Is everybody dead of the chinese virus?

This isn't a very high volume site to start with, but some of the foremost posters seemed to have left last year, and then the downtime from January to May put a further damper on participation (i.e. some people stopped checking in).

the rotating detonation engine is tantalizingly simple in a mechanical sense, but this self-propagating detonation wave has proven torturously difficult to achieve and sustain. Until now, it seems. A team at the University of Central Florida, working alongside the Rotating Detonation Rocket Engine ...

Here's a three-minute video presentation by their CEO, Jonathan Carling:

He says they've completed another round of funding and are very well funded going into the "end of 2019", so it's a little dated.

The thing that started Roger Shawyer off was his observations of certain perturbations in satellite orbits. I wonder whether anyone ever came up with a plausible explanation for them.

There's an interesting note that the battery doesn't need pure aluminum to operate. So maybe the plan is to buy inexpensive scrap aluminum and include that in the recycling? A quickie Google search suggests an aluminum can is worth 1.7 cents at a recycling center. About 70 cans to the kilogram. That...

Hopefully true? The Daily Mail isn't the greatest source. Take it with an enormous grain of salt, who knows what problems aren't mentioned. https://www.dailymail.co.uk/news/article-7592485/Father-eight-invents-electric-car-battery-drivers-1-500-miles-without-charging-it.html electrolyte is neither p...

Wasn't there another ST startup in the UK?

I haven't heard of another one. There's FIrst Light Fusion but they're trying inertial confinement.

UK hatches plan to build world's first fusion power plan t Nuclear scientists are designing an ambitious prototype facility that could demonstrate commercial energy production by 2040. The British government announced a £200-million (US$248-million) investment on 3 October. So more funding than the...

SNC's upper-stage Vortex engine will be used on board the Dream Chaser spacecraft, which is expected to launch from a ULA Atlas V rocket and run cargo missions to the International Space Station as early as 2021.

They claim: 1400 Wh/l and 405 Wh/kg using etched silicon wafers: each 12-inch silicon wafer consists of some 36 million of these vertical “micro-batteries” machined into the wafer’s surface. Which, as the explainer video argues, decreases the charge time of the macro-battery (made up of many micro-b...

In November 2017, Terrestrial Energy completed the first engineering program for the IMSR® design and the first step of the Canadian regulatory phase — Phase I of CNSC’s Vendor Design Review. This is a first for an advanced reactor. In addition, IMSR® power plant site selection work is underway in ...

I hope it works out that way (StarLink giving Musk oodles of cash to play with). I'll be looking very closely at signing up once StarLink goes into service.

They've set up a company to develop this:
