That's a great start, but from my understanding that legislation stops at $50/ton, which is a problem. You really need it to keep ramping up to get the price discovery. It's possible that at $51/ton the problem would sol

Not all MRI machines are equal, though, so it's hard to tell without specifics. A low field 0.2T machine might be $150k. A full bells+whistles 3T machine might be $3M.

Successful companies pay a lot in taxes (through employment if nothing else), so technically the government does see dividends (albeit in a non-traditional form). However, given the nature of government, it should technically be enough if s

Apologies :). However, you really cannot compare coal to renewables directly, since it's an apples to oranges type comparison. If you include externalities like a carbon tax in the cost curves then the you really need to understand t

That is an excellent point, and very difficult to model. Maybe more importantly, the supply curve for natural gas is also very difficult to model. In Europe NG is expensive, but as the demand drops the price will likely decline sharply (the

I'm not sure why you framed this as an us-vs-them fight. Hypothetically, each investor has some internal valuation for your startup, and is willing to take <x> risk. Giving those investors preferred shares reduces that risk, whic

I said the death of 20 people a year does not make it the greatest threat to public safety in the state, not that it isn't a tragedy to be mitigated. Objectively this is true, does that make you upset?
