Researchers at Rice University have announced the discovery of a new breakthrough method for producing carbon nanotubes in bulk fluids. Rice’s new nanotube “stew” could spur the inexpensive mass production of carbon nanotube-based products, much like the plastics industry employed bulk loads of melted polymers as a cheap base for making everything from medical equipment to polyester shirts to plastic bags, and countless other things in between.
Rice’s nanotube research was sponsored in party by U.S. Air Force and U.S. Navy. Aside from their military application, carbon nanotubes have a practically unlimited potential for sustainable civilian products because of their strength, light weight, and electrical conductivity among other properties. Lightweight nanomaterials could boost the gas mileage in cars and airplanes, make thinner and more flexible solar cells, increase the efficiency of lithium-ion batteries (in combination with another new high tech material, graphene), and be used in artificial photosynthesis to generate hydrogen fuel.
Leo Motors, a parts supply company with its roots in Korea, has an outspoken CEO with an interesting eye for the future and a grasp of where we’ve come from. For instance, after speaking with him it became apparent that Dr. Robert Kang has come to the conclusion that most of the electric vehicle technology we see today is based on technology developed for electric toys combining a simple motor, battery and ampere controller.
I don’t know if this is a fully accurate representation of electric car design, but it’s certainly true that electric cars are relatively simple systems.
As much as I love the coming onslaught of electric cars, they use lots of materials that currently have almost no recycling infrastructure — especially when it comes to their batteries. The numbers vary by the type of lithium-ion battery used, but on average, for every 100 miles of pure-electric range, a lithium-ion battery needs to contain about 15 pounds of lithium.
Although the developed world has had robust systems in place for a long time to deal with the recycling of lead-acid batteries (in the U.S. more than 95% of battery lead gets recycled), the lithium-ion battery has a long way to go to catch up. Granted, lithium-ion batteries are not nearly as toxic as lead-acid batteries and so the urgency of developing a recycling infrastructure is virtually non-existent. In fact, lithium-ion batteries are classified by the U.S. government as non-toxic and “safe” to throw away in the regular trash.
This is what the electric version of a Ford Mustang looks like.
The Big Three have fallen behind in the alternative-fuels race, and with two of the three bankrupt and barely clinging to life, we shouldn’t expect too much from them anytime soon. But that hasn’t stopped independant innovators from stepping away from the herd and offering their own versions of alternatively-powered production cars.
Take for example Kurt Neutgens and Travis Winkelman; while Kurt is a former Managing Engineer for the F-150 (America’s top-selling vehicle for many, many years), Travis worked for the ROUSH NASCAR team. Together, these two men took America’s iconic pony car, the Mustang, and gave it an all-new, electric heart.
The real reason we were in Warren, MI wasn’t to test-drive the Volt, but to be on hand for the grand opening of GM’s new battery testing facility. The $25 million Global Battery Systems lab is now the largest battery testing facility in the United States, and is four times larger than the company’s old lab.
GM made a strategic decision to keep battery development in-house, because it will likely be a key competitive advantage in the race to commercialize electric vehicles. The lab already employs 1,000 engineers who work on advanced battery systems like the one found the the Chevy Volt.
June 8, 2009- It was pouring rain when I arrived at GM’s Testing facility in Warren, Michigan. A crowd had already gathered inside the Alternative Energy Center which, among other things, is home to GM’s first electric car—the original model EV1 (#1).
The ghost of the EV1—a car designed and built 13 years ago—still haunts GM, though it’s both a symbol of lost opportunity and tangible proof that the company could pull off the same kind of engineering feat again. The billion-dollar Volt project is a major component of the company’s reinvention strategy, and it’s clear they aren’t pulling any punches this time.

YOKOHAMA, JAPAN- Last night at approximately 10:30 PM PST (1:30 AM EST), electric vehicle services provider Better Place will demonstrate key elements of their battery switching station technology. This is the first public exhibition of a battery switching station—which Better Place lauds as the final piece of a “total electric vehicle solution.” The company was invited by the Japanese Ministry of the Environment to set up an exhibit in Yokohama.
“Range anxiety,” as it’s called, describes the most fundamental fear expressed by would-be adopters of electric vehicles. It’s no different than the fear of driving through sparsley inhabited parts of the United States, where it’s important to know your car’s mileage and the distance to the next gas station.
It looks like Fisker, manufacturer of the world’s first ‘luxury plug-in hybrid’, has begun a small targeted TV ad campaign initially focusing on the LA area. The $87,900 Fisker Karma is scheduled for delivery to the first 1,000 owners by year’s end. See the commercial here:
The Nikkei newspaper has reported that Nissan is planning to invest a total of ¥100 billion (about $1.1 billion US) or more to manufacture lithium ion batteries.
Nissan has accelerated its plan to produce large-capacity lithium ion batteries for around 200,000 vehicles. The company is working with NEC group and plans to set up factories in Japan, Europe, and the United States. Honda is also planning on producing up to 500,000 lithium ion batteries for hybrid vehicles by mid-2010.
In this world, it’s easy to argue that one can never be too neurotic about our future, as our species has repeatedly shown a lack of foresight into the consequences of its actions. However, in this case, I must argue against his views on lithium’s sustainability. Lithium-ion batteries will only be superceded by superior technology, not by lithium shortage.
Farmers are planting corn and soybeans like crazy, turning food crops into ethanol and biodiesel. Scientists are squeezing oil out of algae while others are trying to coax hydrogen into a fuel that is easy to produce and safe to use. Still other developers are touting the battery-operated electric car, and one company is building a car that runs on compressed air.
Which system will survive? Or will we have a mixture of E85’s, biodiesel, electric, air and hydrogen fueled vehicles cramming our highways and straining the fuel delivery system infrastructure? Eventually, according to the age-old theory that the fittest shall survive, one method of moving us from point “A” to point “B” will emerge, and some folks are betting on the plug-in hybrid.
