Why Bother?

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
This week in class I read an article called “Why Bother?” an opinion piece by New York Times author Michael Pollan about why (or why not) we should care about combating climate change on an individual level, and what we could do to do so (gardening). In class, we just finished a quarter on climate change and are beginning one on urban gardening, so this article was very relevant to our in-class article. Something I found very interesting in the article was the almost dystopian mindset of the author -- this idea of the market conditioning us to be helpless and inextricably interdependent definitely rang true in many ways, but seemed to present a problem or reality for which the only real solution would be to return to the post-Neolithic Revolution model for human civilization, and moderation or compromise weren't really presented as alternatives.

Too Late?


In the article, Pollan first outlined a very familiar mindset for the average citizen -- the idea that “no matter what we do, it will only be too little too late.” This is particularly for the individual; when people contemplate going completely green, they’re dissuaded by the knowledge that really, their biking to work every day is not going to have much impact on the large scale, and anyway, the vast majority of people are doing nothing, so why should they?


Image result for climate change disbelieversThere is also the thought that our inaction thus far has already led to negative feedback loops (warming leads to melting ice caps which leads to more warming, for example), increasing the rate of change so we are no longer able to do anything to stop this cycle of climate change.


However, I feel that the latter mindset is, to some extent, just an excuse not to do anything -- after all, how do we know we can’t stop it until we’ve tried? -- and that the former, while reasonable enough, ignores an important truth. Large scale change can only be made by many small-scale changes.   


Because of this, yes, individual changes in lifestyle can create greater change. This is, in fact, the only way that greater change can happen. In fact, the issue of too-small scale may be solved by the power of behavioral chain reactions -- if enough people do it, it becomes the new normal. “No,” you might say, “if they make a law about it, then those other people might do it, not when they see me do it…” However, laws do not begin with politicians, they begin with a people’s movement of change -- therefore, for legalized change to happen, enough individuals must take personal initiative first.


What We Think vs. What We Can Do


Later in the article, Pollan quotes Wendell Berry’s statement about another main obstacle for mass action against climate change: “the split between what we think and what we do.” He’s referring to the phenomenon found in many people -- for example, they might support environmental organizations, but waste fossil fuels without a thought.


In many ways, this is a symptom of general lack of will to act. We know, in theory, that climate change is real and will have a major impact on the future, but can’t work up the motivation to actually make change in our everyday lives. Another example is food -- usually, people want to ‘eat healthily,’ and know that eating local and organic food will be better for both their body and the environment, but when it comes to paying more for organic foods or gardening themselves, they make excuses or “want to, but never get around to it.”


Cheap Energy Mindset


Another concept Berry comes up with is the idea of a “cheap energy mindset.” The cheap energy mind relies on market-based solutions, specialization, and consumerism. This mindset, as implied by the name, is made possible by cheap energy, specifically fossil fuels, because they allow us to specialize in one area of production and then delegate literally everything else to experts, as well as give monetary value to this specialize. This mindset has probably been what has allowed human civilization to reach where it is today, but Berry shows its downside.


Image result for fossil fuelsSay, for example, you’re a dentist. Your contribution to society is an important one, and you protect people from the horrors of cavities and root canals. When you were in school, you left your education to your teachers. When you want to eat, you go to a grocery store, relying on agriculture and food companies. When you’re sick, you go to a doctor. All reasonable, right? After, it’s impossible for an individual to meet all their needs as well as a number of experts in each area can. That’s how human society functions, so of course, people are okay with it. And it’s only natural to pay experts for their work. So far, the cheap energy mindset works.


But what about politics and leadership? Should people be so caught up in the efficiency of this interdependence that they barely know what their representatives in government are doing, let alone making their voice heard in the system that creates laws for our entire country? Berry says no, and that this a huge reason that mass environmental change hasn’t happened. Basically, people are waiting for change in the form of policy and law from the government -- after all, we should leave politics to the politicians and lobbying for environmental protection to the environmentalists.


Urban Garden


The article concludes with a solution to the problems it brings up - gardening. In class, as well, we’ve discussed the urban gardening, with a video from Nourish: Food + Community. Both sources conclude that urban gardening is extremely beneficial, from the individual to global level. In fact, the article says “it’s one of the most powerful things an individual can do.”


Image result for urban gardenA significant benefit of urban gardening is to the environment. Food you’ve grown yourself is the freshest and the most local food you can eat, which of course takes away from the carbon footprint of other, processed foods. Planting more plants means more carbon dioxide is taken from the air and replaced with oxygen. As well, time spent working in the garden is time not spent with fossil fuel-powered entertainment or other carbon footprint-increasing activities.

Another benefit is individual health and happiness. Gardening provides exercise and keeps you fit. It also, according to the Nourish video, fosters community by bringing neighbors, fellow gardeners, and even farmers together in backyards, community gardens, and farmer’s markets.

Automotive LiDAR Market Trends

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
Semiconductor Engineering publishes an article on automotive LiDAR market and trends. Few quotes:

"Technavio forecasts the worldwide automotive LiDAR sensors market will see a compound annual growth rate of more than 34% up to 2020. The market research firm estimates the automotive LiDAR market was worth $61.61 million in 2015, with most of the spending in the Europe/Middle East/Africa region and in the Americas.

LiDAR manufacturers are working on reducing the cost of the system by employing efficient processing techniques, and in certain cases positioning products as per customer segments. “For instance, the price of the Velodyne LiDAR unit that is used on Google’s self-driving car is a 64-beam Velodyne HDL- 64E priced at $80,000,”
[Technavio analyst Siddharth] Jaiswal said. “Velodyne also offers 32-beam and 16-beam LiDAR units at $40,000 and $8,000 respectively, which can be used for economical projects. We expect LiDAR technology to follow a similar path of ‘radar’ in the automotive industry, where cost played a crucial role in market adoption. Hence cost is a key focus area for the players.”

LiDAR price trend to 2020, according to Technavio

Yole Developpement analyst Pierre "Cambou noted there are different approaches to autonomous driving, and LiDAR isn’t essential to all of them. “LiDAR is a fundamental piece of equipment for autonomous vehicles, which I would rather call robotic vehicles. There will be many levels of autonomy. LiDAR might be necessary for city autonomous emergency braking, probably in conjunction with radars and cameras. This multimodality approach is well-defined now. Nobody really questions it anymore.”

And LiDAR’s market will increase as prices drop, from about $300 million today to about $600 million over the next five years. “Today there are three entry points in automotive: $3,000, $300, and $30,” he said. “Cameras are currently at the $30 price point and LiDAR is at $3,000. The goal for the LiDAR players is to lower the cost and reach the $300 target without sacrificing too much of the performance. We will see such LiDARs entering the market, probably using solid-state approaches, in the next three years.

MIT Time-Encoded Lensless Image Sensor

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
Nuit Blanche: MIT team presents an interesting concept of lensless camera in arxiv.org paper "Lensless Imaging with Compressive Ultrafast Sensing" by Guy Satat, Matthew Tancik, and Ramesh Raskar. Actually, there is a projection optics in the system, but only on the illuminator side:

"Here we present a method for lensless imaging based on compressive ultrafast sensing. Each sensor acquisition is encoded with a different illumination pattern and produces a time series where time is a function of the photon’s origin in the scene. Currently available hardware with picosecond time resolution enables time tagging photons as they arrive to an omnidirectional sensor. This allows lensless imaging with significantly fewer patterns compared to regular single pixel imaging. To that end, we develop a framework for designing lensless imaging systems that use ultrafast detectors."

Automotive LiDAR Testing Facility

online engineering degree/engineering degree online/online engineering courses/engineering technology online/engineering courses online/engineering technician degree online/online engineering technology/electronic engineering online
Self Driving Track Days: While today's automotive LiDARs and Radars are still unable to provide a required 300-500m range, the autonomous driving algorithms need to be tested and ready for the future fully-capable LiDARs. The UK company offers a solution:

Babbacombe Model Village (www.model-village.co.uk), in Torbay, Devon, has joined forces with a driverless technology training startup in an innovative bid for grant funding from the UK Government.

The funding will be used to upgrade the road infrastructure at Babbacombe Model Village, to provide facilities to test driverless vehicle technology, as well as provide charging facilities for companies also developing small low-carbon vehicles.

“The biggest benefit”, says General Manager Simon Wills, “is that we can offer everything that the big test facilities can offer, but at 1/12th of the cost… that’s great for all the companies working on the technology, but it’s also great news for the taxpayer, and could really help us attract business from overseas.”

The Model Village, which has stood for more than half a century, boasts more than 400 buildings, and includes village and city settings, shopping areas and a variety of types of public transport in a small space.

Alex Lawrence-Berkeley, of driverless technology training company Self Driving Track Days (www.selfdrivingtrackdays.com), said he was excited about the project’s potential. “What most people across the industry recognise is that developing, and more importantly testing, driverless vehicle technology is really complicated.”

“We regularly work with companies developing technologies used in driverless cars around the world through our vehicle perception training and events, and those companies are crying out for a lower-cost approach. The great thing about a lot of this technology is a considerable percentage of it can be developed and tested on scale-model vehicles.”

“UK government is investing heavily in this area, so we are really pleased to be able to help the taxpayer achieve the best possible value for money by taking a fresh approach.”
