Solar-powered aircraft flown for nearly three weeks without landing
This is great and points to how solar in some cases already can facilitate continuous operation without the need for refueling of planes, boats, cars, you name it. Expect this to grow as battery and solar cell tech develops further.My favorites atm are the yachts that are capable of sailing just about anywhere in the world without a drop of fuel. The price is prohibitive, but considering that you might not need a house anymore it is actually getting close to possible for a reasonably senior tech employee.[full disclosure: no affiliation]https://www.azura-marine.com/aquanima-45/https://www.silent-yachts.com/silent60/
