Re: Moon or Mars?

Quite true. I think we could use the moon as a base for a large asteroid mining project. The lower gravity well would be the most prominent advantage over earth. Also, we could take asteroids to the surface of the moon and mine them there, reducing the kit needed on ships because they just push aste...

Re: Time Without Change

I have, in the past, wondered something similar. If time were to travel backwards a short distance, then forwards again, and all particles were subject to this,we would have no idea or memory of such a phenomenon. Kind of like; time travels in both directions at all possible speeds, but we only reme...

Re: Favorite home experiments

Quite an entertaining one I've done in the lab was to bubble the gas from the taps into a washing up liquid/water mix. Loads of natural gas bubbles, add one lit splint - whoosh. Lots of fire :) Not much of an "experiment" really, but certainly fun. You can do a similar thing by electrolys...

Re: Using solar heated water to generate electricity

You could try running the water over a painted black surface under glass to heat it. Using multiple glass sheets to insulate the water, you could achieve a higher temperature, but at the cost of reflecting more solar energy, thereby making it less efficient overall. Building a demonstrator would be ...
