Electric Vehicles

Brainstorm Project

The operation and maintenance (O&M) cost of solar-power plants is very low compared to that of fossil-fuelled power plants in general, and this has had a significant impact on the energy market in some regions (such as Texas, United States). The article pertains to that effect and how it could apply to solar-powered planes (especially passenger jets).

Solar-powered planes (which are electric) don't require fuel (unless they're hybrids), therefore, the only other recurrent cost incurred by the planes is maintenance (apart from employee wages and salaries). Longer trips increase fuel consumption as well as wear-and-tear on traditional fossil-fuelled jets, so longer trips tend to attract a higher fee.

My Theory

The distance of a given flight in a solar-powered plane could affect the cost of travel far less than it would in a fossil-fuelled one due to the lack of a fuel cost. Only the maintenance cost, as well as the working hours of flight attendants and pilots would be increased.

I should note that airlines might still set airfare based on distance.

Potential Implications

The cost of fuel affects our decisions profoundly in multiple ways. We can't work too far away from home, or regularly shop at distant malls/plazas. We can't just casually fly to Australia or Europe for a meeting, as that wouldn't be feasible for most people.

This means that if the non-existent fuel cost of solar-powered planes influenced airfares as much as it could, the cost gap between long and short-distance trips would shrink substantially. If airfares aren't too high, people could end up making far more trips around the world to countries that they would otherwise have never seen in their lifetime (for example: More Americans may visit Australia, Korea, New Zealand, and other geographically distant countries), increasing the likelihood of international business ventures, tourism, greater family unit, and even the creation of new families internationally.

This is a purely theoretical article forecasting what the future of aviation may have in store for us. This article is apart of Kompulsa's Brainstorm Project, which aims to spark discussions on important issues we all face today. Feel free to leave a comment below.

Matt Farah and Zack Klapman of The Smoking Tire went on an electric car test drive to compare the value of the Chevrolet Volt and Cadillac ELR. Zach Klapman drove the Cadillac ELR, and Matt Farah drove the Chevy Volt.

Unsurprisingly, the ELR was found to be more pleasant overall, but the reviewers were disappointed in its value. They agreed that $50,000 would be a much better price for the Cadillac ELR (where value is concerned). There is an enormous price difference of $40,815 between these two electric vehicles. The Chevy Volt MSRP is $34,185, and the Cadillac ELR is $75,000 (as of April 2014 for the base models).

GM-Volt.com asked if this makes me happy I have a Volt, or if I wished for an ELR. If I had a Volt, my answer would be the former.

Panasonic, a major manufacturer of batteries, is hesitant to join Tesla Motors' 'Gigafactory' project, because it would raise investment risks, according to Panasonic's CEO Kazuhiro Tsuga.

“Our approach is to make investments step by step,” Tsuga said yesterday. “Elon plans to produce more affordable models besides Model S, and I understand his thinking and would like to cooperate as much as we can. But the investment risk is definitely larger.”

I don't blame them for being cautious, as this is a very large project. It costs $5 billion! (Tesla already raised $2 billion). On the other hand, sometimes big risks result in big rewards.

If this project succeeds as Elon Musk hopes it will, it could reduce lithium-ion battery manufacturing costs, making them more feasible for electric vehicles and home energy storage. It would also enable Tesla to manufacture hundreds of thousands of electric vehicles annually. To top it off, the success of this project could provide peace-of-mind to others who are interested in pursuing similar projects, leading to more large-scale factories that produce low-cost lithium-ion batteries.

Those are big rewards!

Autonomous cars open a window of opportunity for amputees, people who suffer from visual impairment, Parkinson's disease, and any other condition that could have an effect on their safety, such as severe cases of ADHD.

It enables them to get around privately without soliciting lifts. That's a godsend, but how is this related to energy or science?

Autonomous vehicles offer the ability to avoid the consequences of typical driving habits, such as reduced fuel efficiency, which is caused by frequent, sudden acceleration, sudden braking, and speeding.

Implications Of Autonomous Vehicles For Electric Propulsion

The electrification of automobiles is impeded by the short range of electric vehicles. Therefore, the improved efficiency achieved by autonomous vehicles (especially due to the fact that they don't speed) can help to conserve range. As a matter of fact, it can substantially improve average range, making electric vehicles a far more viable and attractive option than they ever have been.

Autonomous vehicles can also be equipped with smaller battery banks and achieve the same range that today's electric cars do, reducing their cost.

The City of Fremont has made a number of local headlines this month for reports on the high number of electric vehicle owners living within its boundaries. With a population of 221,986, Fremont holds 14.3 percent of Alameda County’s 1,554,720 residents.1 But with 3,870 electric vehicle rebates issued in Alameda County since 2010 under the California Clean Vehicle Rebate Program, Fremont, with its 1,143 rebates to date, represents 29.4 percent of all-electric vehicles owned within the County.2

Fremont's EV Rebated By Month

The reason for the heightened media attention is that many people were surprised that this southern Alameda County suburb could be “the East Bay’s epicenter for electric vehicles,” questioning, “What makes it so special?” The news of increasing EV ownership in Fremont, however, is less of a surprise to those responsible for City development. As the City’s deputy director of Community Development, Dan Schoenholz, stated when pointing out that a slightly larger number of electric vehicle rebates had been issued in Fremont than in San Francisco, “San Francisco has the reputation for being a super-green city, but this shows that Fremont is quietly pushing the envelope.”

The story, in fact, fits nicely into the future vision that the City has created for itself. This is a future of sustainable urbanism, one in which Fremont has evolved beyond its early agricultural roots and post-war suburban sprawl into a center for clean technology, a mecca of cultural diversity, and the home of eco-conscious citizens. Beginning in 2011 with the City’s award-winning General Plan that strategically positioned “Sustainability” as the opening chapter for its 2030 vision, and gaining momentum with the adoption of its Climate Action Plan in 2012 to reduce greenhouse gas (GHG) emissions by 25 percent by the year 2020, the City of Fremont continues to challenge the conventional model of development with an alternative one that places the health and well-being of future generations at the forefront of policy-making.

The e-NV200 — essentially a compact commercial electric van inspired by the LEAF — was recently unveiled by Nissan. The electric van will be only the second battery-electric vehicle to feature into Nissan’s global line-up — the first being, of course, the highly successful LEAF.

The general idea behind the vehicle was to combine all the best qualities of the LEAF with the cargo capacity of the NV200, creating an effective electric transportation solution for delivery services/small businesses (or for people who have too many kids).

If you’re already familiar with the gas-powered NV200, then you may have some idea in your mind already, but the e-NV200 is actually quite a different vehicle. It has been the subject of a full engineering development program, as if it were being designed from the ground up.

At the time of release in June, there will be two versions available — the Combi (a van), and the more luxurious Evalia, a five-seater. Nissan hasn’t revealed the pricing information for either versions yet.

Green Car Congress provides further information:

The battery can be recharged overnight using a domestic 16-amp single-phase 3.3 kW supply which reduces to four hours if a 6.6 kW/32-amp supply is used. A dedicated CHAdeMO DC 50 kW quick charger can recharge the battery from 0-80 percent in 30 minutes or less if the battery is already partially charged.

The instant torque delivery typical of an electric vehicle means the battery-powered version accelerates faster than its conventional cousin: its 0-100 km/h time is quicker than the 1.5 dCi-powered NV200, with final figures to be confirmed later this year.

Another drivetrain change over LEAF determined by e-NV200’s likely usage pattern is a new braking system with a higher regenerative capacity. This takes advantage of the vehicle’s typical stop/start city driving modes, while Hill Start Assist is fitted as standard, holding the vehicle for two seconds after the footbrake is released to allow smooth starting.

People have driven more than 1 billion miles in Tesla, Nissan Leaf, and Chevy Volt electric vehicles. This signifies that the public, and the electric vehicle manufacturers now have over 1 billion miles of EV driving experience and test data.

This is critical to the electrification of the automobile, as early adopters are putting EVs to the test. When they fail, manufacturers learn of the mistakes they made, and enhance their electric vehicle designs further.

This also entails that many more than the billion people have been exposed to electric vehicles (due to the fact that they give their friends lifts and test drives in their electric vehicles).

Early adopters got today's big industries where they are, and they are doing the same for the EV industry.
