I have more than 250Q/s energy generation, and plenty of science, but the project won't work =( I assume that you don't have to use space energy gen for it, because I've had my dyson collectors on auto build since I unlocked them and I'm only at 16Q/s so I doubt I have to just wait for my dyson swarm to get strong enough. I also double checked that my mega project tab was using colony resources. 
I love the game, hope that I can get past this

You need enough energy storage to run it for one second, so 250Q in this case. Sidestep consumes energy from actual stored energy, not production.

oh my gosh of course!!!! I can't believe I didn't think about that! I could have progressed HOURS ago lol. Thank you so much
