AGNI focuses a beam of ions, which is half of the fuel, onto a solid target which is the other half of the fuel. As far as I can make out this is beam-target fusion, not beam driven inertial confinement. Everything I've seen about that approach is not favorable to net fusion gain. And the described...

Contrast with the SLS, "designed for manned flight", but unlikely to even have half that many launches, if it flies at all.
Can you unpack what you mean with "short term" beyond "5 seconds". Also, "high capacity storage"? I recall articles from the late 1970s, early 1980s, when it was hoped that advanced flywheels could match batteries for energy capacity, and hold it for hours or even days...
Flywheels have applications. They do great for surge delivery of mechanical energy. The high energy density flywheels intended to replace large batteries haven't delivered the combination of attributes to compete for that purpose. Battery tech having advanced at the same time the flywheels were rese...
The falcon 9 or heavy do not fulfill the mars/ moonraker 8) roll that NASA has envisioned. I will take the support of a government to have a new colony on mars and I feel the BFR is the only way NASA will get on board with the program. Once NASA figures out they can launch probes using the BFR they...
If a second stage is recoverable, return to launch site about a day after liftoff isn't difficult. Just wait in orbit until the launch site again approaches the orbital ground-path. Return to launch site after a single orbit is harder, especially from high inclination orbits. Recovering a second sta...

Why do you hate plants, and wish to starve them of the CO2 they need to grow?
