The Zero Bills Home

The Zero Bills Home build at the BRE Innovation Park in UK represents the first show home for a new 96 home zero bills development in Newport Essex for the Sir Arthur Ellis family Trust. Newport is 8 miles from Stansted and 15 miles from Cambridge. The new zero bills village is 150 yards from a station on the Bishopsgate / Cambridge railway line.


Superinsulated concrete foundation slab with optional additional piles to match most ground conditions.Laser cut galv steelpowder coated structural ring beam with C16 UK timber studs. UK fabricated OSB structural boards enables one floor to be built every two days. Superinsulated cladding with heat recovery ventilation and triple glazing reduces heat demand to the point where a tiny heat pump can provide comfort and hot water. ZED Factory designed BIPV solar roofing system provides durable roof with electric generation and optional solar loft conservatory. Good daylight, water saving appliances and LED lighting reduces electric demand allowing surplus solar electricity to power an electric car. A smart LIPO4 Fitcraft battery system, positioned under the stair stores solar electricity, minimising grid imports and limiting grid export to 3kW maximum avoids the need to upgrade the existing mains grid infrastructure. The system enables simple, adaptable plans which create convenient internal layouts for any plot orientation.

The system build costs at scale are circa £1450- £1650/ m2 (around 1500 euros/m2) for a completed building which compares favourably with current costs of meeting building regulations. Combined with no net annual energy bills and the potential to achieve higher resale values based on the additional features of the building, the ZBH system offers a cost effective and sustainable alternative to traditional builder offerings. 


Human Internal Verbalizations Understood Instantly By Computers

MIT researchers have developed a computer interface that can transcribe words that the user verbalizes internally but does not actually speak aloud. The system consists of a wearable device and an associated computing system. Electrodes in the device pick up neuromuscular signals in the jaw and face that are triggered by internal verbalizations — saying wordsin your head” — but are undetectable to the human eye. The signals are fed to a machine-learning system that has been trained to correlate particular signals with particular words. The device also includes a pair of bone-conduction headphones, which transmit vibrations through the bones of the face to the inner ear. Because they don’t obstruct the ear canal, the headphones enable the system to convey information to the user without interrupting conversation or otherwise interfering with the user’s auditory experience.

The device is thus part of a complete silent-computing system that lets the user undetectably pose and receive answers to difficult computational problems. In one of the researchers’ experiments, for instance, subjects used the system to silently report opponents’ moves in a chess game and just as silently receive computer-recommended responses.

The motivation for this was to build an IA device — an intelligence-augmentation device,” says Arnav Kapur, a graduate student at the MIT Media Lab, who led the development of the new system. “Our idea was: Could we have a computing platform that’s more internal, that melds human and machine in some ways and that feels like an internal extension of our own cognition?” “We basically can’t live without our cellphones, our digital devices,” adds Pattie Maes, a professor of media arts and sciences and Kapur’s thesis advisor. “But at the moment, the use of those devices is very disruptive. If I want to look something up that’s relevant to a conversation I’m having, I have to find my phone and type in the passcode and open an app and type in some search keyword, and the whole thing requires that I completely shift attention from my environment and the people that I’m with to the phone itself. So, my students and I have for a very long time been experimenting with new form factors and new types of experience that enable people to still benefit from all the wonderful knowledge and services that these devices give us, but do it in a way that lets them remain in the present.”


Revolutionary NanoDrops Replace Glasses

Israeli scientists and clinicians appear to have come up with “revolutionary” eye-drops that can correct short– or long-sightedness and eliminate the need for glasses. The so-called ‘nano-drops’ have been developed by a team at Sha’are Zedek Medical Center and Bar-Ilan University’s Institute of Nanotechnology and Advanced Materials.

They have been shown to improve both short-sightedness (myopia) and long-sightedness (hyperopia) in tests on pigs, with plans to begin clinical testing on humans later this year.

If the drops are found to improve human vision then the nano-drops solution could eliminate the need for glasses and “revolutionise ophthalmological and optometry treatment”.

Prospective patients would use a smartphone app to scan their eyes, measure their refraction, create a laser pattern then apply a “laser corneal stamping” of an optical pattern onto the corneal surface of their eyes.


Taiwanese Electric SuperCar Aims To Take On Tesla

Hailed as the world’s first electric supercar with onroad and offroad capabilities, the “Miss R” is the company’s electric vehicle (EV) designed for serious performance driving. Harnessing a four-wheel torque vectoring system capable of launching it at roughly 168 MPH (270 km/h), 4 independent electric motors rated at 350V each will give the Miss R the edge over Tesla’s future Roadster 2.0 (base version). The 0–60 MPH will be covered in 1.8 seconds and the 0–124 MPH (200 km/h) in a blistering 5.1 seconds.


What makes the Electric Supercar XING Mobility Miss R different from other high-end performance EVs is that it is designed to reach that performance on almost any road surface. On-road, on-track, and off-road is the leitmotiv of the company that wants to offer a versatile driving experience no matter what the pavement.

According to XING Mobility’s Co-founder and CEO, Royce YC Hong: “Miss R is the embodiment of the paradigm shift of EVs surpassing traditional combustion-engine cars in both performance and capability. The core idea behind the prototype is to achieve game-changing performance levels and driving experiences that are otherwise impossible to achieve in a gasoline-powered vehicle.” Indeed, XING Mobility is out to prove once and for all that the electric drivetrain is far superior to its contemporary internal combustion engine (ICE) cousin.


Ultra-Powerful Batteries

From smartphones to electric vehicles, many of today’s technologies run on lithium ion batteries. That means that consumers have to keep their chargers handy. An iPhone X battery only lasts for 21 hours of talk time, and Tesla’s model S has a 335-mile range—which means you could expect to make it from Newark, Delaware to Providence, Rhode Island, but not all the way to Boston, on one charge. Scientists all over the world—including  even the inventor of lithium ion batteries himself, John Goodenough—are looking for ways to make rechargeable batteries safer, lighter, and more powerful.

Now, an international team of researchers led by Bingqing Wei, a professor of mechanical engineering at the University of Delaware and the director of the Center for Fuel Cells and Batteries, is doing work that could lay the foundation for more widespread use of lithium metal batteries, which have more capacity than the lithium ion batteries commonly used in consumer electronics today. The team developed a method to mitigate dendrite formation in lithium metal batteries, which they  have described in a paper published in Nano Letters.

In a lithium ion battery, the anode, or current-generating side, is made of a material, such as graphite, with lithium ions bound to it. The lithium ions flow to the cathode, or current-collecting side.

In a lithium metal battery, the anode is made of lithium metal. Electrons flow from the anode to the cathode to generate electricity. Rechargeable batteries made of lithium metal hold a lot of promise because lithium is the most electrically positive metal and has a very high capacity.

“Theoretically, lithium metal is one of the best choices for batteries, but it is hard to handle in practice,” Wei said.

Lithium metal batteries have been inefficient, unstable, and even a fire hazard thus far. Their performance is hampered by lithium dendrites, formations that look like tiny stalagmites made of lithium deposits. As a battery is being used, lithium ions collect on the anode. Over time, the lithium deposits become non-uniform, leading to the formations of these dendrites, which can cause the battery to short circuit.
