Comment: lawsuit in 3..2..1 (Score 1) 126

Someone crashes his bike into a cement barrier and hits his head, smashing the helmet and rendering him paralyzed. Family files multiple lawsuits against multiple companies including the maker of this device built into the guy's helmet because it "distracted him", or because pieces of it pierced his skull. It's just a matter of time. I hope Skully has factored this into the price.

I see comments like this all the time, but in my own personal experience paypal protected me as a seller from a fraudulent buyer who tried to steal several hundred dollars. Although the process was not quick, in the end Paypal discovered the truth, and I'll continue to use and recommend the service.

why not just burn the ammonia?

Actually this is possible. From wikipedia:

Ammonia cannot be easily or efficiently used in existing Otto cycle engines because of its very low octane rating, although with only minor modifications to carburetors/injectors and a drastic reduction in compression ratio, which would require new pistons, a gasoline engine could be made to work exclusively with ammonia, at a low fraction of its power output before conversion and much higher fuel consumption

I leased panels for my house to charge my all-electric car. Since I paid for the 20 year lease in advance, my power costs about 10 cents/kwh over the 20 year period. I don't know where you live but in my area this is about half the current average cost of electricity, and the price per kwh is sure to increase over the next 20 years (for everyone else). Since the system is grid-tied I don't need a battery for the house. As an added bonus I never have to wait in gas lines. I'm actually saving money by not buying any gas.

Prisoners should be treated humanely. I get that. What I would like to know is how many prisoners who were released after being confined in solitary for a long period of time are repeat offenders. I suspect that, given the horrible conditions of solitary, most of them would do anything to avoid going back to prison. If that is true, then it really is an effective rehabilitation technique, and ultimately reduces crime.

Actually yes, solar can be the whole solution. In my case I generated 538kwh in the past 30 days with 16 - 250w panels, in the dead of winter. My all-electric car uses about 300kwh per month. In the summer I generate far more power than I need, and this compensates for extra power I use in the winter.
