Solar sailing

Nobody knows which types of propulsion will prevail in future space travel. Perhaps one key technology will be solar sails:
A team of scientists in Finland has woven a new type of spider web-like solar sail, with positively charged wires, that might be able to repel positive ions in the solar wind and thus propel itself through space.
I look forward to a time when solar-sail snobs look down upon nuclear-rocket people as uncouth.
