Three Interesting (And Incorrect) Theories about the Great Pyramids

Science has done a lot of speculation on the building of the Great Pyramids. As a result, some intriguing theories have gained traction over the years.

Not a Single Block Moved

The logistics of moving such massive blocks of limestone is too cumbersome to be done by men. It would take 8 men, each lifting roughly 900 pounds, to carry the block any distance at all. Instead, Dr. Joseph Davidots proposed that the Egyptians used an alchemical process to simply cast the pyramid the way we build a sidewalk. They used wooden frames and built the pyramids up block by block. While an amazing story, the theory was based on poor evidence and a small sample size of limestone. It also doesn’t explain the plethora of tools uncovered at the pyramid sites.

 Solitron Energy Levitation

If it sounds like something out of Scientology, it might as well be. This theory was advanced by a few thinkers in the 1980s. Essentially priests erected and tuned large coils which led up the pyramids. Blocks would get caught in the field of energy, which would levitate and transport them to their destination. Unfortunately, as cool as this theory sounds, there is not a shred of evidence to support it.

 Magical Beings

In what is perhaps the biggest insult to Egyptian ingenuity (which was fairly amazing, by the way) the people of the lost city of Atlantis were apparently responsible. There is no specific group claiming dominion over this idea, but aliens and mysterious beings continue to be viewed as explanations for amazing feats like the Pyramids of Giza, the Easter Island heads, and Stonehenge.

The Importance of Keeping Spare Energy on Hand

January 24, 2014 by · Leave a Comment 

There’s almost no part of our daily lives that isn’t somehow connected to energy. Whether it’s the cars we take to work or the grocery store, the phones we can’t stop using or the homes we spend most of our time in, energy is all around us and we wouldn’t know what to do without it. Unfortunately, many people have to find out the hard way. Just about every year in recent memory has involved some kind of natural disaster that left people without the many modern amenities we all take for granted.

This is why it’s so important to have other options when it comes to energy. Whether it’s storing extra lithium batteries or generators for things like 28 volt power supplies, the recent past should teach us that we don’t want to risk being left in the dark.

Fortunately, this is easier to do than ever before. The modern world is full of options for keeping spare energy around for when times get really tough. Generators, for example, are more affordable and convenient than most of us understand. If a natural disaster takes electricity from our home, a diesel generator can get it back up and running for the foreseeable future. Even those batteries can power a number of tools that can make all the difference.

It’s always a good idea to be optimistic, but don’t fool yourself into thinking a disaster couldn’t change your world immediately. Keep spare power so when the worst happens, you’ll be ready.

What if you need a custom-built unit? The key is to find a lightweight, reliable system that can be easily carried on board the aircraft. Here’s a look at the top portable power starting units for the aviation industry.

Lithium Portable Starting Units

Lithium is a popular choice for battery packs. Lithium portable starting units for the aviation industry come in a variety of sizes, from packs designed for small to medium size turbine engines to units that offer power to all electrically-started turbine engines. It’s important to find the right size battery pack that offers the features you need. Start Pac offers a lithium ion starting unit that is a full 26VDC battery pack, featuring a built-in charger. The charger offers 4.0 amps output and can be recharged for nearly six hours. This unit can be used for aircraft such as the Phenom 100 and Eclipse 500.

Why Lithium?

There are many benefits to owning lithium portable starting units. Lithium batteries are 42 percent lighter and 32 percent smaller than lead-acid batteries. Lithium battery packs also last longer; they offer twice the battery life of lead-acid batteries. What’s more, lithium battery packs don’t have sulfaction issues, which means they can be discarded without damaging the battery plates.

Lead Acid Portable Starting Units

The aviation industry uses a wide variety of lead acid battery packs for repeated starts and maintenance functions. This type of battery packs are available in 24-volt or 28 volt battery pack devices and offer large battery capacities. Start Pac, for example, offers a model that features separate removable batteries that can be changed in seconds. The 1324-1QC can be used to start turbine or piston engines with up to 500 horsepower. This specific model offers a charge time of nearly four hours and gives two to three starts between charges.
