Greater range for electric vehicles: Two-in-one motor

September 30th, 2014
Scientists have invented a 2-in-1 electric motor which increases the range of electric vehicles. This innovative engine integrates the traditional electric motor with the air-con compressor, typically two separate units. This novel, space-saving design allows the use of bigger batteries, which can increase the range of electric vehicles by an additional 15 to 20 per cent.

Hong Kong tycoon in ambitious green energy drive

September 30th, 2014

Zheng Jianming, chairman and founder of Ltd., is considering a public listing for the holding company he created to manage what may be the world’s biggest collection of solar-manufacturing businesses.

Hong Kong-bases Zheng is convinced that clean energy can power every aspect of life and has already accumulated $20bn in Chinese solar manufacturing assets.

Speaking on Monday at the Next Generation Solar PV Finance event in New York, he discussed his strategy to advance the building of green cities worldwide, in part by creating the first-ever, vertically integrated clean energy supply chain.

The listing indicates his desire to expand into other green energy technologies.

Asia Pacific Resources Development Investment is also investing in battery technology, electric cars, geothermal systems and even units that use seawater to store electricity. The goal is to supply clean energy for almost every aspect of daily life, “from the power source to heating and cooling, lighting and vehicles,” Zheng said.

“If a city were to implement all of these technologies it would basically be low-carbon,” he said in an interview in New York. “My vision for this company isn’t just for China. I want to create a global company.”

In New York Zheng, granting a rare public speech, said his approach was to identify the world's best complementary clean technology companies to create entire supply chains across multiple verticals and to produce integrated solutions on a massive scale.

"Clean energy brings a much brighter future for mankind and mother earth,” he said. “Investors and entrepreneurs should be focused on this sector. By investing in companies that together bring total solutions, we enable cities to transform the ways they grow and consume resources and we can ensure a high quality of life for us and for future generations."

Among Cheng’s ambitious goals is the deployment of more than 50 GW of installed clean energy capacity in the next 10 years -- enough to power over 37 million homes.

In-flight sensor tests a step toward structural health monitoring for safer flights

September 29th, 2014
A flight test program is underway on nine commercial aircraft flying regular routes that are carrying sensors to monitor their structural health, alongside their routine maintenance. The flight tests are part of a Federal Aviation Administration certification process that will make the sensors widely available to U.S. airlines.

Siemens chief: Economies to rely on fossil fuels for next 20 years

September 29th, 2014

The chief executive of Siemens infrastructure group says that the world’s economies will continue to be powered by fossil fuels over at least the next two decades.

Speaking at Climate Week in New York, Roland Busch declared that renewables simply hadn’t advanced enough to replace coal and gas and the German multinational would continue to invest in fossils for “the really long term”.

The Guardian reports that despite strong investment in the sector Busch believes reliance on renewables alone does not stand up as a viable solution.

As an indication of Siemens’ approach to the situation, it is continuing to invest in carbon capture and storage technology, with pilot plants in the US and China, and in gas, which generates less carbon when burned than coal.

“You can run Germany on renewable energy on a sunny day when the wind is blowing, but you will still need coal on other days”, Busch said. “A lot of countries are still burning coal. Regardless of how much you push [renewable energy] in the next years you will still have a certain share of energy coming from fossil fuels. We are trying to make that more efficient, more low-carbon, with our technologies. You need coal, at least to some extent.”

“In the next ten to 20 years I can’t imagine running any economies without fossil fuel,” he added. “Beyond 20 years, it’s very hard to say.”

Geoff Morrell, the US spokesman for BP, also made it clear that fossil fuel businesses see a long-term future in carbon-intensive fuels despite efforts to tackle global warming.

“I must be frank with you: it has been very, very hard for us to make money in that [renewable energy] space. Our solar business we tried for 40 years to make solar work, and at the end of the day we just couldn’t make money at it. About a year or two ago, we got out of it. But we still do have a very big biofuels business, particularly in Brazil. We have a very big R&D programme in biofuels. We have 16 wind farms across the country.

So we are trying, but I must tell you it’s a challenging environment to make money in.”
