What is a Self-Balancing Scooter

A Self-Balancing Scooter, sometimes known as a ‘Hoverboard Scooter’, is a 2 wheel automatic balancing rover which allows the user to move like they were on a segway while only using their feet to control the device. Borrowing most of its technology from the modern segway,  this scooter is a smaller, carry-on option for the average consumer.

The Self-Balancing Scooter has been climbing its way into consumer media with the popularization of the device by celebrities and YouTube personalities such as Kylie Jenner, Casey Neistat, and Tmartn. With each having their own unique massive audience it was a surefire conversation starter.

The Self-Balancing Scooter has been acquiring tremendous reviews from users so much so that some people have been buying in bulk so that they could get the best discount. While some scour the internet for the cheapest price. Some of the most praised and renowned balancing scooter is made by IO Hawk, MonoRover, and CHIC.

Though some can reach an amazing speed of 12 MPH, these scooters are made extremely durable. It accelerates by simply applying pressure with the front your feet. It carries two driver motors withing the wheels that can be controlled with both feet individually for easy turns, rotation, acceleration and smooth breaking. Weighing about 22 pounds this scooter is not light, however it is a sturdy enough to take a good amount of beating.

There have been some talk over the scooters that were sold by IO Hawk. Some people have noticed that the devices that were sold by the company cost ~$1,800 were the exact same as a copy by a Chinese company was selling for only ~$360. Some argue that they are a rip-off trying to make an absurd amount of profit while others defend the company saying that it is easier to deal with an american company as the middleman when it comes to redeeming their warranty rather than a Chinese Company.

For the most part the generic models that are being sold by the Chinese companies are of decent quality. Some popular YouTube personalities such as FouseyTube and Casey Neistat have personally praised some of the generic models because of the great quality and the savings.

Though some of these scooters are rather expensive, it is only in its early stages. As the technology advances the price of the device will ultimately drop. This will concurrently change the way that people get around and push us forward to a better future.



Reports in China: Progress or Greenwashing?

“Corporate Social Responsibility” Reports in China: Progress or Greenwashing?

Over the past decade, an increasing number of Chinese companies have begun to produce corporate social responsibility (CSR) reports. Whether that’s led to more sustainable business practices is an open question.

In 2006, State Grid was the only company in China to file a CSR report. In 2012, 1,722 Chinese companies filed CSR reports, according to a study by Syntao, a sustainability consultant. Indeed, almost a quarter of large state-owned enterprises in China filed CSR reports last year.

In theory, the purpose of CSR reports is to share information about a business’s social and environmental impact with the public. Ideally, the publication of such china credit report leads to enhanced awareness, better monitoring practices, and action to curb detrimental occurrences.

Yet while some Chinese companies have received international recognition for enhanced CSR reporting, it’s not clear the trend has translated broadly into more socially and environmentally sound policies. As Chris Marquis, an associate professor at Harvard Business School, and Yang Chen, an associate professor at Shanghai Maritime University, wrote on Dec. 5 in the online magazine Chinadialogue, “some of the same companies that were lauded for their reporting work were not necessarily following through with more responsible actions in the rest of their enterprises.”

Marquis and Yang pointed to several examples, including Baogang Group, a steel company in Inner Mongolia. The company “claims to have invested tens of millions of dollars a year in environmental protection and waste processing, and has also been recognised for its CSR and sustainability activities,” the researchers write. However, earlier this year pollution from Baogang’s facilities near the village of Dalahai was linked to “unusually high rates of cancer, along with high rates of osteoporosis and skin and respiratory diseases, and the radiation levels are ten times higher than in the surrounding countryside.” Obviously, not a sign of its commitment to principle.

At the very least, some Chinese authorities appear to have embraced the concept of corporate responsibility. In November, the Chinese Academy of Social Sciences released a blue book, or official report, on the state of CSR in China, which recommended improved reporting guidelines. Currently, the Shenzhen Stock Exchange offers training on data collection and corporate reporting methods. That makes smart business sense, as unsustainable practices may prove a future liability to growth. Even smog-choked China is looking for ways to clean up.

Buying an electric scooter? Check out this guide.

So…you wanna buy an electric scooter eh. You’ve come to the right place. You’re immediately going to see the increase in convenience and the decrease of transportation expenses. Not to mention having tons of fun.

Follow these simple tips to get the most out of your new investment, and see you on the streets of Beijing!

1. Buy for comfort
Wether this is going to be your main mode of transportation, or just something fun to use in the weekend, you’re going to want to use it more if it’s comfortable.

Check out the various body styles and frames to see which ones suit you the best. If you’re a shorter rider, than look for the Honda Ruckus style (left) of electric scooters, or maybe the mini turtle for the female riders. This will provide a lower seat position and a lower center of gravity to help shorter riders balance during stops.

Next up is seating position. Just like a motorcycle, there are many types of seating positions and handle bar positions. Wide bars, narrow bars, drag bars, etc. Find the position and style that works for you. Usually, the various body styles come with set bars, but they can be changed so they are more comfortable for you.

Most importantly, get out there and test-fit some of these body styles. Don’t worry about power, or battery configurations yet. Just test to see how comfortable it is for you. If it’s not comfortable, you’re not going to ride it.

2. Buy for distance
How far is your commute?
Where do you go in a typical day?
How many miles do you cover before you get to a recharge point?
Are you allowed to recharge a battery at your office?

Evaluate all the above questions and figure out how much distance you’ll need to cover before a recharge.
If you go a pretty signification distance, look for Lithium Ion or Lithium Polymer battery packs. They’re lighter and smaller, but more expensive.
If you need to keep costs down, double up on SLA (sealed lead acid) batteries, such as 48v, 60v or 72v, 30-40ah.
If you will recharge at work, make sure they’re removable and light, such as 2x 24v, 20ah battery packs (right), so you can bring them in one in each hand.

3. Finally, buy for power
This part is the easiest of them all. Just like car racing, power (speed) is proportional to how much money you want to put in. Same thing with China Segway.

If you have found an e-scooter style that you like and that fits you comfortably and have calculated that your commute is realistic when it comes to an e-scooter, then power is easy….buy the most power you can afford; you’ll thank yourself in 6 months’ time.

Keep in mind that these speeds are all at full charge, so you only get about 15 mins at this speed. On average expect speeds about 10% slower than the listed above for realistic daily riding.

Well, there you have it, a few tips on preparing to buy an electric bike or electric scooter. Please leave a comment if you think this guide has been helpful…第七个

GW to expand solar

The Office of Sustainability will purchase more solar panels and partner with engineering professors to build a small-scale wind turbine this year, as GW tries to reduce its dependence on coal power over the next decade.

The solar panels will heat campus water systems and capture rays for electricity, Director of the Office of Sustainability Meghan Chapple-Brown said. It will be the first time the University uses solar energy for electricity on a larger scale, after having used solar panels on three residence halls to heat the buildings’ water for the past two years.

While the office is still working out details, the move will put GW on track to reach its ambitious goal of slashing greenhouse gas emissions by 40 percent by 2025 and 80 percent by 2040.

The solar panels will be the newest added since GW first began collecting solar energy in 2011 with rooftop installations on Ivory Tower, 1959 E St. and Building JJ.

Those panels collect enough power to heat most of each building’s water use the year. In the last three years, the system saved a total of about 300 tons of carbon dioxide, said Shannon Ross, a coordinator in the sustainability office – which is equivalent to the energy use of 14 homes for one year.

The University’s Climate Action Plan, released three years ago, also calls for the campus to produce 10 percent of its own low-carbon energy technology by 2040.

The two renewable energy projects are part of a massive University-wide sustainability plan, which sets goals for GW to grow its own food, produce zero waste and eventually stop producing carbon altogether.

Going carbon-neutral is the most important step GW can take to become a more sustainable college – and to jump in national rankings of green colleges, said Avital Andrews, an environmental expert who is an editor for the Sierra Club’s magazine.

“Climate change is probably the most dire environmental issue that we face right now – not that water pollution and landfills aren’t a huge problem as well, but it’s what we’re most concerned about,” Andrews said. “We’d love to see as much solar as possible.”

And boosting GW’s sustainability score is a big priority for the University, Chapple-Brown said.

Five years ago, the Sierra Club named GW one of the nation’s least eco-friendly schools. That failing score came a year after University President Knapp arrived at GW with sustainability as one of his highest priorities.

This year, GW crept onto the list of the top 25 green schools, coming in at No. 23.

GW, though, lags behind competitor schools such as American University, which is on track to become carbon neutral in just seven years. In addition to converting solar power into electricity, AU has the largest solar-powered water heating system in the District. It also converts used cooking oil from its dining halls into electricity.

Andrews, who has studied colleges’ uses of renewable energy, said it can take years for schools to make broad changes in their energy consumption, but that process can be sped up if an administration fully buys into the plan.

“It seems like something that can happen quickly if schools put their mind to it, and especially if there’s a demand from students and alumni,” Andrews said. “They can make it happen quickly if they want to.”

The types of clean energy a school uses depends on its location and what resources it has available, Andrews said. The University of Washington, for example, which sits on a bay that opens into the Pacific Ocean, is almost entirely hydro-powered.

Solar panels are more suited to city life, especially in D.C., which sees lots of sunlight and heat almost daily, Andrews said. She noted that the White House recently added more solar panels to its roof.

As GW tries to use alternative sources of energy, it is also going through a multi-million dollar effort to upgrade the electric and heating systems in the University’s buildings. The project, dubbed the “eco-building program,” began last year and will reduce energy use in each upgraded building by 15 percent.

High-tech biometric security

IN A typical James Bond film, the suave hero deals with iris scans, facial recognition systems and voice authentication as common technological security measures, but such gadgetry is fast expanding beyond the realm of Hollywood’s imagination.

Marius Coetzee, MD of identity management company Ideco, says biometrics refers to the identification of humans by their physical characteristics or traits.

Arriving at Ideco’s offices in Pretoria is like walking onto the set of a spy movie. To enter, a visitor must submit a fingerprint to the guard on duty along with an identity number and contact details. Then a registered and verified employee must open the door, again using fingerprint technology. The time and date are logged, as is the name of the person who opened the door.

Mr Coetzee says the industry has made the biggest advances in fingerprint biometrics.

“It’s a key aspect of forensic application. At a crime scene, the first thing the police dust for are fingerprints. Most people have 10 fingers and it’s highly unlikely for any two people to have the same prints. If you remember the first time you took fingerprints, it was probably with dark ink on paper, but technology has advanced since then,” he says.

“Depending on how good the technology is, it cannot only capture and store your fingerprint in 1.8 seconds, but also verify whether that fingerprint belongs to you. Fingerprint biometrics is now a real-time application.”

Mark Paynter, a sales executive at Ideco, says the technology is evolving rapidly.

“We’ve seen in the movies where people are able to lift someone’s print from the scene and access information that’s not their own (by stealing someone’s identity), but that is going to become more difficult to do.”

He pulls out a small, glossy black box. “This is the finger-vein print scanner. Not only does it check your fingerprint, but it also captures your vein network and checks to see whether blood is circulating in that finger. Like all security, none of it is criminal proof, but no run-of-the-mill criminal could crack this kind of intense biometric technology.”

Biometrics technology is in different stages of development globally, but South African technology and compliance are at the forefront. The police, the South African National Defence Force and government departments such as home affairs all use state-of-the-art biometric technology. The quality of the equipment is measured against a global standard for biometrics set by the FBI in the US.

The Department of Home Affairs has in 2013 started rolling out new smart South African identity cards that use biometrics. According to Home Affairs Minister Naledi Pandor, laser engraving of personal details and photographs make the card difficult to forge or change. The smart card is expected to curb the use of fake or stolen identity documents.

The government’s technology meets the FBI standard, but according to industry sources, not all financial institutions in South Africa do, which would make their biometric evidence inadmissible in a court of law.

But are these high-tech systems within the reach of smaller businesses? Paul Hutton, CEO of voice biometrics company One Vault, says that as the technology improves, more companies are showing interest and the cost is declining.

“I used to work at a credit bureau and one of the major worries was always that our clients’ information wasn’t as secure as it could be,” he says. “Identity theft is becoming a scary phenomenon, increasingly in South Africa too. We work on a consumption model, which means there aren’t any large start-up costs. You pay for the technology as you use it.”

He adds: “Voice authenticating improves customer satisfaction and reduces costs and the probability of fraud. And this kind of biometric technology is the only one that can be used remotely.”

Mr Hutton says passwords used to access devices such as laptops and cellphones will soon be replaced by biometric controls. As ever more transactions are conducted online, companies are requiring significantly enhanced, multilevel authentication systems to combat fraud. There are also a range of processes — such as password resets — that require authentication but are time consuming and costly for companies and clients alike. These processes can be automated using remote third-level authentication at greatly reduced cost and with improved security.

In third-level authentication there are three ways of authenticating a person’s identity, in case of failure of one or two of the methods.

“Voice authentication is actually a technology that has come out of the military,” Mr Hutton says. “It’s not that easy to crack. If you record my voice and play it back to the machine, it won’t give you access to my data and information.

Objections to wind turbine at Gerahies

FASTNET Mussels Ltd has applied to Cork County Council for permission to erect a 20 kilowatt wind turbine and also to retain a reinforced concrete base for same at Gerahies, Bantry Bay but it has been met with over 20 objections.

The application was lodged on June 14th and one of those opposed to the development, who resides in the area on the northern side of the Sheep’s Head peninsula overlooking Bantry Bay, contacted The Southern Star last week and summarised the main points of concern among objectors as follows:

1) It is a designated scenic coastal area. Such areas should be protected from the ugliness of wind towers. Sheep’s Head Peninsula is enjoyed by locals, cyclists, walkers and those who come on a scenic drive.

2) It is a Special Area of Protection due to the presence of rare birds.

3) A wind turbine would produce noise pollution which would be intolerable for those living in close proximity.

4) The shadow flicker created by the movement of the blades would be intolerable for those living nearby, and it would be intrusive to all those who can see the turbine from the hill above, even from afar, possibly, from the Beara Peninsula.

5) The close proximity of the site conflicts with industry guidelines for location near farm land and settled residential communities.

6) An explanation is needed as to why an application for retention of the concrete based was required.

The objectors further stated that the rural character of Sheep’s Head Peninsula should be preserved because its beauty played an important part in the development of a robust tourist economy.

The person who contacted this newspaper (who was unaware of the 20 fee and therefore her letter of objection couldn’t be accepted on the last date for submissions) and an objector we spoke to said they and other objectors, who they were able to contact, declined to be named but added that the names of all objectors were to be seen in the planning file.

Our reporter called to the planning department at the ground floor of County Hall and viewed the planning file which confirmed the above mentioned concerns expressed in letters of objection and observation, each submitted at a cost of 20 up to the closing date of July 18th. The submissions, which range from a single page to 24, can also be viewed in at the council’s office in Skibbereen.

While some stated that in principle, they were in favour of renewable energy, they were strongly opposed to the location in question on the basis it would have a detrimental effect to the visual amenity of an area of outstanding beauty.

It was contended the sight of wind turbine could damage tourism and overall, impact on the quality life along a scenic route (Goat’s Path) in the award winning peninsula and Bantry Bay where 21 dwellings were within 1.5 kilometres of the proposed structure.

There was also a statutory observation on file from An Taisce – the National Trust for Ireland requesting a visual impact assessment be carried out due to its extremely exposed position on the coast. It also quotes from the 2009 Cork County Development Plan: ‘Areas which, because of high landscape sensitivity, are considered generally to be unsuitable for wind energy projects.

While there may be a small number of locations within these areas with limited potential for small scale wind projects, their contribution to any significant reduction in greenhouse gas emissions would be negligible.

Except on a small scale and at particularly suitable locations, wind projects would normally be discourages in these areas’

The letter, signed on behalf of An Taisce’s Built and Environment Officer Ian Lumley, added: ‘Given that there are scenic routes along this site, as designated in the county development plan, it is not considered that this location, regardless of scale, is an inappropriate location’.

Wind Storm

The tiny community of King Island off the north-west tip of Tasmania has voted to push ahead with plans for the country’s biggest ever wind farm.

A community ballot has revealed 59 per cent support for Hydro Tasmania to conduct a multimillion-dollar feasibility study into a 200 turbine wind farm.

It’s a decision that’s been made against the backdrop of a dwindling population, fewer jobs and closing businesses.

The massive wind farm would generate about 2,400 gigawatt hours of electricity a year, to be sent across Bass Strait by a high voltage underwater cable to the national electricity market.

Hydro Tasmania says it could produce enough electricity to power a quarter of a million households, a huge chunk of the nation’s renewable energy targets.

But as Fiona Breen found out, the issue has divided the community. Friends and even families are no longer talking.

FIONA BREEN, REPORTER: On a wintry Saturday, a sporting battle pitches mate against mate, colleague against colleague and even family against family.

For 1,500 King Islanders, the three-team footy competition stirs sporting passion. Today, it’s Grassy versus North. It’s a tough, close match.

Off the field, another battle has been simmering. Like football, passions have come to the surface.

VOX POP: I’m against. Don’t want any wind farms here to – they’re just ugly, horrible things.

VOX POP II: I think the wind farms are a great idea for the island, even if it just goes to feasibility.

VOX POP III: I don’t want to look at wind towers really, but if it’s going to help out the island, well, we need it.

FIONA BREEN: King Island is in the Roaring 40s. Its rugged coastline is a graveyard of shipwrecks driven ashore by the winds. Calm days are rare and the wind blows at an average speed of 32 kilometres per hour. It’s that consistent wind that Hydro Tasmania wants to harness, using 200 turbines costing $2 billion. The company has spent six months taking the proposal to the local community.

ANDREW CATCHPOLE, HYDRO TASMANIA: We’re taking a very different approach in coming to King Island to have this conversation before doing a feasibility study, a different approach to that taken previously and elsewhere for these kinds of projects.

That is very deliberate to try and understand, and I suppose to demonstrate, that not all wind farm developments are the same. They don’t have to be the same. And so we hope you would see that as a sign of our commitment to continue to work with you to ensure that if this goes ahead that there is an optimum outcome for the community.

FIONA BREEN: The community ballot has now been counted and the result was tight. Nearly 59 per cent supported taking the 200 turbine wind farm proposal to the next stage, but there was only 10 or 11 votes in it.

Hydro Tasmania had always said it needed at least 60 per cent community support for it to go ahead. At an emergency board meeting this week, the company decided it was close enough.

ANDREW CATCHPOLE: Well certainly we’re aware that there are different views in the community and we want to work with all sections of the community going forward about their concerns, as we’ve indicated. But we do feel that the survey result of 59 per cent is a very strong indication of community support to go forward to a feasibility study.
