I wasn't paying attention. Earth Day is today. If I would have thought of this before, I could have done something awesome. Instead, here are some reposts related to the Earth and energy. They have been sitting for a while in my post-compost, so they are nice and smelly.
Most of these deal with Earth-type stuff and energy.
Rotation of the Earth as an energy source. What if we could some how use the rotational energy of the Earth? How much would we have to slow it down to get something useful?
Solar Powered motorcycle - possible? There was this story about an electric motorcycle that is recharged by solar cells. How far could you go in a day with this? (spreadsheet calculations included).
Which saves more gas - turning off daytime running lights or slowing down? That pretty much sums up that post.
Chevyvoltology 101. So, the Chevy Volt is this plug in hybrid car. There were some questions that came up - how many equivalent miles per gallon would it get? See, the problem was that they were trying to calculate the miles per gallon for when it was in the city and not using gas. Well, what about miles per dollar? What about CO2 per mile?
How much gas could we save by removing drive throughs? Some estimations and calculations here.
How much would free energy cost? There was this news story a while back about this grocery store that installed these speed bumps that would transfer kinetic energy of cars into something to be used by the store. How would this work? Could you get this to power the whole store?
Charging an electric motorcycle with wind power. There was this electric bike called the Killacycle. They claimed it could be recharged in 4 minutes and it could be recharged by wind power. Could it do these at the same time? (recharge by wind in 4 minutes)
