Electric Jet Engine Uses 3D Printed Compressor, Skips The Turbine Altogether

Posted by in categories: 3D printing, energy, engineering, transportation

Turbojet engines are an incredible piece of 20th century engineering that except for some edge cases, have mostly been replaced by Turbofans. Still, even the most basic early designs were groundbreaking in their time. Material science was applied to make them more reliable, more powerful, and lighter. But all of those incredible advances go completely out the window when you’re [Joel] of [Integza], and you prefer to build your internal combustion engines using repurposed butane canisters and 3D printed parts as you see in the video below the break.

To understand [Integza]’s engine, a quick explanation of Turbojet engines is helpful. Just like any other internal combustion engine, air is compressed, fuel is burned, and the reaction produces work. In a turbojet, a compressor compresses air. Fuel is added in a combustor and ignited, and the expanding exhaust drives a turbine that in turn drives the compressor since both are attached to the same shaft. Exhaust whose energy isn’t spent in turning the turbine is expelled and produces thrust, which propels the engine and the vehicle it’s attached to in the opposite direction. Simple, right? Right! Until the 3D printer comes in.

Berlin Affordable Housing Challenge

Posted by in categories: business, government, habitats

The Berlin Affordable Housing Challenge is part of Bee Breeders’ Affordable Housing competition series. Run in partnership with ARCHHIVE BOOKS, this competition tasked participants with submitting innovative design proposals for tackling Berlin’s housing crisis.

Germany’s new government, formed in 2021, has vowed to make affordable housing a centerpiece of its agenda. Berlin, the capital city and the country’s center of gravity for entrepreneurship and new business, is in particular feeling extreme housing market pressures. According to an article published by NPR during the period of this competition, eight out of 10 city residents are now renters, where rent has increased 42% since 2016, and where an average of 40,000 new residents arrive each year.

Comparative analysis of genome code complexity and manufacturability with engineering benchmarks

Posted by in categories: bioengineering, biotech/medical, encryption

When knowledge has advanced to a state that includes a predictive understanding of the relationship between genome sequence and organism phenotype it will be possible for future engineers to design and produce synthetic organisms. However, the possibility of synthetic biology does not necessarily guarantee its feasibility, in much the same way that the possibility of a brute force attack fails to ensure the timely breaking of robust encryption. The size and range of natural genomes, from a few million base pairs for bacteria to over 100 billion base pairs for some plants, suggests it is necessary to evaluate the practical limits of designing genomes of similar complexity.

Elon Musk Warns That Russia May Be Spying on Starlink Connections

Posted by in categories: Elon Musk, internet

SpaceX CEO Elon Musk is warning users in Ukraine who have received one of the company’s Starlink dishes that the connection could be targeted by Russian state actors.

“Important warning: Starlink is the only non-Russian communications system still working in some parts of Ukraine, so probability of being targeted is high,” Musk tweeted on Thursday.

“Please use with caution,” he added.

Scientists Reveal a Multidimensional Universe Inside the Human Brain

Posted by in categories: computing, neuroscience

A study published in Frontiers in Computational Neuroscience has revealed that the human brain’s structures operate in up to 11 dimensions.

The dimensions are not understood as the classic definition of a dimension, which most of us understand, the Blue Brain Project explains.

One piece of good news as energy prices explode in European markets

Posted by in categories: energy, food

With the war in Ukraine raging and gas and energy prices climbing across world markets, there is one piece of good news for European energy markets.

Economists from Poland’s state Pekao bank are reporting a large reduction on the price of CO2 emission certificates. The prices have fallen dramatically from €95 to €62 per ton. This is especially good for countries like Poland, which are forced to pay a premium for energy derived from “dirty” sources like coal. The fall in the price of this “tax” is expected to make the cost of energy especially more bearable for many of Europe’s poorer nations.

The CEO of Poland’s Development Fund, Paweł Borys, also commented on the issue on Twitter. “It is significant how CO2 prices have collapsed, falling by 30 percent since they peaked in February. This is good news, as it means that electricity prices may fall, thereby reducing inflationary pressure that have been exacerbated by hikes in oil and food prices.”
