| Solar-Powered Aircraft | ||
| A plane powered entirely by solar energy. |
I don't know who first thought of powering an aircraft with solar energy alone; as far as I know, working models didn't appear until the 1970's. So, this is a fairly early mention of the idea.
| "Dad, I believe that you have been trying to develop a successful solar engine. One that could be placed in the wings of a plane to generate power from the light falling on that surface..."
"...the one big trouble with all solar engines, eliminating the obvious restriction that they decidedly aren't dependable for night work, is the difficulty of getting an area to absorb the energy. |

'A metal... light as cork and stronger than steel...'
'Ken lay full-length in the padded body compartment, his feet resting on the controlling bars of the directional planes, hands on the torpoon's engine levers.'
'... little machines, that went from plant to plant... cutting off the ripe fruit.'
'Recharge the batteries... in almost every town and village...'
'...a tiny, rocket-powered projectile, drove towards the mysterious bulk. It hit, exploding into a cloud of incandescent vapour.'
'The flycycles were miracles of compact design.'
These drones can provide situational awareness beyond visual line-of-sight capability.
'It resembled conventional human-operated transportation vehicles, but with one exception -- there was no driver's cabin.'
'Each one consists of a hub with many tiny spokes... On the end is a squat foot, rubber tread on the bottom...'
'A paper thin polycarbon screen unfurled silently from the top of the unit and immediately grew rigid.'
