How Would You Survive A World Without Fossil Fuels?
The Green Optimistic, 5 hours ago
Have you ever realized how much we depend on fossil fuels? Fossil fuels are involved in practically every single activity known to modern man. I've been laid up in bed a couple of days with the flu, which gave me some time to watch some documentaries I'd been trying to …The post How Would You ...
Fuel Cell Vehicle Myth Seven - Hydrogen Fuel Stations are Too Expensive!
The Green Optimistic, 5 hours ago
Hydrogen fuel cell vehicles, just like hybrid electric vehicles and conventional vehicles, would require refueling stations, but aren't they too expensive to build? Like all vehicles on the road today, hydrogen fuel cell vehicles store their fuel onboard, but needs to get that fuel from somewhere el...
Climate Change - Pay Now or Pay Forever
The Green Optimistic, 5 hours ago
Climate change, within the last couple of decades, has become more certain to cost us perhaps billions or trillions of dollars, yet there are delays in addressing the problem to the proper degree. As with so many other things, take heart health, for example, addressing the problem ahead of time R...
Nanotechnology Could Make Pure Lithium Battery Possible
The Green Optimistic, July 29, 2014
Currently, most portable devices use lithium-ion battery technology, in spite of the fact that a pure lithium battery could offer much more capacity. The problem is with longevity, as a pure lithium battery may have 300% the capacity of a lithium-ion battery, but it can only be cycled between 50 ...
Fracking, "Done Right," says UK Business and Energy Minister
The Green Optimistic, July 29, 2014
Three years ago, unusual seismic activity forced fracking operations to cease operation in many parts of the UK, but that ruling is being overturned. Starting today, oil companies can bid on shale gas exploration rights, vis-?-vis, fracking, which is short for hydraulic fracturing. On the one hand, ...
Fuel Cell Vehicle Myth Six - Hydrogen Fuel Storage and Delivery is Dangerous
The Green Optimistic, July 29, 2014
Hydrogen fuel cell vehicles may seem like a new technology, but is hydrogen fuel production, storage, delivery, and utilization unproven technology? Actually, this has been around for decades, the proton exchange membrane fuel cell dating back as far as the 1950s, invented by General Electric. The f...
Fuel Cell Vehicle Myth Five - Fuel Cell Vehicles Use Liquid Hydrogen
The Green Optimistic, July 28, 2014
We've been filling up conventional vehicles with liquid fuel for over a century, so it only makes sense that hydrogen fuel cell vehicles use liquid hydrogen fuel, right? The upcoming Toyota FCV, for example, uses composite H2 storage tanks at pressures of up to 875 atm (12,859 psi), giving the ̷...
BMW i3 Owners Treated to Free Fast-Charging
The Green Optimistic, July 28, 2014
BMW may not have been first, but the company has been working hard to increase awareness and adoption of electric vehicles, such as the new BMW i3. While many people may see only limitations when it comes to electric vehicles, automakers such as Tesla Motors, General Motors, and BMW are …The p...
Climate Change vs California Wine
The Green Optimistic, July 28, 2014
Climate change takes the blame for unusual weather anomalies around the world, but it could also result in wine lovers' bottles being a little less backbone, balance, or aroma, depending on how the Napa Valley drought affects next year's grapes. Since the beginning of the Industrial Revolution, when...
Fuel Cell Vehicle Myth Three - Hydrogen Fuel is Expensive
The Green Optimistic, July 25, 2014
If cost is a measure of how willing people are to get into alternative fuel vehicles, such as fuel cell vehicles, won't expensive hydrogen fuel effectively cancel out any environmental benefits? We've already discussed how much it costs to power a fuel cell vehicle, and it's actually cheaper than ba...
