I saw two extreme posts / articles on Facebook this morning. The contrast was so dramatic that I have to write something on this observation.
The Warp Drive (EM Drive) is currently being developed by the NASA and the Chinese who is rumored to have successfully tested the device. It is a propullentless propulsion system (against the physical law as is generally known) that can send man to Mars in weeks.... a kind of must-have for man's exploration / conquest of outer space.
The other device is extremely down-to-earth and low-tech. It is called TLUD (Top-Lit Updraft) Kiln or burner that uses organic wastes to generate heat AND produces bio-char (biological charcoal) that has been proven to be an excellent additive for soil enrichment. It is also possibly the only carbon-negative way of heating, through partial combustion (pyrolysis). The whole process therefore locks-in carbon-dioxide from the air (through photosynthesis by plants as organic wastes) in the form of bio-char.... an excellent way to control global warming.
Will humanity's future depends on our ability to "migrate" to Mars (possibly via Warp Drive) or other planets? OR alternatively embrace Mother Earth with a new version of Ecological Civilization..... Why not BOTH, indeed?!
