A researcher in New York is building fish robots that infiltrate schools of fish and take them over. The cyberfish could be used to lead fish away from unsafe underwater turbines or other hazards. The same mathematical models that drive them could conceivably be used to lure birds to new wintering grounds or even to herd mammals, the researchers say.
A small kibbutz in Israel has installed the world’s first solar-hybrid power plant to fulfill all their energy needs. Composed of 30 solar reflectors and one kooky-looking “flower” tower, the plant can switch to gas-powered turbines after dark to keep the system producing power 24-hours a day. The best part is that the plant takes up a relatively small amount of space for its output and can power remote areas that are not connected to larger grids.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
