After reading this through all the way I had a couple thoughts I hoped to share...
THe thorium powered vehicle thing seems like a nice concept, however the reality of it based upon the sources cited seems rather far fetched. (The validity of the site that is proposing this Thorium Vehicle, that is)
As to electric cars and how "great" they are, well they aren't the be all end all.
They all still use huge cell stacks made from the same cells that power your laptop or your power drill. (18650 cell typically the LiMn kind and rated at about 10C per cell with an average of 12-1400mAh capacity)
Basically, battery technology is crap right now. There are advances being made in the field, but they are slow to come and require more time to mature and come to the consumer end of the market.
Not to mention disposal of the aforementioned cells at end of life...
Solar power is nice and can net measurable savings, but this is also at a great initial cost on the end of the consumer as well as a terrible efficiency rating over all as the market and tech presently stands.
On to the discussion of 300+Bhp vehicles being overpowered or ridiculous, well I have to respectfully disagree.
You are assuming that solely due to the power generation capability
that it is not harnessed or limited effectively. Also not being considered are the drivetrain losses that occur to get the power from the main power plant to the tires, which in a 4 wheel drive (or all) vehicle is then increased. Typically it is around 14% loss.
Power in a vehicle is also subject to how that vehicle is used as far as what is called for.
So any developments in that area will be capped by the intended use.
