Power consumption of robot joints could be 40 perecnt less, according to a laboratory study

A laboratory study has found that taking into consideration both the current and previous orders in flexible joints can significantly reduce energy consumption. The researchers used polynomial or fractional order reconstructions, which may be of interest for robot elbows and wrists, with potential savings up to 40%.

The efficient choice among combustion engines

Researchers at ETH Zurich developed an internal combustion engine that achieves fuel efficiency of less than 2.4l per 100km while emitting less than half the CO2 compared to traditional engines. The natural gas-diesel hybrid engine uses sophisticated control engineering and innovative electronic combustion control.

Solar power from plastic foils

A group of KIT researchers has been granted €4.25 million to enhance the efficiency of organic solar cells to over 10% using tandem architectures and novel materials. The new generation of solar cells is light, flexible, semi-transparent, and can be produced at low cost.

Polluting China for the sake of economic growth

A study analyzing data from 30 Chinese provinces found that energy consumption has a greater impact on output than labor, while pollution has little effect. China must implement effective environmental regulations to reduce pollution and energy consumption and bind economic growth with environmental protection.

Using its own technology for electric microgrids

The Public University of Navarre and CENER have developed two electricity microgrids to enhance energy efficiency, reduce contaminant emissions, and increase safety in supply. The microgrids feature a combination of renewable energy sources and storage systems, enabling efficient operation in both grid-connected and isolated modes.

Chain hotels lead the way in going green

A WSU study suggests chain hotels are more likely to adopt energy-efficient light bulbs, train staff to reduce waste, and educate guests on water conservation. This trend may give independents a competitive disadvantage in attracting customers. Hotels can save up to $6.75 per day by implementing greener practices.
