Your Mileage May Vary (and other rants)

Recommended Posts

Battery technology will get cheaper and more powerful in the coming years. Regular ICE are a mass product and "very" cheap to make and they have been made and improved for 100 years. Now how old is really usable battery technology?

Well actually electric cars have been around as long as gas ones. The word "really" is the catch and very subjective. The energy density by weight of batteries is still well short of petroleum products. We are in a transition away from petroleum and hopefully other fossil fuels. It's occuring quite rapidly from a societal point of view but slowly from advocates points of view.

Toyota has the only true Hybrid SUV, however the difference is roughly 6 MPG between the ICE only and the HiHY/rxwhateveritis, but the cost difference, even used far exceeds any savings it would generate. All it does is give you that false sense of being green. The lexus twin is the 400H(or whatever it is now) and it was NOISY, and way under powered, and did not get as good MPG as it claimed.

The word "Fuel" is a tricky thing. Electricity and hydrogen are not fuels, they are energy transfer methods. A fuel is something that will produce more energy than it takes to prepair it. Wood snd petroleum products are an example that release stored chemical ( solar ) energy when ignited. Hydroden does not exist on Earth unbound from a molecule so that it can be ignited. Much more energy must be used to produce free hydrygen than it produces. Corn ethanol is similar. Nuclear energy I'm not sure of. Safeguards probably reduce it's net energy output close to a wash.

The ICE underwent a continuous improvement since it's invention through to today. The lead acid battery didn't change much for a hundred years. Better battery technology has only arrived in the last few decades
