Laser satellite weaponry is already here. It wouldn't matter if DARPA undertakes this project or someone else. I think it's still a good idea, if it can deliver energy cheaper than building, maintaining, and running a ground infrastructure. It could potentially lead to greater energy security. I just imagine satellites powering individual city blocks or segments, right along with remote villages. I wonder what the radiation effect is from energy delivered by laser...
How will we know the effects and timing (permanence) of injecting the stratosphere with aerosols that block out solar radiation? Is it localized (how will such gases stay over particular areas such as the poles), because gases expand indefinitely...right? How would we control these aerosols so the earth doesn't get too cold?
I think it seems like a good idea, and I'm sure there are experts that could answer these questions.
I give the Whitehouse kudos for proposing such an initiative, at least through research we will know more about what is possible and the effects of such actions.
The paper provides a great overview of how to achieve a more sustainable earth. Hopefully these actions could be consistent over the long term.
Why don't the stock market traders just use satellite? Shouldn't those transmissions be faster than cable transmission? They are only gaining milliseconds right? I wonder who will be affected. It seems like a lot of wattage, but the stock traders antennas are located in the upper US.
Yea, I feel like Aliens is not so far out of a possibility, and the theories are fun to play with... yet something grounds me and says there just are (and have been) some really smart people out there.
I've got a RTL SDR on order, and I plan on using it with SDR#. Mainly I will be exploring the radio airwaves, seeing what's out there. I just wish there was an inexpensive SDR that would also transmit, especially for amateur radio frequencies.
