Comments Off on Airless tires could help Toyota make lighter electric cars

Airless tires could boost performance and cut down the weight of electric cars – and Toyota is interested. The automaker recently unveiled the hydrogen-powered Fine-Comfort Ride concept car fitted with the tires at the Tokyo Motor Show . The Fine-Comfort Ride is about as big as a crossover SUV, but chief engineer Takao Sato said the airless wheels could be used on any electric car. The airless tires on the Fine-Comfort Ride are comprised of a band of rubber around a plastic-aluminum hub, reports Bloomberg . Sumitomo Rubber Industries supplied the tires for Toyota . Sumitomo unveiled their Smart Tyre Concept, which includes the airless component, at the Tokyo Motor Show and said in a press release , “Airless tires contribute to greater safety and peace of mind in transportation by freeing the driver from worries about punctures and the trouble of having to manage tire pressure.” Sumitomo said there’s interest from other Japanese carmakers as well.

That’s around 30 percent of each tire’s weight, and the development could come as early as 2025. Sumitomo airless tire project head Wako Iwamura said he aims to have a commercial product by 2020, according to Bloomberg, and that his tires are already comparable in price with those requiring air. The company has already been testing the tires on golf carts and minicars. Sumitomo also pioneered what they called the world’s first 100 percent fossil resource-free tires using all-natural materials back in 2013, and said since then they’ve been working to create “proprietary biomass materials based on raw materials derived from plants .” Via Bloomberg Images via Toyota

Comments Off on Leading Stanford climate scientist builds incredible net zero home, complete with Tesla Powerwall

A leading climate scientist — who has dedicated his career to proving the feasibility of transitioning the world off fossil fuels — walks the walk with his personal home. Professor of civil & environmental engineering and director of the Atmosphere/Energy Program at Stanford University, Mark Z. Jacobson has built an incredible Net Zero home using energy-efficient features that enable the house to generate all of its own energy from renewable sources . Jacobson is one of the founders of The Solutions Project , an initiative backed by scientific research that aims to show how every state in the USA can transition to 100 percent renewable energy . Using the organization’s ethos and his own research as a guide, Jacobson worked with luxury custom homebuilders, BONE Structure to design and build his ultra-efficient home . Related: This new energy concept from Sweden can make any building net zero Located in Stanford, California, the structure is the epitome of future efficient home design that doesn’t sacrifice on style or comfort. The project’s planning began by creating an ultra-low energy thermal shell that would insulate the home and reduce energy requirements. Next, to generate and conserve energy, the home was equipped with solar panels along with a couple of Tesla Powerwall battery packs for storage. This system meets all of the home’s energy needs, including heating, cooling, plug loads and even transportation charging. Jacobson moved into his Net Zero home last summer and has been monitoring its performance ever since. Not only does his energy system generate enough clean energy to meet his family’s needs, but Jacobson has also been able to sell 67 percent of the clean electricity back to the utility grid. + BONE Structure

BP and Shell prepare for catastrophic climate change

Comments Off on BP and Shell prepare for catastrophic climate change

International fossil-fuel corporations BP and Shell are preparing for a world in which global temperatures will have risen by 5 degrees Celsius, all but assuring catastrophic climate change , while publicly portraying themselves as supporters of the Paris agreement. A 5 degree temperature increase represents more than double the limit of 2 degrees set out and agreed to by most nations on Earth in the Paris agreement. This difference between publicly supported goals and privately pursued plans represent an effort to mislead the public and shareholders, claims investment campaign group Share Action. Because of the disparity in representing risk of catastrophic climate change by BP and Shell, the pensions of millions are at risk. Beyond the financial implications, such a stance may indicate BP and Shell’s commitment, or lack thereof, to the goal of the Paris agreement. In 2015, BP and Shell shareholders overwhelmingly voted to require the companies to make in-depth disclosures regarding climate risks posed by their business model. Although the companies are meeting their legal requirements, reports from Share Action suggest that they are failing to truly invest in a post-carbon business model required if the planet is to avoid catastrophic climate change. For example, the companies have not set emission reduction targets while their investment in renewable energy has fallen since 2005. BP invests only 1.3 percent of total capital expenditures on clean energy projects, while Shell has declared that it will invest 3 percent of its annual spending on clean energy by 2020. Related: Shell predicted the effects of climate change in its own 1991 film Although Shell recently reaffirmed its commitment to the goals of the Paris agreement (“Shell has a clear strategy, resilient in a 2°C world,” it said in a statement), executives at both BP and Shell are still incentivized to pursue new fossil-fuel heavy projects. “Shell and BP want to have their oil and drink it too, by advocating for the landmark Paris Agreement to limit global temperature rises to below 2°C degrees, while planning for scenarios that would violate it,” said Michael Chaitow, senior campaigns officer at ShareAction. BP and Shell seem to be “poorly prepared for the speed of technological and economic change now underway in the global energy market ,” said Catherine Howarth, chief executive of ShareAction. In response to criticism, BP has said that the company “anticipates a range of scenarios to give us flexibility in our approach.” Via The Independent Images via Depositphotos (1)
