  1. Meh, it has good specific impulse, phase temperature overlap with liquid oxygen, and it can be synthesized through Mars ISRU

  2. @Richard Vaughn you are looking at current battery technology as it stands today. Theoretically, batteries can hold more energy density than they currently do, and it may be possible to further increase their energy density in the future. Only time will tell.

  3. The comment @0:50 is ignorant - India didn't carry out the test as an act of political posturing. India has a relatively large satellite infrastructure in space, but no way to deter any hostile power from destroying all that infrastructure. Meanwhile, the US is in the process of trying to set up a possible global treaty on Anti-Satellite (ASAT) weapons. In order for India to develop a credible deterrent, it would have to do an actual test before any such global moratorium came into place. Nextly, another major event had happened: There was a severe high-deathtoll terrorist attack on an Indian military base, in which not only soldiers but even their family members were targeted and killed. The jihadist attack was believed to have come from across the border, from the soil of a neighboring country. In response, India soon carried out a retaliatory cross-border ground strike to destroy the terrorist training camp across the border. That commando raid was aided by Indian ground-imaging satellites overhead. About 24 hours after this military operation occurred, US Space Command detected a "fragmentation event" in orbit at one of the Indian imaging satellites (RISAT-1), which simultaneously went dead. It is not known what caused this "fragmentation event", but the timing of this event invites natural suspicion. It was 2½ years after this particular event that India's recent ASAT test has occurred, which is about the amount of time it would take for India to set up such a test from scratch, once a go ahead was given.

  4.  @enderyu  why not a Tesla car - better than sending up a concrete bloc as a counterweight

  5. So quiet with no moving parts means good for surveillance drones? What about for commercial ones and not just military? But wouldn't the electrical voltage potentially attract lightning strikes?

  6. What about a rotary version? Is there any way to adapt this technology for some kind of rotary wing configuration? Just wondering.

  7. @Richard Vaughn as automobile batteries continue to advance, perhaps they'll eventually make aviation batteries more feasible.

  8. @Richard Vaughn aircraft can only use chemical energy, since nuclear is too dangerous. They already use chemical fuel, and there may be a way to get them to use electrochemical energy instead. But nuclear fission is far too dangerous. If even a small amount of nuclear fuel were released, it could have deadly effects and poison an area for thousands of years.
