RE. Re. I miss the days
Not all of us. Lat I heard there are some folks who are working on staged model rockets capable of launching micro Cubesats and suchlike.
Incidentally I did look into launching a hybrid Lifter/balloon aka Ionocraft but the problem is diminishing returns.
There is a workaround but not going to do anything as have enough issues with the authorities as it is but they know who I am :-)
Hint: It uses elements found in nature, in quantity and can be made using off the shelf equipment if you have very basic
skills in the art of Google-fu. To be honest the sort of power density is lower than chemical rockets but this isn't a problem for
very small payloads. (ie 5cm3 max weight of maybe 400g)
