[6]Where is mechanosynthesis? In progress but underfunded.
[7]IEEE Spectrum asks where is my mechanosynthesis?
[8]Richard Smalley proposed a carbon nanotube energy grid back in 1995
Where is this carbon nanotube energy grid ?
Where is there even one test of commercial carbon nanotube quantum
wiring ?
They received at least $11 million to work specifically on this
project. Billions have been spend working on carbon nanotube research
and development.
Billions of dollars and thousands of people have been spent decades
working on commercially viable nuclear fusion. Where is the first
commercially purchased watt of power from nuclear fusion ? Is this
science supposed to be believed ?
I know that there are difficult challenges that are worth doing, that
take a lot of time and money. The question is what is the best plan to
achieve goals. The questions that I posed against tokomak nuclear
fusion and a carbon nanotube energy grid are unfair, but they are less
unfair than the questions posed about mechanosythesis. Also, narrowing
the concept of molecular manufacturing to only mechanosynthesis is
also unfair.
The focus on mechanosynthesis is like someone predicting powered
flight with the eventual superiority of jet engines, but also
mentioning powered blimps and prop planes. When the other things are
developed and dominate for some decades, the question comes in 1920
where are the jet planes ?
1. It is still coming
2. Get a well funded project together and if that has cost overruns or
delays or has development issues then more informed questions can be
made about the end goal.
The IEEE Spectrum article discusses head scratching about the less
than expected progress towards molecular manufacturing. It is obvious
why it has not developed further. There has not been enough direct
funded effort made to try to develop it.
[9]The conference presentations and [10]liveblogging transcript show
very little discussion about the topic of the events of the last two
decades pace of progress.
The IEEE article asks has not James Von Ehr spent $100 million towards
developing mechanosynthesis ? No he has not. Von Ehr has a lot of
money but he did not use it all to fund a direct to MNT effort. He has
created Zyvex which provide tools, instrumentation, and applications
to serve the semiconductor and advanced research markets.
Zyvex has an atomically precise manufacturing effort, but it has been
a fraction of the overall funding and effort. Going forward it will be
focused on atomic layer deposition for the next few years.
Zyvex plan: start with hydrogen passivated silicon surface,
depassivation, self-limited deposition, despassivation, repeat. We
want to make this more engineering-oriented, repeatedly, with higher
yields. We have a few products in mind for single-probe operations. We
can make money even with this, with the right products. Next: MEMS
arrays.
Atomically precise manufacturing will lead to "digital matter" which
will deliver similar benefits as digitization of information.
It is a prudent plan given the resources available to Zyvex and Von
Ehr.
Also, molecular manufacturing can and should be achieved through means
other than mechanosynthesis (at least initially). Please look at the
conference paper from
[11]Toth Fejel on the various ways to reach the goal.
