i know this; and a fusion reactor might be one

Nukes are not perpetual, they are just an exceptionally long lasting energy source

because no net output as of yet....

No energy source lasts forever

Perpetual motion machines are impossible cause friction on a planetary level, and there is also friction in space because Space isn't a vacuum devoid of gravity

no shit sherlock

Thermodynamics called, it said you need an award for being mr obvious

nuclear fusion might also be infeasible in terms of getting more out than you put in

@ManAnimal its not actaully

ITER split even on input-output in 2008

it's quite feasible within this century even

yes, quite actually; science is easy; engineering i hard

That's about the best the fusion got so far

@SideTracker it's definitely not doable

yes, so stil qualifies as 'perpetual motion'

Ein >= Eout

No

It won't last forever

doable actually given how we are getting increasingly advanced with robotics and you dont need a human to build a reactor

Ehhhh

Not really

you can have a human guide it

but you dont need him to build it

any device that claims to have a net output GREATER than the input is a perpetual motion machine

hell we have surgeons getting replaced with robots now

it isn' t about duration; it's about efficency

and so far, scientists have been promising way more than the material sciences and other practical requirements can deliver

the ITER assembly plan is... well, the space shuttle was easier to assemble

lets see how the Tesla GigaFactory turns out in China and if it works we will build like 4 or 5 in the US

Telsa isn't very good at technology demonstrations

Musk is good at technology integrations

can't integrate what doesn't exist

the idea has to be sound and efficient

that's why we wait and see

if it turns out to be both

great
