Seventeen years ago, Helen Greiner was scrambling to find investors to back her company’s development of a robot that would clean people’s houses. As she made the rounds of venture capitalists, the responses ranged from “You’re not an Internet company” to “You’re too early stage” to “I would do this, but my partners would kill me.”

But Greiner and her partners, Colin Angle and MIT robotics professor Rodney Brooks, persevered, funneling money from their firm’s contract engineering work to fund the robot project. Today, that company, iRobot Corp. of Bedford, is one of the nation’s largest makers of home robots, generating more than $500 million in annual sales from its Roomba floor vacuum and other products, and employing 600 people, including 500 in Massachusetts.

iRobot is an anchor of a burgeoning Massachusetts robotics industry that includes more than 100 companies, employs more than 3,000, and attracts tens, if not hundreds, of millions of dollars of investments. Since 2008, at least 20 robotics startups have launched in Massachusetts. Venture capital funding of the local industry tripled to more than $60 million in 2012, the most recent year available, from less than $20 million in 2008, according to the Massachusetts Technology Leadership Council, a trade group in Burlington.

Fusion reactors could become an economically viable means of generating electricity within a few decades, replacing conventional nuclear power stations, according to new research at Durham University and Culham Centre for Fusion Energy in Oxfordshire, U.K.

The research, published in the journal Fusion Engineering and Design, builds on earlier findings that a fusion power plant could generate electricity at a price similar to that of a fission plant and identifies new advantages in using new superconductor technology.

The future of Eco conservation?

Deforestation downs 10 billion trees around the globe annually. Replanting trees by hand is slow, expensive, and barely puts a dent in reversing the damage. But one startup wants to use drones that can reforest our increasingly tree-strapped Earth, on a big enough scale to replace slow and expensive hired humans.

The small company, called BioCarbon Engineering, says unmanned aerial vehicles are a great way of covering ravaged woodlands with seedlings that can repopulate the area’s tree population. Around the world, forests and jungles are still being leveled due to lumber overproduction, strip surface mining, urban expansion, and land use for agriculture.

IBM Research has announced a “major engineering breakthrough” that could lead to carbon nanotubes replacing silicon transistors in future computing technologies.

IBM announced a major engineering breakthrough that could open the way to replacing silicon transistors with carbon nanotubes in future electronics and computing technologies.

Silicon transistors have become dramatically smaller in the last decades following Moore’s Law — the observation that the number of transistors per unit area doubles every two tears. However, silicon transistor technology is approaching a point of physical limitation.

With Moore’s Law running out of steam, shrinking the size of transistors — including the channels and contacts — without compromising performance is a research and manufacturing challenge. Carbon nanotube technology could lead to much smaller transistors and keep electronics and computing devices on the Moore’s Law of exponentially decreasing size and thus increasing performance. However, as devices become smaller, increased contact resistance for carbon nanotubes has hindered performance gains until now.

Following Moore’s law is getting harder and harder, especially as existing components reach their physical size limitations. Parts like silicon transistor contacts — the “valves” within a transistor that allow electrons to flow — simply can’t be shrunken any further. However, IBM announced a major engineering achievement on Thursday that could revolutionize how computers operate: they’ve figured out how to swap out the silicon transistor contacts for smaller, more efficient, carbon nanotubes.

The problem engineers are facing is that the smaller silicon transistor contacts get, the higher their electrical resistance becomes. There comes a point where the components simply get too small to conduct electrons efficiently. Silicon has reached that point. But that’s where the carbon nanotubes come in. These structures measure less than 10 nanometers in diameter — that’s less than half the size of today’s smallest silicon transistor contact. IBM actually had to devise a new means of attaching these tiny components. Known as an “end-bonded contact scheme” the 10 nm electrical leads are chemically bonded to the metal substructure. Replacing these contacts with carbon nanotubes won’t just allow for computers to crunch more data, faster. This breakthrough ensures that they’ll continue to shrink, following Moore’s Law, for several iterations beyond what silicon components are capable of.

“These chip innovations are necessary to meet the emerging demands of cloud computing, Internet of Things and Big Data systems,” Dario Gil, vice president of Science & Technology at IBM Research, said in a statement. “As technology nears the physical limits of silicon, new materials and circuit architectures must be ready to deliver the advanced technologies that will drive the Cognitive Computing era. This breakthrough shows that computer chips made of carbon nanotubes will be able to power systems of the future sooner than the industry expected.” The study will be formally published October 2nd, in the journal Science. This breakthrough follows a number of other recent minimization milestones including transistors that are only 3-atoms thick or constructed from a single atom.
