Circa 2021


Mycelium is very light in weight, it naturally floats on water, it can withstand the cold of space where we don’t have to worry about cold welding, and we can add in fine strains of metal material which is used to transmit almost any type of signal. As you can see, there are numerous reasons why mycelium is quite suitable for our satellites in space, on land, and in the air on its way to space.

Of course, there’s also the all-important issue of space debris, which is projected to become a severe hazard to satellites and spacecraft in Low Earth Orbit (LEO) in the coming years.

According to the SDO, more than 560 break-ups, explosions, collisions, or anomalous events that resulted in fragmentation have taken place since the launch of the first artificial satellite in 1957 (Sputnik 1). With the proliferation of small satellites and the mega-constellations that are (or soon will be) deployed, the risk of collision rises considerably.

Simpler, faster, smaller, and cheaper chips are a key to low-power computing — even in AI.


RISC-V is taking off like a rocket.
In this video I discuss how RISC-V will reshape chip design industry.

On Monday, SpaceX was spotted loading some of the first Starlink V2 satellite prototypes into a custom mechanism designed to refill Starship’s magazine-like payload bay.

While it’s not the first time SpaceX has used the dispenser, the photos captured by photographer Kevin Randolph are the first to clearly show real prototypes of the next generation of Starlink satellites. According to CEO Elon Musk, those Starlink Gen2 or V2 satellites will be “at least 5 times better”, “an order of magnitude more capable,” and about four times heavier than current (V1.5) Starlink satellites.

The potential of the new satellite bus design paired with Starship’s massive fairing and lift capacity could dramatically improve the viability and cost-effectiveness of SpaceX’s Starlink constellation. First, though, the company needs to launch and qualify prototypes of the new satellite design and verify that all associated ground support equipment works as expected.

The transport sector is transforming towards climate-friendly powertrains with significantly reduced CO 2 emissions. The electrification of powertrains remains a major challenge not only for trucks, buses, trains, and ships but also for aircraft. These applications cannot be realized in the future with batteries because of the energy requirements. The fuel cell is an extremely promising energy supplier for these applications, which supplies electrical energy from stored hydrogen and ambient air.

Fraunhofer Institutes LBF, IFAM, IISB, and SCAI joined their forces to develop advanced and highly efficient components for fuel cells. The project HABICHT aims to design and develop a high-speed motor for a fuel cell compressor to enable innovation in the utility vehicle and aviation domain. The electric machine should at least achieve apower density of 30 kW/kgby using innovative materials for direct cooling of the stator and maximizing the rotor’shigh-speed capability (150.000 rpm). The rotor design will use a new manufacturing process to glue and pot the magnets to be suitable for high circumferential speeds.
