The Digital Switchover.

Not me. I almost did that a while back, but no. Not me.

Television.

Normally I wouldn't write about it. A digital television standard is long overdue and in the end this will be a good thing. When you compare Analog vs Digital, there are many more benefits on the digital side of things: lower power for transmission, better bandwidth of signal, more bandwidth usage over the spectrum. All of these are good things. I can even talk about how those digital signals still have lots of analog components as they're transmitted over the airwaves: multipath, signal loss, power calculation, reception problems, etc.

But no. I'd rather point something else out:

Technology adoption is driven by human nature. It must be adopted before it can help people.

Sure, the digital signals will be great. High Definition pictures and you don't have to give a dime to those lovely cable companies. Lower power generation required to transmit the signals will help save the environment by lowering the carbon footprint. But until the switch actually happens (today...maybe), no one gets the benefits. The switchover has been delayed to now from this past February. Lawmakers deemed the country unready to make the switchover at that time. I mean, if people can't watch TV, how will the politicians get their message out to the masses?

No matter how many new devices are introduced into the marketplace and no matter how available they make DTV switcher boxes, people still will not change until pushed. They will not go out and get the digital box or call their local politician until one day they turn on their television and the signal is not there. That is what will drive the final changeover. I wouldn't be surprised if we saw a little bit more leeway from politicians before stations are officially told to shut off the analog transmitters.

This problem isn't exclusive to television. This has happened for the past 30 years in conservation and renewable energy.  Regardless of how many times climate change experts point out we're killing the planet, nothing moves until there is a scare that oil is running out (it is) or natural gas won't always be available (it won't) or coal is filthy (it is) or the power just goes out. Then people change their tune; they change gears and start thinking about buying that solar array or that home wind turbine. They start recycling again because they think it will start to help (it will, but what about the past 10 years of bottles you put in the landfill?). But the thing is, you need to think about buying the solar cells now, when there isn't a 6 month backlog of installation requests and prices are jacked up due to demand. And Solar might even already be an affordable option for you.

I'm sure people will say there's an economic aspect of it for DTV and that the people that use analog signals the most can't afford the converter boxes. Perhaps that has some truth to it. But the point remains that no matter the technology, until that last group resistant or indifferent to change decides to go out and do something about it, those people can't be helped.

What about you? Have you made the switchover yet? If not, why? Leave a note in the comments.

Engineering parents don't tell their kids to study engineering for lots of reasons. One of the biggest reasons is that they don't understand what engineers do. There aren't really any television shows that explain it. It's not sexy enough for Hollywood. There really just isn't much information to the general public unless they are looking for it. I know I didn't have much access to this info before seeking it out. And I know how it feels to have people nicely shake their heads and smile when I explain what I do at parties.

So I've decided part 2 of the "What the world needs" series here will be more references to engineering in popular culture. It can be advertising in any form (as in "Any press is good press"). People talking about engineering and what the heck they do might inspire some to go out and find out more. They might start reading blogs about engineering (dream on Chris). How might this stuff get into the mainstream? Well, comics of course! And no, not Dilbert. I choose XKCD for my mainstream weapon of choice. If you have never read the site, I insist that you go there immediately and read as many backlogged comics as possible. The author has a great grasp of mathematics, science, love and life. Bringing focus onto engineering/science/nerdy culture can only do good things for the profession and encouraging kids to explore if they would enjoy the work.

A note about the comics on XKCD, always be sure to mouse over the comics to get the "hidden message" which extends the sarcasm and awesomeness of the comic itself. Without further ado, my new favorite XKCD:

(If you don't quite get it, current is defined in the opposite direction of how electrons actually flow thanks to Ben Franklin. This can get REALLY confusing when working with electronics, but eventually you learn to deal with it. Eventually.)

A quick note to share what I heard this morning on NPR and thought is relevant to...well...me really. But you too if you live in Cleveland and are interested in renewable energy.

Frank Jackson, mayor of Cleveland, is in Germany this week, drumming up business to move to the US, specifically Cleveland and most specifically, in renewable energy. This is great news for the region because it could help bring back some manufacturing jobs (especially skilled manufacturing, as required by solar). Aside from more reasonable wages the US can offer  to businesses thanks to the recession we're currently in, Jackson is pushing the research capabilities at Case Western Reserve University and other local schools. He is also citing Cleveland's strong infrastructure that could be critical to moving product within this country by rail, truck or plane. Add to that the cultural amenities of the region and it starts to look like many of the reasons I moved back here. The trip was financed by the Cleveland Foundation, a great local charity that pushes for more development in the region.

So far, I have seen news that IBC Solar is planning to move their US headquarters to Cleveland, after rejecting California and NJ.  However, a deciding factor will be if Ohio pushes for using renewables to provide some portion of power to utility customers, as many other states have started mandating. Remember, simple solar panels are not the only options here; solar concentrators and wind power are on the menu also, with wind being a very likely candidate due to great northern winters reducing the amount of total sunlight and the potential of strong winds on Lake Erie.

While I remain cautiously optimistic about the potential of more renewable energy moving to Cleveland, I think that it is wonderful that Frank Jackson is out pushing for better development of this industry in Cleveland; I hope these efforts will continue here and will be pushed as a national agenda by the new administration. Are you in Cleveland? Interested in renewable energy? Let me know in the comments section or shoot me an email.

I wrote last week about Barack Obama further laying out his plans for renewable energy. He states in that video that he plans to invest $15 Billion or more in renewable energy each year. My question is, what can we start doing now? In order for him and the renewable energy community to hit the ground running on Jan 20th, we need to start planning some actions for the new administrations (with or without funding).

1. Education -- Without a new crop of able young engineers, we won't get far. So how do you get involved in helping to make this a reality? Follow my volunteer idea and go to middle- and high-schools and share what it's like to be an engineer with young people. Even better, I recently found out that I was right in thinking I was not original...there are many programs in place to allow engineers to easily reach out to their communities. The one I am currently considering is the New Faces of Engineering Road Show, hosted by the Cleveland Engineering Society. They travel to schools and promote engineering and science to young students, basically the exact thing I wanted to do.
2. Conserve -- The best way that individuals can help on a daily basis is to conserve, in general. Use less utilities (turn off your lights, turn down your heat), recycle your recyclables, carpool to work
3. Stay involved -- This year has shown young people actually can make a difference in elections and in general. This is due to the extreme influence of social media and how it connects people online and throughout the world. Now use that power to go out and influence individuals and corporations that a green economy will benefit all Americans (and the world).
4. Consider alternative and renewable energies -- Black silicon or not, photovoltaic (PV) cells are still expensive. However, there are simpler methods, such as corn stoves, which have lower environmental impact and are definitely renewable year after year.
5. Keep them honest -- No matter how good their stump speeches are nor how honest they may seem, absolute power corrupts absolutely. While the checks and balances were put in place by our forefathers to keep our branches of government watching one another, the true power in oversight will come from civilian oversight. This has been further enabled by the internet in recent years and we must insist that our newly elected government officials do not take advantage of their positions for personal or nepotistic gain.
6. Join the fight -- Sure, there will be more political battles, notably with oil barons not wanting to relinquish their grasp on easy profits; but the real battle is with innovation and design challenges. Use online resources to go out and educate yourself on analog electronics. The biggest challenges will be won by the groups with the most resources. If we want a future filled with solar and wind generated power, go out and learn how to make that a reality by studying the basics.
7. Start something -- Been studying this stuff for so long that you think you have a great idea on improving an existing system (the power grid, anyone?) or developing a disruptive renewable energy technology? Go for it. In order for the green revolution to begin, America (and the rest of the world) needs entrepreneurs to step up to the plate and take risks in order to develop these emerging technologies. Do you prefer the less technical side of engineering? Pair up with the entrepreneurs. Technically minded people are just as important to take the time to introduce the new technology to the rest of the world.

Good luck President Obama. You have a huge challenge ahead of you, a huge wreckage behind you and a huge nation standing and waiting for you to wave the green flag. Let's all try and toe the line as soon as we can.

I take a personal interest in Barack Obama's new plan to increase investment in renewable energy technologies, as I think and hope my long-term plan of working on renewable energies will come to fruition.

Skip to 9:38 to hear about his plans for renewable energy

I don't seek to point out any political messages other than to focus on his determination to make renewables a viable part of the American economy, much like Thomas Friedman points out in Hot, Flat & Crowded. A green revolution or economy will help to return America as an arbiter of international issues by once again showing our leadership and innovation abilities (not to mention our economic strength). While I will point out that John McCain has also shown some initiatives for renewable energy (not to mention he does not believe that drilling for oil is the only solution), I feel that his focus on nuclear as the only true long term solution in his administration would not put enough money into the hands of people that will drive the "green revolution". Given the possibility of recession in this country (or is it already here?), I believe that direct government investment in renewables will help to jump start the economy by driving job growth. And it won't just come from the presidential administration either; people in the house and senate all need to push these new green energy agendas to really allow for new legislation. Great examples of this are Alice Kryzan, running for the 26th congressional district in New York and Dan Maffei who is running for the  25th district, also in New York.

Probably the point that I would like to point out most in this video is his call upon the American people to reduce their consumption AND take personal responsibility in their lives (i.e. childhood education). Sure, we could use our innovative techniques to create energy at the cost of the environment ad nauseum. But why not instead work on power saving techniques? Why not inflate your car tires to increase gas mileage, instead of pushing for faster ramp ups of offshore drilling? Why not tell people to turn off their lights, recycle their garbage, stop watering their lawns and driving gas-guzzling cars? Because it's tough telling people that stuff. It's not going to work at first, but it will over time, and that's why I thought this was a good video.

I always welcome comments on renewable energy, but given the touchiness of politics, please be extra gentle when commenting. What do you think of the renewable energy plan? Is it a pipe dream? Do you think there are pieces that both candidates are missing?
