i've looked around everywhere but i cant find out how to research graviton it says i need 300 energy and i have more then that but i cant research it because my energy will go into minus can anyone tell whats wrong with this....i have everything needed i just dont have the option to research......also i dont have the hyper space engine level required for the death star could that be the reason?

You need three hundred THOUSAND.

Get a good nanite factory on a hot planet and build a bunch of solar satellites.

Is that 300K total energy, or 300K free energy? TIA

Total energy

1. Get a planet in slot 1
2. build up robot factory to 12
3. build nanite Factory to 3
4. build Shipyard to 12 or 13
5. use this formula to calculate the # of sats you need: (300,000-Solar Plant and Fusion Reactor output)/((minimum planet temp*.166)+20)
(thanks Witchy spanky and gale)
6. calculate how much rez you will need
7. get it all in place
8 build em all as fast as you can
9. pray

after getting the research (wich is instant) call a friend (or enemy) to do a moonshot with all those sats
then take the res and use it for your first rip

Corbeil made a sat calculator. It's in the Programs thread at the top of the Help section.

so i need 300k total energy how many satelites will i need for that? i have sumthing like 9,981 energy is that not anuff?

Depend on the planet temp, but that sounds enough for a planet that has double plus temp, like 40-80 or something...

also be patient and wait till you can instant build sats before you go for graviton

you only need graviton to get deathstar and in early game you only need deathstar for fleetsaving
