He is best known for his engineering work on the TR-106 and SpaceX rocket engines. He is considered one of the world’s leading spacecraft propulsion experts and holds several United States patents for propulsion technology. Tom Mueller Engineering career Employer(s) … Continue reading →

Microscopic particles can penetrate deep into the lungs and have been linked to a wide range of serious health effects, including premature death, heart attacks, and strokes, as well as acute bronchitis and aggravated asthma among children. What is the … Continue reading →

Fortunately, most lithium-ion batteries work as intended — and don’t catch fire. Can dead lithium batteries catch fire? The amount and rate of the gas released depend on different parameters that are related to battery chemistry and the amount of … Continue reading →

Nanotechnology has direct beneficial applications for medicine and the environment, but like all technologies it may have unintended effects that can adversely impact the environment, both within the human body and within the natural ecosystem. How does nanotechnology benefit society? … Continue reading →

Do car battery terminals get hot? Car battery terminals do get hot in abnormal situations where loose connection, corrosion buildup, and incorrect cable size create resistance. Bad starter and alternator overcharging will put unnecessary stress on the battery, causing terminals … Continue reading →

When two alternators are running in parallel, both machines are connected to the supply. Both alternators produced voltage and current which gives to supply because both machines act as an alternator. Can you parallel 2 alternators? If you connect two … Continue reading →

There are other instances (not just during charging) where a LiPo Bag is essential for safety. LiPo bags are a convenient way of safeguarding your batteries during charging, transportation, and storage. If you ever leave spare batteries in the car, … Continue reading →

From its name, you may think that the Iron Man suit is made from iron but, as Tony Stark is quick to point out in the film Iron Man, the suit’s shell is made from a gold-titanium alloy. Fortunately, there … Continue reading →

Physicists May Have Discovered ‘New Force of Nature’ in LHC Experiment. The Large Hadron Collider (LHC) sparked worldwide excitement in March as particle physicists reported tantalizing evidence for new physics – potentially a new force of nature. Is there a … Continue reading →

uru metal. Norse mythology and Marvel Comics tell us that Mjolnir is composed of “uru metal,” forged ages ago by the blacksmith Etri in the heart of a dying star. Presumably uru metal is magical in nature, and thus conveys … Continue reading →

Your toy is a bit like a bridge – the electrons race around it to get to the other side of the battery, powering the toy on its way. But when all the electrons are used up, the batteries are … Continue reading →

After a significant number of charge cycles, A lithium batteries maximum charge capacity will decrease. For these batteries, this degradation process typically begins at around 1500 – 2000 cycles. Most electric vehicle batteries have an estimated 1500 to 2000 charge … Continue reading →

ionic compound. An ionic compound is most likely a solid at room temperature and pressure, whereas a covalent compound may be a solid, a liquid, or a gas. B Among the covalent compounds, those that are relatively nonpolar and have … Continue reading →

Expect the charging time to be upwards of 5 hours, around 6 hours or so. Also if it a lead acid battery your are charging it a bit too fast. It should be charged over a period of 10 hours … Continue reading →

Adjusting the voltage lower or higher will change the brightness, but only because it also changes the current- higher voltage means the current will increase in an LED. Does LED brightness change with voltage or current? As the current through … Continue reading →
