Ten Things for an Engineer to consider now that summer is here

Now that summer is here...

I should caveat that a bit. Summer just started last week here in the Pacific Northwest. It's been one of the wettest and coldest springs in quite some time. I should caveat that too. "cold" here in the Pacific Northwest means like 40 degrees. I realize that some places don't really consider it to be cold unless it drops below 255.3722, but we're a little more weather intolerant than that around these parts. Now I have to back out of my recursive caveats. </CAVEAT #2> </CAVEAT #1>. That would have been much shorter in C - 22 characters shorter at just } }.

RCA12ax7_sq_arms Now that summer is here, what can an engineer do to keep productive despite all of the distractions outside? I've got a couple of suggestions. Mostly things that roll through my head when the mercury rolls up.

X - Contemplate global warming and question whether we should try to do something about it. In my mind, there is no dispute that global warming is happening. The problem is that the difference between causality and correlation has been politicized. That means that it's very difficult to find any real information that isn't biased based on someone's personal agenda. So, we have a number of questions to muse on: Is it human caused? If not, is it human exacerbated? If it's primarily human caused, is it too late to stop it? If it's primarily a natural phenomenon, should we try to mitigate it? If we try, will we just make it worse? Can we ever get past the politics and agendas and really examine all the facts using the scientific method?

IX - Decide if hybrid vehicles really help or if they are currently designed in such a way as to really help. Taking an economy box that could reasonably get 40 MPG with an efficient gas or diesel engine and simply giving it more power at the same MPG doesn't really help with the fossil fuel problem. On the other hand, if you take a large vehicle that gets 10 MPG and increase that to 15 MPG by turning the combustion engine off while stopped and using an electric motor to re-start and accelerate through the least efficient first few miles per hour could save 15 billion gallons of fuel per year (based on some quick very rough calculations). That's a lot of french fries.

VIII -Think energy storage and retrieval. Petroleum is just about the most compact energy storage medium and the most that is currently practical to use in small quantities. The problem, of course, is that it's easy to get the energy out, but it's a one way trip. We won't really replace petrol until we can find another storage medium that's at least 70% as efficient in terms of energy extraction and can be refilled just as easily.

Linux-penguin-big_origpreview VII - What about locomotion in general? The bicycle is just about the most calorically efficient method of transportation ever devised. It's use can be practical in many situations, such as cities designed to accommodate large numbers of bikes, but is woefully impractical in other situations - hills, long distances, cargo. Can we take anything from the bicycle and apply it to other forms of transportation?

VI - How can we take our economy back from the money grubbers? Profits built this country, but at various times in our history, the unrestrained pursuit of profit above all else has nearly destroyed it. It's a repeating cycle and I think that at the moment, we're in one of the eve-of-destruction points. Even in recovery, the financial institutions, to the best of my knowledge, seem to be more interesting in finding new quick-flip money making loop holes than in creating a strong foundation for the future. Teddy Roosevelt busted the big monopolies. Ten years of great depression and WWII busted the cycle a few decades after that. How can we break this cycle of ruin without a real depression and war?

V - Can we remain free in an increasingly tight surveillance society? We have technology and resources that would have made Orwell's Big Brother drool and that technology isn't going away. It will only get cheaper, smaller and more pervasive. The technology itself isn't inherently bad, but the misuse of it tends to be incredibly tempting. Being a good steward of things that can be used for good or for ill takes a lot of work and a lot of personal and group-think restraint. Are we mature enough a society to maintain our humanity in the face of such tools?

IV - What do we do about the impending loss of fun and adventurous careers like being a pilot? Knights of the air - the fighter pilot has long been the ultimate in high adrenalin jobs, but even today, outside of training, it's more button pushing than envelope pushing. It won't be long before it's all robot drones. In the civilian world, my bet is we have less than ten years before most cargo flights are unpiloted and passenger flights won't be far behind.

III - Speaking of robots, when will someone build something that's actually practical for consumers to use? I know there's the little robot vacuum, but that's just the tiniest of entry points into the consumer world. We're at 1979 in terms of the evolution of the personal computer. Let's get moving and get some real-world personal robots going.

II - What's left to put embedded computing into? Microcontrollers are into just about everything already. But there have to be a few good killer embedded applications left that we haven't run across. Figure those ones out and build another industry. Start your own company to do it and create some good jobs.

I - And, finally, where's my flying car? Okay, this one is really dream-world until we can figure out the energy storage and retrieval problem (see VIII above). If you think it's inefficient to push a car around on the ground, add fuel for lift generation into the equation. Ugh. Fix that problem Batman and then we'll be somewhere.
