I'd love to see your interpretation of rails shooter like "The House of the Dead."
I'm imagining a branching "storyline"/exercise routine. One path might have many very weak enemies that take somewhat precise combos where another might have stronger minibosses where its a slugfest.
A long time ago I used an rtlsdr hooked up via usb-otg in order to track aircraft [1].
I'd be really interested in a minified version that didnt need the otg dongle. Or even a stand alone battery operated sdr that could be controlled with bluetooth? I dunno how big that market is, especially absent a network like you propose.
Certainly prevalent forms of argiculture are akin to surface mining. My property is surrounded on three sides by a rotated field (corn, wheat, soy etc) and there's a 12-18" drop along those edges of my property line, persumably as the soil was extracted in plant form.
However I believe there are forms of soil agriculture that aren't surface mining such as a short rotation coppice. The primary molecular structures being extracted are lignin and cellulose, which are comprised of carbon, hydrogen and oxygen (that is, water and air sources).
Thanks for throwing up the Ethics flag.
Discussing/brainstorming this in a public forum is volunteering your brainpower in support of murderers.
