Elon likes pipe dreams.. :)
The San Mateo, California-based solar supplier is the first in line to incorporate Tesla’s new batteries, offering a “turnkey residential solar battery backup system” at a price point that’s more than 60 percent less than previous solar power storage products, SolarCity announced.

SolarCity has already started taking orders for Tesla’s residential batteries and will begin installations in October. According to Bloomberg, customers can prepay $5,000 for a nine-year lease on a 10 kilowatt-hour system. Customers can also buy the entire system for $7,140. The prices reportedly include installation, a maintenance agreement, the electrical inverter and control systems.

It’s clear that the benefits of a solar battery system goes beyond having electricity after the sun sets or when the power is out. “It is vital that we advance the technologies that will lead to an affordable, decarbonized grid. The widespread availability of affordable battery storage will unlock the full potential of solar energy to contribute to this effort,” wroteMusk’s cousin/SolarCity co-founder and Chief Technology Officer Peter Rive in a blog post about the batteries. “I believe that the solar battery systems launched today will result in a record amount of batteries being deployed in the U.S., advancing our goal of ensuring a cleaner future for all.”

Yeah it's all just a pipe dream on any large scale
I have no use for large-scale power, personally. The only thing that even needs 220v at my place is the well pump, which most people don't have. In the grand scheme of things we would all be better off with personal renewable power generation, charging our smartcars off the panels on the roof of our houses. Then we can leave the dirty power for the industrial applications that require it, and breath cleaner air as a result.

Tesla's New Battery Doesn't Work That Well With Solar
Even Elon Musk's SolarCity, the biggest supplier in the U.S., isn't ready to install Tesla's home battery for daily users

Tesla Chief Executive Elon Musk introduced a new family of batteries designed to stretch the solar-power revolution into its next phase. There's just one problem: Tesla's new battery doesn't work well with rooftop solar—at least not yet. Even Solar City, the supplier led by Musk, isn't ready to offer Tesla's battery for daily use.

The new Tesla Powerwall home batteries come in two sizes—seven and 10 kilowatt hours (kWh)—but the differences extend beyond capacity to the chemistry of the batteries. The 7kWh version is made for daily use, while its larger counterpart is only intended to be used as occasional backup when the electricity goes out. The bigger Tesla battery isn't designed to go through more than about 50 charging cycles a year, according to SolarCity spokesman Jonathan Bass.

Here’s where things get interesting. SolarCity, with Musk as its chairman, has decided not to install the 7kWh Powerwall that’s optimized for daily use. Bass said that battery "doesn't really make financial sense" because of regulations that allow most U.S. solar customers to sell extra electricity back to the grid.1

For customers of SolarCity, the biggest U.S. rooftop installer, the lack of a 7kWh option means that installing a Tesla battery to extend solar power after sunset won't be possible. Want to use Tesla batteries to move completely off the grid? You'll just to have to wait. “Our residential offering is battery backup,” Bass said in an e-mail.

A Tesla spokeswoman, Khobi Brooklyn, said via e-mail that both sizes of the Powerwall battery would be available in the U.S. by late summer. She didn't say which distributors will offer the smaller battery designed for everyday use. Tesla is set to report earnings later Wednesday, although the new line of home batteries will probably take a back seat to sales of the company's battery-powered cars.

The first self-driving 18-wheeler hits the highways

Daimler's Freightliner Inspiration Truck is fully licensed to self-drive on Nevada's highways.

Nevada OKs it for use on state highways

Daimler Trucks this week unveiled what it said is the world's first licensed 18-wheel semi-tractor trailer that can drive itself.

Daimler unveiled the new 18-wheeler yesterday during a ceremony at the Hoover Dam.

The Freightliner Inspiration Truck, a concept truck, underwent extensive testing, Daimler said, before the Nevada Department of Motor Vehicles granted it a license to operate on public roads in the state. This past year, the truck was driven more than 10,000 miles during a test in Germany.

Daimler said its new self-driving rig "promises to unlock autonomous vehicle advancements that reduce accidents, improve fuel consumption, cut highway congestion, and safeguard the environment."

The Freightliner Inspiration Truck

"Freightliner Trucks has been setting the standard for commercial vehicle design and technology for nearly 75 years," said Martin Daum, CEO of Daimler Trucks North America.

The Inspiration Truck's autonomous features are enabled by forward-facing radar, a stereo camera and Daimler's adaptive cruise control, which automatically adjusts distances between vehicles to maintain highway speed. Many of the autonomous vehicle systems in the concept truck are already deployed in Daimler Truck's current rig, the Freightliner Cascadia Evolution.

The radar unit is located in the center area of the Freightliner Inspiration Truck front bumper and it scans the road ahead at long and short range. The long-range radar, with a range of 820 feet, scans an 18-degree view to provide both narrow and far views. The short-range radar, with a range of 230 feet, has a scanning range of 130-degrees; it looks wider for vehicles that might cut in front of the truck.

The front radar unit is the basis for the Active Cruise Control and Active Brake Assist available in the Detroit Assurance suite of safety systems on the series production Freightliner Cascadia Evolution.

The area ahead of the truck is also is scanned by a stereo camera located behind the Freightliner Inspiration Truck windshield. The range of the camera is 328 feet, and it scans an area of 45-degrees horizontal by 27-degrees vertical. The camera recognizes lane markings and communicates to the Highway Pilot steering gear for autonomous lane guidance.


The location of the autonomous radar and camera technology.

Daimler's Highway Pilot computer system links the camera and radar technology with systems that provide lane stability, collision avoidance, speed control, braking, steering and an advanced dash display.

"Putting the Freightliner Inspiration Truck on the road is an historic day for Daimler Trucks and the North American trucking industry," said Wolfgang Bernhard, a member of the Board of Management of Daimler AG Daimler Trucks and Buses. "Our team has done a marvelous job in bringing this breakthrough technology to the road."

^^ That makes me feel a little uneasy as I have never had a computer (commodore 64 to now) that did not screw up now and then.

Back to Elon's battery wall for a second.. as of the 6th

During Tesla's earnings call, CEO Elon Musk just announced that the company has so far taken 38,000 reservations for its Powerwall home battery. "The response has been overwhelming. Like, crazy," Musk said. He went on to describe the reception to Tesla Energy's introduction as "crazy off the hook." Tesla has also tallied 2,500 reservations for the PowerPack. Musk said this actually equates to more like 25,000 since reservations averaged around 10 Powerpacks each. "The volume of demand here has just been staggering," he said. "It really feels like, man, the stationary storage demand is just nutty. Like, worldwide, it’s just crazy."

If he can increase mileage by 40% with a freaking software update only, I think he can figure the solar issue out. ;)

Not only that but it seems like we cant even keep a train on the rails lately :doh:

Awesome news; I can see folks filling these batteries up during off-hours when it's cheap, and then using the power off the batteries during "peak power" hours when electricity is more expensive :tup:

And in other news . . .

New images from Dawn of Ceres showing the bright spots which scientists, whoever they are, still think might be ice. This animation shows a sequence of images taken by NASA's Dawn spacecraft on May 4, 2015, from a distance of 8,400 miles (13,600 kilometers), in its RC3 mapping orbit. The image resolution is 0.8 mile (1.3 kilometers) per pixel.

In this closest-yet view, the brightest spots within a crater in the northern hemisphere are revealed to be composed of many smaller spots. However, their exact nature remains unknown.

Pretty interesting how those 2 bright spots appear to be bright even when coming from the shady side on the left side .. The others suggest reflection to me as they fade into the darkness on the right. No therories other than ice?

Cool image!

Away with the fairies
Paralyzed from the neck down after suffering a gunshot wound when he was 21, Erik G. Sorto now can move a robotic arm just by thinking about it and using his imagination. By implanting neuroprosthetics in a part of the brain that controls not the movement directly but rather our intent to move, Caltech researchers have developed a way to produce more natural and fluid motions.

Nasa cancels LDSD launch

Nasa has had to cancel its third attempt at launching a rocket-powered flying saucer into space.

The company hopes that it can test out the science fiction-looking ship in advance of using it as a way of landing deliveries on Mars. But the tests have been called off a number of times, most recently because rain showers and wind moved hit the Hawaii launch site.

“A line of rain showers developed overnight moving towards the launch site, which result in unstable wind conditions near the surface that would prevent the launch of the balloon,” Nasa spokesperson Kim Newton said in a post about the called-off mission. Nasa said that it would look to launch it again tomorrow.

When the ship does finally launch, it will be carried up on a giant weather balloon to a spot 120,000 feet above Hawaii. It’ll then be carried up another 180,000 feet, carried up by a rocket booster, mimicking the speed it’ll travel during its descent to Mars.

The landing mechanism will then deploy as the ship comes back down to Earth — first the huge balloon in the flying saucer will deflate, and then a parachute will open out.

If that works, scientists hope to adapt the technology for the future Mars missions. That is important because the thin atmosphere on Mars makes it difficult to get to the ground — there’s less air to slow them down, so too often they crash into the ground and can break.

But the LDSD is built to pick up as much air resistance as it can, with its big round shape — similar to a classic UFO — helping to create drag. The extra parachutes help slow it down even more, hopefully landing equipment or even humans on the red planet.

SpaceX and GoPro together, beautiful HD . . . :)

A GoPro inside a fairing from a recent Falcon 9 flight captured some spectacular views as it fell back to Earth. Footage is played in real time.

Music: Blue Danube by Johann Strauss II


In other news . . . Airbus unveiled today its prototype design to recover and reuse the engines and avionics of its Ariane rockets. This is in direct response to SpaceX attempting to do the same. Competition at its best.

Robot fitted with katana to create world's most efficient samurai


Amid worries that AI will one day outstrip human intelligence and lead to our downfall, a Japanese technology has decided to fit a robot with a deadly katana sword, yay!

It posted a video of the robotic arm showing off its deft skill with a blade, which it learnt by motion capturing Japanese swordsman Isao Machii.

The robot takes on Machii in a number of challenges, performing complicated angled cuts and managing to slice with such speed and precision that it can easily halve a runner bean lengthways.

While he might not be able to match the robot, as humans go Machii is pretty swift, having recently sliced a fried shrimp fired at him at 80mph.

Robotic arms such as these are getting better and better at mimicking human movements, with one recently beating a world table tennis champion.

This "urban algae canopy" produces as much oxygen as four hectares of woodland :tup:

QbCeil5.jpg

The Urban Algae Canopy was presented as a prototype at this year’s Expo Milano. The project was presented by London-based ecoLogicStudio as part of The Future Food District project.


The bio-digital structure pumps a fluid with microalgae around a transparent shelter, which in turn produces shade, energy in the form of biomass, and an impressive amount of oxygen.



When the sun shines intensively, the algae will photosynthesize and grow, which in turn will reduce the transparency of the canopy and provide shade.

Using images that Dawn has accumulated since it entered orbit around Ceres, scientists, whoever they are, have created an animation showing the dwarf planet as it rotates. The images come from Dawn's first mapping orbit at Ceres, at an altitude of 8,400 mile (13,600 kilometers), as well as navigational images taken from 3,200 miles (5,100 kilometers) away. The images provided information for a three-dimensional terrain model. The vertical dimension has been exaggerated by a factor of two, and a star field has been added in the background.
