John L sez,
I'm skeptical, but I'll play along for a minute.

Sorry John L.
Convincing skeptics is not part of any scientific method I know of as skeptics demonstrate little if no training or formal education and do no real work, relying on the other fellow to do all the proof work and leg work so I do not play that game and instead spend my energy really working.

How do you get a 1000 ton (2,000,000 pound) engine into orbit? Does that include the propellant, or would you need to lift 900 tons of propellant, too? What about payload size and the size of the rest of the space craft?

For the earth launched 1000 ton engine powering a 100,000 ton rocket to Mars at a constant 1 g
Mrocketr=100,000 tons of payload and ship skin
Mexhaust~=1000 tons of 100 tons engine and 900 tons of propellant
Thrust== -436 trillion horse power
Mass converted to energy ~= 1 ton over 1.73 days
Total Impulse Momentum(Itot) =2887799039640 tons- feet/minute (deep space)
Isp = 1,494,200 seconds = specific impulse in earth's gravity field
Vescape from Earth = 11.2 km/sec; acceleration time at 1.2 g = 97.2 minutes
Vescape or landing on/from Mars ~= 3.7 km/sec; acceleration time at .53 g = 32.4 minutes
Vrocket peak at mid point=687.960 km/sec
Tmin = minimum distance one way trip time= 1.73 days 129.6 minutes = 1.82 days
Tmax = maximum distance coasting at zero mid journey for 1.45 days Tmin = 2.64 days
Round trip = 5.3 days (plus 1 day minus 3 days) depending on where Mars is at launch time using line of sight navigation

How much propellant would you require to make one of your light speed trips to Wolf359 (constant 1g acceleration)? How big would the vehicle have to be to hold that volume?
|
let me see; since I can get 100,000 tons to 687.960 km/sec at 1 g what payload mass can I get to light speed at 299792.458 km/sec? Ans. 1/435 that or 229 tons but as that makes the ratio of rocket mass / (rocket mass + engine mass) much less than one a rough numerical integration sez 115 tons flying by Wolf 359 at near light speed in 8.5 years since it took 356 days at 1 g to reach light speed.
However; for the constant 1 g trip the distance
Trip length: 7.5 light years.
Acceleration: 1.0 g.
Time on earth: 9.239173075887965 years.
Time on ship: 4.391194445054074 years.
therefore distance traveled / ship time gives a average warp speed of 1.7 and v peak at warp 3.4 then the ball park figure of 115 tons / 3.4 or
33.8 tons payload size with the single 1000 ton Mars engine is more practical and fitting your specifications and converting 1 ton of propellant fuel to the required energy.

How would you protect your vehicle from impacts with dust, solar wind ions, and micro-meteorites at high velocities? At just Earth orbit speeds a speck of dust will shoot through like a bullet. A baseball size rock would destroy a space ship.

Interstellar space is mostly empty as particle mass collects in stars gravity wells and I am traveling at a very small fraction of light speed in those wells so steer away from the asteroids and ort cloud of comets. Well outside those wells I am traveling at light speed and beyond and the probability of collision decreases when velocity increases so the probability of me colliding with any mass at light speed and beyond is insignificant if not zero.

And, most importantly, with the fight against using RTG's, how are you going to convince the public to let you launch this thing loaded with 1000kg of radioactive material???
|
Shhh. I am going to launch without telling anybody and just let them catch me if they can which they cannot.
Seriously. My engine cannot explode like chemical rockets often do and on earth launch I emit only a few grams of radioactive metal out the exhaust port collected at the bottom of a 300 meter deep launch tube in 1000 tons of water to be recycled. Likewise on earth landing in the same launch tube I turn the engine off by flushing approximately 1000 kg of hot radioactive metal out the exhaust port to cool in the 1000 tons of water at the bottom of the tube for recycling.
In any case earthlings become much safer as I remove the radioactive metals from decommissioned nuclear reactors and atomic bomb from the surface of the earth and deliver them to deep space out of the hands of terrorists at the cost of 6.5 cents per pound.
