A Stanford University professor whose research helped underpin the U.S. Democrats’ Green New Deal says phasing out fossil fuels and running the entire world on clean energy would pay for itself in under seven years.

And a means coming for 24 hour power supply.
First announced in 2012 and with a scheduled completion date of 2030, the 5,000-megawatt solar park will take three times as long to finish as the Burj Khalifa. Phases one and two, which are already complete, comprised 2.3 million photovoltaic panels with a capacity of 213 megawatts. Phase three, deep in construction, adds over 3 million photovoltaics and another 800 megawatts, and will be completed in 2020, say DEWA.
This 45-ton dump truck ascends a 13-percent grade and can take on 65 tons while doing so.
As the heavy transport descends with more than double the weight, the trucks regenerative braking system recaptures all the energy it will need to refill the charge that it will need to use on the way back up again. Regenerative braking allows the eDumper to produce more energy downhill than it consumes uphill.”
The eDumper is the world’s largest electric vehicle but it generates more energy than it uses so it never needs charging.
Today, IBM Research is building on a long history of materials science innovation to unveil a new battery discovery. This new research could help eliminate the need for heavy metals in battery production and transform the long-term sustainability of many elements of our energy infrastructure.
As battery-powered alternatives for everything from vehicles to smart energy grids are explored, there remain significant concerns around the sustainability of available battery technologies.
Many battery materials, including heavy metals such as nickel and cobalt, pose tremendous environmental and humanitarian risks. Cobalt in particular, which is largely available in central Africa, has come under fire for careless and exploitative extraction practices.1
Nawa’s Racer goes farther than other e-bikes thanks to an ultracapacitor that harvests more brake energy.
O.o.
If L.A. succeeds, a hydrogen-burning Intermountain Power Plant could become a model for governments and electric utilities around the world.
We are NOT our age we are our ENERGY
TIME is not real – it is a human construct to help us differentiate between now and our perception of the past, an equally astonishing and baffling theory states.
The NREL scientists, along with colleagues at Yale University, Argonne National Laboratory, and Oak Ridge National Laboratory, are part of the Department of Energy’s Co-Optimization of Fuels & Engines (Co-Optima) initiative. Co-Optima’s research focuses on improving fuel economy and vehicle performance while also reducing emissions.
“If you look at biomass, 30% of it is oxygen,” said Derek Vardon, a senior research engineer at NREL and corresponding author of a new paper detailing the Co-Optima research project. “If we can figure out clever ways to keep it around and tailor how it’s incorporated in the fuel, you can get a lot more out of biomass and improve the performance of diesel fuel.” The molecule, 4-butoxyheptane, contains oxygen while conventional petroleum-derived diesel fuel is comprised of hydrocarbons. The presence of oxygen significantly reduces the intrinsic sooting tendency of the fuel upon burning.
The paper, “Performance-advantaged ether diesel bioblendstock production by a priori design,” appears in the journal Proceedings of the National Academy of Sciences. Vardon’s co-authors from NREL are Nabila Huq as the first author, with co-authors Xiangchen Huo, Glenn Hafenstine, Stephen Tifft, Jim Stunkel, Earl Christensen, Gina Fioroni, Lisa Fouts, Robert McCormick, Matthew Wiatrowski, Mary Biddy, Teresa Alleman, Peter St. John, and Seonah Kim.
Nanoscale experiments reveal that quantum effects can transmit heat between objects separated by empty space.
Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have one or many variables in any combination, and the magnitude of them is decided by what power the variables are taken to. So x + 4 is an expression describing a straight line, but (x + 4)² is a curve. Since a line crosses just once through any particular latitude or longitude, its solution is just one value. If you have x², that means two root values, in a shape like a circle or arc that makes two crossings.
