PV Gap

Joseph Said:

do you use any more power solar or electric by having your radio/TV turned up to a higher volume?

We Answered:

Yes. The higher the volume, the more power the TV has to draw to amplify the sound. The same with a radio. Your tv or radio will only draw up to its maxium wattage. So if you have something with low wattage, it means its using less power, even with the volume up, than something with a high wattage.

What technologies could we use to replace oil?

We Answered:

Ethanol is promising, also various hybrid engines are helpful. If governments weren't so reliant on the taxes on gasoline (that's right, I said it) and the sellers of it weren't so greedy, I suspect we already could have converted much of our technology to electric or solar. Also, hydrogen could be used if a better way to utilize it was found.
The only way we could have a balanced ecosystem in space would be to find places where the raw materials we need (minerals, metals, etc) were readily available, or else all the materials we need will be coming off of Earth, and supplies are limited here.

I think on of the main problems standing in the way of us as a planet converting to better energy sources then this are red tape, and overall, greed. If people weren't so set on squeezing money out of the industry (it was only a few years ago oil was $30 a barrel) engines with a higher efficiency could have been in cars and equipment for decades probably. Car engines currently only use about %10 of the gasoline, the rest is wasted. But how would companies make the money if you only needed a 3 gallon tank?

sorry to get a bit ranty.
