Finance and investment companies as well as customers looking for more environmentally responsible portfolios have all caught the ESG bug.
Did you know that much of what we buy is built for obsolescence significantly contributing to pollution and global warming?
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.
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.

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.

President Biden praised Ford and General Motors for investing billions of dollars into building electric vehicles – but didn’t mention Tesla.
The Dongfeng E70 electric sedans were announced as the world’s first commercially available electric vehicles with a solid-state battery when they were delivered as part of a taxi fleet. Now the energy density of the E70’s battery pack and its range on a charge have been outed, and they are pretty run-of-the-mill.
At the secluded British airfield of Old Buckenham, an electric light aircraft is now being charged with solar power. After all, electric aircraft are a robust, low-maintenance alternative to fossil fuel-powered ones.
