Continental presents concept tire that adjusts to road conditions

When was the last time you checked the air pressure in your car tires ? Most of us don’t pay as much attention to our tires as we should, but Continental recently unveiled two technologies that could pay attention for us. One technology alerts drivers should a tire become damaged, and another could actually change the rim width and tire pressure for better driving on slippery or uneven roads. Continental is showing off their tire technologies, ContiSense and ContiAdapt, at the Frankfurt Motor Show . With the help of sensors embedded in the tire, ContiSense measures temperature and tread depth and then sends that data to a driver over Bluetooth to a smartphone or to a car receiver, with the help of electrically-conductive rubber . If a nail or something else punctures the tire, ContiSense is able to alert the driver far faster than other systems. Related: Continental Tire looks to dandelions for a more sustainable tire ContiAdapt takes a more active role in tire functionality. Micro-compressors in the wheel can adjust the tire pressure on their own, and the system can modify how large the contact patch is to optimize the tire for varying street conditions. There are four combinations so a tire can cruise easily in wet, slippery, uneven, or normal conditions. Continental says the system also allows for very low tire pressure when, for example, a car is navigating deep snow or black ice. Continental also has a concept tire featuring both technologies. This tire design boasts three different tread zones ideal for driving on surfaces that are wet, slippery, or dry. The tread zones are activated depending on the rim width and tire pressure chosen by ContiAdapt. New Atlas said the two technologies will soon be added to Continental’s portfolio, which includes ContiSeal, allowing for automatic sealing of holes, and ContiSilent, which reduces tire and road noise.

The free grocery store fighting food waste and hunger

The Free Store, a non-profit organization and grocery store based in Wellington, New Zealand, is serving food for free and aiding in the fight against food waste . Originally started as a two-week-long art project by artist Kim Paton in 2010, the store has now grown into a more permanent institution, stocking its shelves with surplus food from bakeries and supermarkets. In redistributing free food that would otherwise have gone to waste, the Free Store has proven to be a valuable community space. “There are no conditions on who can come to The Free Store,” said co-founder and director Benjamin Johnson. “There are no criteria. Anybody can come for whatever reason and take whatever they want.” Food waste is a major social problem in New Zealand , as it is in much of the industrialized world. Kiwis, or residents of New Zealand, dispose of approximately $625 million worth of food (120,000 tons) each year. Globally, it is estimated that total food waste weighs up to 1.3 billion tons. Meanwhile, people still go hungry. “We saw the potential in an untapped food supply. You had food that was perfectly good to eat, and then you had people that were hungry . We could facilitate a connection between the two,” said Johnson. Related: Britain’s first zero-waste store is packaging-free and only sells ethical goods The Free Store is made possible through support from volunteers , donors, and around 65 suppliers, located around Wellington city center eager to put their surplus food to good use. According to Johnson, the Free Store distributes between 800 to 1,500 food items each weeknight between 6 PM and 7 PM, averaging about 250,000 food items; that amounts to $1 million worth of food saved per year. Since its establishment, the Free Store has spread to four locations throughout New Zealand, adapting their model and funding structure to fit each area. “All you need is a space to operate from, surplus food, people who need the food and will come and take it, volunteers, and a committed group of people who can actually do it,” said Johnson. “There has to be local ownership. In every area where there’s a Free Store, there needs to be a deeply rooted community of people.” + The Free Store Via EcoWatch Images via The Free Store

Comments Off on Rolling right along: This heat-gathering tire could charge your electric car

What if your car could be powered where the rubber meets the road? Range anxiety persists as a fear among electric car drivers, as heavy batteries with limited capacity remain slow to charge. Goodyear has announced its concept for a heat-gathering, electricity-generating tire at the 2015 Geneva International Auto Show, and the tire could change all that by making a few changes to an oft-overlooked component.

Mercy killing is a difficult concept to stomach, especially when the animals are as adorable as koalas. Unfortunately, nearly 700 koalas were killed by authorities in Australia after they were found to be in extremely poor health due to starvation. Rampant overpopulation has plagued the koala population for years, and the government is facing accusations of poor management of the threatened species.

You see them popping up in your garden, and soon the dandelion may also parked in your driveway . Dutch biotech firm KeyGene has plans to use the latex found in dandelion roots to create a new material for tire production. With global demand for rubber to outstrip current supply by 20 per cent in 2020, the common weed could become a renewable alternative worth nearly $100 billion a year.

Is a Self-Inflating Tire Worth The Extra Cost?

Images credit PumpTire Benjamin Krempel has invented the PumpTire , that keeps a bike tire inflated at the proper pressure. Gizmag explains how it works: Air is drawn from the atmosphere through the one-way valve, which protrudes from the rim like a regular valve stem. Instead of going directly into the inner tube, however, the air goes into one end of a lumen, which is a small tube running along the center of the tire [on the outside]. As the tire rolls against the ground, the lumen is compressed, forcing air out… Read the full story on TreeHugger
