'Green' message at root of eco festival

Carolyn Khew The Straits Times AsiaOne 24 Apr 15;

A festival celebrating all things eco-friendly will walk the talk.

EarthFest will feature more than 50 environment-friendly businesses and organisations. It will have a food fair, a farmer's market, live music and games.

To drive home the "green" message, vendors who produce less waste will pay lower fees for participating in the festival, scheduled to take place at the Marina Barrage on Sept 26.

Leftover organic waste, such as food waste, will be composted. The use of plastic bags will be banned.

Festival director Michael Broadhead said the event had been designed to reduce waste and energy usage. Attention had also been paid to the types of businesses allowed to participate and the products to be sold.

The organiser will come up with strategies to stop waste from being created, or to recycle or dispose of it responsibly, said Mr Broadhead, a teacher at an international school.

"We are the first festival in Singapore that will compost its organic waste, and no products can contain palm oil unless it is certified sustainable," he said.

Brownice, which sells ice cream made from brown rice milk, is one of the businesses taking part in the event, where it will use wooden spoons instead of plastic ones.

Ms Sophia Goh, 25, a private tutor, said she was keen on attending the festival: "I think it will be well-received because environmental awareness is growing here."

Free tickets to the festival can be reserved at http://earthfestsingapore.com

Made in Singapore: Fast-charging electric taxi launched

Channel NewsAsia 24 Apr 15;

SINGAPORE: An electrical car, said to be the first to be designed, developed and manufactured locally, was officially launched on Friday (Apr 24).

The car, named EVA, was built by TUM CREATE (Campus for Research Excellence And Technological Enterprise) - a collaboration between Nanyang Technological University (NTU) and Technische Universit√§t M√ľnchen (TUM), according to the press release.

The new carbon fibre-structured vehicle, purposed to function as a taxi, will provide Singaporeans a futuristic alternative to the regular fuel-powered taxis. EVA was developed with user studies and observational analysis based on how Singaporean commuters utilised taxi services.

It has a maximum speed of 111 km/h and a battery system that allows it to cover up to 200km with 15 minutes of charge time, according to the developers.

"The challenges surrounding fast charging include the high electricity currents needed and the heat that is consequently generated in the battery pack during the recharging process," the press release stated. "Our engineers have designed an innovative concept for more effective thermal management of the battery cells that targets to extend the pack's lifespan."

NTU President Professor Bertil Andersson also highlighted another achievement: "EVA is the first car ever designed,developed, and manufactured locally. While Singapore is not an automotive manufacturing country, the nation's economy will definitely benefit in the long run through technology transfer."

TUM CREATE CEO Maria-Elisabeth Michel-Beyerle added that many of the technologies researched and used in EVA, such as the fast-charging battery system, had yielded innovations beneficial to the automotive industry.

"Through EVA, this partnership between TUM and NTU has led to the development of several technological innovations which have caught the attention of the automotive industry. We are also now in discussions with some companies who are interested to commercialise our innovations," the CEO said.

Additionally, over the next four years, NTU will turn into a national test-bed for smart mobility solutions such as Vehicle-to-Everything (V2X) technology, which seeks to equip cars with devices capable of interacting with traffic infrastructure and other vehicles, according to the press release.

Singapore’s first electric taxi ‘now road-ready’
XUE JIANYUE Today Online 24 Apr 15;

SINGAPORE — The prospect of locally-designed electric-powered cabs plying roads here is a step closer to realisation, with talks started with automobile manufacturers on mass production of the technologies in the vehicle.

First unveiled as a prototype without engines, batteries and air-conditioning at the Tokyo Motor Show in 2013, EVA, Singapore’s first electric taxi — designed and created by researchers from Nanyang Technological University and Germany’s Technische Universitat Munchen (TUM) — is now road-ready.

Speaking at a press conference today (April 24), Professor Markus Lienkamp, scientific advisor director at the TUM-CREATE research centre, said talks are ongoing with industry players to bring their technological designs to mass market.

Touted as the first electric taxi suited for the tropics, EVA has seats designed to draw air and moisture away from passengers’ bodies, and reducing the need for air-conditioning. Overhead air-conditioning outlets target upper bodies of passengers and drivers to reduce the need to cool the entire cabin, while a lightweight carbon fibre is used for the body as a fuel-saving feature.

Professor Lam Khin Yong, NTU’s chief of staff and vice-president for research, who is one of the designers involved, said these features can be adopted by vehicles to reduce their carbon footprint. “Due to the hot and humid weather in the tropics, a significant amount of energy is consumed by the air-conditioning system in automobiles,” he said.

The more than 28,000 taxis here make up less than 3 per cent of Singapore’s vehicle population but account for 15 per cent of the total distance covered by all vehicles here, studies done by researchers behind EVA show.

Two barriers to mass-adoption of electric taxis are their high cost and insufficient fast-charging stations, said electric vehicle researchers.

Prof Lienkamp said mass production would push the prices of electric cars down, making it more attractive for widespread adoption “because there is no reason to buy the then-more expensive combustion engine”.

Although there are more than 70 charging stations in Singapore, Prof Lienkamp said only “three to four” are fast-charging, which allows the taxi to charge enough power in 15 minutes to run 200km.

Singapore’s size makes it viable to build more such stations, said Professor Thomas Hofmann, TUM vice-president for research and innovation.

“The size of the country, it is quite small. It would make sense to build up a dense network of these charging stations. If you go to the United States, for example, it is much more complicated,” he said.
