Can a Vertical Lift Engine Hover With 30 Pounds?

AI Thread Summary
Designing a vertical lift engine to hover 30 pounds at a height of one foot poses significant challenges, particularly regarding power efficiency and stability. The discussion highlights that a skirted design could reduce power requirements by utilizing pressure differences rather than relying solely on thrust, while a skirtless design may lead to inefficiencies similar to traditional drones. Various aerodynamic effects, such as blown wings and momentum curtains, are being explored as alternatives to conventional propeller-driven methods. However, achieving the desired lift within the specified constraints of weight and power remains a complex engineering task. Overall, the feasibility of the project is questioned, with suggestions leaning towards hybrid designs or hovercraft principles for better efficiency.

The Hendo 2.0 looks closer to the concept I'm discussion with lift engines except I'm not considering magnetic fields at this point. I wonder why, since they have to ride over a conductive surface anyway, they don't engineer the power in through the copper surface instead of using battery power? Then they could go more than 10 minutes at a time. In the second video, the CEO says the Hendo 2.0 uses only 40W/KG so assuming about 150 kg for rider plus board, that's 8KW.

The OP in this thread is too defocused to be able to answer his questions.

@bob012345, If you have a more specific question, you are free to create a new thread.
