ZAP has updated their website:
https://www.zapenergyinc.com/
Plans to achieve Q~1 by 2022! That is aggressive though not surprising for me, given their track record to date and quite frankly, I would not be surprised if they got there sooner. In any case, the race is getting hot and ZAP is among the hottest contenders.

Oil major Chevron Corp (CVX.N) said on Wednesday it is investing in Zap Energy Inc, joining Italy’s ENI (ENI.MI) and Norwegian state oil company Equinor (EQNR.OL) who have also backed nuclear fusion startups to reduce their carbon footprint.

Zap Energy raised $6.5 million from its Series A financing on July 12, according to data from Crunchbase.

Yes, I just saw that as well! Very exciting news for Uri and the fellows at ZAP! I am very happy for them.

Some more interesting tidbits about ZAP:
https://arpa-e.energy.gov/?q=slick-shee ... mprovement
There are also new sections on their website for the board of directors and careers:
https://www.zapenergyinc.com/board
https://www.zapenergyinc.com/careers

Also, from the recent IAEA conference presentation by Uri, it looks like neutron yield is increasing with pinch current at somewhere between the 8th and the 10th power.

Edit: Updated website now available. That one is a lot more readable:

ZAP BETHE Kickoff- presentation:
https://arpa-e.energy.gov/sites/default ... Nelson.pdf

New prototype in the works: FuZE-Q
I presume that the Q is a reference to Q=1, but I might be wrong.
BETHE tasks:

▸Build and commission new, more capable, SFS Z-pinch FuZE-Q

▸Improved diagnostics to resolve higher current, higher temperature, higher density, and smaller diameter pinches
– Higher-resolution spatial- and time-resolved diagnostics for temperature, density, and PMI measurements
– X-ray & Thomson scattering Temeasurements and imaging (with ARPA-E Diagnostic and Capability Teams)

▸High-fidelity computational studies
– Electrode PMI studies, separate formation/acceleration concepts, validation, etc.

▸Evaluate SFS Z-pinch concept at higher performance

▸Verify scaling to higher currents
– Improved 𝑛𝑛𝑘𝑘𝑘𝑘𝜏𝜏
– Higher-resolution diagnostics

▸Computationally evaluate effects of PMI, as well as independent control of acceleration and compression processes
– Improved electrode designs– Improved operational domains

▸Evaluate scaling* for SFS Z-pinch reactor and economics
– Compact, no coils, TBR > 1.1 with liquid PbLiwalls, Pth~ 200 MW**
