Well, the acceleration due to gravity, g = 9.8 m/s2

The radius of the earth, R = 6.4 × 106 m

The escape velocity of the earth, ve = √2 × 9.8 × 6.4 × 106

Therefore, ve = 11.2 × 103 m/s = 11.2 km/s

So escape velocity is around 11,200 m/s. or 36,745 fps

So this is similar to the solar panel scams for investors?

Take their money and run?

36,745 fps = 25,053.409 mph

They are not even close.

You don’t need escape velocity to go into orbit. You only need orbital velocity, around 18000 mph. But if you tried to accelerate something to that velocity on Earth’s surface, (a) it would burn up; (b) whatever didn’t burn up would not be moving at orbital velocity once it got to space.

Thanks for the math. I have done poorly at it, but have enough furiosity to be dangerous. Would not the acceleration due to gravity decrease with height?

From online converter 36745Feet/second = 25053 Miles/hour!

Yeah, but can you thread a needle?
