The GrowHaus is a great community plan that encourages smart sustainable growth and involvement. It is one small stepping stone in the right direction of new and much needed urban re-developmental plans with the use of new technological sustainable systems such as aquaponics.
Safety is a topic that can never be covered enough. For all of those people who have stood at the top of an extension ladder, on a roof’s edge, or participated in setting floor joists or roof rafters, there is nothing quite like being armed with the right equipment in case of an accident. This is true whether you’re 6 feet off the ground, or 100 feet. Guest writer Eric Blair provides GBE with me useful information concerning safety harnesses and rigging.
A fermentation technique once used to make cordite, the explosive propellant that replaced gunpowder in bullets and artillery shells, may find an important new use in the production of advanced biofuels. With the addition of a metal catalyst, researchers at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the production of acetone, butanol and ethanol from lignocellulosic biomass could be selectively upgraded to the high volume production of gasoline, diesel or jet fuel.
