Liquid fuel can be continuously cleaned of the contaminants that spoil solid fuel.
The term hybrid is used because this type of rocket motor uses neither all-liquid fuel nor all-solid fuel, but a combination of both.
If you are using solid fuel, add a few lumps of charcoal or a few briquettes every hour, just enough to keep the fire going.
Would eradication of solid fuel cook stoves eliminate indoor air pollution?

The hybrid design which Mr Jubb has come up with uses a solid fuel called hydroxyl-terminated polybutadiene, a form of synthetic rubber used to make things like aircraft tyres.
Households with oil-fired central heating, and those using solid fuel or liquid petroleum gas to heat their homes, are much more likely to be in fuel poverty than "on-grid" households.
Syria and Iran have armed Hizbullah with some 40, 000 missiles and rockets, including hundreds of Scud missiles and guided surface-to-surface solid fuel M600 missiles with a 250 km range and.
It is hard to imagine that it is mere coincidence that North Korea's actions came just a week after Iran tested its solid fuel Sejil-2 missile with a range of 2, 000 kilometers.
Frankly, I believe that solid oxide fuel cells are the better technology in the long run, but Fuel Cell Energy owns 43% of the shares of VERSA Power that also makes solid oxide fuel cells.
The acquisition of MIRV and solid fuel technologies, the deployment of increasingly longer-range mobile missiles, the development of neutron warheads, all indicate a broad-based, and well-financed nuclear modernization program....China has started to construct a new submarine to carry longer-range missiles with warheads based on the design of the Trident W88.
CENTERFORSECURITYPOLICY: Summary of the Center for Security Policy's High-l
According to the World Health Organization, solid fuel use causes 1.6 million excess deaths per year globally, especially among women and children, while waterborne disease is one of the leading global killers, ending the lives of over 3 million annually again, many of them young children who lack access to clean and safe water supplies.

As a solid-fuel rocket, this could be fired at short notice from mobile launchers.
This is evident in the strides Tehran has recently made with solid-fuel rockets and with space-launch vehicles.
Another is to use powerful solar cells to collect sunlight in conjunction with an efficient solid oxide fuel cell.

Solid-fuel reactors are atomic pressure cookers, with the constant danger of high-pressure ruptures, meltdowns, and the forceful ejection of radioactive material into the environment.
Solid oxide fuel cells have notoriously faced challenges with durability, since they operate at very high temperatures, which the Bloom box will also have to overcome to prove profitable.
