The truck has smart systems including radars, cameras and active speed regulators and works without a human driver — although one has to be in the driver’s seat and take the wheel if necessary.

The standard Mercedes-Benz Actros, fitted with the intelligent “Highway Pilot” system, travelled 14 kilometres (about nine miles) on the A8 motorway, with a driver in the cabin but his hands off the wheel.

“Today’s premiere is a further important step towards the market maturity of autonomously driving trucks -– and towards the safe, sustainable road freight transport of the future,” said Wolfgang Bernhard, board member responsible for Daimler Trucks and Buses.

Physicists have developed a method to synthesise a unique and novel type of material which resembles a graphene nanoribbon but in molecular form. This material could be important for the further development of organic solar cells.

Transparent solar panels!

Imagine a city that’s actually a vast solar energy harvesting system. A team of Michigan State University researchers has developed a technology that can turn transparent surfaces, from building windows to cell phones, into solar collecting surfaces – without obstructing the view.

Tesla CEO Elon Musk recently did an interview in Denmark where he talked about all sorts of topics. Naturally, he spoke about where he see the future of the EV market going. The big problem that EV buyers have today are relatively short driving ranges offered. Tesla has the best driving range with its Model S able to go several hundred miles on a charge.

Musk answered a question from the interviewer on when we can expect to see EVs able to drive 1000km per charge, which is about 612 miles. Musk said that a Model S has already gone 500 miles on a charge, at low speeds.

He thinks that the Model S might be able to go 500 miles per charge by next year, but definitely by 2017. By 2020 Musk thinks that a driving distance of 1200 km, or about 746 miles, will be possible per charge. It’s unclear if Musk was talking about normal driving distance or hypermiling the EV.

Stanford engineers have developed a transparent silicon overlay that can increase the efficiency of solar cells by keeping them cool. The cover collects and then radiates heat directly into space, without interfering with incoming photons. According to a local HVAC Spokane, WA company, “If mass-produced, the development could be used to cool down any device in the open air – for instance, to complement air conditioning in cars.”

After a full day in the sun, solar cells in California can approach temperatures of 80° C (175° F), even in winter months. Excessive heat can pose problems because, while the cells need sunlight to harvest energy, they also lose efficiency as they heat up. A standard silicon cell, for example, will drop from 20 to 19 percent efficiency by heating up just 10° C (18° F) or so.

Laptops address the overheating problem with the help of carefully engineered fans and heat sinks, but for solar panels and other devices that work in the open air, space itself could serve as heat sink par excellence. The coolness of space, approaching absolute zero, would negate the need for elaborate and expensive heat dissipation contraptions – if only we had a way to access it from the ground.

The Solar City Tower, designed by RAFAA, includes a bank of solar panels as well as pumped water storage to create energy during both the day and night for use in the Olympic Village.

Shawn Frayne and Alex Hornstein, two young inventors based in the Philippines, are taking their passion for clean free energy and developing a way to make it accessible and cheap for everyone. These guys are working restlessly to provide a product that could be used by practically anyone to make homemade solar panels.

The factory is small enough to fit on a desktop and efficient enough to produce 300k to one million panels per year, up to one every 15 seconds. By cutting out much of the labor intensive process, which represents 50% of the total cost, this machine can dramatically reduce the price of solar. Their pocket solar panel producer can change the way the world views electricity. Image credit: YouTube/SciFri

An art professor from Syracuse University in the US, Van Aken grew up on a family farm before pursuing a career as an artist, and has combined his knowledge of the two to develop his incredible Tree of 40 Fruit.

In 2008, Van Aken learned that an orchard at the New York State Agricultural Experiment Station was about to be shut down due to a lack of funding. This single orchard grew a great number of heirloom, antique, and native varieties of stone fruit, and some of these were 150 to 200 years old. To lose this orchard would render many of these rare and old varieties of fruit extinct, so to preserve them, Van Aken bought the orchard, and spent the following years figuring out how to graft parts of the trees onto a single fruit tree.

Working with a pool of over 250 varieties of stone fruit, Van Aken developed a timeline of when each of them blossom in relationship to each other and started grafting a few onto a working tree’s root structure. Once the working tree was about two years old, Van Aken used a technique called chip grafting to add more varieties on as separate branches. This technique involves taking a sliver off a fruit tree that includes the bud, and inserting that into an incision in the working tree. It’s then taped into place, and left to sit and heal over winter. If all goes well, the branch will be pruned back to encourage it to grow as a normal branch on the working tree.
