DailyDirt: Plenty Of Spaceships… Sorta

from the urls-we-dig-up dept

The number of ways to get a person into space is pretty limited at the moment. Only Russia and China have operational launch systems that can escape the Earth’s gravity (with people as passengers). There are a bunch more spaceships in development, though, so if you really want to get into space without a Soyuz or Shenzhou, you’ll have to be patient. There have been a few recent accidents, but it looks like engineers have figured out some of the problems.

After you’ve finished checking out those links, take a look at our Daily Deals for cool gadgets and other awesome stuff.

EM drive has been “validated” by 4 labs. One in the UK where the idea originated, one in China, one at NASA and now one in Germany. All of the labs, except possibly the Chinese one, have questionable pasts.

However, that doesn’t mean it doesn’t work. Contrary to what a lot of people say, the EM drive doesn’t have to violate any laws of physics. It just means that if it works, no one has figured out what it is pushing against yet.

Re: Re: Re:

That is NOT how the EM Drive supposedly works. It’s a closed system. The microwaves are not ejected out of the back, they remain in the chamber. If it works, it appears to somehow violates the conservation of momentum.

But unfortunately it seems that the data and methods from the German lab are shaky.

EM Drive

I plan on powering mine with a Molten Salt Liquid Thorium Fluoride Reactor with Magneto Hydrodynamic plasma extraction. It is the most energy dense solution I can come up with given current tech.
Current reports are giving the output around .2 newtons of force per watt of power, but theoretically 2 newtons per watt can be achieved. I would be very happy with the latter, but can work with even the former as long as I am out of the earths gravity well to begin with.
