UK Pledges to Get 100% of Residential Power From Wind Turbines

Posted by in categories: energy, sustainability, transportation

Ramping Up

Johnson announced that the U.K. would invest about £160 million ($207 million) that will go toward factories that would develop new turbines as well as floating offshore turbines themselves. In order to power every home in the U.K., those turbines would need to generate about 40 GW of power, Engadget reports. That’s four times the nation’s current wind energy output.

“Your kettle, your washing machine, your cooker, your heating, your plug-in electric vehicle, the whole lot of them will get their juice cleanly and without guilt from the breezes that blow around these islands,” Johnson announced at the U.K. Conservative party conference.

Is “Peecycling” the Next Wave in Sustainable Living?

Posted by in category: sustainability

Circa 2014


Human waste can be converted into valuable fertilizer, if people can get past the “ick” factor.

Solar-powered machine turns urine into drinkable water

Posted by in categories: media & arts, sustainability

Circa 2016


Scientists from a Belgian university have built a solar-powered machine that can turn urine into drinkable water. They deployed it at a 10-day music and theater festival in central Ghent, Belgium. The experiment was a success as the scientists were able to recover a 1,000 litres of unconsumed water, which will be used to make Belgian beer, from the urine of several partygoers.

Tesla Model GT-R Is Performance Hatchback Insanity

Posted by in categories: sustainability, transportation

“Why would anybody place the front end of a Nissan Skyline GT-R on a Tesla Model 3, even as a rendering?” one might rightfully ask. We’ll, let’s try to answer that.

This in-home water recycler is meant to help the planet, and your wallet

Posted by in category: sustainability

With concerns over water scarcity on the rise, companies are increasingly looking to give people ways to reduce their water consumption. For Hydraloop founder and CEO Arthur Valkieser, the answer was clear: Build a device that gives homeowners and building developers a way to sterilize and reuse their water.

Mercedes-Benz teases new EQS and EQE luxury electric vehicles

Posted by in categories: sustainability, transportation

Mercedes-Benz teased two new electric vehicle variants, the EQS and EQE, which will both come in sedan and SUV models. The automaker plans to release six new electric vehicles over the next two years.

Tesla reportedly eliminates its PR department

Posted by in categories: sustainability, transportation

Tesla apparently has a new strategy for dealing with journalists: Don’t deal with them at all.

The electric car giant has dissolved its global public relations team, leaving the press with no formal point of contact at the world’s most valuable automaker, a new report says.

Essentially every staffer who used to work in Tesla’s PR office has either moved to a different position at the company or left altogether, according to electric vehicle industry blog Electrek, which said the move to disband the department was confirmed “at the highest level at Tesla.”

Tesla in talks with Vale to buy Canadian nickel for electric cars

Posted by in categories: Elon Musk, sustainability, transportation

Tesla CEO Elon Musk in July urged miners to produce more nickel, a key ingredient in the batteries that power the company’s electric cars. Musk offered a “giant contract” if supplies could be produced in an environmentally sensitive way.

While EVs are expected to help reduce global carbon emission, environmentalists are concerned that production of EV parts and increased mining may damage the environment.

Tesla Model 3 crushes Dodge Charger in 1-year review of cost of operation as police car

Posted by in categories: sustainability, transportation

Tesla Model 3 is crushing Dodge Charger as a police car when it comes to the cost of ownership as the Bargersville Police Chief who pushed to electrify his fleet shares a 1-year review of the cost of operation.

Last year, we reported on the Bargersville, Indiana, police department updating their fleet with Tesla Model 3 vehicles.

Bargersville Police Chief Todd Bertram commented at the time:

Giant electrochemical actuation in a nanoporous silicon-polypyrrole hybrid material

Posted by in categories: biological, chemistry, computing, cyborgs, sustainability

The absence of piezoelectricity in silicon makes direct electromechanical applications of this mainstream semiconductor impossible. Integrated electrical control of the silicon mechanics, however, would open up new perspectives for on-chip actuorics. Here, we combine wafer-scale nanoporosity in single-crystalline silicon with polymerization of an artificial muscle material inside pore space to synthesize a composite that shows macroscopic electrostrain in aqueous electrolyte. The voltage-strain coupling is three orders of magnitude larger than the best-performing ceramics in terms of piezoelectric actuation. We trace this huge electroactuation to the concerted action of 100 billions of nanopores per square centimeter cross section and to potential-dependent pressures of up to 150 atmospheres at the single-pore scale. The exceptionally small operation voltages (0.4 to 0.9 volts), along with the sustainable and biocompatible base materials, make this hybrid promising for bioactuator applications.

An electrochemical change in the oxidation state of polypyrrole (PPy) can increase or decrease the number of delocalized charges in its polymer backbone (1). Immersed in an electrolyte, this is also accompanied by a reversible counter-ion uptake or expulsion and thus with a marcroscopic contraction or swelling under electrical potential control, making PPy one of the most used artificial muscle materials (15).

Here, we combine this actuator polymer with the three-dimensional (3D) scaffold structure of nanoporous silicon (68) to design, similarly as found in many multiscale biological composites in nature (9), a material with embedded electrochemical actuation that consists of a few light and abundant elemental constituents (i.e., H, C, N, O, Si, and Cl).
