  1. Re:Is it effective? on Removing CO2 From the Air Efficiently · · Score: 1

    Yeah, but how much energy does generating one tonne of CO2 give? It still just capturing CO2, they need still more energy to eventually convert it to fuel

    Burning a ton of coal for energy generates ~2000kWh of energy, and 3.7 tons of CO2 (since coal is mostly carbon). Using this device to sequester said CO2 is going to use 370 of those kWhs. So assuming there aren't any ineffiencies in scaling up the operation, we've just made coal carbon-neutral at a cost of about 20% of it's usefulness.

    Do things that require face to face communication, and that people can't get some other place.

    Sorry, can't think of anything that fits that description.

    A key-signing party would require face to face communication. You could use your organization to teach students about computer security. This is something I would have appreciated learning more about on campus.
