I love solar, but this water splitting cell depletes over time (6 hr half life apparently) due to necessary oxidation, and must be refurbished or replaced. Your solar cell will in theory last indefinitly. Accounting for the energy input in

Yup, like the article notes, we use these on ships where there are often times when you need to transport large pallets of material through a maze of passages and you often don't have enough reserved deck space to accommodate the turni

Thanks - interesting. I know traffic pattern/flow models and studies can be extremely complex. However, from the perspective of a 'dumb' commuter, it seems like the investment in smarter traffic signals would be offset by glo

At 5AM, as I sit waiting for a traffic light on a deserted stretch of road during my morning commute, glaring tempestuously at the nearby redlight camera, I wonder how we've gotten to driverless cars before getting to 'smart'

I'm all for polution taxing, fines and even shutdowns. I actually find planned polution regulations to be far too lenient. However, as an engineer with the power to change affect a piece of machinery's design, I don't have to

In my profession (Marine Engineering; ship design), there is a large push to convert from diesel to cleaner fuels (e.g. LNG) due to International Maritime Organization (IMO) tiered emission regulations. LNG has a cost on par with diesel, so

Just think of it this way: all natural light (i.e. the typical incoherent light you see reflected or emitted off of surfaces in your environment) emit wavefronts that eminate spherically from each reflection (or emission) point. As such, th

I don't follow. The second law of thermodynamics doesn't say anything about the specific efficiency limits of an energy conversion or storage system. Ideal reversible systems can maintain entropy if fully isolated (e.g. insulated)

First, I didn't say anything about 'proving a hypothesis'. Instead, I described testing a hypothesis. State a hypothesis, test, evaluate the results and draw a conclusion. What you do with the results of the conclusions is up
