i just thought it would be interesting to know that's all. thanks for the post

After seeing some people with these motorized skateboards i kind of wanted to try and make one. Does anyone know the best types of motors electric/gas? I would prefer an electric one but I am not sure if i could get it too fast with an electric. Well first off what are the advantages of electric...

just out of curiosity if i wanted to lift something about 150lbs out of the air with a jet engine or rocket, to hold it against the Earth's gravitational pull 9.8m/s how much energy/power would i need? would it also depend on how heavy the engine is? and what other factors are there in this problem?

I don't know a lot about jet engines and how they exactly work but is it possible to run a jet engine without gasoline? Are there any different fuels that can be used for the engine to give more propulsion or give it more time in the air?

hmm that's interesting what the specific impulse for that mixture just wondering? also I am not sure if there is or not but are there any ways to make electric propulsion that you know of? or anyone else if they read this?

well is there a way to create a lot of electricity from a small source? Like a really powerful fuel cell? or a super battery lol? as an example, would it be possible to power an entire house with something as small as a shoebox?

I want to get a little into rocketry and i want to know what are the best chemical mixes for solid and liquid state rockets? also i wanted to know if there are such things as super chemicals. I am not sure if i made that up or not or it just a different word but, what i mean are chemicals that...

well I am not sure if this is the right thread because I am new, but i wanted to know. what are the most efficient ways of making electricity besides nuclear? Is there a way to create a lot of electricity from a relatively small source? Is there any new research or development of this topic?
