Two Electric Car Teams Vying To Be The First To Circle The World (via Gas 2.0)
The older I get, the more I subscribe to certain truisms, and it seems to me that truth really is stranger than fiction. Over a hundred years ago, Jules Verne penned "Around The World In 80 Days", a story about a wager to travel the width of the world in the ascribed amount of time. Electric car…

Paintable and printable solar cells are lowering the cost of solar power, and now researchers at Rice University have come up with a battery to match. They have developed a new paintable lithium-ion battery that can be applied to almost anything from beer mugs and bathroom tiles to plastics, glass and steel. Since the new battery can be charged with a small solar cell, the team envisions low cost, paint-on devices that can harvest solar energy and store it for later use, too.
Painting with Batteries
The new technology is based on separating the components of the battery into five paintable solutions, like a high tech paint-by-numbers kit.
The positive current collector is based on carbon nanotubes, and the cathode contains lithium cobalt oxide. A third component is a polymer separator made with a proprietary resin called Kynar Flex (made by the company Arkema).
The anode contains lithium titanium oxide, and the negative current collector is based on an off-the-shelf copper paint.
That sounds simple enough, but the team found that getting the right properties to make the separator stick on was the tricky part.
Low Cost Solar Batteries on the Way
The team really did test the paint-on battery on a beer stein along with other common objects such as bathroom tiles, and they were able to power a light with it after charging the battery on either white light or the lab current.
The research-scale product was hand painted, but lead author and researcher Neelam Singh points out that it would be fairly easy to scale up the technology to commonly used industrial spray-painting techniques.
One key to lowering the cost of the technology will be to develop paintable solutions that can be applied in open conditions, rather than relying on vacuum deposition technology or other intensely controlled environments.
The New Energy Aesthetic
If solar inks and other liquid solar power technologies develop apace with paintable batteries, it’s likely to lead to a new generation of options for architecture, interior design and product design, in which objects and surfaces can be used to harvest energy, store it and power lights and other devices.
The possibilities really multiply when combined with ultra-efficient lighting, namely OLED (organic light emitting diode) technology, which enables the creation of entire light-integrated surfaces.

Leadership from the Obama Administration has set the federal government on the right track in terms of energy policy, engaging state and local government, private sector businesses and local public interest groups in efforts to boost energy efficiency and clean energy use. Two announcements this week drive the point home.
On June 26, the Obama administration announced that 36 additional states, local governments and school districts have joined the President’s “Better Buildings Challenge.” With nearly 300 million square feet of of building space in their care, joining the program not only helps insulate the owners of these buildings from high and volatile fossil fuel energy costs, it opens up the likelihood of putting thousands to work conducting energy audits and energy efficiency upgrades.
Joining the Better Buildings Challenge also lays the foundation for many years’ worth of work that will not only reduce energy consumption and wasted energy, but will reduce CO2 and greenhouse gas emissions and other forms of environmental pollution.
Further supporting Better Buildings Challenge members by streamlining federal administration related to the program, the Treasury Dept. is providing new tax guidance that will make it easier for state and local governments to gain access to more than $2 billion in existing low-cost financing for energy efficiency and renewable energy programs, according to the US DoE Energy Efficiency and Renewable Energy (EERE) news release.
Fostering Clean Energy Innovation
The Obama Administration announced another noteworthy piece of clean energy/energy efficiency news this week. On June 27, Energy Secretary Steven Chu announced the DoE is awarding more than $102 million in grants to 104 small businesses across the country to help advance clean energy innovation. The clean energy innovation grants will span small businesses in 26 states, “helping to continue to develop promising technologies with a strong potential for commercialization and job creation.”
Small businesses play a big role in the US economy. They created 64% of total net new jobs– 14.5 million in absolute terms– in the US between 1993 and 2008. Moreover, nearly 40% of the US science and engineering workforce are employed in small businesses, the EERE notes.
This week’s 104 grant award winners are in the so-called “Phase II” stage of clean energy innovation, at a point where they are ready to “build on the conceptual work undertaken in Phase I and pursue next steps in bringing the technologies to market,” the EERE press release explains. Phase II grants can total as high as $1 million for work spanning more than two years. Phase I grants can total as high as $150,000.
This week’s Phase II awards span a variety of renewable and clean energy technology, ranging from large wind turbine towers and particle accelerators for medical applications to more energy-efficient data centers and advanced imaging and X-ray technologies. Details of the 104 Phase II award-winning projects are available on the DoE Office of Science website.

The big-screen television is the pride and joy of many households the world over — poor and less so — and as the years go by, those same huge-ass televisions are getting more and more energy efficient. According to the latest rankings of the 10 efficiency leaders in three size categories, even the largest model is operating on only 64 watts. That’s less than the typical incandescent lightbulb.
The stats come courtesy of nonprofit TopTen USA, which ranked the 10 most efficient televisions in three categories: small-, medium-, and large-sized TVs. Considering that televisions in the average US household are on for 5 hours every day, it’s good to know which TV is harming the environment the least.
“Choosing the best of the best matters,” says Norman Dean, Executive Director of TopTen USA. “Few consumers realize that there is a wide range of power use even among the relatively efficient televisions that qualify for the Energy Star label.”
Let’s look at the 60-inch Sharp LC-60LE847. It’s ranked second on the list of TopTen Large TVs for June 2012, is one of 59 Energy Star–qualified televisions that size, and uses an estimated 104.5 kilowatt hours of energy each year.
That’s almost half the number of other Energy Star–qualified, 60-inch models which are using as much as 195 kilowatt hours of energy a year.
Samsung led the way with 12 of the 31 televisions on the three lists, including the top 3 places on the ‘Large TVs’ list, which is a TV of 46 inches in size or greater. Magnavox topped the ‘Small TVs’ list, which is for 31-inch TVs and smaller, with Philips, Panasonic, LG, Insignia, and Sansui also nabbing good places amongst the list.
For more information, including the methodology behind the assessment, head on over to the TopTen website.

Sol Invictus, the Invincible Sun, was the roman sun god and patron of the late emperors. While the sun is without doubt invincible and, in human terms, a never-ending source of energy, the pro-solar energy policy of Germany has come under heavy attack this year. As a result, the German government has passed a law that will cut incentives for solar power, the solar feed-in tariff, by up to 20% today.
So, how is a massive cut for in incentives a win for the invincible sun? Well, here is my take on the events and why hearing "Germany decided to cut support for solar" is actually a victory in an ugly battle that might lead to global change… but that’s perhaps a bit too dramatic.
Once Upon a Time On a Battlefield
Attacks on the pro-solar policy framework of Germany are nothing new. They are actually more of a recurring event that happens every time the "Renewable Energy Act" gets reformed or whenever solar power installations break a record. All of this started with the stark opposition of the current government coalition against the "German Renewable Energy Act" back in the year 2000, when those parties weren’t in power. They especially disliked the concept of providing independent investors with a technology-specific feed-in tariff that was high enough to turn a profit if investors made wise choices when developing their project. Back then, Angela Merkel’s conservative party was basically fundamentally opposed to the the core principle behind the success of the “Renewable Energy Act.”
At the start and until 2003/04, this uncapped and guaranteed possibility to turn a profit with clean energy investments did not apply to solar power because it did still received subsidies in the form of a credit incentive program — the 100,000 roof program aiming for 350 MW of solar power. Disgruntled by the reality that the Renewable Energy Act has proven to be more successful and efficient than portfolio-standards/quota-systems, the opponents focused their criticism on the support of photovoltaic energy use in Germany… something that was a pure waste of money and would never accomplish anything according to their opinion. In 2009, the opposition parties of the early 2000s managed to win a majority in the federal election and form a government coalition. The parties are Angela Merkel’s conservative Christian Democrats and the free-market and business-friendly Liberal Democrats.
Here We Are Again
This February, things turned very ugly though, when the economics ministry (responsible for regulating conventional energy markets) and the environment ministry (responsible for renewable energy sources) proposed a rapidly drafted revision to the renewable energy act at a joint press conference. This draft was proposed just 6 weeks after another revision of the law went into force on January 1, 2012. The content of the proposal was so radical that it was soon dubbed "The Solar Phase-out Law," or even the beginning of a rollback of the "Energiewende" and nuclear phase-out.
In the eyes of the economics minister Philipp Rösler (the head of the free-market oriented "Liberal Democratic Party" and the vice-chancellor), a rapid revision was necessary due to the "out of control" growth of solar power capacity in 2011. Soon the usual bunch of anti-renewable energy vultures within the conservative party joined the criticism and voiced their support for rapid cuts to "contain solar energy." They are a relatively powerful group within Angela Merkel’s conservative party and have close ties to powerful industry groups and the conventional power and energy corporations. This anti-solar coalition of politicians within the government and vested economic interests in the private sector was also heavily disgruntled by the decision of its party leadership to speed up the phase-out of nuclear power a few months before. It's safe to say that the situation was serious and more than dangerous for effective pro-renewable policy. Especially since pro-renewable supporters are a minority within the government, and the public was distracted by the looming European debt crisis.
The original "Solar Phase-Out Law" proposal included a wide range of changes that were officially focused on reducing incentives to install more solar power. In reality, it was the strongest attack on the fabric of the successful "German Renewable Energy Act" since it was passed into law in 2000. Among the gems of the ministries’ wish list were harsh 30-40% cuts to feed in tariff rates, the ability to further adjust feed-in-tariff rates by ministerial decree without consulting the parliament and exempting 10-20% of the generated electricity from receiving feed-in tariff payments. To make things even worse, the proposed changes should take effect retroactively* only 2 weeks after the proposal was made. (*Retroactively because it was obvious that the legislative process to pass the law would take longer than 2 weeks.)
From Proposal to Legislation
What followed was a legislative dispute that took more than 4 months and was accompanied by a massive anti-renewable/anti-solar campaign throughout many media outlets that aimed at reducing the popularity of solar power among the public. But there were also pro-renewable/pro-solar voices in the media and even mass demonstration by the solar industry together with unions and activists.
The legislative process and dispute already started within the administration then raged on among the government coalition within the parliament. An altered version was then debated on the floor of the Bundestag (the German parliament), and finally at the Bundesrat (the upper house of parliament), where representatives of the state governments had to vote on an already heavily altered and softened version of the original proposal. But despite massive pressure by the federal government on the states to adopt the law, the events took a decisive turn as the state representatives voted to block the anti-solar legislation with more than two-thirds of the votes in a united effort across party lines.
This massive "NO" by the states forced the federal government to discuss a resolution of the conflict with a so-called "Mediation Committee" in accordance to the German constitution. One month later, and after a new environment minister was appointed by Angela Merkel just days after the Bundesrat decision, the committee reached an agreement last night which was passed by the Bundestag today.
With the agreement between the states and the federal government, the political dispute that dragged on for four long months and kept the entire German solar industry with more than 100,000 employees in limbo has finally come to an end.
Here is an overview of the changes, cuts, and the new solar FiT rates:
As you can see, the final results of this battle are not perfect, but they are world’s apart from what the anti-solar coalition had wished for. In fact, the most likely result will be a continuation of the solar power boom here in Germany for the years to come. Many analysts actually predict that the 52 GW mark could be reached as early as 2015/16, which would be a doubling of 40% of the solar capacity of the world within 3-4 years. While more solar power is awesome, there are too many ifs and hows to be really happy about the outcome. Furthermore, the discussion remains focused on how to integrate renewables into the “market” instead of the other way around. The big question is how to integrate the existing fossil power plants into a renewable-energy-dominated power system, not the other way around.
The Moral of the Story
Since the main purpose of this entire circus started by anti-solar members of the administration and government coalition was to prevent the further expansion of solar energy by rapid action and changing the rules in favor of the big energy corporations, this decision is more than a defeat for them.
Sol Invictus, the invincible sun, rules supreme but somewhat battered. All the gigawatts that will now be installed are important steps toward establishing a decentralized renewable energy system. Photovoltaic power is back on track to achieve the unthinkable in Germany. It could break the baseload-centric conventional fossil power system for the first time since the age of industrialization began.
Furthermore photovoltaic power might become the cheapest source of energy sooner than many people can imagine.
But before that day will come, there will most definatly be another attack on solar power… as it is tradition apparently. We’ll see when and how that inevitable next attack happens. 10 GW of new solar capacity might be a good reason to bring the circus back in down.
