This 'dual-use' electric tractor can sow fields and run guns

Breakthroughs, discoveries, and DIY tips sent every weekday. A Spanish startup called Voltrac says it is building a new breed of smart tractor--one that could sow fields by day and run weapons to soldiers by night. And while the Hot Wheels-looking, fully electric tractor is currently remote-controlled, Voltrac is working to make its next version fully autonomous. This "dual-use" tractor, first spotted by The Next Web, reportedly weighs 3.5 tons--roughly the size of a young African elephant--and has a carrying capacity of nearly 8,900 pounds. It can reach a top speed of around 24 miles per hour and operate for anywhere between 8 to 20 hours, thanks to two large 200kW batteries.
