I would be curious to know if some kind of synthetic oil would have worked better in this situation, maybe we should get out of this, that oil may not be the best solution for lubricating, or that explosions and pistons are not the best way to propel things at this scale.
You are absolutely right, and the solution with cross-hatching of the walls of the chambers did not go unnoticed, and may serve some purpose in the future. My point was simply that the time and money could have been spent on something more productive and gained a better insight into something. This is old technology and certainly not something they were modeling to find a better way to do something. They were just having fun, and that's ok, because many advances in technology happen when trying to accomplish a different goal.
The purpose is for model vehicles. I have seen many scale model jets powered by real jets engines, scaled down. People who have the money to do this type of thing do it because they find it interesting and a challenge. I have watched these jets flown remotely at real speeds of 200MPH. Now that is a feat. Is it practical or important? Well, frankly no. Is it interesting and a challenge. Well, yes. Just discovering the issue with the oil is interesting. Who knows, there might even be a practical use for this knowledge in the future.
I can't think of any way to justify the time and effort put into this engine, I'm kind of sad that I wasted the time reading this article, as are the people at the show that bothered to stop and look at it. Novelty at best. Complete waste of time at worst.
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
This year, Design News is getting a head start on the Fourth of July celebration.
