Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load. With the power setting fixed, the wheel would spin increasingly fast and the amperage drawn from the battery would steadily increase.

China leads the pack with a 40-70% cost reduction in utility-scale solar, onshore wind, and offshore wind compared to other Asia Pacific markets. Wind power isn’t far behind While solar is surging ahead in terms of cost-effectiveness, onshore wind isn’t far behind despite costs being 38% more than solar in 2023.

These high-flying, low-tech aircraft are already in use for surveillance, hovering at 18,000 to 27,000 meters to track drug runners. As a bonus, the tech onboard the balloons runs on solar power. It’s about one-twentieth the size of the minibus-scale geostationary satellites already in orbit, allowing for cheap and quick deployment.

The biggest leap forward happened in 2012 when it was discovered that USB stick TV tuners using the RTL2832U demodulator chip could be tapped to make very cheap but effective SDR receivers. Building off the demand stimulated by this activity, a number of manufacturers have started making premium, but still relatively cheap, SDRs.

Imagine using cheap wind- and solar-generated electricity to pull carbon out of the atmosphere and turn it into feedstock for large-scale 3D printing of building components. And as 3D printing progresses to larger and stronger components, even the structural elements will be freed from the tyranny of perpendicularity.

Needless to say, the combination of rare earth magnets and a carbon fiber composite frame to hold them does not make for a cheap rotor assembly. This article appeared in Charged Issue 54 – March/April 2021 – Subscribe now.
