Yes,yes,yes but what is it and does it actually fly?? Cockpit visibility doesn't seem all that great.

Yes it does fly, that black thing under the wing is an electric motor plus one on the other side and one at the tail.

It is an autonomous crop sprayer and would have a spray bar under each wing but not on at the moment.

Fully electric.

When you see a retired commercial autonomous electric aeroplane in a museum, you know that the future is now! :YMAPPLAUSE:

It feels like it was only a decade ago that people were deriding the idea of an electric car. Now look at 'em!

Nothing new under the sun. Raytheon touted the use of electtric beamed powered UAV's back in the 1950's.
Beamed Power UAV Experiments

The idea of using UAVs as a cheaper alternative to satellites for atmospheric research, earth and weather observation, and particularly communications goes back at least to the late 1950s, with conceptual studies focused on UAVs with conventional propulsion, or new forms of propulsion using microwave beamed power or photovoltaic solar cells.

Raytheon suggested what would now be described as a UAV using beamed power, flying at an altitude of 15 kilometers (9.3 mi), as far back as 1959, and actually performed a proof-of-concept demonstration in 1964, with a transmitting antenna powering a helicopter on a 20 meter (65 foot) tether. The helicopter carried a rectifying antenna or "rectenna" array incorporating thousands of diodes to convert the microwave beam into useful electrical power.

The 1964 demonstration received a good deal of publicity, but nothing came of it, since enthusiasm for Earth satellites was very high and the rectenna system was heavy and inefficient. However, in the 1970s, NASA became interested in beamed power for space applications, and, in 1982, published a design for a much lighter and cheaper rectenna system.

The NASA rectenna was made of a thin plastic film, with dipole antennas and receiving circuits embedded in its surface. In 1987, the Canadian Communications Research Center used such an improved rectenna to power a UAV with a wingspan of 5 meters (16 feet 5 inches) and a weight of 4.5 kilograms (9.9 pounds), as part of the "Stationary High Altitude Relay Platform (SHARP)" project. The SHARP UAV flew in a circle at 150 meters (490 feet) above a transmitting antenna. The UAV required 150 watts, and was able to obtain this level of power from the 6 to 12 kilowatt microwave beam.

Pffftttt! I made a beam powered radio receiver in between going to school each day.

Tesla had a few ideas about that.

Oops!! Did I say Tesla? :ymblushing:

Your name is RIck, really, isn't it, even if my name isn't Morty?




I raise you one positronic oberizer and put another 500 hundred Kilgorian sheckles on the magnetically levitating table. =))

You mention Tesla? Do bears ***** in the woods? Does TGG post music videos? =))

One would almost think you were a chauvinistic Tesla car owner... :p
