beta-ray-generator

German Architect Andre Broessel believes he has a solution that can “squeeze more juice out of the sun”, even during the night hours and in low-light regions. His company Rawlemon has created a spherical sun power generator prototype called the beta.ray. His technology will combine spherical geometry principles with a dual axis tracking system, allowing […]

Scientists have clarified the fundamental principles for achieving the synchronization of power generator groups in power networks, which is essential for the stable supply of electric power. Based on this principle, the team developed a method for constructing an aggregated model of a power network that can efficiently analyze and control the behavior of generator groups (including rotor phase angles and connection point voltages) with complex connection to a power grid.

Reducing carbon emissions in order to prevent climate change requires developing new technologies for sustainable and renewable biofuel production. Molecular hydrogen is regarded as one of the most promising energy carriers due to its high energy density and clean, carbon-free use. A research group has discovered an efficient way for transforming solar energy into the chemical energy of biohydrogen through the photosynthesis of green algae that function as cell factories.

Wind Energy News -- ScienceDaily

Wind Energy Information. From offshore wind turbines to understanding wind turbulence, learn all about using the wind to our advantage. Also, wind testing buildings.

Some researchers doubted the feasibility of many of the recent scenarios for high shares of renewable energy. Now scientists have hit back with their response to the points raised. They demonstrate that there are no roadblocks on the way to a 100 percent renewable future.

Steep declines in the use of coal for power generation over the past decade were caused largely by less expensive natural gas and the availability of wind energy -- not by environmental regulations.

Electric vehicles play a key role in China's plan to improve air quality and reduce CO2 emissions but, with the majority of China's electricity still coming from coal-fired power plants, many question just how effective this strategy will be. Now, researchers have found that how electric vehicles are charged -- whether in the low-energy slow mode or high-energy fast mode -- plays a significant role in the reduction of CO2 and the integration of wind energy.

Researchers have developed a way to extract more power from the wind. The researchers used supercomputers at the Texas Advanced Computing Center to filter out the effects of turbulence and apply control algorithms that can better manage the operation of wind farms. The approach has the potential to increase wind power generation by 6-7 percent with a estimated increase in revenue of more than $600 million nationwide.

Silent marine robots that record sounds underwater are allowing researchers to listen to the oceans as never before. While pilot whales make whistles, buzzes and clicks, pods of hunting dolphins create high-pitched echolocation clicks and larger species such as sperm whales make louder, slower clicks. As well as eavesdropping on marine life, the recordings can be used to measure sea-surface wind speed and monitor storms. The research will be presented at the General Assembly of the European Geosciences Union, Vienna.
