Re: Back of a fag packet
The problem with the He balloon proposal is that all He on Earth is a byproduct of radioactive decay (Alpha particles). This would mean that your balloon system would be nuclear powered and there would be more untutored, tofu-eating, sandal-wearing, wet liberal protesters painting their faces and laying down on railroad tracks than could be secretly sponsored by the minority political party.
There is also a big problem with He availability for any vigorous launch campaign.
