Royal BAM announces ‘world’s first’ fully electric asphalt road paver with dual electric motors and a pair of massive 270 kWh batteries!
Dutch civil engineering company Royal BAM has announced a fully-electric asphalt spreading road paver, which will save more than 93,000 kilograms of CO₂ and 115,000 grams of nitrous oxide emissions compared to its bio-diesel counterparts.
Working together with partners at Wirtgen and New Electric, BAM has replaced the vegetable-oil sourced, bio-diesel powered Volvo Penta Stage V engines with an electric drive, consisting of two “smartly switched electric motors” that pull electrons from a massive 270 kWh battery. For those you keeping score, that’s more than twice as big as the battery used in the 500-mile range Lucid Air electric sedan. (!)
Once the work is done and the road is paved, the Royal BAM machine can power up it’s second 270 kWh battery (!!) and drive itself to the next project, or back to the fleet depot after a long working day.
‘A watershed in furthering our understanding of these structures,’ researcher says.
An unprecedented new telescope image of the Milky Way galaxy’s turbulent center has revealed nearly 1,000 mysterious strands, inexplicably dangling in space.
Stretching up to 150 light years long, the one-dimensional strands (or filaments) are found in pairs and clusters, often stacked equally spaced, side by side like strings on a harp. Using observations at radio wavelengths, Northwestern University ’s Farhad Yusef-Zadeh discovered the highly organized, magnetic filaments in the early 1980s. The mystifying filaments, he found, comprise cosmic ray electrons gyrating the magnetic field at close to the speed of light. But their origin has remained an unsolved mystery ever since.
The Concorde’s successor might be quieter.
NASA has completed the first test of the works on lowering the volume of supersonic flights in an effort to lift the ban on commercial supersonic flights, NASA’s Glenn Research Center announced.
The sonic booms happen when the merge of shock waves, created by breaking the sound barrier at the speed of 767 mph (1,235 kph). The huge amount of sound energy, approximately 110 decibels, generated by sonic booms sounds like thunderclaps or explosions and can be heard from 30 miles (48 km) away, which is why supersonic commercial flights are banned by the Federal Aviation Administration (FAA). physicists confirm that they have achieved a stage in nuclear fusion called “burning plasma”.
A standard feature on its Model S, Model X, and Model Ys since 2016.
As Tesla explains in the description accompanying the video, it uses highly efficient particulate air (HEPA) filters in its car models S, X, and Y. The air filtration system removes more than 99 percent of particulates and is something we also saw in some other EV concepts last year.
To demonstrate the efficiency of the filters in its car, Tesla engineers blew up a large bubble and filled up the interiors with smoke from smoke bombs. For comparison, they also put a BMW X3, without a HEPA filter, inside the bubble. Musk confirms the Cybertruck is delayed until 2023.

Country’s top two utility operators make massive investments in green energy
China said it will continue accelerating domestic grid network construction this year with a focus on ultrahigh-voltage power transmission networks.
It will mark an attempt to further ensure power supply stability and boost green power consumption in the country.
