Comment Re:How efficient is hydrogen really? (Score 1) 199

Another thing, H2O is a lousy combustion product if you are building an ICE. The problem is that H2O has a very high heat of vaporization, 44kJ/mol, and it is nearly impossible to recover this heat. When you burn hydrogen in an ICE, you are spending a lot of energy essentially boiling water. You get 286kJ from burning a mole of H2 gas, but you lose 15% of that heat because you cannot condense the water vapor.

Comment I want less video (Score 2) 189

I guess that is one reason I like Slashdot.

I dislike the video content on I don't need a video of a reporter reading a story. I can read myself. In general would rather read a story and see a high-quality still picture than a tiny compress video.

Don't get me started on pictures or videos of text.

Everything Zavodnik did was pretty brilliant. You would not want to play poker with this guy.

He threw the printer away to make himself seem ridiculous. That was planned. He wanted to look like a crank. What kind of idiot throws away evidence before taking you to small claims court? Then he sends you a weird letter wanting you to admit that you owe him $600,000. What do you do? What would you do if I sent you a registered letter saying that I wanted you to admit to owing me $600,000? You would ignore it like any sane person would...

The message used to say something like "Do you want to install Windows 10 now, or do you want to schedule your Windows 10 installation for later?" Clicking the X was the only way to say 'neither'. Now clicking the X says yeah, go ahead. You don't see this as sneaky in any way?

Remember a month ago when people were saying that there was no way you could accidently consent to installing Windows 10?

The only sane solution is to turn off all updates from Microsoft.

Pump storage works great as long as you have a mountain, a lake, and all the permits are in place. There are maybe a dozen places in the US where pump storage is viable. Batteries will be needed for EVs and the batteries in the EVs will massive controllable storage facility. When the batteries are no longer suitable for EVs, they can be re-purposed for grid storage for a few more years, and finally they can be recycled.

Both houses were damaged by the tornado. From some other reports, the house that was torn down was unlivable at the time.

It usually is often easier and cheaper to tear down a structure and start over that repair one.

I am sorry the owner lost some personal items, but it was a mistake and mistakes happen. No one was hurt. It can all be fixed. It really is not that big a deal.

Comment Are lanes needed on small roads? (Score 1) 602

In residential areas where there is a 25MPH speed limit, is it safer to drive on the far right side of the road or is it safer to drive near the middle of the road? Obviously, you pull to the right to pass on-coming car, but what is there is little to no on coming traffic? The 'unexpected' tends to come for the sides of the roads and driving near the center of the road increases visibility and gives you more time to react. There is no real danger of hitting an on-coming car, both drivers have plenty of time to move to the right.
