pot with cover to enjoy the landscape and the navigation and - below-cabin underwater with large Windows that allow observing fish, with all its magnificence as if we were practicing diving or snorquel.

Boat semi-submarino EGO has a battery that allows 8 hours of use in cruising speed, or 4 at maximum speed, while every recharge takes between 6 and 9 hours.

I hydrogen by mimicking photosynthesis

As many know, photosynthesis is one of the activities any sort of vegetable Kingdom can generate their own food, i.e. energy, something that if took it to the demands of electric power, is precisely what is being sought from the earliest times.

Focusing on this concept, it has been announced that a new technology that plan to use a very similar to the photosynthesis system to create electricity using hydrogen is currently in full development.

As many know, one of the ways to obtain this raw is "breaking" the water molecule, although also it may be subjected to other processes to generate new hydrocarbon resembling a fossil, fuel behaviour although of course, should participation oxygen in this reaction.

In plants, acts also as an oxidizing agent, but it is quickly released in breathing, absorbing carbon dioxide, which would have to work for increased performance (for the moment, the structure of the hydrogen cell degrades)

As if this out, this would be combined also with the use of solar energy, applying directly using a blue light technology, creating a highly efficient energy conversion system.

At the moment it's all in development and is no more than a project, though it is advancing by leaps and expected results are too optimistic.

Graphene: Solar Cells of the Future?

A southern California University team has come up with what could be the alternative new breed of economical and flexible solar cells. For some decades now, organic photovoltaic cells (OPV) have been acclaimed as the new solar cell prototypes and extolled for their light weight, flexible substrates, low cost and easy manufacturability. Research is now being done on them.

Features of OPV cell:
The most unique aspect of the OPV cell devise is the transparent conductive electrode. This allows the light to react with the active materials inside and create the electricity. Now graphene/polymer sheets are used to create thick arrays of flexible OPV cells and they are used to convert solar radiation into electricity providing cheap solar power.

New OPV design:
Now a research team under the guidance of Chongwu Zhou, Professor of Electrical Engineering, USC Viterbi School of Engineering has put forward the theory that the graphene – in its form as atom-thick carbon atom sheets and then attached to very flexible polymer sheets with thermo-plastic layer protection will be incorporated into the OPV cells. By chemical vapour deposition, quality graphene can now be produced in sufficient quantities also.

Differences between silicon cells and graphene OPV cells:
The traditional silicon solar cells are more efficient as 14 watts of power will be generated from 1000 watts of sunlight where as only 1.3 watts of power can be generated from a graphene OPV cell. But these OPV cells more than compensate by having more advantages like physical flexibility and costing less.

More economical in the long run:
According to Gomez De Arco, a team member, it may be one day possible to run printing presses with these economically priced OPVs covering extensive areas very much like printing newspapers. In Gomez’ words – “They could be hung as curtains in homes or even made into fabric and be worn as power generating clothing…. imagine people powering their cellular phone or music/video device while jogging in the sun.”

Advantages of OPVs:
The flexibility of OPVs gives these cells additional advantage by being operational after repeated bending unlike the Indium-Tin-Oxide cells. Low cost, conductivity, stability, electrode/organic film compatibility, and easy availability along with flexibility give graphene OPV cell a decidedly added advantage over other solar cells.

The team:
The USC team, consisting of Chongwu Zhou, Cody W. Schlenker, Koungmin Rye, Mark E. Thompson, Yi Zhang and Gomez De Arco published a paper about their research in ACS Nano journal and are very much excited about the future potential advantages and uses that are possible with the OPV grapehne cells.

PETE Process Promises Successful Technology Fusion

A new joint venture research work at Stanford and SLAC National Accelerator Laboratory, supported by Department of Energy and DARPA has come up with a new solar energy conversion process that can potentially double the efficiency of solar cells. Stanford engineers have discovered this new and totally different process to harvest energy from sun.

Way to make the cells more efficient:
The best way to increase the efficiency of the solar cells is to somehow harvest the wasted heat energy and to keep up and utilize the high temperatures which are reached during conversion. Utilizing the existing technology along with utilizing both the photovoltaic and thermal conversion techniques is what is needed.

Breakthrough process:
In the new process, the semiconducting material was coated with a thin layer of caesium which allowed the material to use both the light and heat of sun to generate electricity. Though this is not actually standardized photovoltaic mechanism happening, this is a photovoltaic-like response happening best at very high temperatures. The new process is called Photon enhanced thermionic emission (PETE).

Conceptual breakthrough:
Nick Melosh, Assistant Professor of Material Science & Engineering, leading the research group says, “This is really a conceptual breakthrough, a new energy conversion process, not just a new material or a slightly different tweak.” The new process is called ‘photon enhanced thermionic emission’ (PETE). This process is expected to reduce solar energy production cost competitively with oil.

Weakness harnessed as strength:
What is the weak point with most silicon cells – losing efficiency in higher temperatures – is the strong point of PETE process as the devices working with PETE process works best at temperatures as high as 800 degree Celsius. The PETE device utilizes the light and high temperatures produced are usable and dumped in the thermal conversion process.

Peaking efficiency:
PETE process has the potential to almost triple the existing system efficiency as demonstrated in solar farms in Mojave Desert in Southern California. Melosh says, “PETE process has two really big benefits in energy production over normal technology.”

Affordable process:
The tam claims that PETE process needs economical and easily available materials only – making thus the power harvested via this process very affordable. The conversion into PETE process is also relatively inexpensive as they are being designed to be bolted to present structures.

Research team goal:
The research team published their paper in ‘Nature Materials‘ after demonstrating the process successfully. The team is experimenting on various semiconductors like gallium nitride and gallium arsenide and other such materials. Even a 10 % boost to the existing solar efficiency is a 50% overall hike and very welcome for solar cell power generation.

Want to build an EV that gets the equivalent of over 2,000 mpg? Then build a e-bike.

You can check here: http://www.evsroll.com/DIY_Electric_Bike.html

Our DIY e-bikes hold about 1/2 Kilowatt-hour worth of energy. One gallon of gas has about 36 Kilowatt-hours. There are 128 ounces of fluid gas in a gallon.

So, 128 ounces gasoline per gallon / 36kWh = 3.6 ounces gasoline per kWh energy

And, 3.6 oz x 1/2 - 1.8 oz gas equivalent per 1/2 kwh = 1.8 oz gas equiv per charge up

The e-bikes will go around 30 miles per charge.

So, 128 ounces per gal gas energy / 1.8 ounces gas equiv per charge = 71 charges per gallon.

71 charges per gallon x 30 mpg = 2,133 miles per gallon

We can do this every day for 1,200-1,500 charge cycles

Check out the bikes here: http://www.evsroll.com/DIY_Electric_Bike.html

Hike, bike, ride an e-bike, drive an EV
