New NASA research brings Warp Speed inches closer to reality: Looks more promising than ever

Posted by in category: physics

In our everyday lives, we may take light for granted, yet for decades, the idea of measuring its attributes and overcoming its obstacles has piqued our interest. First discovered in 1,676 by Danish astronomer Ole Roemer; scientists had previously considered the speed of light was either impossible to measure or unlimited.

Light travels at a speed of 299,792 kilometers per second, which can now be readily found on the internet thanks to the work of other scientists. In 1916, Albert Einstein published his renowned theory of general relativity, in which he said, among other things, that no known object can move faster than the speed of light.

This was a significant moment in history. Attempting to break through that barrier has captivated us ever since, inspiring innumerable creative minds to try their hand at it.

PV-assisted heat pump module facade for power supply, heating, cooling, and ventilation

Posted by in category: energy

Designed by scientists in Germany, the module facade has to be integrated with a building’s technical equipment. The rooms behind the facade can be supplied with solar power and at the same time heated, cooled and ventilated.

Lowering solar module temperatures with radiative cooling, heat pipes

Posted by in categories: solar power, space, sustainability

He said that three main requirements should be fulfilled to improve the cooling effect. The radiative coolers should not replace the existing PV glass covers, so the natural RC ability of glass can be harnessed to add to the overall cooling gain. There should also be an efficient and quick heat transfer mechanism between the PV module, which is also the heat source, and the RC heat sink. In addition, the RC module should directly face the sky to radiate maximum waste heat into outer space.

The proposed system consists of a PV module and a separate RC module, integrated with a flat plate heat pipe in between. A separate RC module is used along with the existing glass cover on the solar cells and the heat pipe is integrated between the PV and RC modules, providing quick heat transfer. The RC module is then placed on the condensing section of the heat pipe facing the sky.

✓ Replaced an engine controller.

We’re continuing to conduct integrated tests inside the Vehicle Assembly Building ahead of the Artemis I launch! The team will work to complete all remaining Space Launch System pre-flight diagnostic tests and hardware closeouts in advance of a mid-February rollout for a wet dress rehearsal in late February. NASA will set a target launch date after a successful wet dress rehearsal test.

India Will Spend $1.6 Billion to Add Lines for Transmitting Green Power

Posted by in categories: government, security, sustainability

India will invest 120 billion rupees ($1.6 billion) to add new lines to transmit electricity from renewable plants as it seeks to draw half of its energy requirement from greener sources by 2030.

Dedicated transmission lines of 10,750 circuit kilometers will be built across seven provinces under the second phase of the so-called green energy corridor project, Information and Broadcasting Minister Anurag Thakur said in New Delhi. The project, approved by Prime Minister Narendra Modi’s cabinet on Thursday, will be completed by 2026 and transmit 20 gigawatts of renewable energy capacity, he said.

India is targeting to build 500 gigawatts of installed power capacity from non-fossil sources by 2030, which would require a transmission network to enable clean electricity to flow from plants to consumers. The new lines will also help integrate renewable energy into the national grid and contribute to long-term energy security, according to the government.

A New Internal Combustion Engine Produces Nearly Zero Harmful Emissions

Posted by in category: sustainability

The world’s first active linear power transfer engine

According to Astron Aerospace, all of this makes the Omega 1 the world’s first engine with an active linear power transfer. “As the Omega 1 engine rotates,” the company says on its website, “all the power is transferred through the single rotating power shaft.” The firm also says the Omega 1 doesn’t require rota seals due to tight tolerances and such high RPMs that there’s not enough time for air to leak.

China’s Shijian-21 towed dead satellite to a high graveyard orbit

Posted by in category: satellites

HELSINKI — China’s Shijian-21 space debris mitigation satellite has docked with a defunct Chinese satellite to drastically alter its geostationary orbit, demonstrating capabilities only previously exhibited by the United States.

Data and tracking from space monitoring firms show that Shijian-21 has been conducting sophisticated rendezvous and proximity operations (RPO) with other objects in and around the geostationary orbit belt since its launch in October last year.
