A proponent of the wind turbine shown at left writes:
I commented this 6 year’s ago . It is so simple even if you put in small stream 1 000 000 small turbines like this one, you will have more power. It’s the same for the wind , we don’t need this big huge wind Parks we need small efficient and most important easy for fixing and easy for installation. Not forgetting we can make smaller things with eco friendly materials.
Me:
There are a few reasons that claims like this are bullshit. The main one is that the power extracted from the wind is proportional to the square of the radius of the blades. We recall from our childhoods the formula: Area (of a circle) = pi r-squared. This is why real (not fictional) wind turbines are so large (and getting larger all the time).
Also, as I mention frequently, today’s wind turbines capture about 90% of the theoretically available kinetic energy from moving wind; given the laws of physics, there is no room for any significant increase in efficiency/output.
Even if neither of these were true, which would you rather cover the cost of maintaining: one large turbine or a million little ones?
I wish I had $100 for every time I heard some uneducated Trump supporter tell me this.
A democracy is a system where governmental power is derived directly from the will of the majority. A constitutional republic is a specific type of representative democracy where the people elect officials to govern, but those officials are strictly limited by a supreme, written constitution designed to protect minority rights from majority rule.
I remember a conservative friend who lived in Hawaii who complained that the native people objected to a project directed from Washington to build something at the top of one of their volcanoes, on the basis that this was their holy land. My friend asked, “Doesn’t the majority rule?”
“Not necessarily.” Trying to make my point in the simplest way possible, I explained, “People have rights. My neighbors like me, but imagine that they didn’t, and 20 of them, a 20:1 majority, wanted to come in here and beat me to death. I have a right not to murdered. When you think about it, we’re lucky not to live in a country where ‘the majority rules.’”
“Oh. I guess you’re right,” my friend said.
My biggest beef with Trump isn’t the many individual points of failure, but the fact that they are all the product of the mind of a criminal sociopath whose only way of thinking is self-enrichment, normally at the expense of anyone who cannot serve to make him richer and more powerful.
Neil DeGrasse Tyson says that our problem isn’t that our children don’t understand science, but that our adults don’t.
Three comments:
1) Wind is not a finite resource as long as the sun comes up every morning and disproportionately heats the Earth’s surface. 8th grade Earth science.
2) Wind doesn’t cool anything except the skins of certain animals that perspire. 9th grade biology.
3) Putting one’s ignorance of public display is not a strong idea, even in rural Texas.
