The Download: Questions over a clean fuel startup, and Chinese lockdown censorship

This is today's edition of The Download, our weekday newsletter that provides a daily dose of what's going on in the world of technology.

This $1.5 billion startup promised to deliver clean fuels as cheap as gas. Experts are deeply skeptical

Last summer, Rob McGinnis, the founder and chief executive of startup Prometheus Fuels, gathered investors in a parking lot in Santa Cruz, California, to show off his Maxwell Core." The pipe-shaped device is packed with a membrane riddled with carbon nanotubes, forming pores that separate alcohols from water.

That day, it was connected to a tank filled with both. As McGinnis explained how the technology worked, his staff used it to fill the tank of a Harley-Davidson motorcycle. The alcohol seeped through the membrane, concentrating it enough to power the vehicle, which had been converted to run on the fuel, he said.

It was a theatrical demonstration of the technology key to McGinnis's beguiling pitch: Prometheus will transform the global fuel sector by drawing greenhouse gas out of the air and converting it into carbon-neutral fuels that are as cheap as dirty, conventional ones.

But while investors have thrown money at the company, pushing it up to a valuation of more than $1.5 billion, there is little evidence it can actually live up to its lofty claims. Read the full story.

WeChat wants people to use its video platform. So they did, for digital protests.

Inside Shanghai: On Friday night, millions of people in China watched the same video on their phones: a six-minute montage of audio clips from the covid-19 lockdown in Shanghai, titled The Voice of April. Its emphasis on the lockdown's human toll struck a chord, and people shared it widely on WeChat and other messaging sites.

Inevitable censorship: Despite its reserved tone and lack of personal comment, even a safe" video can be seen as disruptive if it reaches too large an audience in China's political reality. State censors began quickly scrubbing the clip from messaging sites, prompting people to find clever ways to dodge censorship and help it reach the next viewer.

Resisting erasure: Chinese people have used every technological tool at their disposal to circumvent or deceive the pandemic censorship machine, including disguising the video by embedding it in other clips, overlaying its audio onto other videos, and using QR codes to share the video's link. But while the censors succeeded in getting the clip taken down, the dead links to the original remain on people's timelines, reminding everyone of what happened. Read the full story.
