CADMAN-LT. I am always appalled at how elementary writing and communication skills are for recent graduates. Many of the engineers coming from reputable accreted schools can't put together a sentence, much less a report that makes sense. When I worked for a Fortune 500 company, we had a very active co-op program. I was one of the engineers chosen to "mentor" these young engineers. That meant reviewing their reports. You would not believe how frequently I had to re-write their documents. There were several engineers, with English as their primary language, that could not construct a simple sentence. I have no idea as to what they are teaching these kids now days. Their technical skills were very sharp but communication really needed work. Very embarrassing.
I clicked the link for The Copenhagen Wheel, because the article referred to it as the "wireless" wheel which confused me. The wireless descriptor means simply that it has a transceiver to link to your smartphone where you download an App and adjust the wheel's torque and power setting based on terrain.
This device is a very sophisticated, MIT developed, electromechanical engine, which works as a 'drop-in' replacement of your existing bike Rear wheel. Pretty ingenious, in its construction, efficiency, and retrofitability. At $800 its targeted at European commuters, over expensive gasoline for daily use. https://www.superpedestrian.com/ is currently accepting Pre-Orders.
Second to that, it's not alone in its niche marketplace. The Electron Wheel also uses a motor concealed in the Front Wheel, which drops into most 26" bikes in only 30 seconds. Entirely battery powered, it uses sensors to determine how much boost is given to the rider, based on grade & terrain. http://www.electronwheel.com/ is priced at $999 and is available now.
What is educational is that most of the engineering type job postings that I have seen in the past ten years specify "excellent communications skills", which is a hint that not only are they important, but that they are quite important. I have lamented in quite a few postings in the past that the modern word processing systems and packages will help any fool to produce a reasonably intelligent looking document. We have lost one quick way of sorting out the junk. The unintended consequences of an invention that was intended to benefit all are with us again.
While my style of writing may not please everybody, the large number of technical documents have been praised by those who need to use them.
Honestly. Almost all of the posts I read (excluding here) are misspelled and the grammar is horrible. If this is the future how will they communicate?
Don't quote me on this, but if you have seen the Dragon Naturally Speaking commercial......that kid says....I can't put word to paper, but with this I just talk to it and it does it for me......really...that kid needs help! not a program! Get him a tutor. That commercial sickens me. Ohh you're stupid, here, you don't have to know how to write!....no way!
To be honest. I do not have any kids. I can say I would be scared to have any semi young ones in this day. With all of the LOL and stuff, do they even know how to write correctly. Part of engineering is communication. I can't lol to my boss! My friends have kids and I see it. I fear for how they communicate in the future. Point is, there is more to engineering than just math.
Charles, I understand what you mean. I myself excelled at math. I was mechanically...ok. I wasn't great. I took some time off after college and became a machinist. I learned a lot. I now how have the best of both of those worlds. Oh I became a CAD drafter too. It all helps. They all play nicely together.
Where is the boy box? They don't get one? I think they all need pushed into the field.
I find it difficult to imagine that a system can charge the batteries with enough energy to deliver useful power without being quite a burden the rest of the time. As I look at the photo I find that it certainly does not give much clue about how the system is able to deliver much torque. While using a smart phone application to unlock a bike does sound useful, that also sounds like a way to be stranded if the phone battery, or the phone, dies. And the amount of actual "lock" that it can deliver is probably limited to the rear wheel.
Bikes typically have a minimum of ten gear ratios which are adequate for most urban riding, except for climbing stairs. So really, except for long rides, a small battery assist package does not appear to deliver benefit equal to the cost.
Of course, for most of the last few years I rode a few miles every day, which probably affects my opinion of when some assistance is needed.
Although plastics make up only about 11% of all US municipal solid waste, many are actually more energy-dense than coal. Converting these non-recycled plastics into energy with existing technologies could reduce US coal consumption, as well as boost domestic energy reserves, says a new study.
